Last night i restarted my tablet, but continually drops into recovery mode.
I have also been in a menu which recommends 'erase app data' to boot into safe mode, in order to backup data, prior to factory reset. So i have erased app data, but now just enters recovery menu.
I'm not sure i have any debug/developer settings switched on this device, as only flashed roms on phones long time in the past, not this tablet.
So can anyone guide me to get it into safe mode to take copy of user data partitions?
Have dabbled with some adb but doesnt recognise any devices, so wondering if being blocked by some security.
Thanks in advance
John
