PS: I managed to extract the system.rfs file and the boot.img to the Working folder in the Kitchen.But i dont know about this,if i repack the room it wont boot and i think i know where is the problem but i need some expert point of view.When you tap: 1 and S in the kitchens menu it shows the format for each ROM.I didnt find system.rfs and boot.img as an allowed format so i decided to rename my system.rfs in system.img...when i done that the kitchen loaded my ROM.Then i made a backup copy of my system.rfs extract it with magic iso and clicked the next step on the kitchen extracting progress.Then i restarted the application and clicked the option 99 for repacking...i selected the 1 option then,i taped NO at zipaligning,i signed and renamed my ROM.The rom was created,then i copyed it on my SD.In CWD i selected install zip from SD,the process failed it gave me an error similar to : your updater script is...bla bla.I reentered the kitchen,i selected YES to convert my updated script the rest of the options were like above,copyed the ROM to my SD when i clicked yes to install id gave me an error about the boot.img.Now im thinking that by renameing my system.rfs into .img made a corruption on system folder tree and META-INF , because system.img is specific to HTC.your advice guys?what i did wrong?
Use Magic ISO to open and extract the files.

Sent from my GT-S5570 using xda premium
So, my phone recently got soft bricked....
I had the tar file of the XXELK4 leaked firmware and i extracted it, unpacked system.img.
Mounted it as ext4 and extracted the contents.
I want to make a flashable zip file from the system.img contents.
I made a folder called system. In which all app, bin, etc and other folders are.
Then i copied over the boot.img from the tar file...
Now, i need the meta-inf. I tried using some meta-inf from other roms, and removing the aroma functions from them.
Then trying to flash..
I get only a bootloop.
So, could someone provide a clean Meta-inf consisting of only the updater-script and update-binary??
Ive done a backup on my phone and created a flashable zip (update.zip)
Now im playing around with dsixda's kitchen and trying to extract the system.tar, however it fails most likely due to fact the the system.tar is empty
the files in the archive are as follows
Meta-inf -- <folder>
boot.img -- <8192KB>
image-edify -- <1KB>
system.ext4.tar -- <0KB>
system.ext4.tar.a -- <976,563KB>
system.ext4.tar.b -- <68,151KB>
By the looks of things it has split the system.ext4.tar because its over a gig
How can i compile this into one file or one image so that the kitchen can read it, I'm on a windows 7 PC but i can run linux in a vbox if necessary.
Thanks
Try using the zip file in your input folder.
dsixda's kitchen should be able to extract from it

Already tried, it comes back saying its deleting the part a and part b files and then says the system.ext4.tar isnt a valid archive.
Is it a stock rom?
If so, download the firmware from sammobile and put the tar.md5 file into your input folder (after removing the .md5 suffix).
Thats worked for me in the past....
It is stock, but i have removed the bloatware, installed a few mods, i was hoping to use this particular one really as a base. Ive already played around with fully stock and i kind of broke the whole thing
I'm not too sure then unless theres some tool you can find to merge the 3 tar files into 1...
Never had to do it so I'm unable to suggest anything I'm afraid.

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:

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...
I read somewhere that Google has changed the system used for the standard update zip file.
Therefore you have to convert some .dat files to .img files and .img files to a standard readable folder.
This I understand, however how do I reverse the process above to get back to the .dat file and get a lolipop compatible flashable zip?
