been searching for 5 days now :<
not a single answer found on google and forums
cant even post a new thread yet. just joined
hope someone will drop by this thread
still no solution?
got same problem here
Got a bootloop issue with an ASUS MeMo Pad 7 HD and I've booted in recovery <3e> to make a backup.
I've got a userdata_YYYYMMDD_HHMMSS.backup. I tried opening it with a bunch of tools like unyaffs, abe (Android backup extractor), going live on the file using linux tools (open as 7zip, zip, rar, tar, tar.gz, gz, bz2 , mount as iso, ext4 and so on....)
Still no luck :-/
Only clue is that the file seems compressed. During the backup under recovery, it told me 3600MB to backup and the file userdata_xxxxxxxx_xxxxxx.backup show only 2.61GB
I did this backup 3 time to ensure there were no corruption during the write process from the pad and did again the same "tests" to open the file...Not better.
If any dev' have any clue of the file format, I'd be glad to help
It doesn't seem to be a valid unix img file. Tried mounting it to no avail. When it's restored by the recovery it also extracts the individual files because i fails on one in my case and stops the entire restore... I tried unzipping it, changed extension to ,jar, .tar, .zip, etc., none of them are recognised...amazing for a standard android feature to find so little info about it
Any solution?
I called Alcatel's technical service today and they told me that you can use the backup file only from the phone. Mine gives me the following error when I try to restore it: Error Magic header
If anyone knows how to unpack the backup file I would be more than grateful.
It's a 512 byte header in front of a "tar.gz"
hexdump -C userdata_xxxxxxxx_yyyyyy.backup | lessshowed the magical zip header "1f8b0800 00000000" at offset 0x200
So, skipping 512 bytes, the rest can be gunzip | tar
dd if=userdata_xxxxxxxx_yyyyyy.backup bs=512 skip=1 | gunzip -c | tar xv
Sir ektoric what d u mean on ur post?
Sorry cant understand it..
Can u please d a step by step procedure? Please...pls...plss
Thanks in advance...
Steps?
@ektoric sir im a noob in this... Can u show a step by step procedure?
@killen00 sorry, I assume you have a linux machine (or have access to one). The command is actually all there is to it.
Code:
dd if=userdata_xxxxxxxx_yyyyyy.backup bs=512 skip=1 | gunzip -c | tar xv
If you don't have a linux machine available, might I suggest one of the many distros of your choice, most of which have LiveCDs which you can run without installing.
script for gunzip method
maybe on xda it is common sense, but for me it was necessary to know, that these stock android recovery extracted files can be restored with nandroid custom recovery, if you simply repack them into tar archive.
i put this two command lines in a dirty shell script (extract + repack as tar).
thanks to ektoric figuring out his gunzip method!
edit: notamamasboy's mount method added (but not tested yet). if script not works come back few days later, download again and check version, maybe it has changed meanwhile.
with this you're able to transfer data of non-rooted phone to (rooted) similar one.
this is useful in case touchscreen is broken, you haven't custom recovery installed, usb-debugging is disabled and connecting usb-otg-mouse doesn't work.
tested on my Archos 50 b Oxygen (Mediatek MT6582).
it works for me, feel free to improve, port to busybox and publish. no support. use at own risk.
edit: bckp2cwm.sh is deprecated it is FOR JELLY BEAN ONLY (no selinux support)
a newer (selinux) version bckp2win.sh for TWRP you can find here:
http://forum.xda-developers.com/showthread.php?t=3775129
How did you go about determining the magic number found at 0x200? My hexdump output does not have that magic number (1f 8b) in any instance. Leads me to believe my backup is not a tar file. Any suggestions then?
@notamamasboy, you are unfortunately correct.
Someone else also mentioned that their
Code:
userdata_xxxxxxxx_yyyyyy.backup
file was not of the same format I tried some "known magic headers", and could not find anything tell-tale. In which case, without some clues, you are back at square one.

Even more peculiarly, two backups were created a .backup and a .backup2, I wonder if combining with cat I can get somewhere...

Nandroid backups files (.img) created via Recovery are yaffs file system images. A tool called Unyaffs can be used to extract the files within these images (data.img / cache.img / system.img).
linux users can d/l the source code from: http://code.google.com/p/unyaffs/downloads/list
and compile using:
Code:
gcc -o unyaffs unyaffs.c
for windows users:
you can download the attached rar file and extract it...
usage:
1) copy the compiled unyaffs file/exe (along with cygwin1.dll) to a new directory
2) copy the nandroid backup image (data.img / cache.img / system.img) into that directory
3) go to terminal/command prompt, change directory to where those files are and execute:
e.g. for system.img
Code:
unyaffs system.img
the contents of the .img file will be extracted in that directory
there is also an app in the market YaffsExpert with which you can extract the .img files using phone

