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.
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/showthread.php?t=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!
I purchased a 5x for my wife so she can get on Project Fi. They said it was stuck boot looping, thinking I could solve the problem.
Here are the basics.
-Yes, I can get into boot loader (the menu of start, recovery, etc), but I can't get into TWRP. Tried flashing TWRP a few times and nothing. SkipSoft recognizes that its installed though.
-After bootlooping for awhile, it will load normally and work fine. However it wants to update to the newest version of android. I run the ota and back to bootlooping. It will show the android dude and say "error". Will eventually start bootlooping and then boot normally.
-I have flashed different stock versions. I tried the newest, the second to newest and the last M available. All will flash but continue the bootlooping.
Bootlooping can be anywhere from 1 minute to 10+.
The device will also first display something like, "Your device software can't be checked for corruptions. Please lock the bootloader"
But it'll show up whether the bootloader is locked or not.
The phone will freeze at some point. Whether right away or after 5 minutes. It freezes and then restarts and goes through the bootloop again.
So what else can/should I do? I've never dealt with Kernels but wondering if the last owner did something to them. Is there a way to flash stock kernels just incase or is this done when I flash a Google Factory Stock Image?
Would flashing a non-stock rom be a good idea?
Thanks
So I tried sideloading. I was able to get into the stock recovery. I tried wiping cache and data, then tried installing the newest stock rom.
Everything seemed to work. Then I had to restart. A message popped up after the same "Your device software can't be checked for corruptions. Please lock the bootloader". It had the title in blue stating "Encryption unsuccessful".
Then said, "Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible. To resume using your phone you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account."
Then there is a single button that says, "Reset Phone".
Problem still persists.
Help please...
Why did you bought a bootlooped phone?

When my Nexus 5x got into bootloop, I sent it to LG and they had to change the whole circuit. So yeah.
When you flash Google Factory Image, it flash the stock kernel.
If you have warranty, then send it to Google/LG. If you haven't got, then you're in problem. New motherboard needed, but it's expensive.
See the following thread for more info.

Hardware bootloop can't be fix by software.

Exactly. Everyone has either been able to get a replacement under warranty or was pretty much screwed if it was out of warranty.

A bootlooped phone for ever....
I recommend you will install kernel adiutor app after try rooting
I recommend you will install kernel adiutor app after try rooting
Almost I got no bootloop even no random reboot nexus 5x's state
So, long story short, I followed this tutorial: www . htcmania. com/showthread.php?t=1024045 (remove the spaces in w.h and .com) and it didn't go very well.
I flashed TWRP and SuperSU as told, using both download links (TWRP 2.8.7 & SuperSU 2.46), and my phone got stuck in a bootloop at LG bootloader unlocked logo. I recovered my phone by using LG Bridge and after that, when i tried to enter TWRP using the phone keys, it resulted in a factory data reset (no TWRP after recovery, didn't know that). I then followed the exact same steps but using what I thought was the lastest SuperSU archive (SR5-SuperSU-v2.82), flashed the archive and when finished, TWRP asked me to flash it again (so I did), then rebooted, passed LG bootloader unlocked logo, got into LG animation and... Bootloop again, so I recovered again with LG Bridge but I din't attempted to enter TWRP because this time i knew it wouldn't work and I ended it there, reinstalling all apps and configuring my phone as I had it before my unsuccessfull attempt. I continued using my phone as usual but sometimes, when I enter Pokemon Go, it says that it couldn't log in and that my phone's OS is not supported. As I said, the app does this sometimes whenever it wants, so I researched a bit and turns out it doesn't work with rooted android devices (I didn't know that). I knew my root attempt failed so I downloaded and app called Root Checker and checked: Root status-Not rooted; SafetyNet Status-Failed. I don't know what should I do know, last time I rooted my phone was a Sony Xperia XL and it wasn't so tricky.
I asked for advice in the forum and got no answer, so here I am, hoping for a solution. What I want is to have a permanent custom recovery, a rooted device and to have SafetyNet status passed. Any ideas, hints or whatever? Please, help
I've had Google phones for years now, including previous Pixel, but I just got an XL 2 yesterday and I'm regretting it.
It's Google unlocked and running June's latest image. I've experienced various app crashing on stock, and random reboots.
Then there's the rooting and flashing. I unlocked the bootloader and installed the most recent, twrp (the one verified to work on xda for roms) but can't flash anything.
My twrp either hangs on the twrp start screen, or when it does load, the touch screen doesn't work. When I can get it going, every rom I flash gives me an error on the second step. I'm flashing on slot B by the way, that's what boots up when I boot to twrp.
Lastly, I am unlocked both for flashing and flashing_critical thru adb, so I'm at a loss and seriously confused.
When I FIRST unlocked everything, I was able to flash Nitrogen rom but I got stuck at the rom splash screen.
Tldr:
-What is the Correct install method/sequence for roms?
-do the slots matter?
-is random reboots and app crashing on stock a sign of a hardware issue?
I haven't installed a custom ROM on my P2XL, so I'm running rooted stock. Anyway, for rooted stock, this is what I did.
Entered bootloader mode.
Booted into recovery using the command "fastboot boot recovery.img", where "recovery.img" is the TWRP recovery iteslf. In my case, I renamed it "taimen.img".
Flashed the TWRP installer zip needed for the P2XL (Required if intending to replace the stock recovery).
Rebooted into recovery.
Flashed a custom kernel (Recommended - resolves touch issues in TWRP).
Flashed Magisk.
6. Rebooted.
If installing a custom ROM, flash it prior to the custom kernel. Slots only matter if running stock. Random reboots and app crashes are not signs of a hardware issue.

