With the advent of Blackrose custom HBOOT which gives us S-OFF, we can now resize the MTD partitions of our N1. This method is the one used by lbcoder in the Desire thread where you patch the recovery and boot in order to pass modified MTD partition information which supersedes the one provided by the SPL. Using this, I've managed to increase my userdata partition by ~50 MB by taking ~50 MB from the cache partition.
These instructions are for advanced users only. This will involve hex calculations and command line instructions that are not for the faint of heart. I don't believe it's dangerous though so anyone could still try since I will try to make these instructions as detailed as I possibly can.
What you need:
N1 with Blackrose HBOOT (I'm not sure this is needed though after I read more in-depth about the patch)
hex calculator (or a pencil & paper if you want to do it manually)
adb
fastboot
unpack-bootimg.pl
mkbootimg
recovery.img <- in my case I used ClockWorkMod 5.0.2 from here
boot.img <- taken from CM zip (in my case my KANG)
Partition Layout:
0x000003ee0000-0x000003fc0000 : "misc"
0x000004240000-0x000004640000 : "recovery"
0x000004640000-0x0000049c0000 : "boot"
0x0000049c0000-0x00000dac0000 : "system"
0x00000dac0000-0x0000139c0000 : "cache"
0x0000139c0000-0x00001fe00000 : "userdata"
Partition Sizes in Hex:
0x0000000e0000 : "misc"
0x000000400000 : "recovery"
0x000000380000 : "boot"
0x000009100000 : "system"
0x000005f00000 : "cache"
0x00000c440000 : "userdata"
Step-by-step Instructions:
A>Backup your current system: (OPTIONAL)
*I'm assuming you're using CWM 5.0.2 for the backup step since I tried using 3.X and the restore didn't work
1.) Boot your N1 into recovery using either adb reboot recovery or through the bootloader
2.) Backup your current system (I'm going to assume you know how to use your recovery for this)
B>Calculate new MTD parameter values:
*For this example I'm going to transfer ~50MB of cache space to my userdata partition:
1.) Since I know the cache partition is ~100MB in size, I'll just divide the hex size in 2:
0x5f00000 / 2 = 0x2f80000 <= this will be our new cache size
**Note that there is a minimum of 0x20000 (128k) for a partition and the size must be divisible by it which is why I'm playing safe and just dividing the original number in order to get an easier value for this example.
2.) Add the new cache partition size to the original cache partition starting address to get the new starting address of the userdata partition:
0xdac0000 + 0x2f80000 = 0x10a40000 <= this will be the new starting address for userdata
3.) Get the new userdata size by subtracting the new starting address of userdata with the ending address:
0x1fe00000 - 0x10a40000 = 0xf3c0000 <= this will be the new userdata size
C>Create a new recovery.img file which uses the new values:
1.) Breakdown the recovery.img file into it's kernel and ramdisk components using unpack-bootimg.pl:
.\unpack-bootimg.pl recovery.img
*This will yield 2 files and 1 directory. You can delete the directory since we only need the files.
2.) Rename the kernel from the recovery.img-kernel.gz made from unpack-bootimg.pl to recovery.img-kernel.
3.) Create the recovery-new.img file using mkbootimg with the new MTD command embedded:
mkbootimg --cmdline 'no_console_suspend=1 console=null mtdparts=msm_nand:[email protected](misc),[email protected](recovery),[email protected](boot),[email protected](system),[email protected](cache),[email protected](userdata)' --kernel recovery.img-kernel --ramdisk recovery.img-ramdisk.cpio.gz -o recovery-new.img --base 0x20000000
*Note that the values for cache starting address, userdata starting address and userdata size have been changed to the newly calculated values in the previous step.
**This will yield recovery-new.img which will be used in the next steps.
D>Create a new boot.img file which uses the new values:
1.) Breakdown the boot.img file into it's kernel and ramdisk components using unpack-bootimg.pl:
.\unpack-bootimg.pl boot.img
*This will yield 2 files and 1 directory. You can delete the directory since we only need the files.
2.) Rename the kernel from the boot.img-kernel.gz made from unpack-bootimg.pl to boot.img-kernel.
3.) Create the boot-new.img file using mkbootimg with the new MTD command embedded:
mkbootimg --cmdline 'no_console_suspend=1 wire.search_count=5 mtdparts=msm_nand:[email protected](misc),[email protected](recovery),[email protected](boot),[email protected](system),[email protected](cache),[email protected](userdata)' --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz -o boot-new.img --base 0x20000000
*Note that the values for cache starting address, userdata starting address and userdata size have been changed to the newly calculated values in the previous step.
**This will yield boot-new.img which will be used in the next steps.
E>Flash the recovery-new.img:
1.) Boot into bootloader and use fastboot command to flash the new recovery:
fastboot flash recovery recovery-new.img
F>Make system operational:
1.) Boot into recovery mode.
2.) Erase everything (factory reset)
3.) Either:
- Flash the ROM you took the original boot.img from OR
- Restore the backup you made previously (this only works (or has been tested) on CWM 5.0.2)
4.) DO NOT REBOOT YET!!!
G>Flash modified boot.img:
1.) Use adb to reboot to bootloader directly from recovery: (this is for safety since if you boot from an unmodified boot.img you'll have to start from F again.
adb reboot bootloader
2.) Use fastboot to flash the new boot image:
fastboot flash boot boot-new.img
3.) You may restart normally.

2 Questions:
Is the userdata space where downloaded apps go?
why didn't you choose any other partition to transfer empty space from?

thank U. Now I have no need to buy a new phone because of constantly running out of memory
Does it mean that every time I flash a new kernel, the whole effort will go waste?
Also, can I use the same procedure for Amon RA recovery??

For that you need to do only steps D, F and G. If you flash only a kernel which uses koush's anykernel updater, you don't need to do anything.

One more silly question
Will the following procedure work.
1. Flash any ROM.
2. Then flash the modified boot.img (which may not belong to that ROM).
3. Then optionally flash the desired kernel.

Yeah. That would work since you're replacing the kernel anyways. What's important is that the kernel is compatible with the ROM.
Well done IR cannot wait to resize my data partition..
Okay, I extracted the recovery.img file, now when I try to extract recovery.img-kernel.gz, it gives the following error: not in gzip format. Exactly same happens for boot.img. I tried extracting it with different extractors on windows and ubuntu, nothing worked. Pls help.
I don't like using MTD because over time you will notice lag. If your already using sd-ext then your data is basically not being used. And I believe that cache never gets past 50% usage. Just putting in my two cents

Found the problem. It seems it was never compressed in the first place. Ark sees this and just copies the file without the .gz extension.
*Instructions edited accordingly.
I may sound a bit noobish, but I'm facing one more hindrance:
How exactly do I run the mkbootimg file in the ubuntu terminal? I mean, can you give me the exact syntax?
I was facing a similar problem with the perl script, but then I found a solution on google, but didnt find anything for the mkbootimg. Can I run it under windows cmd?

