Good Day everyone
I am in desperate need for some help please, i managed to brick my LG G2, and need help unbricking it
I have the D802 International model.
The story so far, it had Cloudy G2 2.1 Rom on, wanted to update it to, Cloudy G2 3.3 , followed the guide on Blogspot, when, you search for "kevin with tech cloudy G2 3.3" on Google
Wiped the partitions via TWRP 2.7, as stated in the video (everything except internal storage), and then installed the KK-D802 bootloader.
After i rebooted, my G2 did not come boot again, it will go on with the boot logo and the words: "Boot certification verify" Secure booting error. will appear for about 2 seconds then just goes black.
Whenever i try to plug in via USB cable, it will detect multiple new drives in windows and accept me to "Do you want to format". in the device manager i can see device being detected as "QHSUSB_BULK"
My phone is rooted as well.
Some sites recommend using a linux way, but i have been through countless forums, and not sure which way is the right
Please please i need some help unbricking it, and willing to donate to the successful user advice / tutorial of unbricking it.
Thanks for reading and in advance.

Had the exact same issue, I believe it's caused by corrupting the internal memory (multiple causes for this).
Don't freak just follow http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 (there's a video guide at the bottom, but it's pretty straight forward).
After that follow http://forum.xda-developers.com/showthread.php?t=2432476 to get it back to stock and work from there.
Good Day everyone
Thanks for all the advice and help, wanted to update the thread to solved, but things went a bit hectic at work during the week.
Anyways managed to get my phone working again, and restored to original state(thank God).
Basically followed a guide i found on Youtube, used the LG Flash Tool 2014 to flash back to Kit Kat stock, and then from there i rooted and used Auto_rec.
Found a guide on Reddit for Cloudy 2.2 install, flashed correct KK-Bootloader, and restored my Nandroid backup (which strangely at first did not work when restored via TWRP on stock Kit Kat, got the same Secure boot error)
Restored only data and system (everything except the boot) and my phone was back to it's original state.
Hope this helps anyone in the same situation.
PS: I was stuck in some boot loops, so had to format my internal memory as well.
Peace

Hello, so I am having a bit of a crisis. LEt me start by giving a brief description of what has been done to the phone...
LG G2 ATT (d800) running 4.4.2 OTA.
Was rooted AFTER the OTA update.
I tried to install a custom recovery first by using ROM Manager to install from the phone itself. The stock recovery was intact as of this point, as ROM manager just flat didn't work. My next move was to follow the thread found here...http://theunlockr.com/2013/11/03/fla...ersions-video/
That is were I started seeing issues. The phone no longer was able to boot into recovery at all. I received the "secure boot error". So I took another approach.
I followed the post found here... http://forum.xda-developers.com/show....php?t=2582142
This is where I am now. The phone is stuck on the LG boot screen. I suspect my problem began when I used the files found on that post for the d802 instead of my d800. However, ubuntu will not recognize my phone now. Download mode will not help, it appears.
I think the solution may lie in the post found here... http://forum.xda-developers.com/show....php?t=2432476
The issue I am seeing with this is that I cannot see the COM ports within device manager to set the correct port. I will post in that thread as well, just to reach as many people as I possibly can.
WHAT DO I DO.
Thank you for your future help.
Hello everyone I need some help with my G2 its the rogers D803, First off I'm kinda a noob when it comes to flashing roms, this is my third G2 I've owned, i bought it off kijiji and its been nothing but trouble, my LTE wouldn't work and I couldn't update it to 4.4, The ota wouldn't work cause the device was not resisted. I tried to update with the LG support tool, when i would connect the device it would say update found then all of a sudden it would say your device is up to date. So i decided I would root it and flash a custom rom. I used TWRP a flashed Mahdi Rom and it worked great. Now here is where I messed up, I decided to try another rom, went into recovery and did my wipe but i accidentally wiped the system along with all the roms and zips I had on the internal storage. now its stuck i n a boot loop, I'm still able to get into twrp and also can get into download mode. my problem is I'm unable to mount the device to get my roms or even my backup folder back onto the device. when i plug the phone in i cant get the drivers to install , ive tried using ADB but my device doesn't show up on there. it does show up on the lg support tool when i put it into download mode. If anyone can help me out it would be much much appreciated. sorry for the wall of text but I'm trying to give as much details as possible.

