[SCRIPT/HOW-TO] Sign files with terminal (Ubuntu)

sign files with a right click (Ubuntu) (Thanks Amon_RA)
-----------------------------------------------------------------------------------------------------------------
This little novice, 2-line script will help you sign update.zip files directly from any terminal window if you have the Android SDK set up on your machine. It might be pointless to some, but I thought it would be a nice idea to share.
Navigate to your Android SDK directory.
Create a folder and name it "sign".This is where you will put the update.zip that you want to sign.​
Download the attached testsign.jar file [extract from zip] and move it to the new /sign directory in your Android SDK.
Navigate to your /tools directory and Right-Click > Create Document > Empty File.
Give it a name without extension.example: sign​
Right-Click > Open with "Text Editor" and add the following:Change the directories according to your setup.
#!/bin/sh
java -classpath /AndroidSDK/sign/testsign.jar testsign /AndroidSDK/sign/update.zip /AndroidSDK/sign/update-signed.zip
Click to expand...
Click to collapse
Give it executable permissions with the terminal -
Code:
cd /YOUR-SDK-DIRECTORY/tools/
chmod a+x sign
Now you can simply drop the update.zip to your /sign directory and from the terminal type:
Code:
sign
and it will sign it without having to add the long command yourself.
Of course you can edit the script to fit your needs.
---- Optional ----
By making a link (right-click > Make Link) of your /sign directory and adding it to your Desktop, you can drag and drop update.zip directly to this link and sign. This save you some time in the signing process and you have access to it from your Desktop.

Thank you Cyanogen for this reply.

mods, please sticky this as i'm sure many will find this very informative

Perfect howto, just works like a charm Thanks to the author!

Thank you so much! Just started using ubuntu in a VM. Think you could write up a guide on setting up eclipse? That'd be absolutely super. Thanks again lol. Helped me sign files + set up the sdk. Great work.

Well, setting up eclipse is fairly simple!
download Eclipse
unzip it any directory/AndroidSDK/Eclipse | /home/wddglr/Apps/Eclipse​
set up the ADT following the information in this page: [http://developer.android.com/sdk/1.5_r3/installing.html]

Ah thank-you. I'll PM you if i run into any problems if thats okay. I'm a noob with ubuntu just set it up yesterday.

i love you man j/k
THANK UUUUUUUUUU so much man

if you use lots of different named update zips.
This is step 6
#!/bin/sh
echo -n "Source Zip Filename : "
read input
echo -n "Output Zip Filename : "
read output
java -classpath /androidsdk/sign/testsign.jar testsign /androidsdk/sign/"$input" /androidsdk/sign/"$output"
echo "Finished signing $input as $output"
Click to expand...
Click to collapse
Just input the source file and the output and it does the rest.
Was useful for me as I sign different zips.
Use as you wish, thanks to wddglr.

I don't know why I can never get this to work.
This is exactly what I see when I ls /AndroidSDK/sign:
[email protected]:~$ ls /AndroidSDK/sign
testsign.jar update.zip
[email protected]:~$ sign

I was wondering if you were you able to solve this? Becouse I'm getting the same.. I'm thinking it has something to do with jave. But not sure what I need to do to fix it.. thanks for any info ....

yea me toooo
edit i figured it out
Code:
# Right-Click > Open with "Text Editor" and add the following:
Change the directories according to your setup.
Quote:
#!/bin/sh
java -classpath [B]/AndroidSDK[/B]/sign/testsign.jar testsign /[B]AndroidSDK[/B]/sign/update.zip /AndroidSDK/sign/update-signed.zip
yeah that is not where my tools are lol

Yeah, I got it to work. The problem was with my Java.

testsign.jar in wrong spot
I got mine fixed. I had testsign.jar inside of the testsign folder inside the sign folder.
testsign.jar needs to be in the 'root' of the sign folder, or you need to modify the sign script to point to the correct location.

Now I am getting this error:

Command 'psign' from package 'radiance' (universe)

Help?

I guess it means I've failed???