I already posted the syntax in the instructions. You just need to make sure the mkbootimg file has execute permissions in order for it to run.

Wait, I found it. It's a bug. Thanks! I'll edit it when I get home. For now, please double check the values by reopening the made file before flashing. If the values are incorrect, please DON'T FLASH!!!
Here, i've quickly compiled three MTD utils ( git://git.infradead.org/mtd-utils.git ):
nanddump, nandwrite, flash_erase
So far tested nanddump - works , i was wandering what's inside

mtd3: 00040000 00020000 "LogFilter"
mtd4: 00300000 00020000 "oem_log"

Nothing interesting, actually.
--
nandwrite should enable you to write boot, recovery, system and firstboot right from android system (i don't think that it's good idea, but anyway).
--
Readme:
MTD-Utils 1.5
Please use with extreme caution!

Streak 5, dump example for recovery:
./nanddump /dev/mtd/mtd1 -f /sdcard/mtd1

I was able to switch recovery on the fly, having /sdcard/CWM.img (CWM port by TheManii) and /sdcard/SM.img (Old and trusty StreakMod):
/system/xbin/flash_erase /dev/mtd/mtd1 0 0
/system/xbin/nandwrite /dev/mtd/mtd1 /sdcard/CWM.img
Reboot, checked if works - it does
Back to StreakMod:
/system/xbin/flash_erase /dev/mtd/mtd1 0 0
/system/xbin/nandwrite /dev/mtd/mtd1 /sdcard/SM.img
Changelog:
Added flash_erase
can you please guide how to flash this
should i flash this in streakmod recovery and will it wipe my current streakmod with cwm recovery ?
This zip pack should not be flashed.
This tools can operate on (at least) Streak NAND flash partitions, i.e. read, erase, write.
It contains three android binaries - you should extract them and place, preferably, into /system/xbin
Change permissions on al this files to 755 - like:
chmod 755 nanddump
Now, you should be able to flash boot(kernel) and recovery right from working Android system.
I've given an example in first post.
hunderteins, if you reading this - would you give mtd5 from your device?
I have it empty and wander what image format it should have.
Where is AMSS, DSP and stuff?

According to this article:
http://forum.xda-developers.com/showthread.php?t=542688
this areas can be regained and hmmm, altered?
AMSS, DSP, service tag, provider lock and some other interesting stuff could be there!

Well, it seems that nothing, but this makes me feel dumber than usual
I didn't try cat :laugh:
flash_image should be the built in way of writing to mtd and raw emmc partitions, though we rarely ever discuss flash_image
try reading the raw nand at the beginning of it, thats where its stored on emmc devices, and there is unmapped space in the beginning
54mb should be approx enough shouldnt it? (not at pc to verify file sizes of the firmwares)
you could compare to the spro's map i guess, its an emmc device, but not a qisda one.
if i had the mapping for the "streak2 5" that would be the best to compare to, but i dont
is there any way to verify the mem locations are correct? i have the exact emmc layout for the s7/s10 because nvflash provides it if asked.
but there is no standardized tool for qualcomm chips, ill assume they're correct
also: at least on filesystems you should use dd and not cat for the fact that cat drops the final byte or something to that degree.
i dont recall if it applies to yaffs2 but it should for ext, it shouldnt matter for raw mtd partitions
hmmm iam still confused need to wait more to know this all

You see, tools operate on logical partition level (i think flash_image is a userspace tool that uses mtd partitions, same as mtd-utils).
And kernel doesn't provide a raw device for NAND (i'd love to be wrong though).
I'll try tomorrow to supply kernel an MTD table via mtdparts parameter and check ow it goes.

mtd devices are character devices, dd works only on block devices.
I thought apply_patch is the first choice for writing into mtd from the commandline.
there should be a kernel option near mtd in menuconfig where you can setup the mtd-layout manually on the kernel commandline. Thats where I would tinker, when I wouldn't trust atag.
Yes, " Command line partition table parsing" enabled in kernel.
Also, MTD seems to have enabled char read/write access, that makes MTD-Utils a bit obsolete
OK, i'll report if i'll find something interesting.

StreakMod recovery.
Kind of side-effect from my test:
StreakMod with replaced kernel (Phoenix, +rotated matrix).
http://n0p.8bit.fm/streak/smd.img
Works in portrait mode (interesting, looks like out matrix was rotated in kernel for 270 in kernel)., no it's different static surface flinger.
Could you make a dump of dt? (and which version of DT you have)
DT obviously isnt straight flashed during a stock update, wonder how it's transformed on install.
I believe it's 407.
http://n0p.8bit.fm/streak/DT.zip (zipped just for integrity)
Which kernel was it that you modded for this? (I mean the exact revision), did you upload it?
I'm keen on dumping everything and attempting to do a write up on it.
I've done a device fixing guide for the S7:
[Guide][Technical]Restoring your device specific data (including Service Tag)
Context: someone uploaded an nvflash dump that also included their device specific data (imei, service tag, etc)
and dozens of people ended up with cloned devices because they blindly flashed it without understanding nvflash.
I would like to do a feasability study to see if it would be possible to restore jtagged S5's (ie ones with blanked IMEI, service tags)
I'd need multiple dumps to compare the unique data, very least we'd be able to learn a thing or three.
I'm guessing that JTAG was always able to access these sections of the nand, and that they were writing bad data to it during restore
(as the jtaggers didnt have a good copy from a working s5?)
Your DT dump is definitely different from the raw DT.img, 366 and 407's DT only differ in their dates, they're more or less byte identical.
It's likely due to DT being "installed" and not mere "extracted" (ie DT_update on stock update)
It's simply a kernel parameters, altering mtd partitions - and you can take them from smd.img I published earlier. There's three unkX partitions mapped to holes in nand layout.
Or I can build a cm7 kernel with this options.
--
Seems like contents or mtd partitions are crc checksummed. Anyway, having full amss and dsp dump should enable us to write'em right on rom flashing and that's good.
For the actual firmware files, it's not important as I'm mainly interested in analyzing the device unique data.
I dont believe the unique data has any checksums, as devices can still boot with blank IMEIs and service tags,
unless it also just so happens that they took that one instance into account.
The S7's data definitely isnt checksummed, but it's a rather different platform.

