If you have a bootloop when you turn on the Wi-Fi or Bluetooth, (this will void your warranty and do it at your own risk)
please Check if1)
I can't even turn on the wifi then, go to cpu-z (be sure nothing working other than cpu-z) check your CPU0,CPU1,CPU2 and CPU3.
If: Cpu0 is always at highest usage(2400mhz or 1750mhz)
This means some protective software in the phone that doesnt let you turn on the wifi,
REASON: There is a hardware issue in your phone my theory is that your phone got extra hotter. If you have a clean booting and you read 78 degrees on cpu-z i think you fall in my line. All the tips given will be on my theory and its set of properties.
WE CAN BYPASS THIS SOFTWARE PROTECION: turn off the phone take out battery and get it back turn on. Now you by passed this software lock, and wifi and bluetooth is turned on or can be turned on BUT: AFTER SOME MINTUTES YOU WILL GO INTO BOOTLOOP. To fix all you need to do the thermal mode.
This software proteciton causes battery drain: http://i.hizliresim.com/A3ojRr.png

http://i.hizliresim.com/vZ03kD.png
SOLUTION:
Open the phone, apply a good quality thermal paste.
I did this and it worked. My phone didnt bootloop. and my temps were exteremly lower. i could get 38C on idle.
Don't get a new battery: it is not power related. i get a new battery(original) it didnt fix it. it is all about Xtreme Temps.
DO'S AND DONT'S
Do not: Buy a very cheap thermal paste. (why: i did it 40gr for 2.5 dollars seen as video, it fixed it but after 5 days my phone get the bootloop again and when i opened my phone: the Thermal paste was STIFF as ROCK i had to cut it with scissors. no jokes. buy Zalman sth like this mine was branded as: Silicon Thermal compund all white very cheap)
Do not: apply too much paste edit. Use a lot. There are lots of gap between soc and screen side. You have to apply a lot paste igrone this lol. Use a lot paste
Do not: use a copper shim unless (you can make an accurate calculation of thermodynamics of your phone by calculating the energy produced by the SOC, heat transfer rate "c" of the glass and the plastic within and the copper shims actual thermal transfer capacity and the paste you will apply. this is complicated stuff and it is always impossible to have your theoretical values being equal to experimental values)
Do not: overclock nor disable the thermal throttling.
Do not: talk bull crap on : applying thermal paste will actually burn the screen stuff, its illogical and impossible. I have had my screen WARMER when i didnt have the thermal mod on, really here is why(HEAT PRODUCED BY THE SOC IS ALWAYS SAME AND THIS VARIABLE IS ALTERED BY THE CPU CLOCK. IF YOU DON'T PUT A HIGH THERMAL CAPACITY PASTE/TAPE/SHIN, the HEAT TRANSFERRED AT A PORTION OF TIME is let's say t. and the total energy(heat) caused by SOC is Q(this doesnt change nomatter what you apply it is only about the CPU CLOCK). so Q/t will give you the what is the heat getting to screen over the portion of time t. However, what people think and assume, if you apply the thermal paste, the heat will transfer to screen and make it burn: here is why its bullcrap: if you add a layer or thermal paste: This will not change Q, but it will reduce the portion of time that is showing how many joules you are transferring(dissipating from SOC to Screen side) . so after applying thermal paste let the t be= T whereas T<t, so T is a smaller value than the t. Q/t is a bigger amount than Q/T, here is why (if you divide the Q over a smaller portion this will increase the proportion.) what does Q/t or Q/T gives us? the heat transfered from SOC to SCREEN SIDE over a portion of time: or how many Joules you dissipating from CPU in 1 second lets say. since you transfer heat FASTER, does mean CPU will be COOLER and SCREEN wont have MORE HEAT COMING TO IT. NO: VERYWRONG!!! IF the cpu is cooler after the THERMAL MODE: this is actually good for the screen since when you dont have the thermal paste CPU IS LIKE 60-78 C DEGREES WHILE USING AND AFTER THERMAL PASTE THIS IS 52-63(MY RECORDS) This decrease means the Screen will be cooler to. Think the Screen as a part of the CPU, if Cpu is cooler this means Screen is cooler too beacuse IN THE FIRST PLACE screen is HOT BECAUSE THE CPU IS HOT)))
Do : Buy a good known brand of Thermal Paste or Pad that is not conducting electricity.
After applying the thermal mod, My bootloop is cured as well my cpu was cooler.
In physics we know that, (resistivity) if Temperatures increase, the circuit becomes more resistive. It's not due to enlargement of metal materials due to heat. To further understand the issue please www.youtube.com/c/michelvanbiezen go to Resistivity under Physics Electricity
So a cooled down cpu is known to be more conducting. but i dont know how it affects the speed, so i can't elaborate about the speed afterwards of thermal mode.
do it at your own risk and IF: YOU HAVE THE SAME ISSUE WRITTEN AT THE ABOVE: CPU0 ALWAYS AT 100% and I CANT TURN ON THE WIFI:
Can you guys provide or give some steps how we can manage thermal issue on LG G4 ?
Will thermal paste or thermal pad or thermal tape works on lg g4 ?
Will putting copper tape above CPU will reduce thermal problem ?
I think by managing heat , we can prevent our device from getting bootloop .
Any tips from the users are greatly appreciated.. Pls take part in this thread
Thanks

