Hi 2 All!
Please, can you help me in solving with the following problem.
I have download file bootloader.exe to my hp ipaq 1930 and I run it.
Now I see hp logo on white font and some numbers (bootloader version?) 1.07 and under it 1.07
Certainly, hard reset and removing the battery for 2-3 days didn't help. As I was said I need only to run update from big pc. I have another 1930, alive. I made rom-image to sd card using mtyy
Flashing with the card with rom-image didn't help to my injuried 1930
I contacted hp and they said to me that
the rom version for hp1940 1.00.03 is compatible. Then I ran the update, before that changing in the *.nbf file 1940 to 1930 and started flashing. It went to 75% and stoped saying Update error.
Then I was said to fullfill sd card with one symbol (Z). Then I made again a rom-image and I copied all hex values above code Z into a new file. I founf 2 entering starting from FE 03 00 EA and deleted the values above. Then I copied from 1940 nbf the following information^
Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F
00000000 68 70 20 69 50 41 51 20 68 31 39 34 30 00 00 31 hp iPAQ h1940..1
00000010 2E 31 30 2E 32 30 20 45 4E 47 00 00 00 00 0F F6 .10.20 ENG.....?
00000020 71 77 00 00 0C 01
and in the dress from E1-21 wrote checksum value in 32 bit and length of the file in the addresses from 22-25. Then I copied the file into the folder from 1940 with the name=the name of the *.nbf file in the folder. I started update. It began and stoped on 50% saying "Update eroor"
Are there any ideas? Thanks a lot.
Or perhaps somebody has firmware for 1930/35? Thanks a lot
Maybe these people could help you, they must have the image if they are offering the service.

Thanks. Here is the *.nbf file for 1930. http://www.megaupload.com/?d=HROH0ZOO It must have the same nema, as it is in the folder, where 1940 utiilty unpack it's files.
Copy it where the 1940 romupdateutility unpacked it's files. Then run again the utility

Hello everyone.
With the development of the New ROM, I decided to describe this and that.
-How to Prepare files and packages.
-How to create stable SYS and OEM.
-XIP Porting (Kernel) - if it succeeds.
-Build/Mod. BLDR/BOOT Section
-Change PagePool
-Etc
Small introduction:

Everything described here are doing at your own risk.
I do not answer with any damage to the device.
Please read carefully and proceed with caution.
Topic applies only Toshiba devices Tsunagi: TG01
Execute Image System:
This step tutorial will be further developed.
Once, I'll add this feature in my kitchen.
Add OEM Apps:
OEM - This package is derived from the *. cab file.
It must include:
- The *. dsm guid the value of the name,
- The *. RGU with the same value in the name, it must be in Unicode encoding.
It must also be free, the last line in the content of the text.
- Application *. exe, *. dll, or library
- A shortcut to the program / library - if it is needed. It is not mandatory.
- Content may be more developed (in the files / programs)
Such a package can be easily added to the root of the OEM.
If, of course, is properly filed
Dependence of the Application, the memory devices.:
How can you distinguish the memory which will hit your application / library?
This differs from the rule:
- Module - that is, a file that looks like a directory goes to RAM.
- File - normal-looking, *. exe or *. dll file, going to Storage memory
Porting XIP (Kernel) and insert this file to Image System:
[TUT][UTIL]Remote Porting XIP
Working good in my kitchen for Toshiba TG01
XPR to LZX Compression:
Open the file os.nb.payload in HEX Editor. Find this Lines:

Save this file. Get this library -> cecompr_nt.dll, then insert to TOOLS folder from your Kitchen ROM.
Download cecompr.dll and overwrite it in your XIP. Build XIP, build ROM, see results. Now Image System takes less memory.

Thanks for Camelio
good idea, may be i'll try to understand something and build an italian version too, even if we are quit lucky with our tg01 'cause it's no brand at all.
Thanks for your great job with developement
Hey Nokser do you create wm6.1 rom for tg01?
Nokserze can you writa Polish version too?
here or in pdaclub forum, but I wont to understand anything, so it's more simple in our's language
Thanks for your job
Yes, of course
When you will to make this tourial? or you can write the tourial for stabil oem's now I want to make a rom but i can't create a stabil oem or a oem that's works... or you can tell me how i must put the oem.
Greats ALcAtRas
I give all my work in this, but first I must port WM6.5.5
Nokser, could we use the information you have gained about our device to port android?
Wm first, then we'll see Android

I ran the following command while ssh'ed into my Atrix 4G and do not understand why it contains only ff's or 00's for entire partition (no executable code)???