Tip From the Author,
Some of you may have noticed that i did not start the original thread with a question, I did something my mentor taught me at around 9 years old but didn't put into good use until much later in life.
The tip is write things down as a question for yourself, in the writing process you get to pass the information past the part of your brain that interprets information, virtual sounding board, before posting as a question for others.

Hi All
As i mentioned on this thread http://forum.xda-developers.com/showthread.php?p=32231827#post32231827 i will be attempting to come up with a home grown debrick solution for a SHV-E160L samsung note from korea.
I will use the forum to document what i am doing, i am very new to this so correct me please if i am wrong. I have never done Android dev work at any time but i have a very good understanding of the logic behind it all. `
Things i Have :-
Phone ( SHV-E160L)
bus pirate v3 with jtag firmware
openocd compiled on ubuntu and centos 6
smd jtag adapter and relay wire ( magnetic wire)
things i still need :-
openocd target config file for MSM8660 Snapdragon cpu (and a better understanding of eMMC access, how to load boot loaders either into ram or eMMC or trigger fail over boot to sc-card, USB via software or X0M/Boot pins)
assembled jtag (it's the smallest soldering i've ever seen)
.PIT file for 32GB model (if someone could pull the .PIT file from a working unit I would be happy, specify your radio/kernel versions when uploading)
micro fine solder iron tip and 20w iron (i've got 60w but too high for this type of work)
Does anyone have a idea of the SD-CARD partition layout, files for snapdragon devices, google has given me much for other devices but not a snapdragon .
Another question, I've used the USB jig to trigger 301K mode USB-Factory and seen no activity in dmesg for usb devices, i've yet to try windows, does windows/linux behave in a different way when it comes to usb , as in windows see's the qualcom usb mode but not linux ? does the usb client device always start the comms?
using the 615K usb jig i get nothing too, no pbl message from samsung (hence i am led to think is's the pbl/sbl thats damaged)
My understanding up boot is as follows
iROM code
This loads basic settings to boot the PBL (iROM is in rom) the PBL is loaded into radio(modem) cpu and then loads the SBL(s)
PBL/SBL stored in eMMC at address ????? (need to document the address for the masked access to eMMC and jtag/openocd access unmasked access)
Once the SBL is loaded you with have the ODIN mode (USB/UART)
from what i can see of commercial JTAG boxes is the access the radio cpu via jtag, write a new PBL/SBL to the eMMC then halt/reset cpu which now loads the new bootloaders, (resurrect dead body)
The openocd TAP id for the cpu should be 0x105310E1 but thats a number i got from a riff box log, not any actual testing ( still need to solder the fine pitch connector)
Here is a log from a riff box, not sure if the address's are usable accross to opencd

I did notice one thing, the riff box opens the serial port, i wonder if they load PBL+SBL into memory, reset the cpu, then using the serial connection activate download mode ? (like on the captive)
I also dont know how the cpu (jtag TAP id? ) and flash variables translate accross to openocd as ive not found a target config file yet ( or my searching is wrong)
in the full stock Firmware I was able to extract the .tar file which contained,
Code:
amss.bin <-- application cpu boot files ?
boot.img <-- kernel/initrd ramdrive
mdm.bin <-- modem cpu boot files
recovery.img <--- recovery image
system.img.ext4 <---- rest of the system applications
so i think we have the two cpu firmware/boot loaders in the .bin files, these bin files are just fat32 images, to access in ubuntu use
Code:
mount -o loop mdm.bin /mnt/mdmmountlocation
My guess is my first approach is getting the right PBL/SBL into the system and getting some feed back via uart, i have the jtag pinouts and further reserach says there is a UART2 on the jtag header, so when soldering up my jtag adapter i will include all pins if i can and sniff for serial logic, i happen to have a Open source logic sniffer, great tool as i do a lot of hacking into serial devices like scales and till printers .
back to topic.
When i do get to the jtag part at a minimum i should have access to the modem radio, afaik jtag devices connect in chains and most of the IC's that have jtag on the phones board all should link to the master device (i am thinking it's the modem cpu, no application) and that the Two cpu's share the eMMC memory some how, or it could be one cpu loads it into the other (it is connected via jtag down the chain) .
hopefully someone could correct me there.
Most of this is theory and my guess work, correct me if you find a mistake. most of the research is only over a few days too so i am far from finished there, does not help that most of the users speak a language that google translate just does not have a flair for.
Most of the info seems to suggest the modem cpu is the first inline so i decided to look further into the files there, notice the mdm.bin file is 23Mb, thats large, when mounted i notice the is a folder called 'image' ( amms.bin has folder called IMAGE , note the case difference, dont yet know whay)
in image folder we have :-
Code:
1.3M Sep 30 13:07 AMSS.MBN
35K Sep 30 13:07 DBL.MBN
2.2M Sep 30 13:07 DSP1.MBN
19M Sep 30 13:07 DSP2.MBN
40 Sep 30 13:07 EFS1.MBN
40 Sep 30 13:07 EFS2.MBN
40 Sep 30 13:07 EFS3.MBN
295K Sep 30 13:07 OSBL.MBN
Ah, i see amss.mbm , that must be the boot loader for the application cpu, DBL.MBM seems to be the PBL , OSBL.MBM could be the SBL
then there is the DSP/EFS files, I did do the command strings on all the files,
DBL.MBM does not have any text in the file that points to being able to do UART on boot, all text seems internal like pointers and references to the original build files e.g
Code:
D:\Q1LGT_MDM\MDM9600\modem_proc\core\boot\secboot2\dbl\target\mdm9x00\src\dbl_ddr.c
9x00B-SCAQSVZM-31613102
D:\Q1LGT_MDM\MDM9600\modem_proc\core\boot\secboot2\dbl\target\mdm9x00\src\dbl_sahara.c
but it also does contain data like this
Code:
auth_image
@[email protected]
@configure_hw
@flash_init
l0:eek:SBL
load_osbl_img
@DBL, Start
hw_init
so it looks more likley that dbl is first in the chain, it refers to loading osbl and configure hardware, i wonder if it means USB/UART at this stage or setting up ram and other GPIO's
in OSBL.MBM we have more interesting text
Code:
MbP?
Unable to attached to ChipInfo DAL
SAMSUNG
TOSHIBA
Flash: Failed to do initialization for probe!
ONFIx
0:ALL
Flash: Multi 2X page read not supported!
Flash: Multi 2X page write not supported!
boot_qdsps
OSBL
hw_init
hw_init_secondary
OSBL, Start
create_vector_table
ram_init
retrieve_shared
clobber_add_protection
mmu_flush_cache
OSBL, End
OSBL, Delta
osbl_sahara_load_amss
osbl_sahara_load_dsp1
osbl_sahara_load_dsp2
osbl_sahara_load_ramfs1
osbl_sahara_load_ramfs2
osbl_sahara_load_ramfs3
smem_boot_init
so it is looking more and more like DBL then SBL which then loads all of the other parts , also if you notice EFS1/2/3 are all tiny 40byte files, now i see why, they are loaded as ram-drives, so i assume those file set out the basic EFS file system in the ram.
again from research the boot stages are often counted as 3, i am assuming the real first part is in rom of the cpu (is this what triggers the qualcom download mode ) that loads DBL from eMMC and chain loads SBL
Now looking around the riff forums i see the list the info in a different way
Code:
Partition 0
SBL1
SBL2
Partition 1
RPM
SBL3
eMMC APPSBoot
TZ
.PIT
Click to expand...
Click to collapse
TZ i think is Trusted Zone
RPM - Power manager ?
now how this translates to file name from full flash and to mmcblk0p1 partitions i have yet to find out, i still dont have a .PIT file from a 32gb model
More updates to come,

