-----------Final Notes--------------
It has been mentioned many times that i should go back and correct the information below, i started to correct a few post's then realized i was removing the flavour in change of colour and size, parts of this thread documents my mistakes, assumptions and general lack of understanding of how we NOOBS post on XDA, It's with that in mind that i have decided to leave the mistakes in, so you can see in writing what i gained from the support of other Devs here.

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
Taken from gsm-forums:-

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:
------------------------------------------------------------------
BC[5:0] Mapping
------------------------------------------------------------------
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)
Click to expand...
Click to collapse
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
41032 /S1/R/H/714197568-714203359/H-R-714202192-16.gwf
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.

I'm working on my first ROM that is based on the "stock" Samsung firmware. I am used to messing around with AOSP and CM ROMs where there's a nice flashable ZIP with a boot.img in it. Working from the "stock" Samsung image has been less clean.
My device is a Samsung SGH-T869 (the T-Mobile version of the Galaxy Tab 7.0 Plus).
I began with the file T869TMBLG7_T869UVLG7_T869UVLG7_HOME.tar.md5, which is the newest firmware available for this device.
I am able to extract the image using 7-zip, which gives me the error "There is no correct record at the end of archive", but otherwise appears to extract perfectly.
Extracted files include:
-boot.bin
-cache.img
-factoryfs.img
-hidden.img
-modem.bin
-param.lfs
-recovery.img
-Sbl.bin
-zImage
These files are enough to give Android Kitchen something to start with, but AK is complaining about the lack of a boot.img, plus I want to do some ramdisk tweaking. I have been researching this for hours, and I get the impression that what I need is in there, just in a proprietary format. I have installed KernelKitchen, which I guess I can use to build boot.img from zImage and a ramdisk, I'm just not sure where to go from here.
I also tried dumping ADB (dd if=/dev/block/mmcblk0pX of=/sdcard/boot.img, tried all partitions one by one).
I also looked at a backup made via CWM 6 of the 'stock' untouched ROM running on my tab. My backup contains:
-boot.img
-cache.ext4.dup
-data.ext4.dup
-nandroid.md5
-recovery.img
-system.ext4.dup
So far, no success. The various imgs I have pulled are all treated as invalid by Android Kitchen and also split_bootimg.pl by William Enck. When running that nice Perl script I get the error "Android Magic not found".
My general first goal is a cleaned up stock ROM which has been deodexed, zipaligned, with insecure boot enabled, and of course, root.I would like to also do a sweet custom boot image and boot animation, but I believe its best to start with a solid foundation before jumping into the other stuff. Any suggestions, XDA gang? Somewhere in that mix did I get the actual boot.img but Samsung uses a weird header? Or something else?

Your first instruction (to "rename and unzip") makes no difference at all.
The second suggestion seems like it may be useful.
From the CM9 flash script I found that /dev/block/mmcblk0p5 is the boot partition.
I am not sure what's wrong with the boot.img I am pulling.
Here's my command session:
Code:
adb shell
su
dd if=dev/block/mmcblk0p5 of=/mnt/sdcard/boot.img

adb pull /mnt/sdcard/boot.img
I attached the resulting file. I looked at it a bit in a hex editor but I'm not sure what I'm lookin for...

It seems that you managed to extract a kernel image (zImage). What you are looking for is an image starting with the signature "ANDROID!".
What do you see if you enter the following command?
Code:
$ cat /proc/mtd
It should read something similar to:
Code:
dev: size erasesize name
mtd0: xxxxxxxx xxxxxxxx "system"
...

You are probably going to have to trim some extra data off the front of your boot.img so that the tool finds the needed Hex address. If you haven't already I'd pull the applicable scripts out of dsixda's kitchen and see how he handles it.