Ya know my friend, after our conversation yesterday, and your questions in the nitrogen thread, and now random reboots and app crashes, I think it's time to consider a factory reset. You shouldn't be having those problems on a stock setup. If that's not successful, then I would definitely consider an RMA. Just my 2 cents worth :good:
I agree. I got it used tho which is an issue.

Just so you know, I got the rom to flash finally, but it's stuck at the rom splash screen during first boot. I'm going to leave it and hope it eventually boots up.

If it doesn't after 5 minutes, do a hard restart with the power button. If that doesn't work, then reboot to twrp and flash the rom and twrp installer zip again.
Ok cool thanks. I relocked bootloader last night and went back to stock. Unlocked it all this morning from my work computer and different unlock app. So here's hoping.

I finally got everything to work. My vendor image is a mismatch but I could just flash junes and be done with it, right?

What did you do to get it to work? You could just flash the June vendor.img to both slots. If you keep getting a vendor mismatch, probably nothing to worry about according to the Dev of nitrogen.
Different machine, cable and unlocking tool.
But I went to bone stock with locked bootloader, then flashed the newest twrp with the newest all in one tool. Was on slot A so wiped everything and flashed rom plus twrp again. I rebooted system to slot B, but then it just hung at the rom splash screen.
So I did it all over on slot A, ignored the "no os installed" message and booted anyway. Then it fired up. Rebooting into twrp from there took me to B, which is where I need to be for an image file or root.
So yea, thanks for the help.
I'm having this issue also. I tried flashing nitrogen, it hung. I tried to go back with factory reset Img and nothing happens in adb. Flashed the may img and it wouldn't boot all the way up. Now I'm stuck in bootloader trying to figure this all out. Seems like nothing in doing is working. I can get recovery to boot, but no files inside so idk. Tried to sideloadb nitrogen, but it said adb out of date for device when sdk is fully updated.

You didn't mention the out of date message in your other post, but uninstall SDK and then download the stand-alone adb/fastboot binaries from May of this year. Dump that in a folder (eg. c:\adb) and put that folder in your path statement. Manually flash the full factory image without modifying flash-all.bat. Post your screeen if you have any errors. :good:

Google knows the date the phone was purchased based on imei number and honors their warranty by date, not owner. Unless it was blacklisted.

Thanks. I might try to take advantage.
I recently dug out my old G4 to see if I can repurpose it for anything or just have it as a back up.
It's an H815 European variant with unlocked bootloader. When I last used it I had it running a custom ROM but when I got a new phone I wiped it somehow with TWRP (this is a few years ago so I can't remember).
Now whenever I turn it on, it boots into TWRP. If from TWRP I choose reboot to system, it boots to TWRP.
I tried to install a ROM but it wouldn't, giving the error "this ROM is for P1,G4,H815 (or something like that), your device is .".
So, I edited the ROM metadata and took out the device requirements and it installed fine, as did GAPPs & SuperSU, but still it only boots to TWRP. I've flashed bootloaders, kernels, god knows what else, but it only boots to TWRP. That's it.
I also tried to return it to stock using these: https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848 but it had errors connecting to servers and never installed anything.
I'm aware that I won't be able to recover anything on the device and that's fine! I just want to boot it with ANY ROM, and I'd be grateful for any help! Thanks!

Try latest rom and one by one different rom. It's rom related issue. Don't worry, it'll be okay.
