Hoping someone can help me here.
My wife has a G3 that started acting up back in September or so. It would randomly turn off and reboot, usually while not even touching it. Did some looking around and found that the Facebook Messenger app could cause some instability. Removed the app, all was good for a couple of weeks before it started again. This time, we backed everything up, did a factory reset, all was good for about a week. Reboots started again so I did a hard reset from Recovery. Booted up, everything was good again for about a week again before the reboots started up. The wife ended up giving up on it and went back to her Galaxy S3.
I've been messing around with it today. Phone has been stuck in a boot loop at the LG logo. Battery is fully charged. I followed some guides and downloaded the V10c stock firmware TOT file, dated June 20th, 2014 and LGD851_20140611_LGFLASHv160.dll and loaded them up into LGFlashTool v1.8.1. Installed fresh LG drivers on my Win7 PC, followed the flashing instructions to the letter using a USB 2.0 port (as I read somewhere that 3.0 ports have caused issues on some devices). Everything flashes 100%, flash tool reads complete, phone shows a big 3 on the screen with a blue background. Unplug and reboot the device and it's right back to a boot loop at the LG logo.
Now at one point, during the flashing process, it would boot into LG MiniOS 3.1 and I was able to choose an option (chose Normal Boot) and it would go back into the boot loop. Also, I connected it to my Ubuntu machine just to see what would happen and I received an error "Unable to mount LGE Android Phone. Unable to open MTP device", which makes sense. However, the phone itself would get to the T-Mobile logo and briefly jump into the initial setup of the phone before jumping back to the LG logo and starting over again. Connecting back to my Win7 machine, it just boot loops unless I have the flash tool running. Not having USB connected, it just boot loops.
I'm at a loss here. I can usually muddle my way through these kind of things but this one has me completely stumped. Ordinarily, I wouldn't worry much about this but she's wanting to get a new phone through T-Mobile's JUMP program and we can't do that if the phone won't even boot.
Any help would be appreciated.

Good afternoon, my recommendation is that flashes with lg flash tool 2015. All you need is your phone updated driver installed on your pc. Further, you need to download the KDZ (firmware of your stock rom) corresponding to your model. Look at the XDA thread as do or YouTube. If you need more help, you can consult here.

IIRC, he's talking about going back to the latest stock firmware available from LG and flashing with with @quangnhut123's flash tool.
Thanks for both of your help on this. I actually had given up on the phone for a while. The last time I flashed, it was allowing me to get into the first time setup but wouldn't let me complete setup before rebooting. So I ordered a new battery and everything is working like it's brand new. Thanks again!

Hi all,
I've done a bit of a search on this problem but everyone I stumble across is slightly different and unique to them.
So I was on rooted stock kitkat, (v10h I believe from memory) received the lollipop OTA but held out for a while.
Decided to go ahead, backed everything up and plugged it into LG PC Suite.
Started off with a Restore Upgrade Errors to attempt to unroot and get back to stock before trying to v20f update. But I never got that far. It popped up saying update failed with an option to retry, but that also failed and then just got stuck at 0%.
So my situation now:
Turning the phone on goes straight to the Firmware Update screen. Holding down either of the volume buttons at boot makes no difference.
It is recognised by my computer, but not as an actual device. Just that something has been plugged in somewhere (it beeps). LG PC Suite no longer recognises the phone.
What are my options?
Thanks all,
Update
I left it plugged into the PC stuck in "Firmware Update" screen.
LG PC Suite did not identify and connect to the device, so the possibility of a firmware upgrade was ruled out. However there was still a manual option to "Restore Upgrade Errors"
I tried this, and had to enter the phones IMEI and what OS it was currently running (ranging from Froyo to Kitkat, so I selected Kitkat) while LG PC Suite attempted to download the correct software (presumably pulling a .kdz from its servers?).
It was taking a long time, and I was unhopeful of any recovery due to the apparent lack of communication between phone and computer. So I left it and went for lunch.
Upon returning, much to my surprise, LG PC Suite has closed itself down. But my phone was displaying the "Android is upgrading" in Lollipop-esque font. Looking promising I thought...
5 minutes later and all my apps have optimised, my D855 has booted into fully fledged Lollipop! V20f!
So after a brief scare, everything seems to be resolved for now!
I have the same problem but i cant even install the MTP device driver I'll let you know if it worked for me.

I intended rooting my LG G3 S with STOCK Lollipop with LG Root Script v1.2.
Never did it before, so when I started the script I though it was done after first part completed and phone screen became normal. So I closed the LG Root Script v1.2 before it finished it's job. Next thing I notice my phone rebooted and it went into Firmware update.
There was no progress, buttons didn't work, my computer detected the device was unplugged/plugged back in, adb didn't detect the device anymore, so thankfully I found your post and used the LG Suite to start Restore upgrade errors which after it analyzed and downloaded fixed my phone within an hour automatically
Hi guys, here is my problem:
I have the 815P version of lg g4. i upgraded to marshmallow last year via kdz=> lgup=>upgrade and i made the mistake to ENCRYPTthe phone.
today i wanted to go back to lollipop because i prefer root over the newest android. got the right kdz, got the right drivers and did the deed. The thing is, i forgot to unecrypt prior to downgrading
and now im stuck in a bootloop. I can go as far as asking to input the encryption password but then the phone just sits there. I have waited for 15 minutes and it just shows me lg logo, so im guessing its a bootloop alright.
Tried the usual stuff: unplug the battery, plug it again, press up and connect the usb cable...doesnt do anything, lg up doesnt recognize it. What options do i have? im about to cry now :crying:
All I could find is to boot into fastboot use the following command:
fastboot erase userdata
And perform a factory reset again