I'm pretty sure you're after the partitions. However, there's no /proc/mtd on the SGH-T869 running stock.
Code:
[email protected]:/proc # cat partitions
cat partitions
major minor #blocks name
179 0 15388672 mmcblk0
179 1 20480 mmcblk0p1
179 2 1280 mmcblk0p2
179 3 1280 mmcblk0p3
179 4 8192 mmcblk0p4
179 5 8192 mmcblk0p5
179 6 8192 mmcblk0p6
179 7 204800 mmcblk0p7

259 4 8192 mmcblk0p12
179 8 30318592 mmcblk1
179 9 30317568 mmcblk1p1
When looking at /proc/mounts, I see that partitions 1, 4, 7, 9, and 10 are all mounted. I'm also relatively certain that mmcblk1 is the microSD card slot, based on its size (I've got a 32GB card installed at the moment).
So, ruling those out, we're left with:
Code:
major minor #blocks name
179 2 1280 mmcblk0p2
179 3 1280 mmcblk0p3
179 5 8192 mmcblk0p5

259 0 16384 mmcblk0p8
259 3 524288 mmcblk0p11
259 4 8192 mmcblk0p12
I have already extracted the first 8 partitions and tried running each through Android Kitchen's boot.img unpack tool without success. The script fails to locate the ANDROID header within any of the files. I'm guessing Samsung uses some sort of custom header, because if it works perfectly fine, why not mess with it?
I've searched through a few of the files with XVI32 for "ANDROID" but didn't get any hits.
As posted earlier, other ROMs flash boot.img to mmcblk0p5 so I'm pretty sure that's the right space.
Any hints on an application I can use to analyze the dump and locate the offsets where the header and ramdisk are inside it?
Update. In my research I have come across this article:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
It wasn't directly helpful but it did give me a key idea: "Find the Magic Number for a GZ archive and you'll find the ramdisk inside the raw image"
As per http://www.garykessler.net/library/file_sigs.html, the "Magic Number" for a GZ archive is 1F 8B 08. The first article only mentions "look for a bunch of zeros and then 1F 8B." That never occurs in my dumped file, and the number 1F 8B occurs 65 times. However, "1F 8B 08" only occurs once in the entire file, indicating the spot where the header and kernel end and the ramdisk begins.
I deleted everything before 1F 8B 08 and saved the result as ramdisk.gz.
Then, I threw the resulting file onto one of my Linux boxes and used the following commands to extract:
Code:
mkdir ramdisk
cd ramdisk
gunzip < ../ramdisk.gz | cpio -i --make-directories
ls
(results of ls command here:)
data init.goldfish.rc lpm.rc ueventd.goldfish.rc
default.prop init.rc proc ueventd.rc
dev init.smdk4210.rc sbin ueventd.smdk4210.rc
fota.rc init.smdk4210.usb.rc sys vendor
init lib system
I did this stuff in a command terminal connected over Putty, and I got a ton of crazy output during extraction, mostly the line "cpio: Malformed number" over and over.
My next planned task is to take 3 boot.img dumps from my tablet and them compare MD5s on all 3 dumps, to ensure I got a "good" copy.
I imagine this is largely unnecessary, but I've learned from working on other embedded devices that you can't be too careful about raw reads / writes.
I'm pretty sure now that I have extracted the ramdisk I am OK. The factory firmware has zImage as a discrete file, so I'm pretty sure I can use either Android Kitchen or Kernel Kitchen to repack the stuff into a "normal" boot.img.
I'll post my results here, since there may be like one other person interested in doing ROMs for the T869
Just a little update, the md5sums on ALL of my various dumps matched.
By that I mean CWM's backup and all the various dumps I did via ADB (using the dd command) all match.
md5sum for this firmware's boot.img appears to be 1e4367954524901c7dfff14b02023163
Interesting and a great research!
I look forward to see more of your progressive work.

According to RFC1952, the gzip header only contains two bytes (ID1, ID2), while the third byte (CM) normally seems to be set to 0x08 (deflate) - so you did the right thing to include the third byte.

Hell yeah, I'm surprised at how much I've achieved, since today has been pretty busy at work. I use Putty, WinSCP, and SplashTop to access my home machines from the office, and I've got an ADB command line connection to my tab on my workstation here, so I've been able to get a lot done.
My current task is reverse-engineering dsixda's scripts that do the task of taking apart the boot.img. I should have looked at them before, they're well-written and self-documented. It's looking like I'll have to figure out the weird offsets Samsung is using (already half done) and then I can tweak the scripts so they'll probably be able to unpack / repack the image.
If I'm building a stock ROM do the offsets and header have to all be the same on my modified boot.img? I would assume so, but I'm new to this
I only want to modify the ramdisk a bit, no kernel tweaks.

After much searching, it looks Samsung's boot.imgs sometimes simply have no header at all, so like the first chunk is the kernel, and the second is the ramdisk. I'm gonna test out unpacking ramdisk, making the changes I need, repacking it, and then combining the two chunks back together for flashing.
Will post results

I took a new look at your boot.img today.
Besides the gzip header at address 0000:4634 (which you found), I also noticed that there are 256 (0x100) bytes at 007f:fc00.
Any clue about this?

