TF700T complete flash layout

I spent some time in analyzing of flash layout. The comprehensive description below attempts to map each byte of the flash and describes way to extract it.
I would be glad if somebody could provide more detailed info about bootloader, signatures, DRM etc.
Patches are welcome.

Read commands are ran on the Transformer
Extract and process commands are run anywhere, with pre-read image file in the current directory.
You need dd with large files support. Vanilla dd on TF700T does not support large files. Busybox dd does.

Wow, thanks for this detailed analysis - much more detailed than mine.
So what can I add to your research?
Tegra-based systems have another partition table, which has a proprietary layout and an unknown purpose (maybe just important for NVFlash and for flashing blobs?). Looking at the flash.cfg in the NVFlash package from AndroidRoot.mobi, we can get the Tegra partition layout and partition names:
Partition number 1 is missing in the list, maybe it contains the extremely well-hidden APX mode recovery code or even the answer to life, the universe and everything.
The following 3 partitions are located at the beginning of mmcblk0 and their contents are apparently encrypted with a device-specific key. For some reason, with ICS-based ROMs it reads as all zeros; in JB-based ROMs additional mmcblk0boot0 and mmcblk0boot1 partitions appear which together cover this area. The "bricksafe.img" in the nvflash guide covers these 3 partitions.
2 BCT: Tegra Boot Configuration Table - 3145728 bytes
3 PT: Tegra Partition Table - 524288 bytes
4 EBT: Bootloader - 8388608 bytes
You already know the following 2:
5 SOS: Recovery kernel - 8388608 bytes
6 LNX: Linux kernel - 8388608 bytes
Then some more funny ones:
7 CER: I think this stands for "Certificate" and contains the bootloader unlock token. - 8388608 bytes. If I calculated correctly, this is at 0x1380000 into mmcblk0. Saved as "unlock-token.img" in the nvflash guide.
8 IMG: no idea what this is for - 8388608 bytes
9 GP1: space for a GPT partition table, maybe unused - 1048576 bytes
Now the regular partitions follow (p1 to p8):
10 APP: p1 = /system (Android OS)
11 CAC: p2 = /cache (for communication between Android and recovery)
12 MSC: p3 ="misc", whatever that is. On the TF101 it was used for bootloader commands.
13 USP: p4 = The update staging partition. Update blobs are copied here and flashed to the correct partition by the bootloader.
14 PER: p5 = device-specific config in a FAT filesystem
15 YTU: p6 = Apparently the DRM key. Confirmed to be overwritten with 0 by the unlocking process.
16 CRA: p7 = unknown (reserved for crash dumps?)
17 UDA: p8 = /data (Android user data)
And finally:
18 GPT: the EFI partition table that is actually used by the kernel

Well, it seems, that something (ICS stock kernel, hardware) hides contents of the first (at most) 0x380000 bytes of flash.
I am locked, and I have some token at 0x1380000 as well.
I am still thinking about a way to unlock, keep access to nvflash, and upgrade to JB keeping DRM working, even at cost of using stock system. That is why I wanted to backup and analyze everything and find all keys and signatures.
It would be also nice to know, whether there are areas of flash with hardware or kernel write lock.

Yes, before unlocking I had something very similar to you there - a 16 byte header followed by some hexdump. I don't know what it was. It was overwritten by the unlock process with a 4 byte data block prefixed with a "-SIGNED-BY-SIGNBLOB-" header and followed by 256 bytes of what looks like a digital signature, very similar to the signed update blobs.

Definitely back up the YTU partition before unlocking (p6) and then make the nvflash backups - but maybe the key must match something that is broken by the unlocking process, or it is renewed periodically, etc., so it might not help. Maybe try using DRM before unlocking and watch if the content of the partition changes over time.

Never tried to write directly to the block device - too scared to break something.

Another small addition:
Note: /data/media is mounted via UID/GID stripping FUSE as /mnt/sdcard

This FUSE trick also makes /mnt/sdcard case-insensitive.

I just thought of something. What if you launched a data recovery process and recovered the DRM keys for the device?

How do you define "data recovery process"? You cannot recover data that has been overwritten.

