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.

Thanks.
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, I just bought mine Nexus 5x few weeks ago, and 1 day after I started hear about the hardware bootloop problem. It made me scared.
I started searching about the problem and, until now, the conclusion about the problem is the phone gets heat and melt the solders of processor. That's a "comum" problem in LG phones, LG G4 have the same problem.
"-Ok, but, what causes that?"
My opinion, as lay, it is caused by cheap USB-C Cables and/or wall adapter. Fast charger adapters can also be a big problem. (Source: http://www.makeuseof.com/tag/buy-usb-c-cable-wont-destroy-devices/ and https://forums.oneplus.net/threads/in-response-to-the-type-c-cable-discussions.412344/ ) USB-C transfer a lot of power through it, accelerating the process of charging and, consequently, making phone hot. The poor solder who LG's did on the phone start to get melted with the time.
Prevention you can take:
You can make this test in first of all:
https://forum.xda-developers.com/nexus-5x/help/diagnosing-soon-to-bootlooped-phones-t3543830
1- Use only the original cable and wall adapter who comes with the phone
2- Buy only well constructed USB-C cables (maybe it means expensive one, but you will expend more money buying a new phone than a good cable)
3- Keep control of phone's temperature with some app ( I use Cpu Monitor) and never let it exceed 45°C/50°C. If the phone reach this temperature, turne it off immediately (more recommended) or enable battery saver mode.
If the phone suddenly get heat and turn off:
1- DON'T TRY TO TURN ON! Wait until it gets more cold and than try to boot. If it boot, try to make a backup of you important things.
1.1- If the phone is in warranty, send it back and they will send you a new one.
1.2- If not, go to step 2
2- You can try to fix at home. Here are some links:
https://forum.xda-developers.com/nexus-5x/help/rld-fix-red-led-death-t3541536
https://www.youtube.com/shared?ci=i6eu7OK_4t8
3- If it don't work, you can take the phone to someone who works with this and ask for him to make new solder for the CPU.
If anyone know more tips or even solutions, please, contribute to the thread.
**sorry for eventually grammatical mistakes**
Bad quality soldering is really a common problems. Most of my mobile devices - especially notebooks - died because of this. I guess everybody had the problem once where a laptop get bluescreens more often with time until he finally refuses to boot up. Usually, damaged solder connections from chips to the mainboard are the cause for such problems. The solder connection degrades due to thermal and mechanical stress. With time, more and more micro-cracks are emerging with the result that the electrical resistance is increasing. Thus, signal transmission is distorted and bluescreens or crashes occur more regularly until the device dies.
In fact, a thermal treatment can help! The idea is to melt the solder to gain a reflow of the solder which repairs the micro cracks. Although there are semi-professional reflow ovens available on the market, you wouldn't buy one just to repair one device. But you can try do this by using your oven in the kitchen, a hot hairdryer or (if available) hot air gun. The best procedure (independing of the used heat source) is to disassemble the device, detach the battery (!) and if possible remove plastic parts. If these parts can not be disassembled, you can protect them by wrapping them with aluminium foil (it will reflect heat radiation and thus prevent fast heating of these parts). The best case would if you just have the small mainboard with the soldered chips on it. The start the thermal treatment: turn your oven to max. temperature possible, wait until its pre-heated and put the device into it for around 2-3 min. This time should be sufficient to remelt the solder connection (and repair them) and short enough to overheat the plastic parts. If it didn't work, try again with about 30 s longer duration. If you use a hot air gun try to apply the hot air stream only the soldered regions. Usually you can see if the solder gets hot enough. If its working with a usual hair dryer? I dont't know..
I used the kitchen-oven procedure many times and sucessfully revived many notebooks...
I went to my technician already twice but the blue screen keeps coming back. I need to go back every week as the technician heats the soc with some paste I suppose. After one day of usage it goes back to blue screen then the phones becomes dead. Is there any fix for this? :crying:
Thank you for the help guys.
Replace the motherboard or heat it up with a iron
Motherboard is quite expensive. Do I need to put thermal pads as this heating method seems to fix the error temporarily.