I did a teardown guide in the sprint threads over a year ago how i pasted mine and it stay a little cooler but my g4 is nearing 2 years old give or take. And still runs decent. I use it pretty hard for vr apps and stuff like that. But i used artic silver on most flat chips on both sides of the motherboard as well as a copper shim on the cpus
---------- Post added at 11:32 AM ---------- Previous post was at 11:29 AM ----------
Ive been sayin all along i think the thermal mods have helped keep mine alive. Also living in a colder climate than most i think helps. Its still 70s in the day and 30s and 40s at nite. Here in vermont. I get like 4 or 5 months this year of decent weather. It snowed 2 weeks ago. Didnt acculate but did snow i think that helps
my manufacturing warranty expired on march. i also was wondering if i should do something to prevent heat. mine gets to 111F then i let it cool down... would be nice just to help it run cooler..

By just turning on wifi and opening any webpages (Forget gaming) mine increases to 120 F -125 F. So I'm very much worried about heating issue. Gonna try ur Arctic Thermal mode ..
I'm thinking of putting thermal paste in all 5 chip like you mentioned and cover it on top of each chip by thermal tape made up of copper.. A sandwich of thermal paste (Arctic 5) between chip and copper tape (Thermal tape). Do u have any idea will it do some magic...?
My g4 is usually always in the 40-48C range when being used. Today it reached 52C , i was playing Pogo and it was a hot day. Mine has consistently run hot since I got it back from boot loop repair.

just feeling the device no it dissapates the heat out better but the screen and battery always feel warmer which mean its working i guess i also have my 2 big cores shut down with kernel manager to try to help just in case the only time my 2 big cores are actice is when booting and recovery and such but as soon as device boots they shut down.

Hi all.
My LG G3 (stock 6.0 V30n) keep rebooting while I'm using it. I tried the thermal paste mod as suggested in this forum but the situation did not change. Also Wifi and bluetooth do not turn on at all.
I tried a repair center and they said that a new motherboard was needed (price for the spare parts + service = 170$). I did not proceed as I can (easily?) order a spare part and change it by myself for much less.
I already tried to change the battery (bought a new LG-made one, produced in 2016) but this did not solve anything. Also I tried with various factory reseted, cache cleans and even with the latest LineageOS.
Do you think that by changing the motherboard I would be able to solve these issues?
Thanks!
I dont know about this issue, however my thought is that maybe from past overheating perhaps RAM chip or SSD has some poor solder connections. Maybe you could try putting something onto those 2 chips to press them more firmly to the motherboard/soc.

