I have Acer Z530 with Lollipop 5.1, kernel 3.10.65+. I have the 16GB version, without external SD Card.
Today I have received an OTA update and after the restart all my data were gone as well as some 7GB of free space missing on the internal storage. When I connected using
adb I have found all my data in folder
/mnt/shell/emulated but the new data are being stored in
/mnt/shell/emulated/0. So far I was able to find that the 0 is the default directory of the owner user. It seems that this update added the multiuser support, but failed to transfer the data.
How can I easily restore my data? Can I just
mv everything to the 0 folder?
At this moment I'm
pulling the folder to my PC, to have a backup, but I would rather do it correctly.