Yes definitely try putting thermal pads or plastic. Heating the motherboard is only a final temporary solution, most useful for just backing up data off the device.

I don't know.
It might work for a long period of time, it might not.
If it works you can hope for the best and if you want to prolong the life of the phone, make sure you are not stressing the phone and using it while overheated.

One thing I noticed also when I did the paper trick by putting a piece of paper on the left side of the camera the phone works for awhile too. Any reason for this why it works?

The problem is caused by bad quality solder and a phone that tends to go very hot. If you use your phone often while hot, the bad quality solder with the chip mess up after a while and causes you to lose connection.
The pressure you're putting with the paper clip or plastic helps restore the connection by pressing on the chip.
Thermal pad is best since it helps with the cooling also. Avoid metal since they conduct electricity and might interfere with the radio signals.
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 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
Hey all, I have had my Galaxy Note 10 for almost a year, and the other day I accidentally dropped it and ever since then I have been getting the message that my phone temperature is too low and that charging would resume when my phone returned to a normal temperature.
So I did some research and found that my phone's temperature sensor is broken and that I would need to get the wireless charging coil replaced as that is where the sensor is located. I also saw that it was a cheap repair and would be covered by warranty. Unfortunately because of the root it would not be covered by warranty and was actually very expensive as the part needed to be imported.
I ran a few tests and apparently my phone is at minus 30 degrees Celsius. When I got a report sensor, it says that it isn't even there. Clearly the sensor is broken. (Look at attached URLs for screenshots)
The strange thing is though, that I can still use my phone whilst it is plugged in. So obviously it can still use power, but not store it in the battery. Because it can still use power and since it is rooted, surely there is a way that I can change the minimum temperature at which the phone can charge? Or delete the piece of software/file that gives jt any limit at all?So I wanted to ask, since my phone is rooted, surely there must be a way I can "override" the error and charge my phone regardless.
So I looked for ways to charge my phone regardless and came across thermal throttling, which I know is dangerous, but surely because my phone isn't actually "low temperature" if it was well managed, it wouldn't be too unsafe? And would thermal throttling even work as I know that it helps to run your phone at HIGH temperatures, but what about low ones?
So the last thing I wanted to say was that with the phone being rooted, is there some app that can allow me to ignore this warning (override it) as there is obviously a file that prevents charging when the temperature is low. Could this file be altered/deleted, or could the while thing just be ignored. Or would thermal throttling work?
Please leave some feedback, anything is appreciated.
Also please link at the attached URLs for screenshots.

If that's the only temp sensor for charging you should have it as it won't shut it down if it gets too hot.
A Li meltdown isn't pretty.
Is the bad sensor in the battery???
If so simply replacing the battery might fix the issue
What is the problem?

The repair centre that I took this phone to said that the MOTHERBOARD was broken. I think they were mistaken as this is not a problem caused by broken motherboard. Research says the sensor is in the Wireless Charging Coil so I might try fix this. but then what is it about the battery? Which part is broken?
And in the meantime is their any way to override this message with a rooted phone (my original question)
It a thermistor on the wireless charging module or a bad connection going to it. A broken multilayered mobo solder trace can be repaired if it's just one trace and it's beginning/end point isn't under a flat pack.

So are you saying that either the connection (on the wireless charging COIL) from the coil to the battery is broken, or the connection port on the battery might be broken? Is it definitely NOT a motherboard issue?
If so does the wireless charging coil/entire phone battery need replacing?

I don't see a listing under sensors for a internal batter sensor... it appears to be external.
I didn't tear it down.
The sensor or connector issue is more likely but not guaranteed.
You could take an ohmmeter to the sensor to check if it's the culprit. It appears to be on the charging coil assembly, right?
If so a cheap fix.