Questions:
/dev/block/mmcblk0p1 is the bootloader partition?
If so, why does it appear to not have any executable code?
Is dd being tricked in some way and NOT actually getting the content of partition 1?
If so, is there anyway to dd the actual content of partition 1?
Somewhat off topic but related questions:
Assuming the bootloader is signed where is the PKI public key/Digital Certificate/Digital Signature/hashing algorithm stored on the phone? How are they protected?
Is there a pre-bootloader that checks the Digital Signature of the bootloader partition? If so, where is the pre-bootloader located? How is it protected from tampering?
Regards, Ron
Is the bootloader available via busybox dd from the phone?
I sure would like to examine/backup the content of the Motorola Atrix 4g delivered bootloader code. Is there any way of getting a copy of it from the phone using DD (or any other method from a rooted/NOT unlocked phone)?? I thought at least part of the bootloader was in partition 1 of the on board EMMC NAND flash /dev/block/mmcblk0p1?? It appears the bootloader code is either NOT in partition 1 or DD is NOT allowed to access the code. I am basically trying to understand what happens in the VERY first stages of the boot process after power on (in detail).
Signed Confused, Ron
PS, I assume some of the developers (with great knowledge) views this forum from time to time?
Hi
I just changed some stuff like images in a kernel using Android Kernel Kitchen 0.3.1.
Now I wanna test my changes.
My questions is->
What are worst case scenarios possible?
I am ready to go for boot loops and etc. but are there any consequences that may cause real hard brick of my phone? (Like---> it will never start again! or you need to take it to service center for repair!)?

What you can expect are boot loops, inability to get even see the boot splash, non-working wifi/ USB / touch / camera/ anything that needs a driver, random reboots. Personal experience: yesterday I was playing with changing part of the initramfs without changing the whole boot.img. It turns out that I needed to update the header size and checksum. Without this, it would hang for some seconds and then reboot (or not start at all). This was all fixable from recovery.
What can happen if you are not careful is a brick because you flash the wrong partition. Otherwise, you can always enter recovery mode and flash the kernel (for the i9300, it is mmcblk0p5). If you are not sure, look for the magic ANDROID! header:
Code:
# dd bs=64 count=1 if=/dev/block/mmcblk0p5 2>/dev/null | hexdump -C
00000000 41 4e 44 52 4f 49 44 21 80 bc 44 00 00 80 00 40 |[email protected]|
00000010 2e 1e 05 00 00 00 00 41 00 00 00 00 00 00 f0 40 |[email protected]|

00000040
So, the absolute worst-case scenario is when you accidentally flash the wrong partition. If you picked your EFS partition and do not have a backup, then your IMEI and stuff are gone.
Note: be sure not to wipe your recovery partition (mmcblk0p6), that requires you restore the recovery using download mode (I have not experienced this yet).

Kk, thanks.
But what do i do if it does not start at all like u said (what i want is that it should at least be able start in recovery or download if possible).
Since its my first time messing with kernel, i am total n00b then
If it cannot proceed to the "normal" boot, then get into recovery by holding Volume Up + Power + Home for ten seconds while booting (I usually do that when I see the Samsung logo end release when it has restarted, showing the logo again (about ten seconds).
From there, use Install from zip (if you have a "update zip" that contains boot.img and some metadata) or (what I do) use adb push to put the image in /tmp/. Then use dd to write the boot image. Example (I use Linux):
Code:
laptop$ adb push boot-new.img /tmp/boot.img
laptop$ adb shell
# cat /tmp/boot.img > /dev/block/mmcblk0p5
Just in case of hardware failure, I also verify the md5sum:
Code:
laptop$ md5sum boot-new.img
laptop$ du -b boot-new.img # determine file size, say 1234
(android) # dd if=/dev/block/mmcblk0p5 bs=1234 count=1 | md5sum
The two outputs must match, otherwise something went wrong (unlikely, but still).

