[GUIDE] Backup of your BCT AND Partition with NVFLASH on the gtab

** UPDATED WITH .BCT saving, include USB as well as NVFLASH just copy in
** 1 dir, run the batch and keep those you may need them one day
** Read the batch file for more info
It is clear for me is that it is not a perfect solution to use nvflash with images that you do not know the source.
The tegra S.O.C. use the information from a file stored in partition#2 to configure some low level setting like flash memory chip speed, total memory installed, video memory installed, flash type etc. As an example, if for some reason a batch of tablet is built with more memory then the .bct files will need to be changed accordingly
It is already confirmed that there's at least 2 different type of hardware. (2 different images by bekit do not use the same .bct configuration)
When flashing after a full wipe after using the create command, nvflash read the .bct configuration files and store it in the partition #2 on the tablet, bct files are created by the manufacturer using a tool from nvdia called buildbct. They are not writen during regular nvflash (where the partition are not re-created)
This also mean it is MUCH safer to NOT replace the partition 2 when nvflashing a device... (the hardware configuration would not be touched).
This batch files will work under windows and will not modify your tablet in anyway
please make sure you use the nvflash tools that is 151K there's an older and smaller one in some package, it will output binary inside the partition.txt instead of plain text. The version 2 include everything you need to backup the device under windows
Thanks to the various poster of thread about nvflash for the correct command THEY did the hard work not me !
To Restore individual partition the command is
"nvflash.exe" --bl bootloader.bin --download X partX.img
where X is the partition number you wish to flash, as stated you can also use your backup from clockwork mod for partition 11 restore.
this will not work for partition below 4
P.S.
I am not trying to start a debate on the validity of the current recovery (thumb-up to the guy who offered those!) They are valid for MOST device however
if you do have a different device this will alleviate any issue that may happen with nvflash restore.
see 2 post below for full restore info

Hi,
I know that the partitiontable shows a partition named "BCT", but is there also something else, perhaps flashed into the SOC itself that is referred to as "the BCT"?
The reason for the question is that nvflash has a setbct and a getbct command, separate from the read and download commands, which work with the partitions.

so, we possibly share more internals with the 10s than previously expected? maybe... can we get this thing to dual boot in the future??

My guess is yes, the platform of the ac100 laptop by toshiba is tegra based and they do it!

The set bct command probably write the 4080 byte to the partition named bct in the cfg, I have yet to test flashing a dummy FF filled partition with the command to confirm the flash.bct get writen there
So in fact when you restore with the nvflash restore images from bekit I think you are actually writing it twice... (it is in the image and you telling the nvflash to create it) but I have not confirmed this yet
Once the bct info is there, the SOC read his configuration there, as well as the ODM info, I have not found a way to use --getbct that reads back the BCT from mass storage yet...
I am not sure either why there's so many section being flashed it should work with only a few of those (I plan to test this) since nvflash is simply puting those one after the other. It make sense only sense for a dual booting unit

Hi,
I was able to get --getbct to output a 2048 byte file awhile ago. I think I had posted about it, but, sorry, I don't remember which thread. The only thing I vaguely remember was that I had to use some unobvious combination of parameters. Also, I think that it only worked right after pushing the bootloader.bin. If I find my post, I'll provide a link.

Thanks OP, I like the idea of being able to back up the partitions directly from my tablet so I know I'm restoring the proper thing should I ever have to resort to that.
Just starting to get into modding this thing after it showed up from Woot yesterday, been planning on buying one for quite some time to compliment my Epic 4g and when the woot sale dropped I had to jump on it. So far all I have done is flash clockwork, and make a nandroid backup with that. Also doing this backup method now.
So have you actually done a successful restore using this method?

so is it possible to back up your original hardware configuration and restore it when you got problems???

Yes and NO, I have error reading partition #11 (system) on my tablet (bad block)
if I use it as is for restore, it doesn't restore and boot, however replacing this partition with clockwork system.img backup give me back a full working tablet.
I can also reboot into recovery and restore from there.

Letters and numbers oh my
I ran the backup on my new replacement GTab yesterday. I had a size mismatch on partition 5, everything else backed up properly. Also, my partition 7 is BLO and partition 6 is MSC. Thanks for the script and capability.

Instructions on how to flash back using this would be great. I'd like to have the option to do so if I need to, but haven't gotten familiar enough with nvflash yet to figure it out on my own.

