Hello, I need help with my G3 verizon model. The problem is that my phone restarts itself but just when I try to flash any rom, zip, etc. I was using it when it first shut down, that was today, I tried to turn it on, and it went to the logo and restarted, so I went into recovery mode (TWRP) and triend to make a clean Fulmics install (my current rom when the issue happened was AICP lastest version), but the problem is that if I try to flash ANYTHING, the phone just shuts down.
I don't know what to do, I tried to flash it via download mode with lg flash tool and the same, I go into download mode, I plug the phone and start de process but it shuts down before starting any flash.

Sounds like a bad battery. Have you tried a new one yet?
*If you live in Murica you can get a genuine replacement from LG for $15:good:... http://www.lg.com/us/cell-phone-batteries
*Anker also makes a decent replacement as well.
Good luck :fingers-crossed:

You think so? I don't know, because I tried to leave the phone on, and it doesn't tuns off if it's just in the lg logo because as I said it hasn't any system or rom right now. The problem is just when trying to flash anything. But anyways thanks, and I'm going to try with a new battery as soon as posible.

First, what rom did you flash and how did you flash it?
Try this as well:
Pull the battery, press the power button for a few seconds. Put the battery back in and press the power button again. Pop the battery out a 2nd time and then put it back in. See if it turns on.
If that doesn't work, pull the battery and hook the phone up (without the battery) to a computer and again see if it turns on and shows up in device manager.
Flashing the wrong rom should only result in a non-booting situation. If you have a custom recovery installed, you should be able to still get into that. The d850 has some serious issues with successfully rebooting in general (which can be resolved by the two suggested procedures above), so I would suspect that before worrying about a brick.
Lastly, the d850 requires bumped ROMs to get by the locked bootloader. The d851 (T-Mobile version) does not have a locked bootloader, so the roms are not bumped and will of course fail to boot.
Once you get back into recovery, just wipe all partitions except for internal storage/sd card and install a correct rom.

When you say you got the phone on, what do you mean?
If it is on and showing up as a phone in Windows, why not just use the LG recovery tool and flash back to stock, then start over?

Give the lg firmware flash and recovery tools a go then. There are several threads on here dealing with unbricking phones that detail what you need to do.

Did you solved it? I have the same problem, the screen only turns on when i charge the phone
Earlier today I was using my phone I forget what exactly I was doing I think I was using the web browser or opening an app. The phone randomly restarted and after the LG Logo screen appeared I got a blue screen for about 10 to 15 seconds and the screen went off. I pulled the battery to see if that would help but that didn't work. Tried safe mode and even factory reset both times got the blue screen (can get the little menu tho) I then plugged the phone into the computer and initially I could get it into download mode. But after installing the LG drivers, and installing LG Flash Tool I went to flash it back to stock. (My phone has pretty much been stock and unrooted except for the lollipop update. ) When I went to flash the phone screen went blue and the flash tool was unsuccesful at implementing the flash. I also tried the LG Mobile Support Tool. Now intermittently I can get the phone into download mode and get the computer to recognize the phone and LG Flash Tool to the ready stage to flash but after that no luck. Any suggestions? I have not tried fastboot or kdz conversions as I dont think those apply to my problem but I could be wrong

I work on phones for a living. Unfortunately, i think the motherboard is bad. Nothing you can do.
Bake at 350 for 10 minutes

I know this sounds ridiculous but I just did it this weekend and IT WORKS. I pre-heated my oven to 350, removed the motherboard (without sim and/or SD card) and placed it in the middle of my oven on a piece of white paper for EXACTLY 10 minutes. Afterwards, I let it cool and re-assembled. My phone is now working perfectly and I didn't lose any data that was on my phone. I was able to back up my data and am still using it, although I am prepared for it to fail again at any point. I know this sounds absurd but it works. I would post the link but I can't until I've placed 10 posts. I thought this was important enough to share with others and that is why I created an account here. If the moderators look at this please add the link. you can just search Google for "lg g3 blue screen fix oven" and it is the first result right now on forums.androidcentral.com. I'm gonna go ahead and use my phone until it dies again, but for the last 48 hours it has been working flawlessly.
Hey guys my verizon g4 is stuck in bootloop and im not rooted, i cant get the past the lg boot screen, it stays on their for around 20 seconds goes black and back to lg screen.
I can get into recovery but none of the options do anything ive tried safe mode, usb debug mode i even tried factory reset they all just go back to the lg screen.
I was just watching a video on facebook when it froze restarted and now im stuck, ive been restarting it all day and i was able to get it to boot up twice but it froze again within seconds any help is appreciated
it might be the defective motherboard issue that people are having. you could try reflashing the system, but if that doesn't work you probably need a new motherboard/phone
Not an answer, but an experience.
I have an HTC ONE M8, VZW. I s-offed it and rooted it right when I got it. I began adding some of my google apps and it did what your G4 is doing, stuck on VZW screen.
Since I was s-off I was able to get a recovery in and ready. I was able to get a custom rom onto the phones external sd. I flashed it with the recovery and the flash took, no more vzw screen lock up.
Your experience makes me wonder what VZW is doing to force bootloops on unlocked or rooted phones with their retail products. Paranoid maybe, but I can see VZW deliberately adding code to stick it to rooted users.....................................I say this still knowing that many have rooted the current run of devices without issues...........................
luck
i read about the problems with the motherboard going bad, im assuming thats what happened to mine. Lg sent me a replacement under warranty
Update!
i called verizon they sending me a replacement. just to let you know i flashed 13B KDZ but the bootloop was still there i let my phone on and finally turned on quickly i did a factory reset and booted up normal and its working again. still im gonna send it back. just sharing my experience maybe for other people might work too.