I know all this but what i m saying is that can there be conditions where neither i will be able to boot recovery nor download (even by volume+power+home method)?
Unless you do really stupid things like overwriting /dev/block/mmcblk0 or other partitions on http://cleanimport.xda/index.php?threads/2362743/, you will be safe.

Recovery has it's own kernel. It doesn't use the one you're modifying

Scroll down for recent updates;
Has anyone ever heard more from h311sdr0id about his post (see here) to get more info about this "state" that allows you to flash MDK over ME7 in Odin? I'm curious to see if we can use that state, maybe in QDL mode to somehow either push an image to the phone or communicate with it using some methods/commands that E:V:A refers to on this page and a few pages after and before. It's also possible that we then might be able to use a modified unbrick.img (see here) to restore an MDK bootloader. So far those are the two ideas that I think have the best chance.
Also in this thread I started with the intention of compiling the entire stock firmware for the Dev edition (OYUAMDK), I mentioned at the bottom that when flashing the stock MDK restore Odin tar on an ME7 phone users usually get a "SW REV. CHECK FAIL: FUSED: 3, Binary: 1" message meaning that your current fuse counter in aboot is set to 3 but the binary your attempting to flash is set to 1 so the flashing attempt will fail and I'm willing to bet if you're on VRUDMI1 and you attempt to flash the MDK restore you will get a similar message but the FUSED: value will be set to 4, you can see the counter upped in this post from jeboo here. However, with flashing the dev OYUAMDK aboot file on S4's with a ME7 bootloader users will receive a "SECURE CHECK FAIL: aboot" message instead, I don't know if we might be able to use dev OYUAMDK aboot file and bypass the fused counter entirely, since the dev edition has an unlocked bootloader and the fuse is an efuse, so software enforced, not a hardware enforced qfuse. If anyone wants to go into more detail, or wants to expand on these ideas we I can expand on this info or we can collaborate ideas in the Dev discussion thread.
Other points to consider:
If you know how to use IDA pro, and can help with the base address of the binaries, that is probably our best bet to find a vulnerability in aboot, you can see jeboo and djrbliss discuss this a bit (here) and you can see Ralekdev show his findings here, also this gives the explanation of why you see the "custom unlock" boot screen that people constantly post about in the Q&A thread. Both of these threads along with djrbliss' blog discussing the S4 aboot vulnerability that lead to Loki (here), and exploiting the TrustZone (tz.mbn) on Moto's bootloaders (here) are good starting points in trying to find a new vulnerability.
If you know how to hexedit, then hexedit aboot.mbn from MDK, ME7, OYUAMDK, and MI1. You can see ME7 and MI1 are similar in both size and content, while MDK and OYUAMDK are more similar to each other in size and content. Obviously OYUAMDK differs from the others in the way it checks the recovery and boot partitions, (in djrbliss' blog on the S4 exploit he says "This bootloader differs between "locked" and "unlocked" variants of the Galaxy S4 in its enforcement of signature checks on the boot and recovery partitions.") but we are able to flash all bootloader partitions from the OYUAMDK firmware restore Odin file I made except aboot, so if you have any ideas on how we might be able to exploit any of that, please feel free to share.
If you do hexedit a dd'ed partition (if you copy mmcblk0p6 from your phone to your pc) you will see that its padded with zeroes at the end. You have to cut the padded zeros from the dd'ed image in order for the partition to be registered as a signed partition in Odin, etc. To do this, use Linux, open a terminal and type
Code:
sudo apt-get install hexedit
then enter your password and hit enter. Then go to the folder that contains the partitions you want to hexedit (for instance type cd /home/Your user name folder/Desktop/S4partitionbackups/" where "your user name folder" is whatever your username is and "S4partitionbackups" is a folder you create on your desktop containing a backup of your partitions) If you don't have a back up of your partitions you can create them using something like the command below, substituting mmcblk0p6 and aboot.mbn with the partition(s) you are interested in.
Code:
adb shell su -c 'dd if=/dev/block/mmcblk0p6 of=/sdcard/backup/aboot.mbn'
then
Code:
adb pull /sdcard/backup/aboot.mbn /home/Your user name folder/Desktop/S4partitionbackups/
then
Code:
cd /home/Your user name folder/Desktop/S4partitionbackups/
Code:
hexedit aboot.mbn