It was getting stuck on the Lg logo but i was still able to boot into twrp. but good news I just figured it out. I downloaded Koush universal adb driver and was able to sideload a new rom.
Hello all,
Today I read a lot of posts here about rooting my phone because I was done with the stock UI.
I went for it and now I think I made a mistake, I would like your help. I read some similair posts, but I cant find a true solution for my problem.
My goal is to run CM 11, I have a stock LG 802 config with 4.2.2.
My steps were as followed:
- I used towelroot v3 wich was succesful
- I installed and ran D802 autorec (wich i guess was a bad idea). I got to recovery mode and I wanted to back up first.
- I made a back up of boot and system
- After the back up, I had to reboot
- NOW its stuck in a boot sequence to nothing. Just a light green and blue. I get the logo and I can get in the stock recovery it seems. Should I reset to factory settings?? Is that data still present?
I hope I can go from there, but after my major fail Im afraid to try it.
Thanks a lot in advance!
Update
I can get into download mode and LG Support Tool finds a phone, but the specs do not match and the update states that there is not any update available, wich there is.
When I get into recovery mode I can get into TWRP and I should be able to continu the process with flashing and wiping. The CM mod and Gapps are already on the internal memory. But I am really afraid.
For the record I did not flash or wipe anything yet, except for running Autorec and rebooting after prompt.
The real question for me is (I guess), is Autorec really unsupported with 4.2.2?
I would like to go on with the process, but I also would like to go back stock if needed in the future (hence the recovery back up I made with TWRP before the bootloop.)
Thanks again for any help what so ever
first i wanna say that this is my first time trying this and after a lot of research i thought i knew what i was getting into but now i feel completely lost. earlier today I rooted my phone using one click root then installed twrp using auto rec. auto rec seemed to work fine and i clicked open in recovery just to see if it worked. twrp opened no problem but when i went to boot the system back up i started getting security error messages under the LG logo. i tried getting it to boot again after formatting and now its just stuck on the LG logo and not doing anything at all. im almost positive i have a d800 version and pretty sure that i used the right autorec file. i was running 5.0.2 instead of kit kat so not sure if that had something to do with it. please help me out anyway you can, i really need to get my phone working again for work and not sure what to do. i tried searching for an answer but had trouble figuring out what to do.
Yes definetely it has something to do with it. Because autorec uses kitkat kernel. You just have to flash lollipop kernel and you're good to go.

Flash stock firmware with KDZ (Lg Flash Tool) there are a lot of tutorials here on xda.
Good luck.
I'm in the middle of the TOT method right now to get it back to stock firmware, seems to be working. so now if i want to start over and root/get twrp on my phone any suggestions on the best method? i've read a lot of different ways to do it and not quite sure what would be best. sorry if this seems like an easy find, i just dont want to run into this mess again ha.
Lg g2 wont turn on after installing autorec
I have tried to install auto rec on my g2(4.4.2). And now the wont boot and not even going to download mode. When i connected the phone to the computer phone is not getting detected. In the device manager it is shown as android phone=> android bootloader interface. when i try to turnon the phone, the screen just displays some vertical and horizontal lines on left side of the screen. Please help !!!
(I CAN GET INTO TWRP AND DOWNLOAD MODE) T-Mobile D801 (This was my previous phone that i had rooted before) My dads LG G2 was having issues with the touchscreen on CM so i decided to flash the stock ROM but i guess i might have skipped a few steps and after flashing i got :boot certification verify, secure booting error! and cause: boot certification verify. after that i tried flashing a backup but i got the same thing. My friend told me to wipe all the files so i did and that's what point i am on now. I can still boot into recovery but have no idea what to do further, i tried to following one of the guides on here (forgot link sorryz) but once i got to one of the steps where i plug my phone in my PC would recognize it as a bunch of drives (tried this on a different PC as well) WILL REALLY APPRECIATE THE HELP GUYS!

if you can enter download mode then just flash stock friemware. using TOT or KDZ. thatll fix it. the boot error is when you mess with the bootloader. like you instal wrong bootloader for rom..
try it again.. i had same all i did was go back to stock.
i cant flash anything though since any PC will recognize my phone as a bunch of drives so i cant get the stock firmware
