I've looked all over for a definitive answer on this, and can't seem to find anyone with the exact problem I'm having. When I first got this phone it came with 4.4.2 jellybean. Eventually I was notified of a software update so I went ahead and installed it. To my horror, not only did it update to Android 5.0.1 (yuck!), it also installed McAfee. After this, my battery life became so bad I had no choice but to root the phone and flash a custom rom. However, when doing this I didn't realize that McAfee had a lock feature, so after getting TWRP, rooting, and installing my custom ROM (OctOS Android 5.1.1), I rebooted to a screen saying that the device was locked. After rebooting several times and wiping and reinstalling some things (I don't know exactly how this next part happened), I finally got the phone to boot and the 'locked by McAfee' screen no longer shows up... but now, the phone boot loops about half the time, and when it does boot it always goes through the "optimizing android" step, as if the phone has just been booted for the first time with a fresh rom. What can I do to fix this? I can only assume that McAfee is somehow involved here, but I'm not even sure at this point. Any help or advice would be greatly appreciated. Thanks!

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.
For some reason my phone isn't booting up all the way to the rom/OS. It gets stuck on the boot animation and goes on forever and hasn't been able to boot up since yesterday, when my powered off at 20% battery, which is something normal for my phone. I was rooted and on android 4.3/MK4, but when I put it to charge and tried booting it back up, the phone would boot up, but would get stuck on the boot animation, going on forever. It wouldn't freeze it would just continue to play the animation. I tried removing the battery, factory wiping it, and installing a new rom, which I found out was for a different baseband. When i finished installing it it still wouldn't boot up all the way through.:crying: I then tried installing the previous rom, and still no good. After all that I installed a stock firmware using odin, hoping it would work. I installed the 4.4.2 NE2 firmware, which isn't for my phone but watching zedomax's video, he said to download the latest build date, which is what I did. Well, downloaded it and flashed it through Odin with a PASS and everything going good. Although, when it was rebooting-even after a factory and cache wipe-it still wouldn't boot up. I tried installing other firmwares aswell, but still no luck. I'm just waiting for it to finally boot up, so if anyone can help me out, I WOULD GREATLY APPRECIATE IT, otherwise, anything is going to help at this point. Since I flashed the firmware, I now have a stock recovery and rom(I hope). I've been through these types of situations, but not to this point.. :crying:
It seems odds, but you may want to try a new battery. I recently went through a total disaster with my device and it ultimately was the battery. You may want to try booting with it connected to the a/c wall charger. It may give you an indication.
Have you tried the quick fix posted? My phone did the same thing when i had the stock recovery it showed error mounting efs folder. I noticed after installing clockwork that error didnt show up. It was still the same problem though. Wouldnt hurt to check it out. I got my note two from a friend who described the issue starting the same way you said happend to yours. The phone had never been rooted though. Good luck to you in trying to fix it.

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?
Hello,
today I accidentally tapped on "Update" (to 7.1.1) on my rooted Nexus 5X... Something you usually shouldn't do, but it was 2am and I was tired and.... Doesn't matter. After this my phone rebooted and almost instantly showed the dead android with the message "No command". And now I'm stuck there. After rebooting I still land there.
Since the error message almost instantly appeared and since I still can boot into TWRP (3.0.2-2), I think the update wasn't installed and I hope to find a way to avoid the factory reset of my phone. Do you have some tips or possible solutions what I should do in this case?
Thank you for your help.
Its odd this happened, when rooted and twrp installed. in my experience, the update will just simply fail and it will boot back up.... in your case, it sounds like something flashed but the phone didnt like it.... All I can think of is if you cant get into twrp, boot into fastboot and flash the factory image from google, you will loose all data though.....
EDIT, RE-READ you post, if you CAN get into TWRP, try flashing a backup... you should have a backup I hope, lol... First rule of root and flashing is make a backup asap....LOL
When I rooted my phone I did a backup. But the problem is, it was several months ago. So I tried the only method I could save all my data. It wasn't safe, I knew this, but no risk no fun.
My solution was: Download the ota update from Google and flash it with TWRP... Voila! My phone boots properly with the new update... But this method is like I mentioned before not safe and can probably cause a boot-loop with an overwritten recovery. I had to flash my recovery again, but everything works fine now.
Okay, so I'm not new to flashing roms or anything on this tablet. Been doing it on this particular tablet for years now.
But I think I really screwed up this time. I had been running an older version of Resurrection Remix ( I think it might have been lollipop, around '16 is when I installed it) and the battery was draining really bad suddenly. So after I installed a new battery I thought I'd put on a fresh new OS. Installed Lineage 14.1 and it worked wonderfully.
Then I tried to install TWRP because, I dunno... I didn't like the Cyanogen recovery that was on it.
I installed Rashr, went to install TWRP. Things looked okay, then it reboot. Got stuck at the downloading screen. Said at the top "Could not boot in normal mode."
Installed Kies, wouldn't connect to the tablet.
Installed Odin. Made a connection with the tablet. Still couldn't get rid of the "normal mode" error. Kept messing around with different button combos, popped the tablet open and disconnected the battery. Waited for a minute, put it back in and nothing different.
Finally I managed to get it to not show the "normal mode" error, but it might as well because Odin still doesn't work.
I remember a few years back I had to do some stuff on it to get the newer android OSes working on it, I think it involved repartitioning memory and stuff. So I don't know if I can try to go full KitKat stock rom or if it'll really mess things up.
I just want my tablet working with a recent rom.
I've literally spent 5 hours with this damn thing trying to get it working again and I'm at a total loss, here. Any help from you wonderful XDA folks would be so greatly appreciated!
EDIT:
Okay, so I let the battery drain overnight (the screen wouldn't turn off so it drained pretty quick) and while it's still stuck in Odin mode now it says at the bottom in red Unknown dev_type.
Have no clue what that means but yeah...