You can flash back the partition using
"nvflash.exe" --bl bootloader.bin --download X partX.img
where X is the partition number you wish to flash, as stated you can also use your backup from clockwork mod for partition 11 restore.
If needed you can use the nvflash format kit prior to restoring however it would be better to use your own .bct with that option

What is the error you are getting ?

stock recovery image
Thank you very much for the sharing this.
Now I have 10 img files (part-2 to part-11)... wich one is the stock recovery image? I did this before installing clockwork mod...
Thanks!

I think this is fantastic. Gives us a chance to backup our gtab before deciding to try a new rom. I tried this today in the hopes to backup and then install the flashback HC rom. But unfortuntaly it stopped on image 7, as xkwwwx has also mentioned. The message seemed to be a issue with the size expected of the image as to what was received. Ill try and copy the message.
"nvflash.exe" -r --read 7 part-7.img
nvflash started
[resume mode]
receiving file: part-7.img, expected size: 16777216 bytes
/ 131072/16777216 bytes received
At that point it stops, and i have to control c to exit the batch file. Id love to be able to backup with this pls, so i can try another rom, and know i can use this to return to this rom if i dont like the new one, any chance this can be resolved pls ?
Was also wondering if some form of GUI maybe of benifit, i know alot of people feel wary of NVFlash, perhaps with a GUI people would feel more comfortable using it. Maybe a simple screen with a backup and restore set of buttons ?

P00r, any chance you can help mate ? Cant use this unfortunatly because of the image size issue.

This mean you probably have a bad block in this section, try skipping it to get the other parts first. this is not a major issue, you may also encounter one in the last data section (my tablet has a few byte less than the regular one)
For the data partition you can substitute the cwm images
Also try using a different bootloader and nvflash this can help even shorter usb cable or a different one can help
The part that you can read is probably usable for a restore anyway
Bad block are not unusual in flash and I have seen a few with this, ideally and usually it's located at the end, you could try using the format image a few time it could be a stuck byte and writing different data can revive it (format write FF all over)

Bad blocks may be common, but bad blocks in the exact same spot probably not. I get the exact same thing:
"nvflash.exe" -r --read 7 part-7.img
Nvflash started
[resume mode]
receiving file: part-7.img, expected size: 16777216 bytes
/ 131072/16777216 bytes received
Any other thoughts on this?

Maybe someone here knows,
So with NVflashing, I've found only one file that has the alternative BCT (it's a tnt1.0 rom on BL1.1) and no other NVflash file sets work without causing a APX bootloop.
This is the NVflash file set that works for me http://db.tt/FvSeAZj
Ive read it was made when someone was trying to configure for the hardware variations.
Now is it possible to take my backup and insert just the files needed into another NVflash file set?

Please do a full backup of the bootloader! So we all can fix our device..!
The procedure is easy and you just take about 8 minutes..
You have to download this tool (for windows)
http://www.roadkil.net/program.php?ProgramID=12
1- Download the tool "Roadkil's Disk Image"
2- Enter to pink screen (volume up and down, then power on)
3- Connect your phone to the computer through the backside usb port (its more safe)
4- Run the tool
5- Click on the "Store Image" tab.
6- In "Store Image to" click the combobox and choose "Physical Disk #" ("#" is a number)
* If there are more than one "Physical Disk #", then you have to choose the one that is about 3.6gb.. This part is very important.. if you give us a backup from another disk, it will leave our phone unusable.
*To be sure that that Physical Disk you choose is the Huawei u8800-51, You can run the tool again (because it has to refresh) without the phone connected, then check which disks are available. Then, close the tool again, connect the device (in pink screen), run the tool, and check what physical disk was added. But it will be about 3.6gb.
7- In "source file", save the file as "u8800.img" in a folder with more than 4gb of storage available.
*There is no risk for you, as it is just data copying, not writting. The risk is for us if you gave us a wrong file hehe..
*If you compress the "u8800.img" file into a "rar" file, the size will be about 700 mb, then please, upload the file into mediafire or some file hosting service.
Thanks man! It will be very useful to many people!
----
*For the ones who do the restore from the file, they have to do something to get the "u8800.img" to work. I will post here what do they have to do before writing to the disk, so Don't restore until I explain it here, or it wont work! and you may have errors!

im about to do it now and sorry im late i never got a chance to do it.