There is only one sensor and its attached to the wireless charging coil, that was the case with the s7 edge back in the day. I see no reason why that would be different now. Its purpose is to monitor the battery and coil temps.
Replacing the wireless charging coil should fix it. You should be able to order one for pretty cheap. its could also just be a loose connection. If your warrenty is void then you might as well open it up (if you have the tools and skill) to confirm the wireless charging connector is seated properly into the motherboard. (since you dropped it, its likely its just come loose)

This could be true if the service tech was mistaken. All the OP knows for sure is the chipset isn't getting the temp data.
A good repair center -maybe- could do mobo level repairs. Sammy certainly could.
Remember no repairman likes an open box special.
The OP can try replacing the coil but maybe no better off if it needs a mobo. In the back of my mind I still wonder if the battery pack has a temp sensor the phone is using as well. I see no indication of that but it seems like a logical place for it especially given Samsung's history of exploding batteries.
If the OP goes for a battery replacement there's much more risk of damage involved.
Tough call.
Note: A high G impact can even break internal IC connections. A 3 foot drop onto concrete can generate sufficient G loading to do this. So there's that...
A good case spreads the G force loading over a greater timeframe and lessens it by absorbing some of the energy as well transforming it to heat.
These are heavy, expensive phones with very little impact protection. Get a good case like the Bolt.

If that's the only temp sensor for charging you should have it as it won't shut it down if it gets too hot.
A Li meltdown isn't pretty.
Is the bad sensor in the battery???
If so simply replacing the battery might fix the issue

I believe the sensor is on the wireless charging coil
Guys had the issue back on the s8 too

It be a happy ending if so...
and not the first time a repair tech was wrong.
Maybe the OP could try a better repair shop if they don't feel up to using a heat gun and popping off the back panel. This is one of the easiest repairs for these phones but still requires considerable care to do. Depends on the OP's skill level and having the minimum tools required.

Don't know if this will help but I have the same problem with my Note 10+. Mine has a cracked back cover and the faulty temp sensor issue seems to emanate from this because as soon as I slapped on a back cover, the issue resolved itself. I'll replace the back cover eventually but it seems the loose panel might be the issue.
Good luck.

Welcome to XDA
There's a temp sensor on the wireless charging coil assembly I believe. There are a bunch of ribbon cables as well, one could be loose or damaged.
Rear covers are cheap, replace it before the phone gets severely damaged. Get a rear cover seal too. Water kills phones.
Always keep the N10+ cased or it will get damaged. The Zizo Bolt is cheap, provides excellent drop protection and makes the N10+ easier to use.
Have had reboot issues for a while now and they were just getting worse. Nubia said to send in for out of warranty support, but thankfully that process is severely broken as all of the repair contacts they forwarded were either out of service or foreign language (Czechoslovakian!?).
In any case, I figured the phone was done so decided to take it apart and lo and behold, it seemed to last a bit longer between reboots when the back was off. Assuming it was a heat issue, I tried replacing the thermal paste where I could with varying results, but ultimately I ended up taking it completely apart to access the face of the SD 888+ chip and replaced the blob of pink goo covered with copper tape with a 1.5mm copper shim along with MX-4 paste. 1.5mm seemed to be the right spacing and the 15mm by 15mm shim I had only needed a few edges reshaped to fit within the housing.
So yesterday I put it all back together and no hint of issues yet. Longest time it's run without a reboot for at least a month.
I suspect I may have accelerated the breakdown of the cooling since I often put my phone into a bicycle mount which I think puts some pressure on the back of the phone, likely squashing the paste a little flatter each time till it was no longer making contact.
Anyway, if you do start seeing random reboots, this might be the issue.
Though it feels like I'm talking to myself on this forum. Are XDA forums not what they used to be or are Redmagic phones just not as popular as my Google feed is leading me to believe?
If you're using it in direct sunlight you aren't doing it any favors. You can fry a phone like that rather quickly. The thermal shutdown may not react fast enough to prevent hardware damage...
Limit SOT in direct sunlight to seconds not minutes especially in high ambient temperatures.
Monitor battery and CPU core temps.
If the phone feels hot, it is hot!
