I think I didn't explain myself well in the first post. I have a data.tar and system.tar from the backup on my computer:
data: adb/, anr/, app/, app-asec/, app-lib/, app-private/, audio/, backup/, bugreports, dalvik-cache/, data/, dontpanic/, drm/, fota/, hostapd/, local/, lost+found/, mediadrm/, misc/, nfc/, property/, radio/, resource-cache/, security/, shared/, system/, time/, tombstones/, user/
system: app/, bin/, etc/, fonts/, framework/, lib/, lost+found/, media/, priv-app/, tts/, usr/, vendor/, xbin/, addon.d/, recovery-from-boot.p, build.prop
I'd like to know where to look for the FreeOTP files containing the keys, so I can move them to the phone.
