First of i'd like to thank the community! I've ran in to numerous issues and have been graciously saved several times.
I'll start of by providing some context in to the issue.
original configuration:
Unlocked - T-Mobile US SIM
AT&T LG E980 factory tot 4.1.2 - flashed using LG Flashing Tool
Root - E980 Universal Root
Unlocked Bootloader - Freegee [Android Marketplace]
Installed Recovery TWRP v2.6 - Freegee [Android Marketplace]
Removed bloatware - AT&T Applications
So from this point the phone was working as expected. I spent hours configuring to my liking and decided to call it a night. Before I called it quits I decided to make a backup using TWRP. Backup took a really long time but it said successful. I left handset plugged in to charger overnight, roughly 6 hours of continuous charging. When I woke up I noticed the phone was in recovery mode. Touchscreen was also unresponsive. I held the power button to allow it to reboot and it rebooted me back to recovery. At this point I knew something was wrong. I attempted to re-install backup files made from previous night, this failed. The phone booted back to recovery. I then installing some zip files I had pre-loaded on to the external SD card, this was CM10.1 and gapps files for E980. I tried this out a few days ago and it was working fine. I decided lets try installing this and see what happens. Install was successful and rebooted. The phone boots back in to recovery. At this point I'm really frustrated. I checked the memory card by running through the TWRP menu. I noticed the file sizes were unchanged but the files were not displayed on both in/ext memory. I decided to finally restore again by using LG Flashing Tool. This by the way has saved my a$$ numerous times. So the one thing I would note, at the 85% when the phone reboots I noticed there was an error, an error I've never seen before. It was a picture of sync icon (large) and android man on top of it and text that said "error 0x123456" I didn't note the exact string. I let it go and monitored the flashing tool, somewhere around 93-95% it rebooted again in to the normal boot sequence. Viola my phone is back to where I started.
So here's some of the questions I had:
How did I end up in the TWRP Recovery boot loop?
Why could I not see the files to install once in TWRP?
Why did TWRP continuously boot back in to recovery mode after successful install of restore?
Why did TWRP continuously boot back in to recovery mode after successful install of CM10.1/gapps zip?
Has anyone seen the LG Flashing Tool error I described above and does anyone have an explanation as to what happened?
Here's my theory on what happened...
My phone was on 4.1.2 as mentioned. I noticed a few times that there was a notification stating the phone had a OTA software update available. The first time I tried to update (already rooted and unlocked) the phone failed to update. The error cited that my phone was believed to be rooted. I paid no attention to this and decided to continue using. Later in the day I noticed the notification again, I opted to try again. The phone updated, or at least tried to. It kept booting in to TWRP Recovery. Nothing I could do could restore it, except flashing using the LG Tool. After experiencing this I knew to leave the OTA alone. I don't know if this is possible but somehow I think the OTA was pushed and forced through while I was sleeping allowing the phone to charge. This is the only time I've seen that behavior. Is that even possible???
Where am I now...?
Phone is restored, I opted to upgrade using the OTA before I start tinkering again. Maybe I won't mess with it at all and leave it alone at this point.

