The LG-G3 update caused a boot loop, how can I get out of it?

[the Core]

Glad to hear it worked for some. I hope you don't get the same issue as I do have right now: the blue screen error.

Re: LG-G3 Update caused a boot loop

Did you hold the down volume button right after you turned it on because that will put it in safe mode and you can go and connect to the LG pc suite and then you can fix update error

Re: LG-G3 Update caused a boot loop

Okay ya'll, I'm a total newbie on these forums, but my G3 started this dreaded reboot loop just last night. I've tried the paper trick, has not worked. I've tried hard factory reset, still hasn't worked. NOTHING has worked and now my G3 seems inoperable. The screen has now also stated "Security Error" with the LG logo screen, then goes black with the LED light alternating red/blue. If anything anyone knows here to do, please reply here or directly to my account, that would be greatly appreciated. Thanks so much! By the way, I took it into a cell repair place today and they also could do nothing due to it being a software issue. Again, any help would be appreciated, thanks!

I've had 2 G3's and the OEM battery caused issues in both. The first had constant boot loops, and the 2nd random restarting with stock battery. I replaced the battery with an Anker battery and have not had an issue with either phone. Also tried another battery from ebay, and it would shut down randomly and not restart without removing the battery. Seems these phones are very sensitive to the power source.

Buying a new official battery. The lifespan is terrible. I already need to buy again.

After a month of random reboots I have found this post here and it FIXED my problem ...
I just put a piece of paper in order to add pressure to either one of the two contacts (poles) of the battery with the power control chip.
My phone rebooted just one more time for the last 24 hours, but the battery was below 9% and I switched on GPS, I know that the battery i probably damaged of all this rebots during the last month, I'm going to purchase a new genuine battery BUT I'll use it only with the piece of paper below the SD card - as it's shown here
Thank you very to "The Core"!

SOLVED!!

Your solution involving a tiny piece of paper worked for me!
My phone started acting crazy few months and, getting worse over the time. After a reset, the problem of switching itself off was gone only for few days, so I was about buying a new phone, not from LG, the next day. After reading your post, I tried your simple solution, and it worked. 4 days have past, no switching off!
Thank you all, guys!
Cheers,
Daniel.

My problem first started with the phone randomly not recognising the sim card, then the random rebooting. Battery performance was erratic so I bought a new one. It got to the point after about 6 weeks where it was stuck in a boot loop and it wouldn't even go into download mode. Tried the Factory reset and that didn't help. Ended up getting a Galaxy S7 but still trying everything to fix the G3. Stuck a piece of cardboard between the battery and sim card and booted first time, working great. Thanks for the advice. Only wish I had stumbled across the solution earlier.

Re: LG-G3 Update caused a boot loop

I think I kicked my wife's in the ****....
I shoved it on a 1amp charger and pressed and held the power button until it restarted then while it was restarting I pressed the power button 5 times and now it turned on out of the boot loop. Shes either going to hate me or love me in the morning when she can recover her photos....cause I stayed up messing with it.. either way a try can't be any worse than the factory reset option.

The newest system update for the LG-G3 was released recently and I decided to install it today. After it downloaded, the phone said that it would restart. Once it started to power back on, it went to the "LG Life's Good" start up screen, stays at this screen for about 10 seconds, goes dark for 3 seconds, then repeats this process indefinitely. I've seen that this is called a boot loop and I've attempted to perform a factory reset on the phone based on some youtube tutorials, but all of them require that you enter "Download Mode" (which the phone does successfully), and then the screen should show a "Firmware Update" screen, which my phone does not go to. When I open Device Manager, the phone is listed under "Other devices" and the name "QHSUSB_BULK".

Thanks for you help.

Re: LG-G3 Update caused a boot loop

How can I get past this shutting down crap without a computer?

Ok my phone got stuck with zero charge on firmware mode, did not let me do anything till I hold the power b and the the volume buttons at the same time for about 30 seconds then the LG logo appear on screen, then a reboot mobile appeared in a blue screen then I pressed the power bottom and recover service, got it?

Re: LG-G3 Update caused a boot loop

Many thanks for your instructions. They were the only ones that worked for my LG G3. Thank you for taking the time to write all the instructions.

My dad has had this issue lately. Would be using the phone and it would randomly turn off, boot loop a bunch of times and finally start up again. I reset the phone for him and still happens. Researched it and it seems it has to be the battery. Phone operates fine without reboots/boot loops when plugged into a charger. Unplug it from charger and the phone shuts down and goes into boot loop. Ordered a battery and will get tomorrow. Hopefully that fixes it as I've read it has for others.

It is possible to do it the Samsung way but not with odin it's called lg flash tool it's like odin once the phone is in firmware update mode insert the stock rom into flash tool and your ready to go I can't give a much more detailed guide than that as I'm having issues with my lg after update it's barley usable but if anyone has any luck please do let me no as it's doing my head in trying to get my phone back

I had a bootloop and was trying to figure it out for last few hours. Tried factory reset, flashing software with LG Mobile Support Tool (booted once after that but as soon as I started setup it went to bootloop again) I even tried the paper pice on battery thing. Nothing helped untill I swapped battery from another G3 I have. Works fine since last 30min or so. Already did initial setup. Hope it will help someone.

Re: LG-G3 Update caused a boot loop

Hay Gys. hope you are all well. i am facing a rather different issue with my lg g3 phone. i could not found any solution on net. Actually it restarts while detecting network signals and then it keep restarting so when startup screen comes and phone searches for signals it restarts and o the loop continuous. My phone enter such loop when 3g signals get drooped from my network provider. But it should restart with 2g signals right? but it doesn't and it enters the restart loop on signal detection. Please help i would be thankful.
After all when i eject the sim card it starts normal. the issue is with the signal detection. i hope you could suggest a solution. Thanks

HI, I have the same problem, any fix??

Re: LG-G3 Update caused a boot loop

I have the same issue and am super frustrated. I attempted to do a reset, but when i do, it sends me back into the same bootloop. Additionally, the phone turns on and is sent into the bootloop by simply plugging in a charger. At this point I can't figure out a way to charge it back up fully which is complicating things more. Let me know if you find a fix!

me too...the exact same problem!