This script worked great, I really appreciate it. I did modify it a bit so that I don't have to necessarily sign update.zip every time. It is similar to the script posted on the first page, but rather than it asking for the input and output, you simply add parameters to the sign command. For example:
Code:
sign <input> <output>
See the code below, make sure you change the directory to where you have the sign folder located.
Code:
#!/bin/sh
java -classpath /opt/android/sign/testsign.jar testsign /opt/android/sign/$1 /opt/android/sign/$2
echo "Finished signing $1 as $2"
Hope this helps anyone.

An even better modification is to make it only take ONE parameter:
#!/bin/bash
mv $1 /tmp/$$-$1
java -classpath /opt/android/sign/testsign.jar testsign /tmp/$$-$1 $1
rm /tmp/$$-$1
Note that this form is also independent of the location of the archive to sign -- it is nicer to enter that particular directory and just run "sign file.zip".

You should really mention that the tools directory has to be added to $PATH..
Not everyone has this, if you don't then simply typing sign will not work

Well it should be correctly assumed that $PATH was correctly set when they installed the Android SDK, because if they followed the instructions provided by the SDK's documentation then it says to set the $PATH var in "~/.bashrc" or "~/.bash_profile".
From: http://developer.android.com/sdk/installing.html
On Linux, edit your ~/.bash_profile or ~/.bashrc file. Look for a line that sets the PATH environment variable and add the full path to the tools/ directory to it. If you don't see a line setting the path, you can add one:
export PATH=${PATH}:<your_sdk_dir>/tools

[GUIDE] How to create a your own ROM

How to create your own ROM update.zip for the T-Mobile MyTouch 3G
Things you will need to perform this:
Java SE Dev Kit from Sun. java.sun.com
May need Cygwin with zlib0 package, from cygwin.com
This will give you Android 1.6 with all the Google applications, Root access.
I never found one place where all this information is all together, so that is why I compiled this together.
Now anyone can do this themselves.
Thanks to all the hard work others have done before this.
1.
First Root your phone and install a new Recovery image, either Amon Ra or Cyanogens Recovery image.
Instructions for one-click root: http://theunlockr.com/2009/08/22/how-to-root-the-mytouch-3g-or-g1-in-one-click/
2.
Download the Android 1.6 System image from
http://developer.htc.com/google-io-device.html
extract the contents of signed-google_ion-img-14721.zip.
3.
You now need to extract the contents of system.img using a tool called unyaffs. The source code is here:
http://code.google.com/p/unyaffs/downloads/list
Or download a prebuilt win32 version here.
http://jiggawatt.org/badc0de/android/index.html
Note you may also need cygwin1.dll and cygz.dll (zlib0 package). Found at cygwin.com
Of course if you already have Cygwin installed with the GCC packages, you can just compile it yourself. Then also
if you comment out the line 67 to "// symlink(oh->alias, full_path_name);"
then it will not create the copies of the symbolic link file, and you will not have to worry about deleting duplicate
symbolic link files later.
Now in the directory where system.img exists, create a new directory called "system"
go into the "system" directory.
type the following command:
unyaffs ..\system.img
That should extract all the files from the system.img file into the system directory.
4.
Now we just need to clean up some items. Since the system.img is a linux file system, it has symbolic
links built into it, but when we extracted it, it just created duplicate files, if you used the prebuilt unyaffs.exe.
So we can just delete the duplicates and have a script recreate the symlink on install.
So we need to delete some extra files from the system\bin directory.
Run the attached DeleteExtras.bat file from the same directory where system.img is in.
If you notice, all the files it deletes are 28 byte files, and if you open them in notepad only contain:
"!<symlink>toolbox..."
And we will remake the symbolic link when it is installed.
5.
Now from the directory where the system.img is, enter the following commands
mkdir META-INF
mkdir META-INF\com
mkdir META-INF\com\google
mkdir META-INF\com\google\android
Now copy the included file "update-script.txt" into the "META-INF\com\google\android" directory
and RENAME it to just "update-script".
This update-script gets run to recreate the symbolic links.
Not sure if these two are needed but they are in some custom ROMs here:
Copy the two files "fix_permissions" and "flash_image" to the "system\bin" directory.
6.
-- Optional --
These add root and Superuser access to the ROM, plus the Terminal Emulator application.
Copy the file "su" from Cyanogen's rom to the folder "system\bin"
Copy the file "Superuser.apk" to the folder "system\app"
Copy the file "Term.apk" to the folder "system\app"
You can also replace the "system\etc\apns-conf.xml" with a more complete one from here:
http://forum.xda-developers.com/showthread.php?t=547718
or here
http://docs.google.com/Doc?docid=0AZNbAmKkmakoZGZxZHNwMnpfMjJkaHg3ejN3eg&hl=en
Turn data roaming off by default by editing line in the build.prop file:
ro.com.android.dataroaming=false
Also to fix the Market program to show "Protected" applications change the ro.build.fingerprint line to the following:
ro.build.fingerprint=tmobile/opal/sapphire/sapphire:1.5/COC10/150449:user/ota-rel-keys,release-keys
Only phones with a fingerprint of a "released" device can access some market applications.
--------------
7.
Now we just need to create a ZIP file for the final ROM
Zip up the following file and two folders:
boot.img
META-INF
system
8.
Now sign the zip file.
See here how to sign a ZIP file for flashing it.
http://androidforums.com/developer-101/8665-how-signing-roms.html
9.
Copy it to your SD card, boot into recovery, wipe, apply the update, Reboot.
You are now running Android 1.6!

