Question [Q] Secure booting Error! after official update - TWRP installed

This morning my LG V500 offered a software update. I started the update process without thinking. When the tablet restarted to install the update I saw the LG logo and then was greeted with the following message on the screen:

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 v2.6.3.1 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?

What all have you tried?

A simple shut down and re-start possibly could fix it. Just a guess, but worth a try. You should update to TWRP's latest also.
Asus Transformer TF101 10.1"
(Rooted - KitKat 4.4.2_23 by TimU)

LG G Pad 8.3
(Rooted) - [KK][4.4.4][LINARO/SABERMOD] CyanogenMod 11 nightly
(Different nightly if the changes look interesting, but always
a nightly upped/optimized by Infected, if possible)
Or anything else up is possible also...

Unhappy same problem here

Same problem as original poster, just I was on 2.7.0.0 TWRP. Upgraded to 2.7.0.1 - same problem.

Restored from previous TWRP backup - same problem. Installed custom ROM - SAME PROBLEM!

Out of options at this point. HELP!

Ever since I rooted I've had that. In fact if you watch Ytube's video about rooting an LG G Tab, you will see guy say "Don't know what that is - but all works.

Now on a transformer101 I didn't see that.

But frankly, so what? You don't go to recovery that much -- that is the only time it shows.

Cal-123 - issue here is not just information message, but boot loop. No matter what I tried - it goes to main TWRP screen.

Looks like solution is here: http://forum.xda-developers.com/show...2622034&page=2 , will post update when done

I did a recovery with the LG tools. All my data was backed up so it wasn't a huge deal for me. I can't even remember why I rooted my GPad in the first place.

I Hope you worked things out, but your problem possibly could be that some Roms have a built-in recovery option - by that, I mean instead of just rebooting, they will boot into recovery. You might ck. that to see if it is enabled. This "SlimKat" ROM has the feature.

Good luck!

Cal-123, thanks, I was restoring backup done with TWRP - same problem (rebooting to TWRP screen, not to system). Still don't know root cause, but problem was resolved by flashing stock KK update by using B2CApp. Obviously root is gone, so back to reading forum

At least can play Deer Hunter again

Cheers!
