Alright so normally I don't mess things up this bad... But I did something stupid by replacing LG system ui with the one from the port hybrid theme for our US carrier phones. Needless to say its not made for 13B update that just came out. Tried it anyway to see if it would work...nope. Phone won't boot up all the way. Just gets stuck say "LG system ui stopped responding". I stupidly erased my rooted system img off my phone as well. I tried to factory reset and clear cache. Nada. Anyway I can push the img to my phone via abd? Verizon assistant doesn't have the lastest 13B to reset to. I'm out of ideas. Any suggestions would be greatly appreciated.

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 was on 13B rooted, then flashed the stock system to return to unroot status. Everything worked fine. Plugged into computer and Verizon Upgrade Assistant suggested upgrade to 13C, so I bit. After a 4 hour (!) download of a 2 Gb file, the upgrade install proceeded without incident, and resulted in a successful completion according to the Assistant. Phone started booting and the Upgrade Assistant re-read the phone as being on 13C, but, the phone stalls and refuses to boot past the Verizon red splash screen. I have pulled battery and tried numerous times to boot, with no luck. It just sticks at the same spot.
Any suggestions? I'm nervous about re-flashing 13 B for fear of bricking it, so perhaps flash 13C kdz?
Thanks in advance for any help.
I have now tried flashing the 13C kdz unsuccessfully a number of times. I verified the checksum on the downloaded kdz file, and attempted to flash it on three separate computers where I had successfully flashed the G4 in the past. Each time that I tried flashing the 13C it reads: "Required Information cannot be found. Contact the system administrator."
I am still stuck here. Even in the flash tool, the phone is read as having 13C on it, but it still will not boot past the Verizon splash screen. Any thoughts on whether I should dare try flashing 13B, or would I end up with even more of a brick then I have now?
Thanks again.
DO NOT FLASH 13B!
Isn't Android 6 24c?
I got stuck on the Verizon screen, but a wipe fixed it at that point.

Thanks, and you are correct on the number, MM is 24C.
May I ask, how were you able to wipe when stuck on the Verizon splash screen? I would love to do that if possible.
Thanks again.

Hold volume down and power on if I remember correctly to put the phone in recovery mode. From there you can choose to do a wipe/factory reset.
I had issues with way long boot times, the wipe fixed that, but then apps kept FC. I ended up downloading the KDZ file and used the flash tool to reflash 24C. Everything is stellar now.
Thank you so much, mikeewhite! I followed your instructions and they worked perfectly, so I am back up and running. You are the reason that I love this list so much, as there are so many people like you generous with their time and advice.
Hello, I recently went to upgrade Cyanogenmod 12 to Marshmallow, everything went fine, but when I went to reboot the system I got stuck in a boot loop. Following this I wiped my system, data, and stupidly my internal storage so I lost my nandroid backup. Installed earlier firmware (Android 4.4.4), everything worked but my system didnt recognize the SIM card. Opened LG Flash tool and went back to bone stock LG, rebooted and get stuck in intermittent boot loops in varying places along the setup process and once I get to the homescreen with many versions of the Verizon LG software varying from 5.0 to 6.0. I suspect my system permissions are all f***ed but I dont know for sure as I can't get the phone far enough to enable USB debugging. Enabling it in the stock system recovery screen doesnt seem to work. I've gone through many of the threads here regarding boot loops for the G3, but havent seen any with the stock hardware.......Any thoughts on where to go from here?
Bump. Please, any help would be appreciated
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!

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.
I was running the latest version of TWRP and a rooted version of the LG G6 port. Everything was stable and worked fine. So I was ready to give it back to its owner who I had modded it for. I went into the settings menu of the phone and did a standard factory reset to remove my account that was logged in so I could test the phone out before giving it to the owner. well when it finished resetting and rebooted, its been stuck in a boot loop ever since.
Tried just clearing both Dalvik Cache and Cache, to no avail. Tried Reflashing the rom and starting over. Still nothing. Tried flashing a different rom. Still nothing.
So what else can I try? and also if its the only thing I can do, rest it all the way back to stock factory everything. How do I do that on this phone. What program do I need and what files. and whats the steps to complete the process.
Thank you in advance for all help that is given
i factory reset in twrp and turned on developers options after first boot then reflashed twrp i always forget backup lol or delete it or use kdz you flashed before anyway i can help i will if you still need
if you have tried to flash the same custom rom or another is still not working, flashes with the program "lg up", you will need a kdz file,and the corresponding drivers. if with that you can not watch this tutorial before doing anything.
if you have a backup made with twrp, it flashes again.

during this process you will have to disassemble the back of the phone, (plastic) you do not need to remove the motherboard completely from the phone, anyway if you can enter download mode try with lg up tool.
if you need help around here we are.
Well now in the process of trying to fix it. The phone bricked and will no longer turn on at all. Is there anyway to fix this ?

Can you get into download mode?
Also, it's possible you have been hit by the bootloop