the finger print is found in build.prop is this correct and what app do you use to edit your build.prop

Yes the fingerprint is in build.prop
Make sure to use an advanced text editor like TextPad, UltraEdit, or EditPlus. It has to handle UNIX text files.
Also use this for the update_script.

how abt kernel parameters?

Would like more info on hot to incorporate senseui

Thanks for sharing... Got nothing to do today, so I experimented on my phone... I gotta say, I'm pretty amazed w/ this feature. Was able to sort out and organize my files.
Kudos!

How does one create the system.img file once one has the system files...
What I want to do is use some of the custom roms here and put it on an AVD emulator system.
Can someone help with this please.
NOTE: I dont have linux. So if there is an alternative to mkbootimg, it will be excellent.

the ion is the 32b if I'm not mistaken?
Is there an image for the 32a or do we always have to use the ion and throw a patch over it?
Sorry if this is a stupid question

in step 5. it says
Not sure if these two are needed but they are in some custom ROMs here:
Copy the two files "fix_permissions" and "flash_image" to the "system\bin" directory.
Where do i copy the files from or download please?
thanks in advance
P.S. any tips on changing the splash screen would be much appreciated.

DeleteExtras.txt or DeleteExtras.bat doesn't work. I have to delete the extra files by myself - one by one.

check this: http://forum.xda-developers.com/showthread.php?t=633246

Perhaps someone here knows or could point me to the right resources, but if the phone isn't supported by Cyanogen, how would a custom rom be made in that case?
How is a custom rom made from scratch? Since android is just linux, is it simply a matter of building it with the right drivers for the phone and installing it? How can an image be manually copied to the phone if it isn't supported by Clockwork recovery? How can it's steps be manually done?

ping pong...

Can i install my own rom on samsung ace?????

anybody knows how to make a ROM customized and make a "update.img" to run on a un-rootable device? I know when you backup a linux image for example ubuntu, this image will run on all other PCs, the image will automatically knows the new PC's drivers and adapt everything with that, is it what happening to an android too ?
---------- Post added at 08:36 AM ---------- Previous post was at 08:33 AM ----------
and pls let me know how to open/edit a "update.img" file, thnx

[Tutorial] How to port cf-root to other i9003 Firmwares [23/02/2012]