CPU Boot order updates
So my digging has taken me back round to some of me early searching which i forgot about , hardware level seems to support the qualcom usb mode, but it can be disabled by manufacturer, so even if you find a resistor to the BOOT_CONFIG GPIO and ground it , it still may not work, and you could toast your board. once the qfuse is gone for that track, the maker can now use the gpio for anything else, it no longer controls the iROM branch choice ( CPU:do i start usb first or last?), it my thinking that on the first board sent out by the designers for a final production run ( those first public devices) they keep the option open to print off DEV models by changing the resistors/value of while the hardware stays same, not to be confused with dev board, that is pin/track simlar but is used to design the software mainly, sometimes hardware debug but as you change the hardware between the dev platform and production this is less helpful, google new.intrinsyc.com and apq8060, they produce a dev board that is the same as the device we hold, but everything is broken out for testing so don't expect to see this left in a bar for you to e-bay.
EDIT:
Above I refer to a dev phone and dev board, these are SURF and FFA, FFA is form factor accurate and SURF is Subscriber Unit Reference.
Here is the link, http://forum.xda-developers.com/showthread.php?t=1856327
Now from what i see, it's the same(edit:simlar) X0M pin setup as other phones, ground the right pin, reverse boot order, but this maybe two pins in the snapdragon,
[copied from other link]
Simplified table:
Code:
------------------------------------------------------------------

------------------------------------------------------------------
0b00000 Emergency Boot from SDC3 (SD) followed by USB-HS
0b00001 SDC3 followed by SDC1 (eMMC)
0b00010 SDC3 followed by SDC2 (if used)
0b00011 SDC1 (eMMC)

So if 0b00000 is EM boot and the docs say the the two gpio's that control this (if qfuse not blown) are taken high then it's 0b00011, so grounding those two resistors should give us 0b00000 or EM boot, the cpu docs also say they are internally grounded, the schematic says the voltage goes throught a 10k resistor, so grounding that side of the resistor that 'goes' to the cpu should change the boot order, but before trying this out, remember if you get the live side of the resistor the is no resistor between your probe and ground, that full current, short, blown, no more johnny 5.
Have you managed to unbrick the E160L?

I think my E160L got a real brick today after I tried to flash a modified Rom downloaded from a Chinese forum. It can not be powered on after rebooting (installed successfully). I desperately need advice now on how to deal with it.

Do you have any backups like nandroid ? does the 3 button boot still work ?
Regards
Have you looked into using ort-jtag. It's only about $150 (USD).
I've been looking into this myself for low-level debugging/bootloader development on SGH-T959V and SGH-I717.
All three of these devices are supported by ort-jtag and have header connectors for the jtag pins.
So I'm also getting some of these from digi-key, and making a small receptacle, much like in AdamOutler's captivate bootloader development thread. (search for k-ww)
Again, ort-jtag does support the SHV-E160L. (search that link for SHV-E160L)

does any one want the dump that can reverse it ?
Dumps & execute address
I also need the help of other SHV-E160? owners, i need dumps from working phones, i managed to create a 8660_msimage.mbn and flashed it, but i was using i717 bootloaders and i dont think they will work, i need working dumps from working phones, starting with partition table layout, sbl1.mbn and sbl2.mbn
Does anyone know if the is is correct
SBL1 exec address 0x2A000000
SBL2 exec address 0x2E000000
as i can upload the sbl to 0x2a000000 but not the sbl2 to 0x2e000000
i can also upload the tz.mbn to 0x2a020000
i am trying to use sec boot 3 based call stack but am unsure of the real exec values
Ive seen in another post these values
"
It looks like ours deviates slightly from this.
If the headers are to be believed,
TZ is loaded at 0x2A000000
SBL3 is loaded at 0x8FF00000
APPSBL/aboot is loaded at 0x88E00000
"
the post is
http://forum.xda-developers.com/showpost.php?p=30057296&postcount=243
it does explain why i cant load into 0x2e000000
Progress
So today i made real progress, I have been able to flash a basic program to allow me to access the EMMC, i have taken a full backup and now i need to start scanning the dump for need information,
I still need help from other users so please if you are will to provide me dumps of your working device that would help me a great deal
So Part One is a sucess, I have been able to flash my own code and power on the galaxy note. next step is rebuilding the emmc partition tables, testdisk can find the partitions but is not alowing me to write a non standard partition table (which emmc seems to be formatted with)
Thanks

Hi,
I'm stuck with the same problem can you tell me what image you use to the phone. I stuck here. I' m really don't know what to do?
Thank you for your help.