Well, if the DRM partition is write enabled, it may be possible to restore its contents, if you backed it up before unlock (it is probably per-device unique). But it could be insufficient. Locked bootloader can be different than unlocked bootloader, and may drop cipher needed for DRM decihering. It is just a theory. Somebody could proof it or falsify, if:
1) Backed all accessible data before unlock.
2) Unlocked (and to be safe, also made brickproof image).
3) Recovered the data creates in step 1.
Will DRM work then? Or did we need the contents of (currently inaccessible) locked stock data of the first megabytes?
But I see no way, how to back-up first megabytes of locked device (on ICS; JB is not as interesting for us, once you upgrade to JB, you cannot create brickproof image for nvflash).
I even don't know, which part of the subsystem causes these megabytes being reported as zeroes. Is it stock Asus ICS kernel? Is it bootloader? Is it a hardware lock on the flash device?

Good idea, but what I meant by "Data Recovey". Is restoring the deleted data from that filesystem/partition.

I see, so I assume you assume you had a backup before.
Somebody (maybe you?) could try roughly the following sequence:
- get new TF700
- update to 9.4.5.26. if it's already newer, forget nvflash, but the rest could still work.
- root it using debugfs
- make a backup of /dev/block/mmcblk0p6
- do some DRM-dependent stuff and check that it works
- after some days, make another backup of /dev/block/mmcblk0p6 and compare if anything has changed. If the key is static, maybe restoring after unlocking could work. If not, chances are high that it doesn't work.
- unlock (this erases mmcblk06 and voids warranty)
- optional, but very useful: install AndroidRoot hacked bootloader to make blobs for nvflash, then use nvflash to backup all partitions
- restore backup of /dev/block/mmcblk0p6
- try if DRM still works

To install AndroidRoot bootloader and by that getting nvflash blobs, you have to unlock first... The order of your steps is therefore wrong.

Oops, thanks for noticing. I edited my post.

what if we were to read from the NAND externally (RAW)....xbox 360 style...wouldn't that be the same as nvflash....
except that the three partitions in question are encrypted with a key that is probably unique per Tegra...
2 BCT: Tegra Boot Configuration Table - 3145728 bytes
3 PT: Tegra Partition Table - 524288 bytes
4 EBT: Bootloader - 8388608 bytes
but I would suppose it wouldn't be a problem since a raw flash would restore everything back to normal...even if we can't read it..the CPU can..and that's all that matters.

Correct order maybe.
- get new TF700
- update to 9.4.5.26.
- root it using debugfs
- make a backup of /dev/block/*.*
- unlock (this erases mmcblk06 and voids warranty)

Q1:If i backed up 9.4.5.26 all block image.After i updated 9.4.5.30 can i get the nvflash blob from backed up images?No way to dig out the blob key from the backup?

No way - the BCT, bootloader, etc. is not visible to the kernel at all (so it's not included in your images), and I don't know which kind of magic the blob creation tool uses, but I assume it's more than reading stuff from the nand.

[GUIDE][Xiaomi Mi-One] Changing size of /system partitions

Disclaimer: I am not responsible for bricked devices, dead SD cards, thermonuclear war, or anything else. YOU doing this at your own risk.
This guide is taken from 4pda.ru forums and tested on my own device.
I strongly recommend you to make Nandroid backup with CWM Recovery v6.0.3.0 so after repartitioning ALL DATA (/system, /system1, /data, /cache) WILL BE ERASED.
1. Connect you phone to PC via USB. (USB debugging must be turned on)
2. Install MiFlash. Remember installation path. It will install drivers for "Android Composite ADB Device". If there's still one "Android" device without drivers - just ignore.
3. Run Command Prompt (cmd) and go to the %FOLDER_WHERE_YOU_INSTALLED_MIFLASH%\Google\Android (For me it was C:\Program Files (x86)\Xiaomi\MiPhone\Google\Android)
4. Type adb devices and press enter. It should start adb daemon and show your device with status offline. Check phone for dialog and allow USB debug from your computer.
5. Type adb devices again. Now it should show your phone with status device. Close Command Prompt.
6. Download and unpack to any folder attached archive tadb.zip
7. Run tadb shell.bat. If everything fine it will show something like "[email protected]:/ $"
9. Type su and press enter. If requested allow root access on phone.
10. Now enter busybox fdisk /dev/block/mmcblk0 to start repartiotioning program (All changes are virtual until written)
11. Delete all partitions from 20 to 15 inclusive. For this enter d, enter 20, enter d, enter 19 till 15th partition.
After this enter p. Your partition table must be like this
Code:
Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 1 12801 102400 c Win95 FAT32 (LBA)
Partition 1 does not end on cylinder boundary
/dev/block/mmcblk0p2 * 12801 12863 500 4d Unknown
Partition 2 does not end on cylinder boundary
/dev/block/mmcblk0p3 12863 13051 1500 51 Unknown