I already tried with a slice of a credit card, plus I put aluminium foil and thermal paste on the CPU and Wifi chips, still reboots
Have you tried putting some pressure on the rear camera connector as suggested by some? If you did, I guess you can try to apply heat to the whole motherboard. I wouldnt bake it. I think you could use a candle to heat it up, while at the same time applying pressure somehow (be creative lol) so that RAM or SSD doesnt fall off.

Unfortunately heat damage to micro soldering joints are usually non-repairable. The silver-based lead-free micro soldering used on it is difficult to repair and it's usually more time and cost efficient to replace the board; that is, if heat damage is causing your problems. I've heard of people actually baking their mainboard in an oven to repair solder joints. This is a ridiculous myth and you risk damaging it further. :silly:
Also, aluminum foil will have the opposite desired effect on heat dispersion. It is not solid and will end up doing nothing, or heating up the chip further. Also, thermal paste in not a good idea to use for this application. Thermal paste is best suited for high-heat CPU and GPU applications. It also expands and hardens after heating up. It may be too late for your device, but for others who are interested, you want to use a 15x15x0.5mm thermal pad. See this post and this post for more information.

Aluminum foil WILL help, not as much as a solid piece od metal but it will transfer heat to the frame of the phone. In my case RAM is bent around the edges because of overheating and it lost contact to the soc. I fixed it by cutting a piece of thin metal I had so that it almost reaches to the side edges of the frame and about 15mm in width. I put thermal paste under it and 0.5mm pad on the soc and now RAM is forced to contact with broken BGA because of the pressure. That fixed the screen fading/flickering as well as overheating. The CPU now idles at around 34c and stays below 60c on most games with some undervolting.
With that said, maybe the same principle could be applied with other chips that cause issues.
Hi all,
Firstly apologies for the long post but I feel the more information I can supply the better diagnosis might be made.
I was recently given an LG G3 D855 16GB/2GB phone which has a very intermittent issue of rebooting and throwing a blue screen, notably it seems after I run any app updates. I have so far done the following to try to fix it:
1: I managed to get it working long enough to get all my friend's pics and movies etc off, then performed a factory reset using vol down and power button. Phone booted up fine, I could proceed through the setup options. Took it to work and using LG PC suite upgraded to Marshmallow. No issues.
2: Updated two apps from Playstore, rebooted and got a blue screen and reboot, but eventually it came right again and I was able to use it for a while.
3: Ran another update from Playstore and got a blue screen before the update was even installed. Left it alone for about an hour with the battery out then booted up and did a factory reset again with back buttons. All good, ran through setup no issues.
4: After using it for a few days I decide to try to update again, and again blue screen and reboot. This time did not come right even after leaving it.
5: Downloaded KitKat TOT and DLL files for my specific area or zone, South Africa, and managed to get the phone into download mode then used LG Flash Tool v 1.8.1.1023 to install ROM from TOT file. All went well. No issues at all.
6: Used for about a week then upgrade to Lollipop via LG PC Suite. Again, no issues whatsoever.
7: Next day decide to do updates, updates went fine until I rebooted then blue screen, followed by green screen with the demigod kernel crash message and reboot. However, I just left it to do its reboots and after about 5 or 6 times it booted up and stayed running.
8: This past Monday I upgraded to Marshmallow using LG PC suite, no issues whatsoever.
9: Yesterday I ran one update and rebooted, blue screen and rebooting. Took battery out and left it for about an hour again, put battery back in and did factory reset using back buttons.
10: As of right now phone is functioning perfectly again.
I must mention the following:
1: I can install any app that gets wiped when doing a factory rest, like WhatsApp, Nine Email, GBoard etc with no issue whatsoever.
2: The battery is fine as far as I can tell, it lasts about 3/4 of the day under normal to heavy usage and is not swollen at all.
3: The Phone NEVER gets hot at the back, even when rebooting constantly or throwing a blue screen.
4: As far as I know it has not been dropped.
5: It is protected by the LG QuickCircle case with QI charging back.
My question after all this is, could this be a hardware (Motherboard) issue or is it software somehow? I really like this phone when its working correctly so would love to be able to use it with no worries.
Any guidance at all from the wonderful smart people here at XDA will be highly appreciated!
Thank you for your time and patience!
Blue screen is, I think related to SSD losing some contact with motherboard. You need to open the device, get the motherboard out and put 0.5 mm thermal pad on the SSD (under the EMI shield) and put the shield back. Then take a 1mm thermal pad, or 0.5 depending on your preference but I highly recommend a 1mm one to reduce the risk of running into screen fading issue, and put it on the RAM chip. Put everything together and screw the upper screws tight so that pressure is made to the chips.
You can also apply heat to the chip beforehand, while applying some pressure. In that case, I recommend you to put something on the other side, on the RAM chip so that on both chips pressure is made while the heat is being applied. You can use hair dryer but shield the rest of the boad with some aluminum foil. Try only the thermal pads first tho.