First thing i must say is dont flash your phone just yet!! walking blindly into this could render your phone useless due to certain data being lost for good.
if you still wish to continue i will upload a basic guide and files. My method is still in development, it has many bugs ( i flashed the phone with i717 roms, working, SHV-E120 roms, working, N7000 rom complete fail)
But first some questions,
Which model phone is it?
what happened to get you to the point of needing the flash ? ( i ask so i can trace why the bricks are happening and hopefully fix it)
thank you for your help, I will be waiting your method and your files.
Thank you so much for your help.
My phone is a samsung galaxy note SHV-E160L korean version.
what happen was:
I tried to upgrade the firmware with kies and suddenly the program crash. My phone enter in an error issue with the firmware and said use emergency recovery mode.
I tried the recovery several times (uninstalling kies and install it again but that never work).
So, I download odin and this files to restore the original firmware:
CSC - GT-N7000-MULTI-CSC-OZSLPF.tar.md5
Phone - MODEM_N7000XXLR1_REV_05_CL1144476.tar.md5
Bootloader- N7000_APBOOT_N7000ZSLPF_CL558430_REV02_user_low_sh ip.tar.md5
PDA - N7000_CODE_N7000ZSLPF_CL558430_REV02_user_low_ship .tar.md5
Pit for 16GB - Q1_20110914_16GB.pit
I connect my phone and try to install the firmware again, but odin fail and my samsung became a nice brick.
The phone currently does not turn on, the phone is in download mode and I install QPST and the program recognize the system in download mode.
I want to try your method because other information I collected said that I have to send it to guarantee.
Can I install i717 rom in the E160L?
I will be waiting for your post because sincerely I don't know how to repair it.
Thank you so much.
Hello darkspr1te
First of all, nice work there (though I didn't understood most of the things there, but seems there is some good work going on on our SHV-E160's
On your comment;
( i flashed the phone with i717 roms, working, SHV-E120 roms, working, N7000 rom complete fail)
Does that mean that i717 roms can work on the SHV-E160 devices? Please share if that is the case.
The geeky bits

Ok, as i said it's still a work in progress at the moment.
I used the i717 bootloaders (thats why we have a brick as it's not getting to the aboot loader or little kernel as some other refer to it) and E160 modem and application cpu as my first target is getting odin mode back.
I was able to also use the E120 bootloaders (screen was messed up though )
I've just got home from a very long shift so i will do a full and clear write up ( STILL a work in progress ) tomorrow (20th)
but i will explain the basic now as you do need to download large files before we continue.
First you need to download the same firmware as you were originally on before the brick, The reason is because between versions i suspect there is minor changes in partition tables (that why the n7000 roms brick )
If you dont have the latest QPST (2.7.3xx or higher ) please google for it now, there are many sites that offer it. (links will folllow tomorrow)
also down load :-
ABOOT_SGH-I717M_I717MUGLA2_user_CL875155_REV00.tar (or tar.md5 )
i717-GB-Modem.tar (or .md5)
now my initital work was based off a chinese link for the A820L
http://blog.csdn.net/su_ky/article/details/7773273
To save you the time of many hours of translation and cross reference here is the quick run down
When the phone is in QDLoad mode its because the PBL (Stored in ROM , read only memory) could not start SBL1 or SBL2 , it stores the error in IRAM location 0x3FF18 and then goes to QDLoad fail mode. At this point it has tried uart, sd-card before hand and those failed too.
IRAM is the small built in memory of the MSM8660 CPU, it has not initiated the main SYSTEM ram yet so our memory space ro running code is 87k and 256k (refer to document 8960_boot_architecture.pdf found the unlock bootloaders section.
Now because our partition table and or our bootloaders are damaged (or we have emmc brick bug) we have to rewrite that data again to revive our bricks.
This is where it gets hard, and where my warnings now come into play.
right now you must think of the EMMC chip (its the name for the internal SD-CARD we boot from and store our normal data, imei and all the other data of the system, it is just a sc-card with better security for our purpose)
This emmc chip holds all of you settings for phone function and we must not loose that,
But...
we have to write data to the chip to boot again, I am not fully aware of all the memory locations so this is assumptions on my part.
we are going to write a basic bootloader that turns the whole phone into a sd-card, then write new bootloaders
using QPST we upload 8660_msimage.mbn (its a out of the box emmc factory image) this file is ment for setting up of dev versions of the phone, it made up of the following parts
sector 0 partition table or (partition0.bin AFTER patching with info from patch0.xml) I do not have a real copy of the original of this, it can be pulled from a working SVH-E160x using the code at the end.
after the MBR (which is the first part of the partiton make up, EBR follows, we can have 3 primary partitions and the fourth is a extended which is just another partiton table pointing to the next EBR and so on, upto 29 parititons i think)
anyway, after the MBR is SBL1, which chainloads SBL2 then that side loads RPM, gets a go signal then loads SBL3, when SBL3 is done most of the device hardware has been mapped into the cpu's memory table, SDRAM is now ready for larger code,
aboot now loads
some of the above loading functions occur at the same time and some wait on go signals from other code in other CPU's and some fail due corruption and or security check fails( JTAG users can watch the memory as it changes and halt, change data and continue which is why JTAGers's have more power , we dont have loader outputting data yet so no feed back, hence the brick)
when aboot is loaded we now have access to odin, so thats the goal, get aboot loaded for now who cares about the rest of the funtions.
we do need to care about those function later so thats why we will backup the entire system, i dont know if this will really work when restored and bring back all of our settings, thats later,
So onto the writing and possibly overwriting of important information, WARNING, i dont know yet if we are overwriting imei or simalr data yet so proceed at your own risk.
We will get the required from factory (qualcomm test or dev board not samsung factory in the box for consumer) from the MUI phone firmware
http://bigota.d.miui.com/QDN43/Mioneplus_QDN43_fastboot_Android_4.0_d3d83nmdk2.zip
from this zip we want 8660_msimage.mbn, patch0.xml, partition0.bin MPRG8660.hex ( this file is uploaded first, its a serial bootloader that is loaded at 0x2a000000 (start of PBL IRAM space 256k in size) and that setups a emmc to command access (we use revskill to upload the same file and dump memory , sadly ive not found a way of pulling the entire emmc to a backup, if we can figure that out we can pull the entire boot chain, fix it and send it back with what ever versions we desire, for now revskill is used to read the PBL error so we can at least see why we cant boot, not quite jtag but best we got ))
so now we have a phone running a basic bit of code that allows us to use code sent to serial port to write (possibly read) the emmc
we then use QPST to write the 8660_msimage.mbn as a one to one copy to the very start of the emmc , reboot phone and then when the phone restarts, it sets up the ram, some hardware (charging system, you will now notice your phone gets warmer that before when plugged in) and gives us direct access to the emmc as if it was a sd-card
at this point you could move the phone to any pc and it's just a sd-card branded qualcomm
BUT at this point the pc or any other computer you connect it too only see's the partition table contained in the 8660_msimage.mbn file , you other data is there so i advise the next step you MUST do.
connect the phone to a linux computer (use a live cd or live usb if you are not a normal linux user)
you will then run the following command
Code:
dd if=/dev/sd? of=/mount/location/shv-e160-full-emmc.bin bs=512
? is the letter of the drive , use dmesg and look for sdb or sdc , if you dont understand this part then i would suggest waiting for a possible script/one click solution. right now i am still booting only 1 in 20 boots and do not yet know why the boots fail and why some work.
of=/mount... this is where you will place the entire 16GB (32GB for 32gb models ) which should be a one to one copy of the system
the bs=512 is very important, it's block size, again, if you dont understand then maybe wait.
Thats enough for now, i am going to spend a hour or two working on some theories i came up with today.
user with working phones, please google how to backup parts of your phone, this may happen to you so it's best to backup asap !!!
from the blog.csd site a script to grab the partition table data, if a working usr could please run this and post the file, it does not contain user data only the partiton table and a direct 1 to 1 restore for any phone, i think it possible to write that direct back to a QDLoad mode phone, re write the bootloaders from linux and bingo working phone. i dont have backups as it's not my phone, it belongs to a client who knows i like to tinker with electronics.
anyway, once i have the partition file i can overlay it on my test phone (which i can activate QSLoad at any time, hence it's unbrick-able dev mode)
once the partition file is written to my phone, i can build a script to backup your important data, write known working bootloaders, and reboot the phone into a usable device.
here is the script in python (user linux live cd with a copy of adb, just google adb linux pack, there is a windows and linux allin one pack)
or you can get the original from the link above, i've not tested this as i dont have a device in adb mode but i've read through it and it looks sound but never tested by me.
Well i hope that enlightens you, am sorry i dont have a all in one solution for you, it's still a dev project and most of the information i have has only been collected over the past week, i only discovered it's QSDload after getting a msm8660 schematic and i still dont know what i am trully shorting out to trigger the QSDload when ever i want, even when it's booted
If any one from the unbrickable project(s) want to get in touch to share info i would be happy, i am also sure this is a usable solution for HTC phones as well
oh and one last thing
i read only a hour ago (via cell phone while in a car so not 100%) that once the phone is in QSDload and stays in QSDload on every power cycle then we can write the partition table to a SD-CARD and it will boot that, i have not tested that yet, i will try and see if the 8660_msimage.mbn file written to a sd-card works
I also suspect that some of my good boots have been when i've mixed up the sdcard with system.img.ext4 etc on it with the one with just update.zip on it. it's one my list of things to check , any suggestions are welcome as to how i correctly format the card (heads,cylinders, block size etc)
ok folks, hope this helps