/dev/block/mmcblk0p14 20481 20864 3072 58 Unknown
12. Recreate needed partitions table. Press n, enter start block, end block. You can use attached partitions.xls to calculate needed values. Also You can change size of system partitions in this file as you wish (Make them 384Mb for example). Values will be recalculated.
13. Now we must return System type for 17th block (recovery). Enter t, enter 17, enter 60. After this operation your partiotion table will be like this (If you left 256Mb):
Code:
Device Boot Start End Blocks Id System

14. Time to save changes. If you not sure, you can just enter q to leave without saving changes. Enter w to write new partition table. Program will show error about using old partition table - that's normal. After you reboot phone - changes will be applied, so it will not load anything except fastboot.
15. Load phone in fastboot mode (Power + Volume Down + Mi-Button), go to folder with tadb and run flash_recovery.bat. It will flash CWM 6.0.3.0 to your device.
16. Go to mounts & storage menu and format /cache, /system, /system1 and /data
17. Now you can restore your nandroid backup.

What is the point to do all these? Are some benefits from this change?

Some custom ROMS (MoKee OS for example) have very few free space in /system after installation. Not enough even to flash GApps.

Yes, I know about that but there is already a tool for repartition. I thought that this was more than that. It' s nice that you can customise the size though. But isn't dangerous? I'm saying this because I've hard break my device twice using gparted. I had a full linux backup of device though so I recovered it but was the only way to do it. I succeed once though.

What's the name of the repartition tool? I'm caught in a wicked cloning loop that duplicates my partitions periodically and I haven't tracked down the cause. Ota JB Feb. 1st is the day it started. Thanks

As for Forumber' s modified way to larger /system, search on U8800 developing section, it' s in a lot roms threads.

just a note:
On M1S phones the last END block is 477184 and not 488448 like M1+ and M1 C1
all is equal except that
So M1S users take in mind when repartitioning your phones.

Well, when creating last partition (/data) you can just hit Enter when prompted for last END block to use Default value. I think tadb automatically will use 477184 instead of 488448 for M1S. Not sure.

i dont know if this its related but here it seems that there are a easier method to change the size
the author have it set on 280mb but it could be increased

yes, is my tutorial for an automated way to do the changes from a recovery instalable .zip
just download, flash a compatible recovery (any cwm with busybox for M1/S should work) then install the zip for ur phone model.

Partition Layout
streetdev22 said:
Recently rooted and unlocked the bootloader on my Huawei Prism II, but there is no custom recovery nor custom roms for this phone. I have tried determing the partition layout in order to dump the recovery, but I am unable to do so.
Tried earlier versions of romdump, but they returned with a segmentation failure.

I believe I've found the partition layout based on the /etc/recovery_mmc.fstab extracted from mmcblk0p13, but am not sure. The excerpt of my /etc/recovery_mmc.fstab file from mmcblk0p13 shows some partition names correlated to device names. Could someone verify this is a legitimate way to determine the partition layout? I've also attached the whole recovery_mmc.fstab file.
recovery_mmc.fstab excerpt:
Code:

Very nice!
Correlates with the hints found in other files as seen above, so I think we have successfully found the partition layout! I will take a look when my device gets here(originally was working on my relative's phone, but now I purchased it for myself). If this method is confirmed,we can to port CWM, thank you all!! After CWM, we should be able to make custom ROMs freely.