Ok I will post the tutorial later.. But about the 3g.. It is working, but you have to do factory reset after you restore from the linux backup..
Also, you will have the IMEI of the person who did the backup.. I tried to restore mine and I did it, but when I restored it, the 3g stopped working.. But in "about" it showed me my imei.. My IMEI backup was made when I already updated to u8800pro..
Maybe the files that this tool (5iromtoolbox) backup are the key for having 3g in the u8800pro rom.. (also with the libril-qc-1).. I dont know.. we should test it later..
Remember.. keep the original IMEI (not yours) and you will have 3g or H+.. whathever--
Advices:
- Do the full backup in Linux
- Backup IMEI (5iromtoolbox)
- Backup CWM
- Backup APN

[BackupTool] SM-G900P Backup Utility

Hi guys,
I created this tool so you can backup the partitions for the Sprint Galaxy S5.
This is IMPORTANT because the tools available at the moment don't backup your data properly. Trust me you don't want to corrupt your modem and then don't have a backup to restore it as they are easily corrupted when you play with network locks.
Password: ifyourhappydonate
Enjoy

What format does this backup to and how to restore?
Sent from my SM-G900P using XDA Free mobile app

This backup to bin format.This means it's a copy of the bytes of the partitions in your phone. I did not create a restore function yet but can be added on the next version as well as support to more devices.

Only G900P ?

Yes at the moment this is the only supported phone.

This tool is an quick tool that I created that is an automated process that uses adb to connect to the phone and create a backup and save them to the PC. This is because the available tools did not backup the correct information or are partial backups that are useless. I didn't add a verification for to see if the phone is connected but can be added later on. The files are stored in the same folder as the exe.
Requirements: Usb Debugging enabled only.

Still same results, i see commands being processed by the phone but they're all remove commands for the BIN's its supposed to have created, from the sdcard partition. Yet i still dont find these files in the STool folder or anywhere on my phone. That and it seems to backup/dump everything so quickly its hard to believe its writing to anything unless these partitions are SUPER small. Wonder if i need to flash back to a stock rom and try from there since i recently flashed over to RDDT fo play with the WiFi calling feature. I'll flash back to stock and see if that makes a difference.
Thanks again for your work on this!

Hey
Same thing on my side, I read it but cant seem to find the file and Im on stock....???

I guys sorry for the confusion it appears that any way this is not the way to backup the data specially for the modem.
Samsung really lock this thing down and encrypted the partitions for nv ram and isolated them through hardware encrypted communicators.
i have found how to access those files i will let you know as soon as it is ready.

Flashtools (MiFlash4Linux, Recovery from QDL/DLOAD, Partition resize)

Introduction
This is a collection of Tools and Resources for Flashing Mi2(s)(c).
MiFlash4Linux
https://github.com/M1cha/aries-image-builder
Core Recovery Package for MiFlash
This is a small package to Recovery MI2 from any bricked state. It has the following advantages over the official ones from Xiaomi:
They don't flash any ROM, just the core system(bootloaders, modem and recovery)
They are small which means both Download and Installation are faster
It directly installs custom Bootloader and TWRP. That means you easily get your device back to a modded status.
Please follow the official MiFlash guidelines for installation with the following differences:
the DLOAD config is called rawprogram_core.xml
the fastboot script is called flash_core.bat(or flash_core.sh for linux)
there's a script called flash_partition_table_and_core which is a alternative to flash_core.bat/sh.
It can be used to change the partition table.
USE THIS WITH THE CUSTOM BOOTLOADER INSTALLED BY ONE OF THE CORE PACKAGES ONLY. Xiaomi's bootloader will format your whole MMC device. THIS WOULD ERASE YOUR EFS AND YOU CAN'T MAKE CALLS ANYMORE
Changing the partition table
There are multiple packages available:
separated: Xiaomi's original layout with a virtual internal sdcard
separated_single: same as separated but without Dualsystem and bigger system partitions
unified: Xiaomi's new layout with /data/media support
unified_single: same as unified but without Dualsystem and bigger system partitions
unified_single_xiaomi: Xiaomi's version of unified_single
SkiFire13 said:
aries_core_unified_single.zip -> only MIUI > 5.4.x or M1cha's CM12.1 or latest AOSP5 works (only they can see Internal Storage, that now is a virtual sd-card in /data/media/0)
aries_separated_single.zip -> other roms
Click to expand...
Click to collapse
Installation:
Backup all your data(including internal sdcard, and EFS just to be safe)
if you don't use the custom Bootloader yet, flash this package using flash_core.bat/sh first. See the big red warning above for more information
flash the package using flash_partition_table_and_core.bat/sh
boot into recovery(which is TWRP now), recreate the filesystems for all partitions(system,data,cache,sdcard to ext4) in the wipe menu and reinstall your ROM.