thank you for your help,
I currently have the qpst version 2.7 build 373. You think is enough of download the same version of Chinese post QPST.2.7.374.rar
I will begin to download the other files required and I will be commenting my progress.
Thank you so much for your help, i really appreciate that you share you r knowledge.
Requests
While i try some theories if othe users could possibly provide me with :-
Original partition table via script above and also via adb
use
adb and run
Code:
cat /proc/partitions > /sdcard/partitions.txt
fdisk -l /dev/block/mmcblk0 > /sdcard/fdisklist.txt
mount > /sdcard/mountlist.txt
Then on the pc side using ADB again do the following
Code:
adb pull /sdcard/partitions.txt
adb pull /sdcard/fdisklist.txt
adb pull /sdcard/mountlist.txt
and post those files.
there are many posts on it so wont repeat but later will add a link.
along with some spell checks :laugh:
if you can dump the boot loaders from a original e160x too as my data started currupt.
i also need to talk to someone who can assist me in writing a program to take the pit file and turn it into this

*edit
the partiton0.bin provided below is 8.5kb (.5kb MBR, 8kb EBR) and in raw_program0.xml bove it say 0.5kb and 11kb, making that file 11.5kb, i dont know if the A810 has larger or smaller EBR than us, it could be they pulled extra, in my reading of the dumps i've seen lots of padded 0's after files (between sbl2/ebr/rpm) anyway if you just copy paste it will throw a error, ive got it set at 0.5 and 8.
EDIT:- Do not use this file, ive uploaded newer files later on.
some of the questions i need to answer are :-
1. what is the first partition, it's dos, around 105mb and labled smd_hdr and is filled with smd_hdr.bin (or mbn)
2. what are the real sector locations of the files, above you will see the rawpartiton0.xml file, this tells QPST where in the emmc to put the data num_partiton_sectors does match data from the pit files, but i dont know the real offsets yet, (samsung or htc could put the rest of the partiton table in cpu qfuse data areas and not write it to the emmc to confuse us and write the real files to another location and use the pit file as a base+offset calculation)
start_sector is the real location on the emmc, where it starts writing the file.
at the end is partiton locations(its a generic file containing the first few byes of default partition table, patch0.xml then updates this data), i dont have our device specific figures yet, i also dont fully understand patch0.xml and the difference in figures used.
if we have a backup of each of the different version of android partitons we could just write that in replacement of partiton0.bin and we dont need patch0.xml, this file sole job to alter the generic files, oem's have the choice of changing this data.

please note that it's two lines of the same code except one is partition0.bin and the other is DISK,
Do we need both? i know if i dont add the partiton0 section used in raw_program.xml then the drive is blank in linux,
now it's my understanding that the ebr comes as the forth partiton and it point to the next one , above in patch0.xml it start at NUM_DISK_SECTORS-1695744
i am still trying to better understand these figures,
Well time to grab coffee, i guess it's a dev night in.
the file MPRG8660.HEX can be renamed EMMCBLD.HEX and it triggers QPST to always look for a QDLoad mode phone and not debug, you can place all the files you need in one folder, i advise you to keep the originals in one location and only extract what your need to your worrking folder, copy emmcswdowload.exe from the QPST folder there too, we might need to do command line work, ive read that you can pre-create images in emmcswdownload (the same way 8660_msimage.mbn was created ) that you could just drop onto a phone once it's in emmc sd-card mode, almost a one click.
More info, plus help offered
Your welcome tyllerdurdent,
I am going to be putting a few hours into the dev from now actually for if you want assistance then no problems,
I also advise the following, download ubuntu live cd, it has a lot of tools your going to need to extract data you require, if we go step by step we might be good, i did a lot of test writing before i got my first boot, and that again only happens one in 20, i dont know why.
the rawpartiton0.xml above is incorrect for our devices as it states the first partion is 32mb, (i think it's ment to be amss.mbn, or NON-HLOS.mbn , our pit file which i did extract from my emmc dump says it's 105mb. i am confused and to why rawpartiton0.xml says the first bootloader is at start_sector="65537" but fdisk shows it as start 204801, i think someone needs to show me how to convert from blocks to sectors,
in patch0.xml it says
Code:
<patch byte_offset="506" filename="partition0.bin" physical_partition_number="0" size_in_bytes="4" start_sector="0" value="NUM_DISK_SECTORS-208801." what="Update MBR with the length of the EXT Partition."/>