First, I made a selective backup using a google store app called Online Nandroid Backup https://play.google.com/store/apps/details?id=com.h3r3t1c.onnandbup&hl=en to make a backup on the "recovery" partition. Even though the app does not specify which block it copies, I believe the app makes a backup of /dev/block/mmcblk0p13 because it uses /system/partlayout4nandroid to determine the partition layout. If you look at the "cat /system/partlayout4nandroid" output below, you'll see that mmcblk0p13 corresponds to recovery.
Then I transferred the recovery.img from the sdcard to my computer.
From there, I followed the directions in Step 1 and Step 2 of http://www.imajeenyus.com/computer/20130301_android_tablet/android/unpack_repack_recovery_image.html to unpack and extract recovery.img.

Probably correct.
My father(the owner of the phone) has once again left on a trip, so I will have to wait until Monday/Tuesday, when I receive my phone, to confirm these results.
My only issue with this is is why nandroid shows a different partition layout then what is shown in other files.
If partition 13 is recovery, there is no coincidence that you would find that fstab file in the extracted recovery.
Do you mind dumping all the extracted files from the recovery and uploading them to 4shared, mediafire, or any other cloud service as a compressed file(zip, tar)? I think the file is not coincidental, and that we have indeed found the partition layout(or at least the important partitions for our purposes).
Also, try dumping the boot partition that is currently identified (block 12) without using online nandroid backup(I think via dd should still work) and see if you can find similar files to that explained in the guide(.png, ramdisk directory, etc). If these files match up to what would be typically found in a boot.img or recovery.img, then the layout is most likely correct.
If these files match up to typical boot.img or recovery.img files, we can test the layout by changing something simple like a background before working on serious stuff.
Also, thanks for helping! Once we conclusively identify that this partition layout is correct, we can start to port clockworkmod.

The extracted files in partition 13 can be found in post #44 of http://forum.xda-developers.com/showthread.php?t=2546455&page=5 labeled as "ramdisk.tar.bz2". I will make a dump of the boot partition using dd and run the tests tomorrow.

Looks validated, Also more tools
There are other guides on the matter of porting cyanogenmod..for example
http://wiki.cyanogenmod.org/w/Doc:_porting_intro
which even mentions a recovery.fstab file in recovery.img! So, that means the partition layout in the fstab file you found is most likely correct.
Another guide:
http://xda-university.com/as-a-developer/porting-clockworkmod-recovery-to-a-new-device
Also, there is an automated tool to porting cyanogenmod for new devices..
http://builder.clockworkmod.com/ (I would recommend avoiding the touch recovery for now, simple is all we need and we don't need more complications)
I am really feeling pretty confident about the partition layout found in the recovery.fstab, because one guide mentions it to be found in the recovery.img!
I would recommend making the changes to a recovery.img instead, because boot.img is still kinda scary (possible bricking )
Also, I think there is a command to try booting from a recovery.img without flashing the .img to the actual partition.
I think the command is mentioned here: http://forum.xda-developers.com/showthread.php?t=2233477
fastboot boot recovery.img is the command and it will not overwrite your existing recovery.
By using this command, you can try booting the stock recovery you extracted(to validate that we have a stock recovery available if we need it), and then boot the recovery.img you make with small edits, and then boot the recovery.img made from the automated CWM porter.
Thank you for replying so fast! We have made real progress in the last few days.
Edit:In the ramdisk that was extracted, another fstab exists on the root of the directory that is named fstab.msm7627, which is the same name from the file I located in post 1! They are the same file! I think this is validated.