Tutorial for Porting Cf-root To Newer Firmware's
There were quite a few requests for a tutorial to create ginger bread cf-root. So here it is folks.
Big Thanks to skin1980 for helping me out.
Credits:
Chainfire for the cf-root.
Skin1980 for porting it to Samsung Galaxy SLCD.
Prerequisites:
Any Linux. Basic knowledge of linux is mandatory.
Tools for Unpacking and Packing images.
Base Samsung Galaxy SLCD Gingerbread Cf-root.
Samsung Galaxy SLCD Gingerbread Firmware ROM for cf-root creation.
Downloads & Setup
Any Linux: For this tutorial I am using Linux Mint KDE. You are free to use the Linux of your choice. Ideal starting point for downloading and installing Linux would be Distrowatch.com.
Tools for unpacking and packing images: These are sets of tools that allow you to unpack and pack boot images. Basically one requires just a few tools to achieve.
Link to Download: cfroot-tools.zip - 19 KB.
Download and exatract it into your home folder. It will create a cfroot-tools folder under home folder. Go to the folder and execute the following comand:
Code:
chmod +x *
Base Cf-root: Download any latest cf-root from this Link. Extract the normalboot.img from the cf-root tar file.
normalboot.img: Require normalboot.img extracted from downloaded Gb ROM.
Hex editor: You will require and Hex Editor. I am using bless hex editor. You can use any one which you are comfortable or the one available under your linux distribution.
Open terminal window and enter the following commands:
Code:
[FONT=Microsoft Sans Serif][SIZE=2]cd
[/SIZE][/FONT][FONT=Microsoft Sans Serif][SIZE=2]gedit ~/.bashrc[/SIZE][/FONT]
You can use any editor of your choice. The main purpose is to set the tools path. At the bottom of this file, add the following lines:
Code:
PATH=$HOME/cfroot-tools:$PATH
export PATH
Save and close the file.
Logoff from linux and login again for the new path to take effect.
The Actual Process
For the purpose of tutorial, I am going to use XXKPQ cf-root as the base and DDKP3 for creating new one.
Create a folder called “cfroot” with out the quotes under home.
Go to the created folder and create two more folders: DDKP3 and XXKPQ.
Now copy the normalboot.img extracted from XXKPQ cf-root and copy it into the XXKPQ folder. Next copy the normalboot.img fromDDKP3 firmware and copy it into DDKP3 folder.
Now go to the cfroot-tools folder under HOME and copy the decom.sh and recom.sh into XXKPQ and DDKP3 folders.
The above steps can be accomplished by the below code. Open command window and type the following:
Code:
cd
mkdir ~/cfroot
mkdir ~/cfroot/XXKPQ
mkdir ~/cfroot/DDKP3
cd ~/cfroot/XXKPQ
cp ~/cfroot-tools/*.sh .
chmod +x *.sh
cd ~/cfroot/DDKP3
cp ~/cfroot-tools/*.sh .
chmod +x *.sh
You need to press enter after each command.
From terminal window, first to change directory to XXKPQ, type the following commands:
Code:
cd ~/cfroot/XXKPQ
./decom.sh
After the execution of the above command, the following files and folders will be created:
normalboot.img-base
normalboot.img-cmdline
normalboot.img-pagesize
normalboot.img-ramdisk.gz => Ramdisk
normalboot.img-zImage => Kernel
Click to expand...
Click to collapse
Apart from these files, a folder called ramdisk will be created, into which the contents of normalboot.img-ramdisk.gz would have been extracted.
Now once more from the terminal window execute the following command:
Code:
cd ~/cfroot/DDKP3
./decom.sh
Also make note of the following values, which are shown, when the decom.sh script is executed.
Code:
BOARD_KERNEL_BASE 81800000
BOARD_PAGE_SIZE 00001000
Now under DDKP3 folder, edit the recom.sh file. Replace the value after --base with the value after BOARD_KERNEL_BASE. Replace the value after --pagesize with value after BOARD_PAGE_SIZE. Save the file.
Now we can switch to file manager. It will be easier to work using a file manager from here on. Open the XXKPQ/ramdisk and DDKP3/ramdisk folders separately in file manager.
Copy the folders res & sbin from base cf-root (XXKPQ in our case) and paste into DDKP3/ramdisk folder. Overwrite all when prompted.
Copy all the files under XXKPQ/ramdisk (in the root) to DDKP3/ramdisk.
From XXKPQ/ramdisk/lib/modules/2.6.35.7/kernel/ copy the fs folder into DDKP3/ramdisk/lib/modules/2.6.35.7/kernel/.
At this point of time, we no longer require the XXKPQ folder. So we can close the file manager window browsing XXKPQ folder.
Now comes the tricky and critical part. This must be done very carefully. We need to edit the .ko files using a hex editor.
Under the kernel/crypto/ folder, there is a pcbc.ko file, edit it using an hex editor. Search for 2.6.35.7 using find option in the editor. Now note down the six digit numbers starting immediately after 2.6.35.7-CL. In our case the magic number is 882023. Close the file and the editor.
Now we open the kernel/fs/ folder in the file manager.
Now open the mbcache.ko file in the hex editor. Search for 2.6.35.7 again. As we can see that the six digits after 2.6.35.7-CL is not 882023. In our case it is 709629. We need to change 709629 to 882023 and save the file. Different editors provide for different methods of editing. In my case I can just simply click on starting number that is 7 and start typing 882023 and save the file.
Now you need to do the same for two more files under kernel/fs/jbd2/ and kernel/fs/ext4/.
Now go back to ramdisk folder. Under ramdisk/sbin/boot/ there is a file called install.sh. We are now going to edit this file. This not important that you edit this file.
Edit the first line and replace XXKPQ with DDKP3.
Similarly under the “# Once be enough”, there is another XXKPQ which is to be replace with DDKP3.
Now save this file.
Now back to command prompt and execute the following commands:
Code:
cd ~/cfroot/DDKP3
./recom.sh
Executing the above script recreates the normalboot.img-ramdisk.gz, the normalboot.img and create DDKP3-CFROOT-16-02-2012.tar.
The DDKP3-CFROOT-16-02-2012.tar is the cf-root for DDKP3 and can be flashed using ODIN as Pda file.