208801 is where we have our ebr start,
i also think the IROM based pbl, sbl etc use the partition types in some way, why else have so many types? can any one explain that
this is a fdisk view of what i think our partition table looks like

Blocks and sectors
This may explain it , the different figure in the xml files
Because sectors are logical on the drive (Logical Block Addressing = LBA) you need to convert between LBA and physical (file system) sectors. This is pretty easy to do:
First - get a table of the start and end sectors of the partition table:
Code:
[[email protected] ~]# fdisk -lu /dev/hda
Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 63 208844 104391 83 Linux
/dev/hda2 208845 4401809 2096482+ 83 Linux
/dev/hda3 4401810 8482319 2040255 82 Linux swap
/dev/hda4 8482320 234436544 112977112+ 5 Extended
/dev/hda5 8482383 29447144 10482381 83 Linux
/dev/hda6 29447208 50411969 10482381 83 Linux
/dev/hda7 50412033 52516484 1052226 83 Linux
/dev/hda8 52516548 234436544 90959998+ 83 Linux
Use this to determine what partition the bad sector is in. In this case 232962120 is inside the start and end values for /dev/hda5
NOTE: This is in partition 5 - ignore partition 4 as it is the extended partition. Any block from partitions 5 through 8 will also be in partition 4, but you want the real partition, not the extended partition.
Next, calculate the file system block using the formula:
b = (int)((L-S)*512/B)
where:
b = File System block number B = File system block size in bytes (almost always is 4096) L = LBA of bad sector S = Starting sector of partition as shown by fdisk -lu and (int) denotes the integer part.
For example:
The reported sector from the smart log above is 232962120, thus:
((14858312 - 8482383) * 512) / 4096 = 796991.125
^Bad Sec. ^Start Sec. ^Cha Ching! This is the sector!
(Use the block number from the smart test section, not from the smart error log section. They are using different methods of reporting file system vs. physical blocks.)
((BadBLock - StartPartition) * 512) / 4096
You can just paste this into Google as a template
Any fraction left indicates the problem sector is in the mid or latter part of the block (which contains a number of sectors). Ignore the fraction and just use the integer.
Next, use debugfs to locate the inode and then file associated with that sector:

[[email protected]]# debugfs

debugfs: open /dev/hda5
debugfs: icheck 796991
Block Inode number
796991 <block not found>
debugfs: quit
Ah! It didn't give the inode! It if did, you could have found the file with:
[[email protected]]# debugfs
debugfs 1.35 (28-Feb-2004)
debugfs: open /dev/hda5
debugfs: icheck 796991
Block Inode number

Inode Pathname

So what the heck? Why no inode? Well, remember how it said the sector might be bad?

now i used this in a way to find my bootloaders (i717 by this time, not shve-160l )
and to find the partitons
you will see in a hex editor at the start of each boot loader
something else to think about, my lack of success that last two days to produce a boot could be because my partitons are not clean , thats is to say if i write my sbl1 to 1000, and the trailing 0000 of the partition definition of my 99 block ebr/mbr ends at 999 , if i have dirt data between 999 and 1000 the cpu/pbl my interpret that as code(some of my boots is brick, some are into QDLoad, i have no pattern yet) , something i must test or confirm, or just worry about.

25. recovery - partition to be used for recovery boots this is allinone image to let you boot when all door closed.
26. system - this is android which is booted once linux bootup and mounted at /system
33. cache - for temporary work usually lost after reboot but not always
43. userdata - this partition hold userdata, internal sd (/storage/sdcard0 or /sdcard), internal app installed mainly mounted at /data
10. tz
11. tzbak - Trusted Zone and back up are trusted zone providers to android
5. ssd - secure software download; "Secure Software Download" is a memory based file system (RAMFS) for secure storage, used to download and store "who knows what" on the eMMC. It is a referenced part in the Remote Storage RPC Client of the MSM kernel.
6. sbl1 - secondary bootloader
7. sbl1bak - secondary bootloader backup
8. rpm - resource and power manager @MotoJunkie01 /rpm is also known as primary bootloader, and flashing this partition should always be avoided if at all possible. /rpm, /sbl1, /tz, and /aboot are all considered bootloaders.

22. aboot - AP Bootloader {AP has some thing to do with APN configuration}
23. abootbak - AP Bootloader backup
20. fsg - Probably stands for File System (FS) "Golden". According to Samsung documentation, this partition is a "Golden Copy". This is partially confirmed by RE of the PARAM partition, which indicate that this partition should contain a copy of MODEMST1. As such it is a backup of the current EFS2 filesystem. The creation of a FSG is not supported on flash devices and the internal (QMI) DIAG request "EFS2_DIAG_MAKE_GOLDEN_COPY", can only be used to create a backup one time over the life of the device.

