My Lenovo Yoga Tab 3 isn't rebooting

I'm suddenly getting this mesg. on screen, 'Encryption unsucessful' and there's an option for RESET TABLET, which isn't working/resetting even after clicking the same.


I did try hard resetting with the power and volume-up rocker buttons, but there're also some errors messages as:

Supported API: 3

E:failed to mount block devices /dev/block/bootdevice/by-name/cache

E:failed to mount /cache (Invalid argument)


The Wipe Cache Partition, Wipe data/factory reset, Mount/system, etc. options  aren't working.


Kindly help, as I'm staying in a very remote mountanous location with pretty bad climate and the nearest city is a day far..

Help me out!

Re: My Lenovo Yoga Tab 3 isn't rebooting

I have a quite similar problem, and the recovery mode is not working properly. After trying to do a factory reset the screen just appears blank and reboots back to recovery but all those errors as you showed appear again but nothing happens. Tablet itself is stuck in boot logo if not entered in Recovery Mode. Fastboot is not working either. Someone please help!!