Thanks for the response. It was a defective usb cable that was preventing me from going download mode. i used the original cable and was able to upgrade to MM, remove encryption and downgrade to LP again.
I have been having issues with my phone random restarting and sometimes it would go through the app optimization process. So I decided to do a full wipe and install CM13. Everything has been great for the past week but, today it did a random restart and went through the optimization process. However, this time it didn't come out of it but, instead looped back to the boot animation and then optimized again and continued to do this. I tried opening recovery to wipe and reinstall but TWRP gets stuck at the splash screen. I have tried reverting to stock but for some reason the LG Flash Tool gets stuck at "Waiting for Connection". I have tried different computers and USB ports to get the Flash Tool to work but have not had any luck. I'm looking for any help or suggestions that people can give. I am willing to try pretty much anything right now.
Resolved! Used LG Sync to Restore Upgrade and revert to stock.
Try the official LG pc suite.
Once connected, just find something like "restore". The program will automatically rewrite the complete storage chip on your phone.
I'm stuck and confused:
Had a Nexus 4 and 5 for years. Decided to upgrade this past November to the LG G4 (T-Mobile H811)
Got it to root without touching the boot loader.
In came MM and then I had issues of repeating the process.
I came across a solution, to unlock my bootloader. So I did it and managed to get my G4 rooted while running stock LG MM (H81120i).
Everything was running well for several months, but then I started to see erratic behavior. It would heat-up in my pocket for no reason. It would not save pictures. Connections via WiFi and LTE were breaking up. All in all, I wasn't happy and I missed the stock Google interface.
So I've decided to install CM13. Had many issues of getting it to work for several days, which included persistent closings of Google Play services (and many others) and not being able to make/receive calls (it would automatically reboot) After several different attempts, I managed to get it all working. Cleared/Wiped everything off my internal drive, installed the "LG-H81120i-Flashable.COMPLETE" and "cm-13.0-201605xx-NIGHTLY-h811" and "open_gapps-arm64-6.0-nano-201605xx", all back to back. And then installed manual everything as needed Gmail, Maps, etc.
Everything worked great for about 2-days, until then next morning my screen locked up. Then the phone rebooted. After the reboot, it lasted for about 10-15 seconds in CM13 and rebooted again manually. Continued to reboot over and over, till it then stopped booting with CM13. I thought that maybe I needed to install the latest CM13 zip file, but found I couldn't get into recovery. The first reboot screen, showing "Bootloader State: Bootloader unlocked? and the LG logo would be in a loop. During that time, I could feel the phone getting hotter and hotter.
Sometimes, the phone would boot up into CM fully and last for 5 to 10 minutes. Then reboot again and stay in the first reboot screen.
I managed to get into TWRP recovery and thought that putting back the stock MRA58K image would help. During the install in recovery, the phone rebooted! I never thought it could do that. Eventually I got the stock LG back-up up and running, but it didn’t help, and same rebooting occurred.
I'm stuck and out of options. I would like to get the phone BACK TO STOCK and then perform an RMA. I’m afraid that with the BOOTLOADER UNLOCKED that my RMA will be denied and I’m stuck with what I have.
So can the H811's bootloader be re-locked?

Since you live in the US your only option is to apply over voltage to the battery terminal and burn the mobo so that it wont even boot up. The exact method is somewhere around here in xda so you should look it up since you have no other choice
Edit: To answer your question: No

If I can't re-lock the bootloader, has anyone had the success of returning their phones under warranty? Through T-Mobile?
Okay, So let me start from the beginning so I'm certain I'm being descriptive enough.
The other night my G3's wifi stopped working. When I went to turn it on in settings it would turn itself back off. Which I thought was strange. So, I assumed it was a software issue so I backed up any important items and factory reset my phone last night. That went over fine. Wifi worked again, all was good. Until, it said it needed an Android Software Update. I hit "update" and allowed it to do its thing. About halfway through the update the phone said "error." With an icon of the Android bot with a hazard triangle sticking out from it. I let it be for a bit and nothing happened. So in my impatience I took the battery out and put it back in and tried to restart the phone. This is where the issue occurs. The phone keeps booting to recovery mode. I'm not savvy at all with Android so I don't know if these mean anything but it says "Android System Recovery <3e> LRX21Y" The phone has had zero modifications done to it. I would really appreciate any help or any tutorials that could save the phone until my g6 preorder comes in.
Thanks!
Kyle
Your phone failed the update for some weird reasons and is now stuck. I'm afraid you'll need to restore stock Android using LG Flash tools and KDZ files to your device. It will get your phone working, but you'll lose your data in the process.
You can try mounting the phone from recovery or download mode and see if you can access your data and backup the data. You can also try the recovery option without downloading wnloaing a KDZ first.
You can fins tutorials around the forum, in the general section usually.
