I need to backup app data (some games) from Android 4.1.1 (Xiaomi Mi2S) and than restore them on Android 9 (Xiaomi Mi9T). I have tried using
adb backup, but current version is not compatible with Android 4.1.1 (creates 41 bytes file). When I tried using older ADB (as suggested here: link), I couldn't get
adb devices to recognize my device.
Is there any way to backup app data without using
adb backup? I have access to root on Android 4.1.1 but not on the new Android 9.0