Thats it folks. Hope my effort is worthwhile and benefits some of you.

Thank you Ganeshbiyer! this is the tutorial for which send multiple private messages and never answered .. Thanks again, nowI can make a version for Gingerbread UBKPD.
goodbye

Yeah ganesh! A superb work..well done bro

thanks bhaiya....

Thanks for the tutorial buddy

Hope it has been useful.

Release all PERFECT! I had no problem in making the entire guide .. BUT ... when flashing in ODIN, and says that when it failed to finish.
I knew that I would be so easy, so I started to analyze both folders (my UBKPD and XXKPQ) and did not get that at the root of KPD I have 12 files and only 11 KPQ. The 12th file executable type KPD called RECOVERY. This file should remove it before using recom.sh?
Thanks again for the guide. goodbye
Edit2:
Well, my little patience led me to delete that file and then went back to RECOVERY recom.sh run and throw me error that could not erase normalboot.img and did not understand, but looking at the files in the root, not the size you normalboot.img was higher than the stock then replace the stock normalboot (+5 mb), run again and finally he created recom.sh cf.root, I flash with ODIN successfully without any problem in these +30 minutes.
Thanks (again).
Now I have as including UV & OC (freqmax 1100MHz is very good speed and would think you do not need more with this phone)

maybe a stupid question:
would it work with other phones as well? natually with the files of the other phone and not with the 9003 files

greetings fabsau

i do it all at this tutorial and it create .tar fine without trouble.. i flash with odin also no problem happen.. but while device open.. at boot logo get stuck or freeze at long time.. why it happen???
i confuse with this line:-
-Copy the folders res & sbin from base cf-root (XXKPQ in our case) and paste into DDKP3/ramdisk folder. Overwrite all when prompted.
-Copy all the files under XXKPQ/ramdisk (in the root) to DDKP3/ramdisk.
-From XXKPQ/ramdisk/lib/modules/2.6.35.7/kernel/ copy the fs folder into DDKP3/ramdisk/lib/modules/2.6.35.7/kernel/
Click to expand...
Click to collapse
why do not copy all the file in ramdisk n skip copy file inside the ramdisk folder.. it is difference?? please tell me if i do a mistake.