Feel free to use my updater-script in the scorched kernel thread. The updater works for ics boot images. just remove the parts about copying lib files and setting permissions ... and remove the lib files from the zip. they are specific to the kernel. a stock kernel will break if those lib files are copied to /system/lib/modules.
Oh, and you can get the boot image easily in CWM by doing a backup of the stock rom and grabbing it from the clockworkmod folder on the sdcard.

As posted earlier in this thread, I pulled a boot.img from a CWM backup, but that was back before I knew how to do anything useful with it yet.
The md5sum of the CWM-generated backup boot.img matches the dumps I did over ADB using the dd command, so they're different ways to get the same end result. I have a pretty good understanding of the syntax used in the CWM flashable ZIPs. My rough plan was to first build a "restore to stock boot.img" flashable zip (so I can fix it if I make my tab unbootable ), then experiment with building my own boot.img and flashing it using the same methods. The only thing that'll be different about the "flash modded boot.img" and "flash stock boot.img" is the actual boot.img file included in the zip. Didn't get a chance to do it while off work last night, but should be able to knock it out today.

Your guess is probably better than mine, honestly. I would think that second address is actually within the 'ramdisk' part of things, so that seems pretty odd. I'm a relative noob when it comes to hex stuff, as that's a couple levels down from where I usually operate with computers
If I unpack, modify, and repack the ramdisk, any suggestions on the 'best' way to reattach the header/kernel to it?

Following up on this earlier point, it looks like there are a few more regions within the 8 MB file than I initially saw.
I use XVI32, so the addresses I found are formatting as such.
it seems like the following is the layout of the file contents:
Part 1 - $000000 to $004633 = 17.5 KB header?
Part 2 - $004634 to $4768A6 = 4.44 MB ramdisk (?)
Part 3 - $4768A7 to $7FFBFF = 3.53 MB of zero padding
Part 4 - $7FFC00 to $7FFCFF = 241 bytes footer
Part 5 - $7FFD00 to $7FFFFF = 768 bytes of zero padding
My initial attempt to unpack / repack the image of course made the device unbootable. My "restore" flashable zip worked as expected, so I'm now able to mess around with this stuff with relative ease.
I'm still getting a bunch of weird crap in my terminal when extracting the ramdisk. The command I am running is gunzip -c ../ramdisk.gz | cpio -i run within the directory where I want the files to extract. Both under Cygwin in Windows and under Ubuntu Server, I get tons of "cpio: Malformed number" followed by garbage. Under Ubuntu Server, despite this weird output, the files actually DO appear to extract and I get 1.65 MB of unpacked files, all in the expected format and directory structure.
Under Cygwin it didn't extract at all.
I'll continue to mess around but for your hacky fun, I have attached the parts all split up and then packed into a single ZIP.
Post if you have any ideas. I'm gonna try and repack the ramdisk and then re-assemble the whole thing. The repacked ramdisk will be smaller, but I'll just fill in the empty spot with zero padding so that the footer still ends up at the same address. We'll see if that works
Quite interesting result so far...
I wonder if there are some documentation on the data structure of the footer information floating around in public, and secondly if the offset is static.
Speaking of padding zeros. Maybe the number of trailing zeroes depends on the payload size and the page size (evenly divided by given page size), which is the case for e. g. boot.img?

