In case anyone else suffers the same symptoms - a couple of weeks ago, my G3 started running really slowly (and possibly a bit hotter).
Booting from cold seemed to take a long time and the ui starred freezing temporarily on a regular basis.
I was waiting for an ota marshmallow update and hoped that would fix whatever was making it go slow.
I was wrong.
The other night, I was using it and the screen went bright blue and the phone then started boot looping. Sometimes it only got as far as the LG logo and other times it for all the way to the lock screen (on a couple of occasions I could get to the desktop and use the phone 'normally'). Every time it ended up blue screening and then rebooting.
Ultimately, it was dead and despite managing a full wipe, nothing fixed it.
As a phone, when it worked it was ok but cracking screen, poor call quality (only realised that when I got a different phone) and general slow downs (possibly related to overheating (and I could only infrequently increase screen brightness to full because of the warning about overheating) means that I think this phone has been fair rather than excellent.
Its motherboard problem only way to fix it is replace it with new one

That's what I thought. Phone is well over a year old, so just got a different one.
Good feedback for anyone who has similar symptoms.
I have the same problem, went to the LG service center in my country
and yes they said that I had to replace the motherboard, because the IC power is broken
the cost is around $160, 1/3 the phone price when I bought it mid 2014
I have only used my phone for only 1.5 years and very disappointed with the quality of G3 phone
same **** happened to me, they replaced the motherboard, luckily it was still under warranty.
Don't update its motherboard problem
Same here blue screen came and phone is dead. Gone to lg service center and they told to replace the motherboard yesterday.
The whole phone now only cost 1000AED and they are telling me that motherboard replacement is gonna cost me 950AED .what the heck, better to buy a new phone. Atleast i will get one yeAr warranty new phone for same cost hehe...
The updation of lg g3 software is the main reason for this, so dont update the phone to new version of android pls.
Sorry to unbury such an older thread.
I just got a new (sic) LG G3 D855. A few minutes after the official LG updates were installed, the screen began flickering, with intermediate blue screens, and consecutive reboots. After a BSOD the screen went dark, and the phone seemd to be powered off. I am not sure about this, but I could not power it on again for approx. 20 minutes. Then it was starting again, but I feel very uncomfortable about it and plan to ask for a replacement, since I have full warranty.
Before I return it:
How to I find out the manufacturing year of the motherboard and/or if there is a newer revision or something? Is it printed on the motherboard or readable via an app (e.g. CPU-Z or similar - if I can start it at all)?
Any help in this regard is very much appreciated. Thank you.
Wishing you all a great year 2020!
Dear community.
A few weeks ago I rooted my LG G3 and installed Fulmics 6.0.
Everything went as planned and worked seemlessly.
Today, while watching YT-videos my device turned off and tried to reeboot. After the first, non-animated LG screen, the blue screen appeared.
Same to say while trying to boot into TWRP recovery. After the blue TeamWin Startscreen, the blue screen shows up again. :crying:
Is there any help left?
Kind regards

My friend also happen problem
He asked people to help take
Finally, open the motherboard
Then take heat
That seems to be a common problem LG G3
Welding where welding is not good
PS. I use google translate
hi guys, i had the same problem now for 2 days searching the forums for any sign of hope even ringing lg them selves to for them to tell me the repairs will cost more than the phone
so i new at this point i had nothing to lose.. after playing around for 13 hours with my phone i have got it all up and running at the minute for a full day an not once gone off so i might be the lucky one buts its worth a shot
this is what i did.
disassembled my lg g3 and took out the logic board
took off both heat i/o sheilds from the i/o
with a fine tooth brush and some contact cleaner (ipa 90%) i cleaned the main part of the board and let it dry out half hour
i then applied hot air onto the board both sides and let the contacts reseat them selves and the put phone back together (make sure you out the i/o shields back on)
i then tried resetting my phone with lg flash tools and the correct fireware for my phone
(when you are cleaning your phone there is a little sticker on the chip stating what firmware you phone came with, find this firm where as you know it will work)
anyways it didnt work for some random reason so i tried lg flash tools 2014 (i will link everything below).
so when i found the correctish .kdz file i flash the firmware making sure everything went
and for the first time it went to 100% first time.
played with my phone for a while all seamed ok wasnt the standard firmware what was on when cam out the factory.
so i then tried lg flash tools again with the correct firmware and it worked spot-on and has never played up are missed a beat since....