Hi and thank you for your reply. I hear what you are saying about the SSD but my question is why only very erratically and why only when I do updates? The phone works flawlessly with calls, watching movies, doing email, using WhatApp. The ONLY time I have issues that I can ascertain is when I do updates.

I suppose because updates require a lot of storage I/O so it heats up more and that causes the solder to expand enough to trigger the cracked connection to do its job lol. It also heats up the CPU more than updating system over PC. Thermal pads are cheap. You can, however use aluminum foil just for the test but thermal pads are safer to use.

Hi and thanks again for your reply. Well, I can tell you that it is getting worse, I had random reboots and one or two blue screens for no reason, other than just normal usage. I went to the link you provided but the links in that original post to the images no longer work, however I did find the images so just need to ask, what you refer to as the SSD is that the Sandisk 16GB SDIN9DW4 memory as in the image attached?
That is correct. It is an emmc 5.0 spec. Remember to put pressure on both sides of the board (on ssd and ram)

Yeah you can cut it in the size of the chip but it doesnt really matter as long as it isnt smaller than the chip. If you have aluminum foil at home you can try with that first. Fold it a few times until it's thick enough. Just put some tape over it in case it touches the motherboard so it doesnt short out.

Disassembling the G3 is very easy. Check the guide on youtube and you'll get the motherboard out in less than 5 minutes. Just be careful with the ribbon cables. You got two on the bottom and two cameras at the top. I recommend you to try doing this before buying thermal pads just in case I was wrong and the issue is something else.

Well it seems there is a deeper issue with this damn phone!! I finally got the thermal pad, Artctic brand, 0.5mm but as soon as i apply the pads to the areas described and tighten up the phone simply refuses to switch on at all!!!. If I remove all screws from the upper frame and then try to switch on it does and blue screens immediately. So I'm thinking I just need to suck it up and get a new motherboard.
Thanks to all for the help with this!
EDIT:
Seems I had to leave it for a while, as it is now switched on and booted up no problem, with pads in place and screwed down. Minor issue now is it won't read the SIM card but I have also found a fix for that. Right now I'm running updates and so far all good, no blue screen yet. Will post back on Monday after I've used it for a bit.

If the pads dont work well enough, you can take the motherboard out, remove the metal shields and take some hard flat metal pieces that you can put on both ssd and ram (big enough to cover them), then put some aluminum foil big enough to cover the motherboard (to protect the rest of the board from heat) and take something like pliers to put pressure on both of the metal pieces (aim for the middle of chips). Then take a candle and concentrate heat on both chips. Switch sides every now and then for about 5 minutes. This is how I fixed both reboot and screen fading problem atleast temporarily.

