Hi, I am trying to back up my user data before giving Android 7 a try, but currently stuck on OpenOS 18.04.3 because TWRP is giving me an error when I try to backup data.
The list of partitions shows Data as 0MB in size. Selecting only it and swiping to backup leaves multiple errors on the console mostly saying:
Failed to mount ‘/data’ (Invalid argument)
and one saying:
Failed to mount storage
amongst other lines before it tries to start the backup, then aborts and cleans the backup folder.
What can I do to get this to backup correctly, or am I doomed to risk losing data with an ‘upgrade’?
P.S. is the flashlight reboot workaround nonsense still a thing or fixed yet?