Just an quick update the phone is still working like a dream. Also upgraded to lasted OS. So this could of been a lucky fix or just a bad section in software.

I actually just got this yesterday, and fixed it. It started blue-screening and rebooting sporadically but quickly got to the point where I'd turn the phone on and it would blue-screen and shut off after two seconds. I could still hold Vol Down and power to get into the STOCK system recovery screen, and by choosing Safe mode (Factory data reset went to blue-screen) it went into TWRP. I tried a whole bunch of different things (and luckily was able to get a backup of the internal storage to my SD card) before doing a full wipe. FULL wipe. I then flashed the stock image via KDZ which is where I sit right now. No blue-screens. I had been on Jasmine 9.1 and Skydragon kernel, I'm thinking maybe a recent update didn't play nicely with either of those, or maybe some other custom firmwares too.
I also got this and somehow i manage to resurrect the phone. I was installing another stock-based ROM (Zoe ROM 3.0 - based on V30N) and after setup my phone got a blue screen. I unplugged the battery, i tried to start it again but only showed LG logo for one second, and after that was dead. I mean, completely dead. No power, no charging, no PC detection, nada!
What I've done:
1. disassembled the phone and pull out the motherboard (G3 is really easy to disassemble, really);
2. open the protective cover near the CPU/Memory (it's a weak metal cover, easy to pull down);
3. i wiped gently with a toothbrush and alcohol all the components (i put a lot of medicinal alcohol);
4. i used a hair drawer (hot) to clean the excess of alcohol and to heat the CPU zone (about 1-2 min);
5. i assembled all back together and i prayed to God (no joke, believe it or not);
6. after that i pressed the power button + vol- (to enter recovery) ... and surprise, it's alive;
7. i restored a anterior software backup, just in case... (now i use Zoe ROM 2.7 based on V30J);
Now it's working for about ~4 hrs and no problem at all... i will edit this if something is happening.
Good look! And pray... sometime it really helps.

I'd suggest flashing an original factory image and re-rooting / re-installing TWRP.
Worked for me also !!! Without praying

This worked for me! Didn't even need to reset the OS. My wife's G3 shut down on her one day. I started trying to fix it, but couldn't get past it showing blue screen, boot looping, and then going dead to the point where it wouldn't even boot to the flash recovery screen. I couldn't even get it to turn on at all until I took the battery out and held the power button down for 20 sec.
Then I read this post, removed the circuit board and shields on both sides, blow dried on hot/low setting for about 7 min each side, and let it cool off for about 10 min, then re-assembled everything. First boot it went right to the PIN lock screen like normal. So far so good it's been running for about 30 min no issues. Thank you!
Glad it's working mate I got my phone to my little one now and still going strong it did have a little TIFF a few weeks ago with not even turning on but left on charge for a day as for some reason the battery drained that much it couldn't even charge so yeah
Yeah just did a drop test and smacked it around a little, so far so good still going...
I have a solution to this problem.
When you disassembly phone and remove protective cover (from processor site) remove little battery from motherboard - near to processor.
Thats all. G3 is back to live (at least mine)
The bsod happened to me as well. After trying everything, flash stock firmware, boot to recovery and wipe data, cache etc and nothing worked. I then disassembled the phone and put the motherboard in the oven at 180degree for 10 minutes. So far so good, it booted up fine and it's working pretty well till now. Flahed v30b version and it's working since 10 hours. Will report back how long it stay alive eheh

Looks like this disassambling things really works cuz i read so many places and heard from friends that it works.
But really strange why it suddenly started this problem on everybody
I solved the problem by putting CPU limit. It is not a good solution while your phone works as half of its potantial but it works. Maybe one day i will bake it too
Here's another proof that the heatgun solution seems to work.
My G3 was randomly crashing from time to time over last month but the bluescreen appeared for the first time today. Since then it didn't make it past the LG logo before it would turn blue and shut itself of. So same problem as described above.
I took it apart and took of the metal "heatspreaders" from the motherboard, then heatgunned it from both sides for like two minutes each (with waving the heatgun around so I wouldn't burn the entire thing ), let it cool down a little and reassembled it.
I then just powered it up normally and it works just fine.
I'll update you in a few days.