[GUIDE] How to extract system files from stock firmware

Ok, so I know many users are looking forward to create a custom rom. Where are you gonna get the system files from? Sure you can get it from a CWM backup. You can also extract the system files and the respective kernel from PDA.tar. Sure everyone knows it's in there but very few exactly know how to extract them. The system files are in the file "system.img".
So the 1st step is to open the PDA.tar using 7-zip and extract the system.img to a particular folder.
Download sgs2toext4.jar from attachment. It's a .jar file created by dphrozen to convert .img files to .ext4.img. Place that file anywhere in C:\ and then open the Command Prompt. In the command prompt, set the directory to the folder where sgs2toext4.jar is placed. Then type this command :-
Code:
java -jar sgs2toext4.jar
A window will open which is gonna ask you to drop the .img file in it. Simply drag the system.img to the window and the process of converting it to system.ext4.img will start. After the process is complete, you'll find system.ext4.img file in the same folder where your system.img file was placed.
Now, download Linux Reader. Install and then open it. At top left, go to Drives -> Mount Image. A window will open up. Browse to system.ext4.img and select it.
That's it! Now you can view all the system files. Export all of them to a particular folder. After exporting, you'll see an extension .efs.ntfs at the end of each file. Just delete that extension and you're good to go!

[Q] unpack userdata***.backup from cwm on windows

Hi/Hello/good evening!
I have a broken MTK phone waiting for spareparts and one backup file from its SDCard made with CWM
name userdata_20130615_140224.backup where I need to extract contact data from.
How to do it?
I have been searching a whole while now but could not find one single post about opening this archive.
Pls help!
Thank you,

It's a 512 byte header in front of a "tar.gz"
hexdump -C userdata_xxxxxxxx_yyyyyy.backup | less​showed 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​

Code:
dd if=/home/user/_backups/E380-android-phone/userdata_20160126_223433.backup bs=512 skip=1 > /home/user/_backups/E380-android-phone/userdata_20160126_223433.backup.dd-out.tar.gz
Worked for me. Then just used KDE's archive opener (Ark) to view the files, looks to have everything in there except keys and whatnot.

if you prefer a linux solution use this script it converts android backup to nandroid backup

Hello! Super-Developers, mega-programmers and smart hackers!
Nobody does not know how to open *. backup file?
No one can't help in this problem suffering millions of android/windows users?
You suggest them to install Unix/Linux system, - everybody to become hackers and programmers?!
maybe in the World exists GUI- programme to open *. backup file?
Someone can solve this problem of the century?

What do you expect. You are trying to edit a Linux based file. Not to mention a closed sourced compressed file.

There are free programs like OSFMount or DiskInternals Linux Reader for mounting (android) linux file system images on Windows. Also 7-Zip for Windows can extract files from linux file system images.
However, there is metadata like user identifier and group ownership, file permissions, SELinux context (user role type range) stored for each file, which gets lost once you have saved linux files to windows disk. Without this metadata you can not restore files to phone.
Regardless you can extract files in windows if you just care about pictures, music files etc. Maybe one day there is a developer who may write such a program no matter its useless for restoring complete user data to phone.
Regarding the userdata*.backup files (no cwm) this is a chinese feature not provided by google android open source project. Without source code its nearly impossible to analyze the checksum algorithm. You can not re-create a userdata*.backup file.
What you can do is unpacking it. make a guess. cut off the first 512 byte header of each file which is probably the checksum. then merge the files together. Now you have a file for further analysis. Its probably either a ext4 disk image or a (gz compressed) tarball archive. a disk image can be mounted as a new drive, metadata keeps preserved in this case. a tarball archive must extracted with gnu tar to linux file system. when extracting with 7-Zip you will lose metadata.
There is a risk of tarball archive is unheadered Tar, in this case 7-zip will not extract it. If your phone is encrypted, the disk image is probably encrypted disk image (thats where the hacker stuff starts).
If you want to remove the checksum in windows, there is a small problem. There is no such command. You can use a third party command line utility Trunc to try it. (truncate deletes only from tail)
Another way for Windows, you can use some linux utils with cygwin. I don't know exactly how to do it, but @Doc_cheilvenerdi.org released a Windows script Odinatrix which converts unheadered Tar to Ustar Tar. From this you can use some linux utils (i don't know if it works for converting backups, too)
1. unpack the Odinatrix-WINDOWS.zip file. copy the folder named "files" containing cygwin linux utils. rename the folder to bash (or any meaningful name)
2. create a new folder on Windows Desktop
3. move the backup files to <some folder>
4. open the Windows Command Prompt
goto Windows Start - Run...
type: %SystemRoot%\system32\cmd.exe - press OK
now type the following commands in Windows terminal console:
5. add bash folder to windows environment variable %PATH%
(example: PATH=%PATH%;C:\Program Files\bash)
Code:
PATH=%PATH%;<path to bash folder>
6. change directory and list backup files
Code:
cd %UserProfile%\Desktop\<some folder>
dir /a userdata*.backup*
7. cut off 512 byte header from each file using (cygwin) gnu "dd" linux util like @ektoric suggest in post #6.
do this for each file, skipping 512 bytes only (without unpacking). replace the wildcard * with <date>_<time>
Code:
dd if=userdata*.backup of=userdata*.part0 bs=512 skip=1
dd if=userdata*.backup1 of=userdata*.part1 bs=512 skip=1
dd if=userdata*.backup2 of=userdata*.part2 bs=512 skip=1
dd if=userdata*.backup3 of=userdata*.part3 bs=512 skip=1
8. merge the files with windows
Code:
copy /v /y userdata*.part0 /b + userdata*.part1 /b + userdata*.part2 /b + userdata*.part3 /b userdata*.img /b
9. try to mount the userdata*.img with OSFMount. if not working, try extracting with 7-zip.
Besides this linux is no hacker-os and just as easily operated as windows. You can boot a live distribution from usb-stick without installing.

