I am trying to back up an Android device using ADB.
However adb backup -all gives me this error: adb: unable to connect for backup why am I getting this error?
I know that some device is asking for permission to do this, it asks if you want to allow the computer to backup, but my device does not work.
I am developing Android devices, I don’t care about ruining it - so you can tell me how I can let my device ask for permission or even how I can fix this problem.
I can use adb shell and it works fine, and so adb pull/push I need a backup file, so I really need an adb backup.
Is there any other way to make an image of the entire Android OS, applications and settings? (Best of all, if you can point me in the direction in which I can find a solution to the problem that I mentioned, but I am open to other ideas.)
Thanks!