a test recovery.img that is the same in every way to the original recovery.img except that all the images under /res/images is rotated 90 degrees. You can see the difference yourself by looking in res.rar attached below.
a clockworkmod recovery image from the clockworkmod recovery builder website
These images can be found attached below:
recovery.rar = original Huawei recovery image
recovery-test.rar = edited recovery image
recovery.img = clockworkmod recovery automatic builder image from http://jenkins.cyanogenmod.com/job/recovery/52069/
Unfortunately, I cannot test this image myself, because I do not want to unlock my bootloader yet.
If anyone with a rooted, unlocked Huawei Prism 2 is interested in helping to further the development of recovery roms for the Prism 2, I have made 3 tests to see if
the recovery partition is located in /dev/block/mmcblk0p13
the command "fastboot boot recovery.img", which we will be using extensively, can be used to boot the specified image file
the Clockworkmod Recovery image made from automated CWM porter successfully boots
The files you will need are provided below. I've also given instructions to the best of my ability without actually having done this.
To test if the recovery partition is located in /dev/block/mmcblk0p13:
Go into fastboot mode (step 2f in post #1 of http://forum.xda-developers.com/showthread.php?t=2546455)
Download the recovery.rar file below and extract it to get recovery.img.
Open up terminal
change directory to where you extracted recovery.img
type
Code:
fastboot boot recovery.img
See if phone boot into recovery
Next we test an edited recovery.img to see if "fastboot boot recovery.img" is truly letting us boot the image we've specified.
To find out, we're going to use the edited recovery.img and do pretty much the same thing except now with recovery-test.img:
Go into fastboot mode (step 2f in post #1 of http://forum.xda-developers.com/showthread.php?t=2546455)
Download the recovery-test.rar file below and extract it to get recovery-test.img.
Open up terminal
change directory to where you extracted recovery-test.img
type
Code:
fastboot boot recovery-test.img
See if any pictures are upside down (the battery symbol, numbers, or the android robot)
After completing the 2 tasks above, and verifying that we have a valid original recovery.img and that we can use
Code:
fastboot boot recovery.img
to boot a specific image file, we can start testing a very, very, very EXPERIMENTAL Clockworkmod Recovery image using fastboot. I would not rely on this image to make backups and I honestly do not know what kind of damage it might inflict on the phone so make a backup of everything before starting.
output from CWM automatic recovery builder: http://jenkins.cyanogenmod.com/job/recovery/52069/
To test if this CWM recovery image will boot and have the right partition layout:
Go into fastboot mode (step 2f in post #1 of http://forum.xda-developers.com/showthread.php?t=2546455)
Download the recovery.img.
Open up terminal
change directory to where you downloaded recovery.img
type
Code:
fastboot boot recovery.img
If the cwm recovery image boots, type
Code:
mount
See if /sdcard is mounted to the right partition)
If you're feeling lucky, make a backup to /sdcard **this step can cause damage to phone if /sdcard is mounted to the wrong partition**
Thanks for volunteering and bringing the Huawei Prism 2 one step closer to custom roms.

Will test as soon as I get the phone.
I should be getting my phone in the mail Tuesday-Wednesday, but I will test as soon as I get it in the mail and I get my bootloader unlocked. I shouldn't have an issue booting it, since it will boot without effecting my current recovery partition. Hopefully the cwm recovery boots as well.

Great! I really hope it works. Let me know if I can help with anything in the meantime.

Getting my phone today
My phone is coming today! I will let you know the results either later today or tomorrow. Also, could you pull a build.prop using ADB from your phone? This guy needs it: http://forum.xda-developers.com/showthread.php?p=49494728

niceeeee

Thats good news! Could you state specifically which 2 of the 3 images booted though? I'm assuming the original (recovery.rar file) and the edited (recovery-test.rar file) recovery.images, but want to make sure
In other words, did you test the clockworkmod recovery image?

first two

I did just boot the clockworkmod recovery and i just booted up fine. os is running as it should other than the whole missing settings app. im stuck without root, without wifi, and usb debugging.
adb not installing the app either so idk.

Thanks for straightening out the confusion. Can you check the mounted partitions are correct? Afterwards you can use update.zip to install your settings.apk

Never mind about checking the partition layout. I just remembered you don't have adb. I will try to make a better recovery image.

ZP980 unbrick/study of partition table

Hi to all, I hope to be posting in the right section...otherwise...punish me plz
It's a long story, so i hope that someone has time and want to put some effort to help me understand what i'm doing wrong.
By the way i work in IT field and have some knowledge about linux (let's say 5 on 10) but not so many on how android really works, but i'm confortable with custom recovery and roms, i'm still using an s4 mini (GT-I9195) with mine android 9 custom rom and i'm super happy with it.
Now that presentation are done , here is the matter.
I've found an old zp980 32GB (NOT the "plus one") that some years ago i've rooted it flashed with recovery and custom rom. all was working, but at some point i started playing with fdisk and parted and i messed up things.
Honestly i don't remember what exactly i was doing, but now the status of the phone is:
System not booting
I can enter into Recovery (custom TWRP by dezmen3 v2.4.4.0)
I can connect to adb into recovery
I cannot flash rom trough recovery due the actual system partition (589 MB)
I cannot flash the original rom trough SP flash tool due "SFT enable dram failed (4032)" error
The partitions actually are (what i can see from recovery):
System (589 MB)
Data (54MB)
Boot (6 MB)
Recovery (6MB)
Cache (4 MB)
uboot(0 MB)
nvram (5 MB)
Free space: 27412 MB
Actually, I've tried to reformat the memory using SP flah tool, but i got the same error "SFT enable dram failed (4032)", all drivers are ok, i can see COM port in deivce manager tried win 10 and even win 7.
SP tool ver. used v5 1720 more updated version tells me that the brick i'm tringo to flash in not supported anymore xD
Here a dump of fdisk -ul /dev/block/mmcblk0 from adb shell
Bash:
Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 1024 1022 2147483647+ 5 Extended