Yeah, it works, in most cases. The question is - for how long... You may be lucky, and it could be a permanent fix for you. However, the nature of the issue is a manufacturing defect which can only be fixed for sure by reballing the chip (or by just replacing the whole board). Going a bit deeper into technical details, the chip in question is a BGA type (Ball Grid Array). It means that it doesn't have traditional leads for soldering on the board (the ones that are either sticking out or just located on the sides). Instead, it has soldering pads on the underside, and the soldering is done by putting a pre-arranged set of solder balls (hence the name), and the flux on the pads, and then heating up the assembly until it melts. A flaw in preparation or in the soldering process itself results in a bad contact on some pads which usually manifests itself either after the chip and board heat up under load, or when the board is physically deformed even a tiny bit (hit or dropped), or just after some deterioration/oxidation over time...
Sorry for the nerdy stuff, I am done now... Basically, consider the heatgun trick to be about the same as banging on the side of the old tube TV trying to fix the static on the screen...
Hey everyone, my last LG G3 just crapped out on me, I had the screen flickering issue that just got worse and rendered the phone unusable. Now I ordered a Refurb from Ebay but I am getting may 3 minutes at first of use then it restarts, then I eventually only get 1 minute before it restarts, this happened out of the box. I already contacted the seller, but while I'm waiting I'd like to try to see if its a software issue and downgrade the phone using the LG Flash tool with the dll and tot files. I've done it many times before with no issues but now it fails every time. Is this caused by the phone running Marshmallow? Is there any work around or can a root and get TWRP on the D850 so I can try to flash a custom ROM? Thanks!
I've been dealing with this for over a year. I first used my warranty and got a new one (or refurbished one idk) and then that one is giving the same exact problem now. If you look online there's loads of people with the same problem and a few proposed solutions none of which seem to work for everybody.
I first tried the connector on the camera trick. It worked for about one day.
Then I tried installing a thermal pad beneath the processor+thermal pad. It worked for a few days.
Then I saw people were baking the motherboard at 350 degrees for 10m and then letting it cool in the oven for 30m that worked for about 2 weeks. I also added the thermal pad cause I'm sure the overheating is what's causing this.
Since that was the longest solution, I've stuck the motherboard in the oven twice now cause the problem keeps coming back.
Today it came back again actually and I placed the phone between my palms right where the processor is and pressed with some force and the problem went away.
I've heard of one more solution which seems the most logical and I haven't seen anyone say it doesn't work: melting soldering paste around the processor using a heat gun as this makes the connections work again.
Sadly I don't have a heat gun and the local phone repair guy wants to charge me $30 so can use his so for now I'm gonna keep sticking it in the oven lol
My theory at least in my case is that the overheating loosens the connections over time and that causes the screen to flicker. That explains why when I bake it, it works the longest. The connections were "melted" back into place. Everytime the problem comes back the phone has been running extra hot.
If you try the soldering paste solution let me know how it goes.
My plan is to root my phone and do the temperature mod + the soldering paste. I'm having trouble rooting my phone for some reason tho.

That phone is done, I tried the heating with the solder flux and must have heated it too much because now I get nothing. This refurb phone I bought on ebay is rebooting on me now after a minute of use, but won't reboot if its idle. I'm trying to get it back to lollipop to see if it is the software but it keeps failing when using the LG Flash Tool, so I'm assuming I cannot but hoping I'm wrong. I tried the swapping out the batteries that I've been reading but that doesn't work.