rest of the partition you write
Good research. /rpm is also known as primary bootloader, and flashing this partition should always be avoided if at all possible. /rpm, /sbl1, /tz, and /aboot are all considered bootloaders (and/or bootloader dependent partitions). Tampering with any of these is the quickest way to hard brick a device beyond repairability. /fsg, in Motorola devices anyway, is considered a radio firmware partition and contains the fsg-id configuration for carrier dependent parameters. I included /fsg in my modem thread (my baseband installer flashes /modem, /fsg, and formats modemst1 & modemst2). The /simlock partition does exactly what it implies. When a network unlock code is entered into the device, the requisite changes are applied to /simlock in order to enable GSM network unlocking. In theory, if an unlocked device's /simlock partition is flashed to a locked device, the locked device also becomes network unlocked. This works on most brands which use a similar partition index for network locking/unlocking. I'll research the partitions you didn't reference and add some additional info.
The /splash partition is the boot logo.
The /splash partition is the boot logo.
If you remove or tamper it you will get beautiful tux icon
Recovery and boot are actually in the same format -- an "ANDROID!" archive containing a kernel, an initrd, and a kernel command line. The recovery is just another kernel and an initrd containing all the files you see in your recovery.
Cache is used for the system communicating with the recovery. The system places a command in a file there telling the recovery to perform a function like factory reset or apply a FOTA. The recovery reads that, does the command, and writes its state and logs back to cache. I don't know what else cache is used for, but FOTA temp files certainly don't download there (they're in /data/data/com.tcl.dmclient/files/last_dlpkgfile on this phone), and the Play Store doesn't download stuff to there when installing apps.
tz/tzbak are something for the ARM Trust Zone, which is a bit like TPM on PCs. It's a function built into the processor that can be used to store keys securely. These partitions contain an ELF file, so I suspect this is a binary that interfaces with or runs inside the Trust Zone, and not the data store for it.
I haven't seen any real info about ssd, but given "Secure Software Download" and that it's only 8 KB, I'm guessing it's used by the baseband for things like updates and SIM apps pushed through the cell network.
The boot sequence as I understand it is rpm -> sbl1 -> aboot -> boot (Linux kernel).
Rpm, sbl1 and tz are updated with each firmware update for this device that I've seen. It looks like the updater changes rpm, sbl1 and tz; and then rpmbak, sbl1bak and tzbak are updated after a successful boot. The updater seems to update both aboot and abootbak though. I determined this by looking at a backup taken after an update and reboot, and one taken after an update and no reboot.
Do you have a link where I can read more about fsg, modemst1/2, EFS2 and EFS2_DIAG_MAKE_GOLDEN_COPY?

I can confirm that modemst1 and modemst2 are nv data partitions. The /fsg partition (a configuration which has been used by Samsung and Motorola for many years) is a baseband firmware partition that contains carrier ID and carrier regional information.

@Chupi383, Question: have you been able to successfully capture an OTA for this device? If so, where is the OTA stored once downloaded? Thanks for your help on this.
@MotoJunkie01 The downloaded OTA is stored as /data/data/com.tcl.dmclient/files/last_dlpkgfile.
You can also get the download URL for an XML file named "desc" from logcat. You can download desc by using a user agent string spoofer with the user agent "Red Bend Software vDirect Mobile(TM) RedBend-vdm-5.6.0.65". Then that will contain the download URL for the zip itself, which you can download with the same user agent. The fun thing about these zips is once you have the URL for one, you can guess the URLs for other to/from firmware version pairs.
History:
This was a virgin stock rom'd kindle that just didn't boot one day at the end of last November. The battery was showing signs of degradation, i.e. false/flaky battery life, and I think random restarts! My guess is that it was most likely updating when something went wrong.
I cannot be sure what firmware it was on or upgrading to, but at the same time that it happened, around the 22/10/2017, I could only manually download update-kindle-14.4.5.5_user_455004320.bin from amazon. But my daughters identical KFAPWI took the 4.5.5.3 update on the 17/10/2017.
So I'm going to take a stab, and say it most likely on 4.5.5.2.:fingers-crossed:
At one point I had the grey boot logo only, but after pressing too many combinations, getting drunk and falling asleep, it now does nothing:crying:. It does not connect to the pc at all, despite my persistence holding down the power button for far too long, and even using a factory cable - have got drivers previously installed from rooting/buggering/fixing another kindle, both standard and qbulk. Using a DVM meter on the battery yields the correct voltage for both cells too...
I'm better with the down and dirty hardware side of things, so I have taken the less-than-direct direct emmc access root by Ivan_nik in his post her on XDA: https://forum.xda-developers.com/kindle-fire-hdx/general/direct-emmc-access-t3249534 and have success in reading the EMMC.
I now have a full EMMC image, along with individual partition dumps done with DD in Hiren's partition magic Linux, hooray! So in my mind I can do whatever I like, and I should be able to restore from any mess that I make.
But WTF to do now?? Reading through the many posts here, there's talk of flashing partition images from the stock firmware, .mbn and .img etc. Some of them 'seem' easily mapped to partitions:
rpm.mbn > rpm
sbl1.mbn > sbl1
sdi.mbn > dbi
tz.mbn > tz
emmc_appsboot.mbn > aboot??
from this folder within the unpacked firmware:

But if you unpack the fwupdate.tar, there seem to be duplicates:

And which boot image to dd to which boot partition?:

I found this reference in the install-recovery.sh, and one of the references below match the boot.img above:
"#!/system/bin/sh

else
log -t recovery "Recovery image already installed"
fi"
Linux is not my strong point, Me being a mainly M$ based IT tech, but I'm a quick learner - if only I can stop my eyes from going curly.
Any tips, pointers or even a bit of humour at this point would be greatly appreciated.
Thanks for reading.
Ok, I have confirmed that at least in part, it was 4.5.5.3. Comparing what partitions I could discover here on XDA to the ones found in the stock image.bin using HxD, some of the following are identical in all but file size, due to trailing zeros in the backed up img files:
01.modem.img same as 4.5.5.3 NON-HLOS.bin
02.sbl1.img same as 4.5.5.3 sbl1.mbn
03.dbi.img same as 4.5.5.3 sdi.mbn
04.DDR.img
05.misc.img empty - all zeros
06.aboot.img same as 4.5.5.3 emmc_appsboot.mbn
07.rpm.img same as 4.5.5.3 rpm.mbn
08.boot.img same as 4.5.5.3 boot.img
09.tz.img same as 4.5.5.3 tz.mbn
10.pad.img empty - all zeros
11.modemst1.img
12.modemst2.img
13.fsg.img empty - all zeros
14.fsc.img empty - all zeros
15.ssd.img empty - all zeros
16.dkernel.img
17.dfs.img
18.recovery.img same as 4.5.5.3 boot.img patched with recovery-resource.dat
19.persist.img
20.persistbackup.img
21.cache.img
22.system.img
23.userdata.img
Partitions 17, 19, 20, 21, 22, & 23 are all ext4, and mount easily in parted magic. Build.prop in system states that it is 4.5.5.3.
That leaves very little partitions with info on them that I don't know how to compare/check, 4, 11, 12, & 16.
And are partitions 5, 10, 13, 14, & 15 normally empty?
Hello! help please help with Amazon Kindle Fire hdx 8.9 OUR CITY DOES NOT INCLUDED AND THERE ARE NO MASTERS WHO COULD MAKE IT HAVE A FRIENDLY MASTER HE HAS A PROGRAMMER SAYS IF THERE WOULD BE a dump then he would help fix other things but he says he could if someone gave a direction! Thank you