Partition 2 does not end on cylinder boundary

/dev/block/mmcblk0p6 4869120 1022 2145049599+ 83 Linux
if i make a print from parted (pushed with adb) I get:
Error: Can't have a partition outside the disk!
Before i was also having an error saying that there was an extended partition into a logical one (don't ask me how I do it), but i removed it
So, now....what to to to rescue this device?
by the way honestly except for the instinct of "recover things that doesn't work" my main purpose is understand:
What I've messed on the partitions
Why sp flash tool can't reformat/flash the memory (i haven't tried to manually modify it again)

no brave person hat want to help me to brick it in a bad way?
EDIT NEW INFO
i've understtod that the problem was caused by
/dev/block/mmcblk0p1
and
/dev/block/mmcblk0p6
start and end were inverted , them were overflowing.
Now i used fdisk to remove part 1 (the extended), so i've lost also 5 and 6 (system and cache) and i have recreated them using 1 GB for each and using correct sector order.
now SD and try to flash a ....random compatible rom....see u later for info.
Cross your finger for me xD

flash failed it cant mount system and emmc.....
and now
~ # cat /etc/fstab
/cache ext4 rw
/data ext4 rw
/emmc vfat rw
/system ext4 rw
/sdcard vfat rw
/sd-ext auto rw

if someone has a zp980/c2 working can please post me the result of
cat /etc/fstab
from adb shell??
and a fdisk -ul?

Need a repartitioning expert to restore an omitted partition

I think I did some mistakes while trying to reflash a rom on my Sony Xperia S (lt26i).

My problem is that I deleted my OS and TWRP can't read the data partition nor mount to Windows.
So now, with djibe89's help (the OP of the guide), I managed to figure out that my data partition is corrupted.
Using the adb shell, like on step 12 of the guide, I went to the partitions and it gave me this

The partition 14 should be the data one, that i already merged with the 15 the first time i flashed the rom.
What should I do?

try deleting it and let Android generate new one??

Code:
fastboot erase userdata
fastboot format:ext4 userdata
fastboot reboot
now there's a high chance that your device doesn't support " fastboot format:ext4 userdata "
here's an alternative
fastboot erase userdata <~ never reboot your device after typing this command you would go on infinite bootloop type the next command ...
fastboot reboot recovery <~ if this command does not work and just restarted your device instead of going recovery mode you are now on bootloop ... access recovery mode by pressing combination key instead
via recovery mode do "wipe data / factory reset"
then reboot

the first method didn't work because of the format command like you predicted.
then i did the <erase userdata> but i think the <reboot recovery> command isn't available because it returns me the commands list. so i used this command from the list
fastboot reboot-bootloader

then unplugged the usb and rebooted on twrp.
now my data partition went back to 0mb (going to wipe -> advanced wipe -> data -> repair or change file system) and i can't even reformat it.
should i re-do the adb procedure to recreate the data partition?

yes your device won't boot without userdata partition since it got deleted with "fastboot erase userdata" so you need to recreate it by "formatting" it somehow

so i wanted to "recreate" the data partition with adb but now i can't even use adb.
i went to mount on twrp with the phone connected and the cmd still running from 2 hours ago. when I type adb devices I can't find
... is it possible that i did some irreversible mistake?

you have TWRP flashed? you can't use it to format data?
also looking at the Sony Xperia S (lt26i) specification it was released back in February 2012 i guess it has serve its purpose for too long it is time for it to retire