Hey M1cha, thank you! Great job!
I have some issues about the procedure:
1. I am not sure if already had a custom bootloader, so first i'll flash the package flash_core.bat :
- turn on mi2s in fastboot mode
- plug usb, device should appear in miflash(the program should be configured as the photo?)
- and click flash
- reboot phone, enter in fastboot mode again and do the same procedure with flash_partition_table_and_core.bat
Is that right?
It's easy to recreate the ext4 filesystem in TWRP? always used CWM....

@m11kkaa: thnx for the linux tools/scripts, it made my migration from CWM to single-system partition + new bootloader + TWRP easier.
BTW, I just wanted to migrate and keep my current CM11 for the time being. I had to fight a bit with restore from backup because I was not aware of the incompatibility between CWM and TWRP, luckily enough it eventually was sufficient to:
reformat system, data and cache in TWRP
flash the old CWM temporarily and restore boot, system and data
flash TWRP again and make new backups.
Proposal:
It would be good if you can change the heading style of "Installation" in the OP to be the same as e.g "Introduction", because now it looks like part of "Singleboot Partition Layout" section only. It is confusing IMHO.
In my case (i.e. flashing both flash_core.sh and then flash_partition_table_and_core.sh), I had to recreate ext4 FS not only on the system partition in TWRP, but also on the data partition (it could not be mounted and TWRP announced 0 MB size) and eventually also on the cache partition. This seems to contradict the info in OP, part "Singleboot Partition Layout", which mentions that data will be preserved.

@cogano thx for your feedback
it's weird that u had to recreate the filesystems because the positions of these partitions still are the same. I resized system1, modem1 and boot1 to 2KB and system, modem and boot to 2*oldsize-2KB. I checked the offsets and they still are the same.

I have another phone and plan to do the same some time in the next week.
I'll try to avoid the trial&error approach and keep notes between the steps.
P. S. I am quite proficient with Linux administration. However I have to admit that upgrading android devices is usually a risky thing: I would have to read lot of guides - often unclear and confusing - or just give it a go and resolve the problems as they appear. The latter one eventually seems to be faster

If you don't have a ROM/Recovery with parted you can reboot to dload from the bootloader which will provide ur whole MMC as a usb drive to your computer.

i didn't see the download tab at first, so i downloaded the whole zip from the github and excuted the ./build.sh in Cygwin. Anyway, it works!

The heavy lifting was done by the twrpbuilder project who were generous enough to compile TWRP for our device. They also provide their services to see TWRP is available for devices that don't yet have it. I've personally used this version to do a backup and restore but can't guarantee there won't be issues. If there are while you are still in twrp you should go to the advanced section and copy the log to your external sd card. This log will help them diagnose any issues.
The project is located at: https://twrpbuilder.github.io
Their XDA thread is located here: https://forum.xda-developers.com/android/apps-games/twrpbuilder-t3744253
If you already have TWRP installed installation is as follows: Click Install, choose Image file, navigate to where the TWRP img file is located on your external sdcard and flash that img to the recovery partition. Back out to the root dir and you can select reboot then recovery...it should bounce you right back into recovery and you should see the new version loaded. If you have root in the rom and run into issues the app "flashify" can reflash TWRP 3.0 so make sure you also have it's img available.
This is pretty much only for folks who already have twrp to update to the latest. If you are on nougat you are still stuck until an exploit is released that works for nougat the way dirtycow did for marshmallow and below. *update* an exploit to give root to nougat users is now available thanks to @runningnak3d here: https://forum.xda-developers.com/tmobile-lg-v10/general/root-h901-nougat-t3773942

Looks to me like that URL should read

[ EDIT ] Yup, confirmed.. The URL I listed works fine.
Thanks for the file!