How to find start addresses
First you have to open the selected bootloader with a hex file editor and look at the header, converting for little endian you can find the start addresses and offsets
Code:

EDIT: 2/01/2014 - Updated OP to include where we're at
2/01/2014
1. Figuring out what Hellsdroid's method was - Unfortunately this seems unlikely as of now (figuring out what he did that is) On the other hand, @TMcGrath50 and I discussed a method we thought to be similar to his starting around here and then I learned how to use ida better as time went on and recently disassembled that I9505 S4 USB repair tool. I have not done a thorough analysis of the pseudocode yet though. But even so, this method has never been done before (as far as I know) and
in addition to assuming the information in the pic below is true, and we can in fact reset the emmc on our devices with Secure Boot 3.0 (would this be a way of getting around having to reset the Secure Boot bit in the pbl to "0"?) I still think this idea needs to be refined a bit before its worth exploring because some questions remain in regards to if it would even work in the first place. For example, when a JTAG solution was tested previously, the VRUAMDK aboot.mbn didn't flash on a device with VRUAME7 after all the partitions were wrote over with VRUAMDK partitions via JTAG, why? @jeboo may be able to help answer that.
Also, it was previously questioned whether or not the flash programmer (8064 hex) would need to be signed or not. As I have two S4's one thats working and one in QDL QHSUSB dload mode, in doing some recent testing through usb (S4 to S4) I was able to get some info back about my bricked S4, namely that I had sent it the wrong hex file ( see the last line here) because the dmesg and last_kmsg logs say something to the effect of "the the cpu clocks cannot start because its configured for the wrong device" and the last line from the my pastebin post says "8660" among other things as well.

2. Using a Developer edition S4 to unlock a retail S4 - So here's what we know, the dev kernel (boot.img) is flashable and will work with retail S4's, but the recovery.img and aboot will not. Flashing the dev recovery.img will succeed in Odin/Heimdall, but if you try to boot into recovery it will inform you that your device is "tampered" and and will void your warranty by setting the Knox warranty bit to 0x1. Before I discuss why aboot.mbn wont flash consider this; neither the Developer edition of the GS4 nor the Developer edition of the Note 3 has every received an OTA or a factory Odin tar. This is not by random chance. Every Developer edition owner has a unique MD5 for their aboot. If you couple this with the fact that Dev edition devices have retail stickers under their dev stickers, you will probably come to the conclusion that Samsung/Verizon/AT&T haven't released updates to dev devices because they would have to do it on a 'per device' basis, that or risk handing us a method to convert retail devices into developer edition devices. If the method by which Samsung uses device specific info to sign developer edition aboot partitions were discovered this may work, or if their method to determine if a device is a developer edition or consumer retail edition is similar to what Dan R (djrbliss) took advantage of then this could be a possibility.

This really sucks. Looks like the dev that knows how to downgrade from ME7 to MDK is locked up for a while.
h311sdr0id is currently indisposed and will probably not be getting out anytime soon. He has court next month. If anyone is interested in writing him, please send a message to his account and I will give you his info.

WOW, this is news to me! It explains why I haven't seen him update his VS3 rom in awhile.
@Nicgraner
Sarcastic joke, or are you serious?
I noticed in the note 3 part of the forum a member started a petition to unlock the boot loader. Can someone start one or combine with the note 3 page?
Petitions just turn into complaint threads. I wanted to give this a last shot, so I posted alot of info and plenty of references with the intent that even less experienced s4 users could learn and eventually contribute to helping unlock this bootloader. I also offered some ideas as a starting point. Ive never joined irc's or google talk sessions with others in trying to solve things, I mostly read and learned on my own and im by no means a dev. But I don't think we can unlock this unless we stop complaining and one-uping each other and start working together. I wish that people would stop asking if devs are still trying to unlock this, or being pessimistic about it and start being part of the solution by reading a little and then helping contribute to a solution. All suggestions are welcome. But if you don't know what comprises the "bootloader", learning the flashing order of the partitions at least uptil tz.mbn would benefit you greatly.
P.S.
Just because your not a dev doesn't mean you cant help, most devs are knowledgeable about their devices, but some don't know much beyond how to use android kitchen.