+1 nice post! very useful info for any Android owner, anyone ever backed up with nandroid or xRecovery and felt like they forgot something from one of their earlier backups...? This is what you need
Pretty nice and useful. I actually was tinkering around with these files the other day as I contemplated running either Z's Froyo Beta 4 OR J's GB
Thank you. It is very useful.
Great topic! Thanks

thanks. the reason i asked was that, everytime i try any rom from z, i get md5 error while restoring old backup. after extensive search in this forum and loosing my sms messages, i found a way. using adb shell, then using "busybox md5sum" i was able to generate the correct md5 hashes or whatever its called then restore the xrecovery backups. if i use the md5sum directly from the adb shell then xrecovery gives me mismatch.
may be z can look into this. i beleive the md5 mismatches are caused due to different md5sum command in adb shell and in busybox.

no need... the problem is with blanks /spaces " " in ur file name/ folder name... check that... if u have renamed the backups (folder name) and have space in it u will get md5 error... spaces in folder names are not supported...
no didnt change a single thing. even the filename which is the default timestamp.
Which version of recovery is that? Sounds maybe messed up. Using latest version helps.. just a thought

Hi,
The company Ainol release their latest updates as img files which we than have to flash using a program called livesuit. Does anyone know the process (or have any tips) on converting these img files to clockworkmod zip files?
I can extract the system and kernel files using something similar to this tutorial: http://www.techknow.t0xic.nl/forum/index.php?topic=1679.0
That tutorial explains how to modify the img file and then repack as img. I tried moving the system directory and the kernel & ramdisk over into a clockworkmod zip that i know works and overwrote the files in that with the one i had extracted.
when i try to install it, i get the e: cant open cwmzip.zip
(bad)
any ideas? Maybe i need to get the updater binary from the extracted files somehow?

It really all depends, how many images? What are the images called? What are in each of the images if there is more then one?
thanks for replying, i think i have it right. I ran a log and saw that there was an invalid filename in my zip and sure enough, i looked in the app folder and saw a file with a lot of chinese characters. Deleting this file has sorted this problem
Thanks for replying anyways!
Description: Utility (hereinafter - the kitchen) to make changes to the firmware image for the Lenovo K900.
Operating System Requirements: Any Linux-like system (I recommend Ubuntu), any digit. For correct working kitchen must be installed packges: p7zip, p7zip-full, jdk, jre, python, ia32-libs.
Features: Removing the preinstalled Chinese software from the VibeROM firmwares; other firmware - manual; deodexing firmware; adding ROOT rights in firmware; editing build.prop; installing Google apps (* not verified), repacking the system.img.gz image.
Instructions for use:
- unpack the archive to any folder;
- Run the kitchen with console command ./kitchen.sh and enter the root password (required for file operations);
- Copy the file system.img or system.img.gz in a folder /in/;
- Enter 1 if throwing system.img.gz image archive folder in /in/, or go to step 2 if the folder /in/ drop files system.img;
- Type 2 to mount the image, while in the kitchen wearing the phrase "System: unmounted" will change to "System: mounted". The system is mounted in a folder /mount/;
Then simply describe the menu items:
3 - removes Chinese preinstalled software according file cn-apps in /scripts/ folder;
4 - "easier" firmware by deleting unnecessary files, animation off; applies mods - Record video to MP4, boot animation changed to "clipped " (you can change your folder /scripts/mod/);
5 - deodexing firmware (it takes quite a long time , up to 10 min);
6 - adding ROOT rights (used SuperSU 1.93). If you want to use a different version, you can replace the files in the /scripts/root/;
7 - editing build.prop file by using gedit;
8 - Set the Google apps light with a minimum set of software, you can further install more right already from Google Market (not tested);
9 - edited image packaging system system.img.gz. Ready to pick up the file from the folder /out/;
10 - unmount mounted image. Performed at the end of all operations with an editable manner;
0 - unpack inb firmware;
x - exit.

if you need linux just for cooking, dont install it to harddrive.. just throwit on some usb drive and run it live..
use pendrivelinux or yumi to make live linux on usb.

Good morning,
to start my kitchen, I download the original VIBEROM image file, redhookbay-ota-VIBEROM_V1.0_1418_DEV_K900.zip but if I extract it on the "IN" folder I haven't the .img packages to mount (e.g. the system folder is already unpacked):
Also, after that, I get only the system.img file but in other release I used before, e.g. the one for the VIVO, I had the way to pack directly the image to flash. Here which one is the next step?
Thank you,

redhookbay-ota-VIBEROM_V1.0_1418_DEV_K900.zip - this is ordinary zip file, K900 kitchen is not working with OTA zip archives. To start working with kitchen you need to put in the /in/ folder only system.img, system.img.gz, or any INB file (to unpack it). Only like this.