Hello there good folks of XDA,
I'm at work right now and my phone is at home but here is the story of what went down last night.
I tried to root my phone, after installing TWRP and superuser I ran a root-check app and it said that I was not rooted, so not thinking I tried the 'fix permissions' function of TWRP and then everything went haywire.
It's an international version M8 that I've had rooted before but reverted back to stock to get the lollipop OTA updateBy haywire I mean the phone booted up but no widgets displayed and most of the apps still appeared in the app drawer but nothing would open.
Instead of seeking help at this point I went to town on trying various things :silly:
The last of which was try and flash a boot image to it, but I think I must've used the wrong one as after doing that it's now stuck in a boot into TWRP loop.
From when I had previously rooted the phone I had a boot image (I think) 2.22.401, it matched version on the recovery file I used when reverting to stock in the past so I thought it would be fine
I've still got a terminal open at home with all the results of the fastboot getvar all command but from memory my CID was HTC_044
Can someone help outline the process and possibly even the files I need to reflash my phone into a working order. (it doesn't need to be 'stock' but that would be best)
I use a mac by default but I do have a windows machine at the ready I can use so feel free to base any tips on doing it from either platform
Post the getvar all output, minus IMEI and serial number, and we'll go from there
Thanks for coming to my assistance but in the end (after a few more slight failures) I managed solve the problems myself.
I believe that my first problem was using a not up-to-date version of TWRP (2.7) with Lollipop; the first symptom was my attempt at rooting my phone, the process appeared to go well but just wasn't working properly.
My second problem was 'fixing permissions'; after doing that my phone went totally haywire and while it would boot into android nothing would work properly
After going to a previously used stock recovery and getting nowhere I went back to the same TWRP I started this with and still had fixed nothing.
at this point I did a factory reset from the recovery mode and while that got me booting back into android I was being swamped with error messages and couldn't get past setup wizard crashing.
At this point I flashed the wrong boot image and had a nearly impossible time getting to the system boot menu instead of TWRP being what it always went to. Eventually I must've got the timing right with the buttons or something because I got back into the system boot menu and could access fastboot.
Once in fastboot I downloaded a full nandroid backup and restored it, my phone was working again... or so I thought, it was still suffering from permissions problems
at this point I re-rooted it with the latest TWRP, got SuperSU working properly, did the 'restorecon' command with a terminal app and now the app crashes I was getting have stopped and I can see and write to the phone memory.
After trying to test everything I could think of on my phone today I think it's finally fixed.
I tried to do a partial/selective app+data restore from a nandroid backup I took of my own phone just after the 'fix permissions' event but it didn't work properly so in the end I manually re-setup my phone. I do run an sms backup app so overall I only lost time...
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.
My Zenfone 2 (ZE551ML 4GB) dilemma:
*•*I unlocked the bootloader with the official bootloader app
*•*I flashed the latest TWRP via adb. In the recovery screen, I saw an android showing error. That's when the panic started.
*•*I Then I rooted my phone with the one click Zenfone root application (available in XDA)
*•*I installed the official TWRP manager from the playstore and flashed with it. That also didn't solve my problem. Actually, a new problem set in. The phone started bootlooping IN RECOVERY.
*•*I rebooted the phone and then flashed an old version of TWRP for my phone. That solved the problem.
*•*Now, I wanted to flash Lineage OS in my phone. According to a YouTube tutorial, I copied my required files (the custom ROM and OpenGAPPS) to my Micro SD and then from twrp's advanced wipe, deleted everything except for Micro SD. I know that was an extremely stupid move but please bear with me.
*•*Deleting everything made things hundred times worse. It seemed impossible to get the phone into recovery mode again. But after a long time, I did.
*•*Now onto flashing the new ROM. I did a factory reset with twrp and then flashed the ROM and immediately got Error 7. By googling a bit, I found that the only way to solve this problem was by deleting the assert lines from the updater-script in meta/com/google/android inside the ROM.
*•* When I reflashed it, the process completed but it showed an error: (E:unknown command [log])
*•* Then I overlooked it again as a quick google said it didn't matter. Then I successfully flashed OpenGAPPS. I rebooted my phone and it kept bootlooping until it was back in the recovery screen. Weird right?
*•*I didn't seem to find any workaround so I decided to restore stock ROM. I downloaded it and flashed it. It succeeded. I rebooted my phone. And. .
*•*My phone now vibrates when I power on the phone and then it shows a black screen. It reboots automatically. I know it does as the phone vibrated periodically after the reboot
*•* I also can't go into the bootloader menu. My phone seems dead but I really need to revive it. I can't afford a new phone. Could you guys help me out please?

Did you flash the MM bootloader compatible TWRP mentioned in the OP for LineageOS? That solves error 7.

I did not do that. I remembered all the steps but forgot that. That is the primary cause of my problem. Anyway to solve it?

xfstk is the only way. go to following thread and do as suggested. one advice when you get into bootloader. flash raw without AFT. that is best.

So, I screwed up. I accidentally wiped my phone in TWRP and lost the backup I had.
After failing to get it to run for several hours (update via dload folder would abort after 5%, flash via fb would just crash on boot) I was able to at least have it run Android (8.0.0.330). However, the phone is now buggy and won't recognize my SIM, nor load my backup from Google, nor load system updates.
I'm not sure what else to try and I don't really want to trial & error my way through all other firmwares. Any ideas how to fix this?
edit: Fixed my problem. Apparently service ROM updates fail if the device isn't sufficiently charged. I charged it to 100%, then installed this ROM as usual:
- put dload folder on SDcard
- hold vol up AND down AND power
- wait for recovery
Hope this helps anyone who makes the same mistake.

Use erecovery. When phone is on the unlocked bootloader screen, press and hold volume up. From the erecovery screen select download latest full package (similar message)
Recently there have several people claim that erecovery is finally working. (Previously there was no response from the server)
Unfortunately I was also getting no response from erecovery.
In good news, charging my phone overnight and dload-flashing the newest full OTA I could find (and checking that region is correct - it might've been russian the last time) fixed the connectivity issue. Didn't consider it the first time since I was >50% charged, but apparently there's some threshold under which system updates will be canceled. TIL.
Now I can't connect to Google's servers to get into Play Store, but I'll figure it out. Will update when fixed in case anyone else makes my silly mistake.
edit: I'm not sure what fixed it, but after flashing gapps got my phone stuck in a boot loop, I restored the system via dload again and now everything's working fine. Weird.