It will take some experimentation to see how picky the boot loader is. I have been sidetracked today by actual work (imagine that!) and also I have been working on exhaustively cataloging and documenting the contents of the stock ROM, particularly /system/app. Cutting the Samsung bloat has been challenging only in that there's so much stuff to remove
I just had a brainstorm: I'm going to examine the boot.img from the CM9 and CM10 ROMs for the T869. After all, both of them are accepted by the bootloader, so those two and the "stock" boot.img must share some common properties, which one would think would be the "key" stuff to make the boot.img work.
The boot.imgs from CM9 and CM10 both lack any useful "handles" to try and understand their contents.
I'm uncertain how else to proceed.
I have tried creating a modified ramdisk archive, then padding out the rest of the space with zeros so that the various pieces of boot.img fall at the same location, but no success.
I'm beginning to think everything about the Samsung boot.img is weird. I was able to locate the boot logo, but its located in the ramdisk at /sbin/fota.png.
I've been knocking away on this for like a week now, and I'm beginning to think maybe it ain't worth it. All this so I can get insecure boot and maybe a modified boot image? Freakin Samsung
I am looking to compile a new kernel for this device. I have pulled off the boot.img file from /dev/block/nandc and used split_bootimg.pl to pull apart the kernel and the boot ramdisk. I have used extract-ikconfig to get the kernel config and built my new 3.4 kernel (with modules). So far so good...
I have tried to build the new boot.img file with no avail. My concern is with the original kernel as the new one should be build the same (I think). It looks like it is not compressed as I run the command
file boot.img-kernel
It returns
boot.img-kernel: data
So it is not a Linux kernel ARM boot executable zImage
Is this correct? Can Android boot with this or is the split_bootimg.pl tool not creating the file correctly (it does pull the ramdisk as I have uncompressed it fine! and the file does contain the kernel config)
Ok So assuming I can create a proper boot.img with my built zImage and the old ramdisk, what do I need to do with the modules? Do I update the boot.img on the tablet and copy the modules over to the existing /system/lib/modules? (this appears to not work)
I did not find an exact guide on android kernel and the modules....

Ok so the mkimage command can be used to pull the uImage out of the Kernel Part of the file like this:
mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux 3.0.8" -d uImage boot.img-kernel2
The only question is where in the boot process can I find the "Load Address" and "Entry Point" values that are required to create my uImage. I would think that these are going to be needed as options when I build my new kernel, and I will need to change the boot process or add a boot.scr file with my options. I have mounted the /dev/block/nanda partition (uBoot partition) but am not certain on where I would find the current environment values.
I did find this little snippet on the net that referes to the base address for this device xxx.tabletroms.com/forums/all-other-android-tablets-general-discussion/5791-full-specs-whatever-else-polaroid-pmid10c-tablet-2.htmlx
mkbootimg --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz --cmdline 'console=ttyS0,115200 rw init=/init loglevel=8' --board sun4i --base 0x40000000 -o boot.img
But he never discusses where he found the -base address. Is this the same as the Load Address and Entry Point?

Ok so the mkimage command can be used to pull the uImage out of the Kernel Part of the file like this:
mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux 3.0.8" -d uImage boot.img-kernel2
The only question is where in the boot process can I find the "Load Address" and "Entry Point" values that are required to create my uImage. I would think that these are going to be needed as options when I build my new kernel, and I will need to change the boot process or add a boot.scr file with my options. I have mounted the /dev/block/nanda partition (uBoot partition) but am not certain on where I would find the current environment values.
I did find this little snippet on the net that referes to the base address for this device xxx.tabletroms.com/forums/all-other-android-tablets-general-discussion/5791-full-specs-whatever-else-polaroid-pmid10c-tablet-2.htmlx
mkbootimg --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz --cmdline 'console=ttyS0,115200 rw init=/init loglevel=8' --board sun4i --base 0x40000000 -o boot.img

So the base address is found in script.bin (converted to text file with bin2fex tool). This is the information found in it:
[dram_para]
dram_baseaddr = 0x40000000
Still how do I find the "Load Address" and "Entry Point" for the current kernel...

Well more reading leads me to use unmkbootimg but on my linux 32bit system all I get is:
# strace ./unmkbootimg
execve("./unmkbootimg", ["./unmkbootimg"], [/* 20 vars */]) = 0
--- SIGILL (Illegal instruction) @ 0 (0) ---
+++ killed by SIGILL +++
Illegal instruction
Too bad I can see the souce code to find out what this program is doing or compile it for myself.....
split_bootimg.pl should give you the parameters i listed on tabletroms.
What source are you using? Polaroid never coughed any up and i last harassed them in February.

I am using the linux--sunxi kernel for now with an additional patch for dmard06.ko (which I do not expect to work!) I emailed them for the kernel source but just received a form email saying they will get back to me..... oh well I will as again.
Just playing around for now to see if a newer kernel will tweek up the speed on this device as it is very laggy.

