Recently, I am facing a crazy problem. I have only Linux machines and I have to make a backup of my mobile. How to do it, if a simple ‘adb backup’ doesn’t work? On the Android Developer, Options and USB Debugging are enabled. The adb backup -shared starts, download about 1-1.5GB from the mobile’s sd card which contains about 10-15GB, and stops working. There is no error message, but the backup file is corrupt. If I try to use adb backup with other options, then the backup length is 0 or 41 bytes. How can I backup my device? (Samsung’s SmartSwitch doesn’t work with wine 
)
Thanks & Regards