Hi and thank you for checking my thread
I have a problem with my G3 as described in the tittle, I did the Paper trick I saw on YouTube but sadly it didn't work
After a while I found out that placing a piece cut from Credit card under the CPU might work and I did , but one week later I had the same problem, likely I can just click sleep button and it returns to normal
After these many problems I decided to give up on it and sell it, but I need a permanent Fix so I don't get involved in Cheating
Also , does replacing motherboard will fix the issue ?
Does G4 Worth it now ? I know about bootloop problem
Probably is a bad motherboard
When my G3 finally died (digitizer went bad), I just replaced it with a used G4 for $150. That was like 6 months ago. The phone has been phenomenal. I know there is many who say that every G4 will bootloop eventually, but I really don't see how thats possible if you just browse google for the issue. Yeah, a lot of people had the problem, but if everyone did you wouldn't see the G4 still being sold at a ton of outlets, and you would see hundreds of links to the issue. I think there was a large batch of them that were bad... and they got past QC, but the vast majority of them are probably fine.

Replacing the Motherboard will fix the issue ?
Yea, i saw "1 month/year after" Reviews on youtube and no one montion the bootloop issue, people ask them in comments and they reply that the phone works normal with no issues
Thank you for replying dude appreciate it
I was skeptical at first, but by baking the motherboard in the oven did the trick for me. It has been a couple of hours now an no flickering, no black screen and no troubles. And i know i'm asking for Murphy to come and bite my as*, but as a little trick, i'd like to suggest before putting the mobo in the oven to try something: i have an old Akasa X4 cpu cooler which has metal fins which are removable. I took one of those things and cut a square a little bit smaller than the power IC to the right of the SoC and then cut another one the exact same size then stacked the two one on top of each other, making sure to not short any capacitor around the IC and then put the metal shield back, making sure to put pressure on the IC. Then preheated the oven at roughly 180 degrees celsius, then put the motherboard SoC face up into the preheated oven on three balls of aluminium foil, one at the bottom near the micro usb, and the others to balance the motherboard, like a BMW Isetta, and put the timer for 10 minutes. After these nervous 10 minutes, I took out the mobo and let it to cool at room temperature for ~30 minutes. And voila, now it works. I do hope that it is going to last, and i will be very careful with this phone, unlike the previous owner. Seriously, how can you put a freaking button (small one, from a shirt) between the SoC and the mid-frame? Crazy. And that's why i got it for ~8000 JPY (about 70 bucks).

I had a similar problem for about two months. I tried the paper thing over the camera sensor and I felt like it helped some but the problem still continued. The screen would just slowly go dark with vertical lines running through it. All apps would still work in the background while this was happening. I could boot to TWRP and this problem never happened while in TWRP which was odd. Seemed like if it was a screen issues or hardware malfunction it would happen all the time. That's when I decided to just flash back to stock. I was thinking about getting the S8 anyways so what the hell. I flashed to stock 10B and took every single OTA. Took all night but I've been running stock for over a day now and the issue has not replicated itself one time since reverting back to stock. I was on RR Nougat and Fulmics when it happened prior. Has to be a root or Rom issue?