I may be using an older version of split_bootimg.pl?
On another note, I was able to execute unmkbootimg on a different linux server. I was attempting to run it on a PIII 800 so it needs something > a pentium (I guess).

think the parameters you're searching for are specific for building the new kernel without proper source code to extract them from?
maybe you could get them from dmesg while the tablet is running?
else think there might be a way to grep the variable names in the existing kernel binary or headers?
i also would like a fresh kernel.
maybe useful stuff here:

i haven't checked this out yet, but may be useful.
Well I have build a new kernel and copied the modules over, but I does not boot. It appears that it never mounts the ramdisk as it never gets to the second splash screen, but I am flying blind as there is no serial port to debug with. I suspect that I do not quite understand the boot process for this tablet.... here is what is on the nanda vfat partition: (good information here http://rhombus-tech.net/allwinner_a10/a10_boot_process/)
since this is in my linux.ini
cat linux.ini
[segment]
img_name = c:\linux\u-boot.bin
img_size = 0x80000
img_base = 0x4A000000
[script_info]
script_base = 0x43000000
script_size = 0x10000
[logo_info]
logo_name = c:\linux\linux.bmp
logo_show = 1
Not quite certain how to setup img_base on my compile I guess.
I have tried the linix.ini from the link above but the tablet booted to livesuite image... that is a fail.
Not being a kernel developer.... I am wondering if the option to setup SUNXI_NAND_COMPAT_DEV is creating /dev/block/nandX or /dev/nandX as this will definatly impact the init.sun4i.rc file as it is mounting /dev/block/nandX This could be my first issue.... but then does /init first display the initlogo.rle or start processing init.sun4i.rc. Well if the first thing it does in load initlogo.rle then I am not even getting this far....below is the description of SUNXI_NAND_COMPAT_DEV
Symbol: SUNXI_NAND_COMPAT_DEV [=y] │
│ Type : boolean │
│ Prompt: Create old nand device names (nanda-nandz) │
│ Defined at drivers/block/Kconfig:564 │
│ Depends on: BLK_DEV [=y] && SUNXI_NAND [=y] │
│ Location: │

well a little more reading leads me to this page on the CarbonRom http://www.slatedroid.com/topic/64378-rom-carbonrom-422/ turns out that if you want to run a 3.4 kernel you MUST update u-boot (http://www.mediafire...4ro667xcfkd2dv7).... so I have flashed the CarbonRom and it does boot with the u-boot update. Not to worry the new u-boot will still boot the old kernel. The only issue I have with the CarbonRom kernel is the missing dmard06 driver so no touch screen..... I may get a new kernel working yet!

the patch compiles,you need to comment out #include <linux/earlysuspend.h> as it is not supported on the newer kernel and not required by the driver anyway. I just need to get the kernel to actually load lol..... I have at least gotten past the boot screen now, but it hangs.... I will try a different arm tool chain and see what happens next.....
So close but yet so far..... well I have the new kernel installed and booted with adb shell available but it turns out the new mma7660.ko is not compatable with my device I get this error from dmesg over and over and over....
<4>[ 3254.934675] incomplete xfer (0x20)
<3>[ 3254.938093] Assertion failed! drivers/hwmon/mma7660.c,196,mma7660_read_xyz,result>=0
Will rename the driver and see if I can get past init further in the boot....
Edit
Well more issues with drivers the dmard06 is not compatible either, I had more success with the Carbon Kernel I will see if I can find the source git, should be around....
dmesg | busybox grep dmard

This all makes some sense as Polaroid has not get gotten me the kernel and the drivers they load (their kernel have very unique names:

I suspect after all the trouble I had with LG source that there are device-specific bits in the drivers.
Polaroid will most likely have to cough up source to get it all working.
Have you considered trying punchmod to use the old drivers? I dunno if that'd work considering the stock kernel is a lower version... but it might be worth a try.

I have changed the vermagic on the old modules and tried with the newer kernel but no go.... the latest 3.0 sunxi kernel is at 3.0.96 so I will build this one and see if I can get the special 3.0.8 polaroid modules to load.
I have a ticket open with Polaroid lol I guess we will see if the cough up a kernel or not.... I would not put money on it...

Do you believe that something like this http://gpl-violations.org/faq/violation-faq.html could force them to provide the source code? I could try to get the group at "FreakTab" to make the same requests for the kernel sources. Maybe with enough requests the gpl-violations group could take it on?
(K I am getting off topic here sorry anyone out there......)
I have attempted to build the 3.0.96 kernel but it did not boot.... back to hacking at the .config to see what I have missed (I need to move my build environment off this old p3 800 lol)