Hi, thanks for the reply. No, the pads are working fine, so far, just that I had to loosen the lower screw on the volume/power panel in order to get the SIM card to read. But otherwise so far so good

Hi I would just like to post an update to this,. After much battling I have finally managed to get a working phone that seems stable so far after 4 days. I'm using a 0.5mm pad on either side as the phone simply will not switch on with a 1mm pad on the screen side. Also, I had to screw down the screw I loosened at the bottom of the volume rocker/power assembly, the SIM card is still working however the SD card no longer reads but that's not a serious issue as the phone has 16GB onboard and I'm not using it for major games or movies or anything like that, purely for work email, calls/SMS, WhatsApp.
So here's hoping it will now continue to work and i will post here regularly with any updates and/or issues if that's acceptable to the moderators.
Bare in mind, all of these fixes are not permanent, for a permanent one you need a new MOBO
I've heard it is.
But with it, 2 more questions arise, since i've seen people claiming it's the RAM problem, others saying it's the CPU. Nobody seems to agree on what's the actual problem.
So, I tried ironing the G4 over the RAM, around 230°C for 3 minutes, pressed on it a bit then let it cold. Proceeded to put folded aluminum and Artic MX-2 thermal compound so it would make pressure on it but also transfer heat okayish.
I've had random reboots but apart from that it's working.
So here is the thing, if i send it for a reballing of the RAM (obviously good lead solder) will it work with no problem? Or do i need to reball the CPU instead?
This because im not wasting any more money on this device only to fail again in a near future.
What do you guys think?
Its both. Ram sitting over CPU. CPU solders are actualmprobkem though....caused by poor soldering
Don't bother. The solders points are do tiny they use a computer not hand

So in theory reballing both CPU and RAM would solve it? Or is the CPU itself which doesnt work properly?
I know people who have the proper tools to work on small components, i just dont wanna spend on it if even after reballing both turn out the CPU is actually bad like on those nvidia 8800 GTX, which failed anyway after reballing, turning out the problem wasnt the solder but the actual GPU which killed itself.

The actual problem is to o components sitting on each other causing excessive heat. Its not a defective CPU or RAM chip. I've seen a video on YouTube where a guy places a thermal paste pad and never has issues again
I'm not isure if it us the actual solder points get screwed up because my device has never looped. You'd have to ask someone to show you pics after a bootloop. But then again if a person was able to fix it with a thermal pad I don't think its the solder points but rather putting something that dissapates the heat off the chips
You cannot mimic a solder point like this. Its too small. Expect to get no guarantee that the solder point will last
Anyone will tell u go get a board or another device. Only people that actually do small work like that are Chinese (not being racist) in my area atleast that have a lot of expierence in fixing electric components. They never guarantee their work though because the work they're asked to do they know they can't mimic a robot
For the money you spend trying to solder you can probably get a new board these days. Mine is a pre release. It has 2gb of ram instead of 3. So did it loop? I don't know. LG doesn't acknowledge it as a loop. They call it a power failure. Does it mean bootloop? Its possible. I'm kinda confused about my phone but I've never seen the axtuql bootloop. Just not being able to power the phone on. No one has a 2gb ram G4 like I do. Did they replace the ram? Beats me...but I can tell you no one else got a G4 with 2gb ram from LG back.
Sorry if I confused you but I meant its the heat and overlay of ram and CPU that causes the problem, whether it actually screwed up the solder points I'm not sure

The actual problem is to o components sitting on each other causing excessive heat. Its not a defective CPU or RAM chip. I've seen a video on YouTube where a guy places a thermal paste pad and never has issues again
I'm not isure if it us the actual solder points get screwed up because my device has never looped. You'd have to ask someone to show you pics after a bootloop. But then again if a person was able to fix it with a thermal pad I don't think its the solder points but rather putting something that dissapates the heat off the chips
You cannot mimic a solder point like this. Its too small. Expect to get no guarantee that the solder point will last
Anyone will tell u go get a board or another device. Only people that actually do small work like that are Chinese (not being racist) in my area atleast that have a lot of expierence in fixing electric components. They never guarantee their work though because the work they're asked to do they know they can't mimic a robot