Just wondering if your G3 is still functioning without the issue.
It really feels like a hardware issue but as you pointed out it didn't happen in TWRP... but like many, I encounter the issue when the phone gets a bit warm (>35C), so maybe TWRP and your stock android is not as hot as RR Nougat? Then again, I'm on MM when this happened...
Update: Actually the flicker n fade happened to me in TWRP while I was backing up. The temperature read about 60C.
I had bigger problems with my g3 and they started as follows
Problem 1. camera not being detected and crashing. 2. Reboot once a while which got worse over time. 3. Bluetooth sketchy and WiFi not connecting. 4. Sd card being ejected and mounted constantly. 5. Mobile data stopped working.
Solution: baked it in the oven 10min with cpu side up at 185c removed to cool 4 30min. Problems gone for the meantime.
This morning at work my D852 died with the exact same screen fades to black and would only stay on for at most like 10 seconds and would only come on again after the processor cooled enough. I came across this youtube video.
https://www.youtube.com/watch?v=UF1s4RCZAvc
Since I didn't have any copper foil tape, I substituted with Aluminum foil tape and placed the tape in the same places as detailed in the video. (copper works better than aluminum for heat dispersal)
My phone is now back to normal and hasn't shown any issues with the past 5 hours since I applied the fix.
UPDATE: My phone has worked perfectly for several days now until I turned on the GPS from Cell Tower to High Accuracy and it immediately started to die again. Once it cooled down I was able to get to the settings screen to turn off GPS and it went back to functioning like normal
How to fix
I tried the paper trick and it did not work. No need to replace the motherboard or the phone. The issue is just a bad connection between the motherboard to the LCD display.. Probably due to dirt (in my case, I found that quite a few places in my motherboard had corrosion buildup). Here is the fix...
1. Remove battery cover and Unscrew The back plastic from the base of the phone to get to the motherboard.
2. Disconnect all the connectors from the motherboard.
3. Scan the motherboard for anything unusual. (My motherboard had corrosion on several different places).
5. Clean any dirt or corrosion with lint-free cloth. (I didn't have one so I had to use a Q-tip).
*if needed, Dip the cloth in rubbing alcohol to assist in cleaning. make sure that the cloth is JUST BARELY Damp and not dripping, otherwise you will risk water-damaging the phone. If you use rubbing alcohol, make sure that you dry the spot right after you wipe it.
6. Once you have cleaned the motherboard, check the base of the phone and clean any dirt from here also.
7. Replace the motherboard, re-connect the connections, screw on the back, and put the battery cover back on.
Viola! Mine has been working like new for 4 days so far with no issues...

So a permanent fix is a new motherboard or a new screen?
So, i first posted this issue on reddit, now i'm trying here for solution. First, sorry for my grammar.
Recently, i cracked glass and touch-screen on my LG G3, and repair was too expensive (at third-party service), so i bought used LG G3 with perfect display, but it has strange problem with bootloop. It's not the same bootloop like when it's battery issue. Sometime it freeze, and restart itself, but at LG logo screen freeze again, and it came to bootloop like 4-5 times, and after that boot normal.
After that sometime works normal, sometimes restart itself again after while, and bootloop few times, and than boot normal. It doesn't matter if it's on battery or charger, it will bootloop until starts normal. I didn't find any patern that cause to freeze and restart itself.
1. I tried to change battery, but that didn't solve the problem.
2. last night, i flashed v30B firmware (because it was v30N firmware installed, so i thoght that is causing bootloop).
I serched on internet, but didn't find anything like this issue. I bought 32GB version of phone (my was 16GB), so i'm trying to fix it to use of course, if i can fix.
Temperature is just normal, 30-40 idle, and 40-50+ if doing something.
I swapped my working MB into new phone, and that is OK, but i'm trying to fix this faulty MB on my cracked screen through the OTG cable and PC mouse. I'm considering to reflow chip to try that at least.
Any suggestion is welcome.

After that sometime works normal, sometimes restart itself again after while, and bootloop few times, and than boot normal. It doesn't matter if it's on battery or charger, it will bootloop until starts normal. I didn't find any patern that cause to freeze and restart itself.
1. I tried to change battery, but that didn't solve the problem.
2. last night, i flashed v30B firmware (because it was v30N firmware installed, so i thoght that is causing bootloop).
I serched on internet, but didn't find anything like this issue. I bought 32GB version of phone (my was 16GB), so i'm trying to fix it to use of course, if i can fix.
Temperature is just normal, 30-40 idle, and 40-50+ if doing something.
I swapped my working MB into new phone, and that is OK, but i'm trying to fix this faulty MB on my cracked screen through the OTG cable and PC mouse. I'm considering to reflow chip to try that at least.
Any suggestion is welcome.

If I'm following you correctly, you've swapped out the motherboard from your old phone to the newly purchased phone? If so, make sure you've reconnected the ribbon cables securely. If it is that you're experiencing the described problems on the newly purchased phone, it may explain why it was sold. But if that's the case it might be worthwhile to take the phone apart and check the connections as well. I'd bought a second lg g3 with the infamous screen flicker, fixed it by cleaning the connections with a small plastic bristle wire brush and a small bit of alcohol. If all else fails try new software. Hope that helps. You did say ... any suggestions welcome.