Hey guys,
I'm currently in the middle of developing my own ROM for an S802 based TV box (M8). I am close to releasing but I have a few issues, one very much in particular. I am trying to find a script that will extract a .tar file to the /sdcard/ directory on first boot of the ROM but I'm having a hell of a time. I am a reseller of these boxes and I'm trying to get my Kodi userdata to extract into the proper directory, /sdcard/Android/data/, on first boot but nothing I do seems to be working. Currently I'm using a script called installApk.sh. From what I've gathered it works fine for extracting .tar files to non-sdcard directories but when I attempt to point the extract path of the tar to the /sdcard/ directory it fails. I've also tried decompiling the kodi apk, injecting all of my userdata directly into the apk and re-signing but that causes all of the addons to fail. I'm wondering if any of you have run into a similar issue or know a solution to my problem. Any help is appreciated. Thanks.

see Introduction : How to build an Android ROM - XDA-University
[GUIDE] [how to] CREATE OWN ROM [FOR ANY ANDROID DEVICE] [FOR N00B] [EASIEST METHODS] by lokeshsaini94
This thread will be moved to Android Q&A, Help & Troubleshooting
While trying to create my first ever Android firmware I had solve several problems, especially if you consider that I prefer under Windows instead of Linux.
I won't go into too many details as I have to assume everyone attempting this did at least some reading on the general how to of firmware installations and modifications.
Things you need:
Original firmware for your device as a IMG file
Amlogic's Customisation tool
A Rom Kitchen of your choice (I use Carliv)
System_Extractor-WIN-master
Some time...
Step1: Load the firmware into the AML tool and tick all boxes except the last one.
In the tmp folder you will find the unpacked files.
Under Level one are the files we want.
You will see a bunch of "PARTITION" files, we copy the following ones into a seperate folder for further use to create the ZIP.
I suggest to name the folder "Install" so we are all on the same page here.
boot.partition
bootloader.partition
logo.partition
recovery.partition
If you checked a flashable ZIP update before you will notice some files are missing, let's try to fix that.
Rename all partition files you copied to img, so instead of boot.partition you get boot.img.
Unpack the boot.img with your kitchen.
You will find a file "boot.img-second" - copy that into your install folder and rename it to dtb.img.
Inside the unpacked ramdisk (In your kitchen) of the boot.img you will fing the "file_contexts" file - copy that into your install folder as well.
Most AML firmware I had so far used a system.new.dat and a system.transfer.list to create the system partition.
We can create them from the system.partition file after renaming to system.img in System_Extractor-WIN-master .
To do this the system.img needs to be unpacked and we need again a copy of the file_contexts.
After the image is unpacked we can pack it again as system.new.dat and system.transfer.list.
The last missing bits can be tricky though as now we need a META-INF folder that works for our device in question.
There are two way to fix that.
Method one:
Search the usually chinese websites using Google to find original firmware for your device.
Chance are that you will find something like an OTA update - in there you will find what you need.
Method two (I never tested that):
Take the META-INF folder from an OTA update of a box with identical hardware specs.
Most important part here is the memory configuration so for a 2/16GB box you need a 2/16GB OTA update.
Next of same importance is the WiFi/Bluetooth config.
If you only have Wifi than an update for a box With daul wifi and BT4.0 won't help you.
If the actual Wifi chip is a different one but CPU, GPU, Memory and connections are the same it should still work.
Once you have the META-INF folder included into your Install folder the firmware is ready to be zipped - in theory!
The X96 for example uses a hash check for the update and created system partition.
To be able to flash your image you need to know what the original recovery would expect - has check or not.
The updater script within the META-INF folder needs to be updated to match your build.prop details as well hash check/no hash check.
Again, with an original OTA update you will find these infos.
Only if you don't have the OTA and no clue what your updater script and recovery needs you are a bit lost.
I know I has not all the steps in detail and if you are without and OTA update you need to search but otherwise feel free to ask and I will try to assist to make it complete if I can.

The X96 for example uses a hash check for the update and created system partition.
To be able to flash your image you need to know what the original recovery would expect - has check or not.
The updater script within the META-INF folder needs to be updated to match your build.prop details as well hash check/no hash check.
Again, with an original OTA update you will find these infos.
Only if you don't have the OTA and no clue what your updater script and recovery needs you are a bit lost.
I know I has not all the steps in detail and if you are without and OTA update you need to search but otherwise feel free to ask and I will try to assist to make it complete if I can.

Will see if I can at least add some pics while working on Nougat.
Hello,
Thanks for you tutorial.
I have a h96 Pro+ and the last firmware was a .img file... (Link of the firmware : https://mega.nz/#F!d1tHVZgA!Qc0mAom7FBHT9HDv3rGtGQ )
Is there a good guy who can convert this .img to a .zip file please ?
A lot of users are asking for this, me too and if you can help me to do this it will be really cool and appreciate
Thank you,
Carmin.
