Hey everyone,
I dreaded this ever since I got my H811 G4 but I think I got the bootloop bug. I was on 20o for the longest time rooted. I just recently unrooted via Superuser and then I updated to 20p using LG Bridge last night. I was browsing Instagram earlier today when my phone suddenly crashed and rebooted. It then brought me to the LG boot logo, then Tmobile and would sometimes reboot from there or go to my lock screen, work for a few seconds, and then reboot. Has anyone found a fix or something temporary so I can back up my data and possibly downgrade back to 20o? Or does anyone know of a way where I can install TWRP from download mode possibly since I can't used ADB?

Dear friends,
My optimus 2x is giving me hard times from the very first step of rooting and installing custom firmwares.
My Optimus is from FIDO Canada. When I bought it, it had stock 2.3 V25H in it. I rooted it via AIO Toolkit and then the bad time began.
When I restarted after rooting, LG logo appeared for 3 seconds and then a black screen forever. Restarted again and again but nothing happened.
Then I changed bootloader to ICS and flashed Domination via recovery, restarted and the device never booted again even in recovery.
Downloaded V30a kdz for fido via lg and smart flashed it. Device started normally and welcome screen appeared, but touch wasn't working at all.
Thought it's a kernel problem, flashed different kernels and bootloaders and nothing happened.
Please help me ASAP as I am dying to use my phone.
Regards
First, my phone was completely stock and not rooted. I wanted a fresh start so i TOT'ed back to 11a (i couldn't get the KDZ method to work). All of the OTA's installed fine and after downloading and installing the Lolipop update, the phone got stuck at the LG screen and stayed there for 30 minutes. I powered off the phone and did a factory reset. Still stuck at the LG screen. I was able to get back into download mode and start over. Has anyone had any issue like this before? Any help would be greatly appreciated. Thanks!
So I've had my phone rooted for a while on 26A using Xdabbeb's VS980 2.20. Worked well, but I started having some issues. In trying to fix those issues, I backed everything up and used this guide to revert back to stock 11A (TOT method).
Reverting back to stock worked well. Verizon started pushing OTA's (which I haven't had for a very long time). I believe I got up to 29A. However, Verizon pushed one more OTA, phone rebooted, installed step 1/2, and then step 2/2.
This is where I'm stuck. After finishing step 2/2, the phone rebooted, showed the LG logo and stopped.
I can get in to stock recovery mode. The green android flashes on screen briefly, restarts, but it get's stuck on the LG logo when it restarts.
Download modes doesn't install drivers on PC to show as a COM port. LG Flash Tool can't find it when I try to flash anything on it.
Any ideas on what to try next? I'm completely lost on where to go from here. Any help would be extremely appreciated.
TL;DR: Stock LG G2 phone is stuck on LG logo after OTA update to 39A. Recovery isn't working. Download mode isn't working.

Unfortunately, no. My phone is currently on it's way to LG to see what they can do with it. I won't know any more until late next week .
Got the word back from the repair department. The LCD screen was bad or connector (pretty much knew that). Not sure if they got it to turn on, but they were going to charge $150 to repair/refurbish it (90 day warranty). I called to get more information but the person I talked to didn't seem to know any answers to my questions, so I gave up.
I opted to buy a new LG G2 from eBay for $195 (1 year warranty).
When I get the old phone back, I'll see if it boots.
My phones stucks at bootloop after ota update, so I decided to flash kdz via LGUP. (v. 1.14.0.3). Then I tried it two times and I have no errors both of pc and phone, but phone stuck at lg logo(one time T-Mobile logo appears and suddenly rebooted itself). Also, the second time I get some unexpected things like the phone says it is h81120o but LGUP recognize it as h81120i.
Anyone has this problem? Can I flash again h81120i?
Edit:Thanks for everyone who helped me but I am so bored to deal with it. So I give up to try and I will use my old phone. (All photos are removed by me)
i think its normal.. it says 20i cause it was on 20i.. once you flash it. hte next time it would say 20o..
as for the reboots i think you have the infamous bootloop.. so it must be sent to LG for repair.. sorry.
noooooooooooo dont flash 20i
20i its antirollback V2
20o its V3 if you do itll brick phone.. so you stuck on 20o...
I'm not in U.S. It was bought by my friend when he was in U.S. So, No option to send it to LG. I talk with lg service center, they says I have warranty but they need a physical address.
My phone optimizing 55 apps when first boot then finishing boot and then it reboots and stucks at T-Mobile screen. Just for once it ask for first setup configuration but it shutdown because of my battery is too low. After that it doesn't boot any more. Do you have any suggestions to back it live? I have download mode and factory reset and pc can recognize the phone. But this is first time I deal with this issue.
<deleted>-Please look for photos what I have first time it boot normally after factory data reset.</deleted>
best thing is to have it repair... but if you cant.. then no.. theres a TOT file that disbles big cores .. but only for h815..
Hi guys,
So I had a stock T-Mobile LG G4 H811 that I had unlocked and booted into twrp version 3.1.1-1-g4. I wasn't able to actually flash recovery of this .img becuase of a write failure. So I booted into it instead and then installed it from within twrp into the recovery partition. The actual stock software was the ORIGINAL original, which I think was android 5.1.1
From there, I cleared the cache and delvik cache and installed the G4-H811-10N-xTreme-2.0 Rom. Now, I can't boot into recovery mode anymore, and all I get is the bootloop.. but it's not dead yet because it's a software issue on my part and not a hardware failure.
Any advice on how to get it to recovery mode or at least so I can boot into twrp somehow to try and get this fixed? I tried Power+Volume Down and then let go a sec and Power+Vol Down again and it won't work at all. Just goes straight to bootloop.
Thanks in advance.. I know I screwed up somewhere.. just so many loopholes, it's easy to miss.
Best,
Johnnie
Got somewhere, still broke
Well, somehow I managed to boot into recovery mode only 1 time and installed the stock Tmobile rom. It installed, but now I get a white T-Mobile screen on boot up and it stays there. I tried using the LG Flash Tool 2014 and the stock T-Mobile H811 10N firmware for T-Mobile, but all I get is connection to server errors and the software won't install to the phone over download mode. Anyone else have this problem? I've been trying to figure this stupid thing out for 6 hours. Also, I'm wondering if installing the stock firmware caused the original recovery partition to go back to stock too which is the reason I'm no longer able to boot into recovery mode? It just doesn't recognize it. Power+vol down and then vol down doesn't do anything.
When using the LG Flash Tool 2014, all I get is Connection to Server Failed, Try again. So I do, and nothing. It fails at 9%
Thanks.