On that note, I thank you for developing the OYUAMDK FW. I have not tried it yet just waiting for another guinea pig or at least have a backup device to swap SIMs so that I can have something to use.
Samsung has their first Dev Conference today in San Francisco and hopefully there will be Devs there to get better insight on Samsungs position on ROMs and bootloaders etc...
Awesome analysis Surge, that hellsdroid thread piqued the interest of several devs, including myself. Unfortunately I believe his thread was a bit misleading, which may explain why he closed it. There has been no demonstrated method to boot vulnerable BLs (ie, loki-fiable aboot) once the qfuse has been incremented.
Some of us are looking at the binaries, but no exploit has popped out yet. I did find it interesting they updated SBL1 in the latest OTA, that may be a hint towards something..

So I just started analyzing my emmc back up (took the entire 16gb mmcblk0 to make sure I didnt miss anything) have you looked through the emmc? I think the modem and apnhlos are more involved in the security checks than we previously thought. Plus these tima, tzapps, and apps.mbn etc files may have contributed to the failure of flashing the mdk aboot on the me7 device you guys were attempting, is there a reason you guys didnt include the mdk modem and apnhlos in your attempt to restore the mdk bootchain? I flashed the dev bootloader with the exception of the dev aboot, boot and recovery using 3 heimdall packages. The first contained the modem, apnhlos and sbl1-3. The second contained rpm and tz, and the third contained boot and recovery (as expected this package failed) the result was my device was now on the dev bootchain with the exception of aboot, boot and recovery and confirmed these results via hexedit. So I think we can rule out sbl3 being the main culprit in checking the fuses when trying to flash a new aboot, also I dont get the "fused 3 binary 1 aboot" failure message when I attempt to flash aboot anymore, just the "secure check fail aboot" message. I definitely think its worth looking into using the dev tz.mbn to find an exploit because I no longer ever see the "samsung custom unlock" boot screen and my device believes its unmodified, and reports its official. My device is so far from unmodified its ridiculous. That means the dev tz.mbn partition I flashed is behaving as if my s4 is a dev edition (see ralekdev's post I linked to in the OP)

So does this mean if I flash your OUYAMDK ODIN image my Dev Ed phone will think its OOB without custom unlock?
Theres a post in that thread where a dev owner achieved those results as well he only flashed a couple partitions, you can get more details there

I've always known Samsung to be like Google when it comes to consumer development. Google supports and encourages the freedom to modify Android, it being open source in the first place. Samsung doesnt mind, themselves; it's carrier security teams that require companies like Samsung to create their own methods of locking down the device for the average user. I'm quite impressed with the Knox bootloader and secure VM app. It may not be done anytime soon, but it can always be cracked. But, the fact that this code is so hard to modify, thanks to carriers, is actually a good thing.
Hey guys I am totally supporting this thread. Unfortunately i have no experience in this kinda stuff or else i would help. Good luck!
Much like most of us. Still out there Surge?

Still here I use tw based roms so my motivation for wanting to unlock this isnt for AOSP or custom kernels. Its just the challenge, that and out of hate for Verizon lol. The Droid X sitting on my desk is a painful reminder of defeat. Cant let them win twice..

No doubt... can't believe i left my G-Nex for this locked down thing... unfortunately i had to craigslist an upgrade and couldn't snag one of these when they first came out.
i am also in full support of this thread! running stock MJ7 never rooted my phone once, i have taken all the OTAs i'm really crossing my fingers that someone can break this thing so i can finally root and install a stock google rom, i hate TW so much! with all the headache with safestrap and junk on the MI1 i was not wanting to root my device just to have a half assed recovery.
Does it mean anything that my S4 is still showing unlocked and custom? Should it still show that even if it is in fact locked?