Thank you for the answer!
Please comment next:

2) quote from Android Backup Extractor's README-TXT-instruction:
"Usage:-- Windows: very easy"?
Android Backup Extractor - -- sourceforge.net/projects/adbextractor/files
-sourceforge.net/projects/adbextractor/reviews?source=navbar
I tried to use Android Backup Extractor In WinXp SP3
but windows version of this app shows cygwin&some other files missing.
Do you know why it doesn't work?
I don't need to recover backup on its own place.
My target is to extract and open few files: photos, videos, documents...
Strangely 7zip also doesn't work. Thank you in advance!

adbextractor is for adb backups *.ab only (btw open source).
cygwin is a implementation of linux utils running in windows.
the above solution uses cygwin, did you try?

Thank you for first very detailed answer!
It seems that you have a remarkable grasp of this subject,
that's why I ask you to comment my previous post about video and Android Backup Extractor.
Your second post is not clear for me: adbextractor is only for *.ab files??
I have few files cygwin, is it a separate program??
I attempted to run file start.exe - windows version of Android Backup Extractor with those few cygwin files
but unsuccessful.
I read and test a lot, but The problem is still unsettled.

i came up two years ago with same question, how to unpack, and ended up with learning linux. i have uploaded a bash script, but i don't know if it works. i am not a developer and still learning, and nobody give feedback.
what is exactly file name of your backup? suffix *.ab or *.backup? these are completely different, don't mix up tools.
if you mean userdata_20180313_161000.backup files, please try mini tut above beginning 1.

It is classic aphorismic sentence!! I like it.
What's the bash script? for what goal? it is for Windows? If yes, I'll try it. give me the link.
my files are userdata_20100102_045926.backup, -=-=.backup1, 2, 3......
I'm not Englishman, "mini tut" is mini tutorial?
You have 100 posts and 25 thanks - super rate for notdeveloper.

the tool in video (adbextractor) can not unpack your backup. your backup is a splitted ext4 partition image. OSFMount can open ext4 partition images from Windows
bckp2cwm.sh script is basically doing the same steps like mini tutorial above. unfortunately it is for linux. main goal is convert userdata*.backup to cwm backup, but its paused in the middle (after unpacking, before repacking)
as windows user, all you need is a usb-stick. there is a tool unetbootin running in windows. it is a one-click-solution for downloading and copying any linux distribution to usb-stick. you can boot into linux from this usb-stick, for example ubuntu

Thank you very much for efficient advices!!!:highfive:
I'll try them in sequence.
although Linux is not my :angel:dream.

Solution for Windows
1. Download and install free hhd hex editor neo.
2. Open each of your .backup files, in select menu select range at 0 offset size 512 decimal, delete and save.
3. Use Windows copy command to join files as described in post#11 (Thanks to the author for free education).
4. Use any program that reads Linux disk image files. I used diskinternals (mount image from the drive menu first). Openext worked too.
This won't work on tar archives if I understand correctly. This took me days to figure out and only minutes to execute. No thanks to confusing android prompts while upgrading to a new OS.
