i got a backup.ab file with password. I'am looking for how to open it for 1 month but i still couldnt open it. I really need help can anyone tell me how can i open it please explain it with step-step
backup.ab files are usually created by the command
adb backup. This answer is only for backup files that has been created by
adb backup. It will not work for other backup types.
Extracting an Android adb Backup file is pretty simple. You just need Android Backup Extractor, a Java program that does everything for you.
Just download the latest
abe.jar release. As it is Java based you also need a Java Runtime. Oracle Java is no longer free in all usage scenarios, therefore I recommend OpenJDK from Eclipse foundation. But any other Java 11 or 17 JRE or JDK is also fine (abe requires Java 11+).
To convert your Android Backup file
backup.ab to a tar execute
java -jar abe.jar unpack backup.ab
It will create a file
backup.tar which you can open using an ZIP tool of your choice (e.g. 7-Zip).