I've seen these small components get their solder balls replaced, it requieres skills but it can be done and as i've seen it thats why im confident on it. But yes im aware it could also go wrong.
I've been thinking and im also guessing it could be flexion damage, like the iphone 6. As the G4 is curved, perhaps a motherbaord screwed too tight, combined with use and heat could be the cause of it bootlooping, hence why it sometimes works again by putting pressure on it.
Actually i made some kind of small 'heatsink' out of folded aluminum foil, compressed it while heating it @ 200°C to get air bubbles out, and used thermal compound so that thingy both makes pressure on to the chip and disipates heat. Worked fine for 4 days then its back to bootloop again.
Thats one odd G4 you got there. I wouldnt mind at all having even 1 GB of RAM if that ment the device is working properly.
You are making me realise im better off buying a new board then putting in those mini cooper heatsinks.
tbh im struggling right now with moneyz so its fixing this, or buying a screen for either my Xperia Arc S (which is slow af thanks to google play services, but cant use any app without them) or for my Moto X 2013 (which looses phone signal when it gets hot until you reboot, also NFC chip doesnt work).
Repairing any of those would cost me something similar so i guess im better off with a new board. You know any trusted seller on ebay?
And thanks a lot for the help :highfive:
I guess by seeing videos they always heat the CPU and the solder points start working again
My phone and ram is just a mystery.
Because they're both right there.... Maybe either one can go. But I always see the CPU getting heated.
I love how none of the videos tell you or show you how easy it is to melt the chip using a blow dryer. Lol

Alibaba or aliexpress or eBay. I'd ask the seller for serial boars number. You know its likely good if it starts with a 6. Even better with a 7. If your lucky you'll find one with a 4 like mine....
810 board with 811 T-Mobile software. Takes custom Roma that are aosp based but not lg based....which doesn't matter anymore because lg based ROMs are lollipop based and were at Oreo now.
I don't really have problems with having 1gb ram leas. But occassionaly my phone will become sluggish if I open like 30 things

Heres mine
Also i'd like to keep all my camera's capabilities so no custom ROM for me.
But yeah i went to some sellers and asked about their motherboards serial number and see if at least i can get a 60X
Seems like the only way to get a working phone.

Some camera apps are pretty good much better than the stock google camera...users have discussed options in AOSCP thread. But yeah u won't get raw capture with them
Don't bother with serial number starting with 5 they're older motherboards...5 being 2015...when they first came out. 6 2016 7 2017
I can't stand lg stick software its so ugly would of never bought phone if it didn't gave ROMs.
I have two extended batteries and wall charger so I swap out batteries instead if using USB charger...if it wasn't for thus I'd likely be using another phone

mine is a 509 so yeah i wont pick those.
I mean with the G4 i use the stock LG camera app, not the google camera. LG Camera app on original signed firmware gives best quality imo. I have no problems with LG UI so ill keep it. And yes battery life is a pain but meh hehe, tbh my standars right now are so low that id forgive any flaw if i get a reliable working phone and not one that randomly restarts and bootloops-
So well yes i'll try with a new motherboard, preferably 70X and put a thermal pad on it right away. Thanks a lot for your time

Don't touch the new board
I get 27 hours on my extended batteries

ok you got me at 27 hours lol
but why do you say i shouldnt touch the new board? if its bad thermals what cause the issue in the 1st place

Stop focusing on what is wrong with old board and don't try and fix what isn't broken on new board.
Its a rule
Power bear 5000 mah battery

fair enough, but its engineered in pretty much the same way inefficient way as they've been doing it since the G3 which also had this problems, so honestly with this phone im not taking any chances, ill just put a little thermal pad and thats all ill do.
that battery requires calibration or just plug n play?

Was scrolling through my old posts and figured it may be interesting for you to know this.
I baked the SoC with an iron, worked fine for like 2 days, then bootlooped again.
I was broke so I sold it for spare parts rather than getting a new board.
Kinda regret it ngl, but man, battery life was absolutely terrible. Had to charge it AT LEAST, twice a day, and my Poco F3 could go on 3 days if I administered it well, and doesn't heat up.
As of right now, while I have a Poco F3 as mentioned, I have to daily drive an LG G3, for which I am also struggling because it's using Android 6 and some apps I need are not compatible, and I'm struggling to flash a ROM on the verizon version... just troubles over troubles with LG...
same ol', same ol'.