What is the 13B KDZ and how did you flash it? Im having same exact issue.
My G4 tanked over the weekend. I was browsing news and the phone locked up, then it shut off and turned back on. It just bootloops now. If I stick it in the freeze for a few minutes, sometimes it will boot to the OS where it starts to optimize the apps. It will get through about 20 before it shuts off and starts the bootloop process again. I haven't even been able to get the download mode to stay on, and when it does enter download mode, it is not detected by the computer. I think my problem is the motherboard. I'm just hoping that they aren't able to figure out I had it rooted!
I'm still waiting to hear back from Verizon about a replacement.
Does anyone have any ideas on how I can flash a stock rom back on this thing to try to save my tail? I am betting not since the phone won't stay on long enough to even flash the rom.

My phone was rooted and got into the bootloop also and I sent it in as is and nothing happened. So I think it would be fine to send it without the stock rom.

They mailed me a new one, no battery, no back. I put my battery, sim card, sd card, and back on the new phone, fired it up. Rolled it back, rooted it, then I mailed the old one back.
Personally, I love this phone, but I think I will be getting a nexus next.
Good evening everyone,
I come to you guys with a very particular problem. The LG G4 in question is an H815T (Asian variant). Let me clarify right now, it was not bootlooping. This one was getting STUCK at the LG logo, it didn't restart to it multiple times, it just got stuck there one day after turning off by itself. It did go into the download mode, though.
It went into the first part of the recovery, but when you selected that you wanted to factory reset, it got stuck there. The only way to get it out of the logo or the stuck recovery was taking the battery out. Interestingly enough, the phone DID charge at the stuck logo, albeit not so much due to the screen being constantly on at full brightness.
An even more interesting fact... I managed to fix it! I flashed the KDZ corresponding to the latest LP for the H815T, after the process was done, it did bootloop. I found the YouTube video about flashing a certain file to deactivate most of the cores and said "what the hell have I got to lose?"
Flashed the KDZ and.... VOILA! It showed the Recovery Android doing its job at Format Resetting !
Something even crazier... The phone booted into AndroidLP, I was worried about the cores thing, but the phone seemed to work at full speed... I was surprised to run HWmonitor and notice that all of the cores were active. The phone was fully working!!! Or so I thought... Now I have TWO problems:
I cannot update to MM. If I try to update from the phone itself (because it does say there's a new version available) I go back to being stuck at the LG logo.
When I make a call the screen goes off... nothing I do will turn it on, and if the other person does not hang up, the phone will remain locked. However, if I plug in a headset everything works normally.
Is there anything I can do about these two problems? Please, leave your comments and questions, I think this phone is pretty weird and I found nothing else like it on YouTube or here on XDA.
Take care :good:!
Idk for the call but for the mm you could try using something like lg mobile update tool... Something like that.
Be warned cuz i dont know if it will bootloop.

Got it! The sensors thing was definitely it for the screen problem. I also read this is very common with many screen protectors in 5.1.
Do you have any ideas regarding the issue updating to MM?

All good, Willy! Even is you're stuck at the LG logo, take your battery out, or it back in BUT DON'T TURN IT ON... Instead, try to access DOWNLOAD MODE. If you're able to do it, you can flash any KDZ you want, but be careful.

Yes ur right using a heavy screen protector will block all the sensors so ya try removing it... No issues in MM u can try OTA through wifi

your screen protector had the sensors covered . you need one with the cut out in the speaker and sensors..
So my mom had an LG G3 D850 from at&t. was totally fine, then she updated whatever she had to 6.0 and it started bootlooping. Tried the LG Flash tool with a tot stock firmware. Went through the whole process got the blue screen with the red 3, it restarted, kept bootlooping. Tried it again but then it got stuck on 5% for like 4 hours, unplugged it and now no matter what i do i cant get into download mode. It shows the LG screen then goes straight to firmware update (even if i dont hold vol up) and it says 910K Bxx QEM (the xx changes) I was able to get into recovery mode, recovered it. same thing. Im losing my mind a little bit here so any advice, or pointing me to a tutorial would be greatly appreciated. Ive looked all over the internet and cant find anything helpful apparently the qualcomm thing where you short the motherboard doesnt work for this phone either?

If it is under warranty .send your phone to at&t to get it fixed.

Qualcmomm method you are describing is just to bring your phone into download mode. I have done this to my brother's g3. You have to flash using LG flashtool using different settings and then hard reset your phone. If it doesn't solve your problem.try to replace battery and then use custom rom.
tried that

Try LG PC Suite go to option update error recovery it will download the stock rom flash it dont worry it will take some time so be patient also what happened is when ur g3 wasnt fully updated meaning it got stuck or turned off when updating
.hit like if its helps