You are correct. For some reason a few characters got truncated. I've corrected the url in post #1.

Just as an aside, this version seems to correct (mostly) the date issue of previous TWRP versions for the V10. Versions before this one used to generate a default date (folder name) for the backup dating back to the 1970s as I recall.
This one has the correct month and day and time and the year is only 1 off - it showed 2017 on my very quick attempt to play with it.
One additional note to those installing it via TWRP itself - after selecting image flash , MAKE SURE you specify RECOVERY partition, not BOOT! Specifying BOOT will most likely have some less than desirable results.. :laugh:

I've passed on the date issue. Uncertain if he'll generate another build though.

Seems that either nobody is using this version or nobody knows about it or they just have nothing to say..
Anyway, as you know, I have spent a fair amount of time recently working with this and installing it. A couple of observations that may be worth noting..
I double checked and I did set a screen timeout on TWRP. Previous versions would first, dim the screen, followed by turning it off completely. If you had the device near you on a desk while backing up the screen lighting up again when TWRP completed was a sure signal that it was finished.
This version of TWRP dims the screen but the screen is never turned off completely. A minor annoyance I suppose but something is different from previous versions.
During the /data partition backup I noted a (to me) new display in yellow: "Backups of data do not include any files in internal storage such as pictures or downloads"
Seriously? Is this something new? Certainly the display is but I always kinda relied on all that being backed up with /data and having the ability to restore them. This is a more serious issue for me which may make me consider going backward..
Thoughts?

I use my v10 as my backup phone now. On my HTC U11 life when I make a nandroid it shows that it is not backing up files on internal storage. I think this is normal now on the latest version of twrp.

On your last issue this is business as usual...twrp has NEVER backed up the internal SDCARD unless you selected the sdcard entry in the list of sections to be backed up. DCIM (pictures) and the Downloads folder/dir have never been included.
As to the dimming, you can check in settings to see if something can be configured however each person compiling twrp can set their own options as to how they want it to function. There is no guarantee or expectation that Person B is going to use the same options as Person A. You are of course free to compile your own copy configured the way you would prefer it to behave but the process was enough of a pain in the butt I just requested twrpbuilder to generate one as I kept getting errors. The process to compile it also appears poorly documented.

I kinda suspected that but that is, at best, a questionable choice since I don't even have the option to check or uncheck a selection for it. Not happy..

Not quite. INTERNAL is not the SD Card. Internal is emulated sd on /0. In TWRP if you tap select storage, for example, you can pick "internal" or "SD" for backup destination, as one example.
I keep a fair number of things in /Download - things I grab in my travels, things I save there for later use.. whatever. I'll have to device a Tasker module or something for copying all those to the actual SD card...

A fairly recent app/utility created by @kdrag0n called Tipatch brings a long-needed resolution to the table regarding "full backups" of Data using TWRP. In a nutshell, Tipatch installs to your Android device as a basic APK. Within the simple GUI, once root permissions are granted (In-Place Patching) Tipatch will decompile, patch, recompile and flash the patched TWRP to /recovery, effectively patching your TWRP build to backup the contents of Internal Storage (emulated SD card) as part of Data itself, so that backups will now include those Internal Storage contents such as downloads, photos, videos, game data, and other various files. I've tried it on this particular build of TWRP and it works without any issues. There are options to patch TWRP without root permissions as well. There are Windows, Mac & Linux versions available too. If you are patching TWRP on a device with an A/B partitioning scheme, the patched TWRP can be installed on both A & B using a one-click option. Of course, one insurmountable caveat to patching TWRP with Tipatch is that wiping Data now will also wipe Internal Storage (emulated SD card). In short, the utility works on pretty well all device types and chipset platforms (Exynos, Kirin, Snapdragon, MediaTek, etc.). The latest Tipatch update, v1.6, includes support for TWRP builds that use LZMA compression, and removes the now-misleading notification previously listed when backing up Data -- that Internal Storage (/data/media/ path / emulated SD card) contents are not backed up. Anyway guys, here is a link to the Tipatch Discussion & Support thread: https://forum.xda-developers.com/android/apps-games/app-twrp-tipatch-backup-internal-t3831217
The latest Tipatch v1.6 app is also available on the Play Store and many other app & apk repos for Android. Versions for Windows, Mac and Linux can be downloaded using the above link.
