Hello all,
I have a LG G2 Sprint Variant. I have rooted my phone using the ioroot method. I have TWRP v2.6.3.2
I decided today to check out a couple of the custom roms d3rp and icerom. When I flashed the roms each time I was presented with the LG screen and then below the LG it just said "Security Error" and turned off. I can still boot into recovery and I just flashed my backup and I'm fine.
I need to know why I'm getting the security error and how to get past it.
I have seen the security error on the forum, but each time that person couldn't get into recovery and seemed to have to use the LG tools to flash back to stock. My situation isn't quite so drastic, but still aggravating.
Thanks for the help.

Hi guys, I got my LG G2 a few months ago and it was my first android phone. Since I always jailbroke my apple devices I decided to root my lg g2. Everything worked fine until last week when I was prompted to install a software update. I thought this might mess up the phone since it was rooted so I postponed it until later in the day to give me time to research, but I forgot to postpone the update again and it went through at the scheduled time. Now when I turn my phone on, the lg logo is displayed, and then I get a boot certification verify error. I don't really know what that means but I can't do anything, no recovery, no download mode. I started to follow this tutorial but am stuck at what files to download. I do not know if I have the 10b, 11a, or 12b variant, and I can't find a way to check it without turning the phone on, which I can't do. I'm really lost at what to do at this point, I can't follow the only guide that might fix my phone. Is there another way to solve this issue or find which variant I have? Would verizon accept it back to fix or replace it since it's been rooted? I've read some people saying they unrooted their phone and then returned it to the carrier, is it possible to do that in my situation? I really need some help guys.
TBH: I would call Verizon, and tell them the phone was bricked by the update- hope they don't notice it was rooted when they warranty it. Problem is, if they do you get charged full amount for phone. I'd consider if you have insurance to just claim it on insurance.
try download lg support tool from lg website http://www.lg.com/uk/support/software-manuals
plug the device and wait for the software to recognize ur version.
I downloaded and installed it, but it won't recognize by phone. I have installed the drivers for it
ok.
try to follow this guide http://forum.xda-developers.com/showthread.php?t=2681089
and the files download from here:http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware/10B_Partitions
lets try this virsion and see what happend..
download the 10B zip file and the dll file too http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware
now it doesn't boot at all, not even to the lg logo. Additionally the partitions don't show up in ubuntu any more. I guess i'm completely screwed now?
Hey all,
Having a small issue with my Verizon LG G2.
When I first got it on launch, I rooted it, installed loki (to bypass the locked boot loader) and have been running custom ROMs.
This is the way I ahve been running it since, on 12B, with loki and CM11.
Before I installed custom roms I did a image backup using Clockwork.
Yesterday I bought a Droid Turbo, so it was time to restore the G2 in preparation for sale.
I attempted to restore my original backup of the stock image, but it failed (stating something about an inability to restore/system, resulting in a soft bricked phone.
I fixed this by downloading the LG Flash tool, and the stock 24A .kdz image, putting the phone in download mode and flashing it.
The LG flash tool seemed a bit buggy, complaining about not finding servers, but eventually flashed the phone with the .kdz.
Everything seems to have worked well. Root is gone, clockwork is gone, (and I assume loki is gone as well, but I can't tell) but now I can not do the latest OTA updates, and am stuck on 24A.
It's not that it downloads the OTA, and then fails to install it, but rather it complains that it is unable to download the updates at all.
I was thinking this might have something to do with the fact that the CDMA radio is now unactivated (since I got a new phone) and it somehow needs to verify with the Verizon network prior to downloading, so I grabbed a working SIM and popped it it in. Even with 4G via the SIM, the OTA downloads don't succeed.
Does the CDMA radio need to be activated in order for a phone to receive OTA updates? If not, I ahve something else wrong going on, and would appreciate any suggestions regarding fixing it.
The plan was to sell the LG G2 to pay for my Droid Turbo upgrade, but I don't want to sell the phone to someone if I think it may be having issues.
I would appreciate any thoughts and suggestions from you guys!
Hello everyone, I have the Verizon LG G2 and it thinks it's a different g2. I have edited the .tot's to other device models and it still won't work. I have followed many threads and none are working for me. I also did try the .kdz method which kept getting stuck at 2%. I also do not have twrp.... My question is is there a way to install twrp right from download mode to try to flash the right software to get it working agian? Or does somebody think they can help me figure out the problem with the download mode restore?
Hello i have a problem with a friends LG G2 I flashed it lolipop 5.1 and then i wiped the whole internal storage clean and installed new firmware on it i tried flashing 4.4 the second time then the phone did not boot up and the screen was stuck to an error message cant quite remember it.
Anyway my friend sent it to lg and they said to him that the phone was double flashed and it could not be fixed... I need to know if i can recover the phone and if so detailed steps if possible.
Thank you very much (The phone has access to TWRP recovery.)
Please guys it is very important i need help with the matter
It can be unbricked. Your problem was probably flashing wrong bootstack since you got security boot error.
First, if you can get into download mode, do tot/kdz. There is guide here on xda

[H918] Successful root/fastboot unlock from 10J -> No roms are flashed successfully
Hi folks, wanted to share my current state of affairs with trying (and failing) to install a new rom on my LG V2O. Here's the order of events
Received brand new sealed-in-box LG V20 from T-Mobile from a third party seller that came in firmware 10J
Followed all directions to successfully perform dirtycow unlock
Installed TWRP (3.0.2-1)
Backed up, but mistakenly deleted the backup after trying to install Megarom in an attempt to do a clean flash
.zip flashed correctly, but hits boot loop upon reaching LG screen (even after waiting 20+ minutes on first boot). T-mobile screen never pops up
Can access TWRP still and ADB commands
Basically now, I've tried looking at as many H918 rom threads as I could but every single rom I try either: never completes flashing OR if it does complete flashing, the device never boots (either bootloop or stuck on the LG screen). I've never seen the device get past the LG screen for any reason. I am desperate for help on this matter as I have royally screwed up trying to provide a nice gift for my partner but was apparently way in over my head with trying to get a fresh rom on this thing.
Can anyone provide assistance as to how I can roll back to a stock rom? I'd be willing to give up root/recovery. All of this was spawned from wanting to be able to unlock the carrier but I have decided I'll just pay for the sim-unlock service if I can get this back to stock. Would be willing to provide some PayPal cash for someone who can help me out with this matter.
Flash to 10j kdz firmware located in the thread with all the firmwares. You`ll need lgup to flash it.
