Secure booting Error!
Cause : Device Unlock!, so Boot Success!!!
...after which I end up at the TWRP screen.
This happens every time I restart the tablet.
Before the update, I had Android 4.2.2 installed with kernel v3.4.0. I had installed TWRP v188.8.131.52 to root my phone. I have NO custom ROMs installed.
I'd prefer not to restart from scratch, but I guess that I can do a Factory Reset, Advanced Wipe or Format Data from TWRP to restore functionality to my tablet.
Any ideas on how I can avoid losing all my customizations?
