Blue screen after serious slow down - G3 Q&A, Help & Troubleshooting

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!

hardware fault dead in under an hour

Well I'm disappointed!
phone arrived Yesterday. Worked perfectly whilst I added all my personal details then I decided to install asphalt 8, just to see how it performs (I don't actually intend to play it - can't stand the pay to win crap), and the phone made a nasty crackling sound and froze on the menu screen.
Powered down with power button, and on restart the screen is messed up with multi coloured lines running across it in various places. Then freezes, and reboots to repeat the process,the lines appear in different places. Sometimes makes it into the os, sometimes show the android error broken robot icon.
I'm guessing some fault with the graphic chip.
Luckily I bought direct from amazon so they are sending a replacement, but I have lost money on next day delivery, plus however much it costs to send back the phone (I'm in the UK but bought from mainland Europe) also not pleased my personal details are still on the device. At least I didn't import it from China.
Hopefully my phone was just a rare dud, and the replacement will be fine, as I can't find any similar reports online.
Anyone else had similar problems?
Yeah I would say that's a faulty unit. Sending it back is the right thing to do. Hope you get your money back

Well the replacement is great so far.
I noticed before the 1st one died that it was getting pretty hot on the back at the top, whilst simply going through the setup process.
The new one has been cool throughout setup, charging and about 3 straight hours of webbrowsing, so maybe the heat issue some are reporting is related to the hardware issue that killed my 1st one.
It does seem that quality control could be lacking, but as long as you buy from somewhere that offers returns, then i think its well worth buying.
I have just been using it as a mini tablet at home until i get a case and screen protector, so i dont know what the call quality etc is like, but battery on wifi has been pretty good.
Also, i charged it fully 3 days ago, and then left it on standby with wifi turned on and didnt use it. This moring it had over 80% battery, so standby time is much better than my s4 mini.

What is dying? Display or graphics chip?

Hello guys!

I'm here to report a sad thing that is happening to me. I'll try to keep it short.
I bought my Zenfone 2 64/4 and got it by first days of october. It's one of the best and fastest phones I've ever used. I noticed the display came defective with the lower left corner a little dimmer than the rest of it, but I couldn't care less because increasing brightness would solve my problem. The bad part was on about december or january when I dropped my phone, I did drop it twice: it slipped from my hands the first time but it was a light fall of like 30 cm; and the second was from greater height and so intense it got scratches on the back cover and the frame, (the impact was on the case and it got no scratches, none at all, like ZERO) but the screen remained intact.
After that second fall, maybe a couple of weeks later, I started to notice a weird color "seeping" and some vertical lines. The screen tarted to look like a painting on a canvas which got splashed with water and the colors started to "fall" and merge with the ones below.
I've been living with my screen like that for like 4 months now and no problem at all, I was thinking about buying a new lcd replacement. But wanyway.... now for the important part.
Problem
________________________________________
Now, after I opened my phone and tried to "connect" the loose cables from the screen (after an impact, it's possible the cables to ge loose), noticed that the screen didn't get better and that problem was not going to disappear. After a failed attempt to repair it, I sealed the phone again and some days passed (like less than 4). Suddenly, I notice weird glitches on the screen and uninstalled CyanogenMod 13 and reverted back to ZenUI, since I though CM 13 was causing the graphic glitches. After restoring ZenUI, I notice the glitches are still present and it's driving me crazy. It only happens on a certain portion of the screen, the top of it is working correctly. Aaaaand, to feed my paranoia, I've seen picture on Google of dead graphics cards and those weird glitches are similar to mine
TL;DR
________________________________________
I am scared, I want the problem to be the screen and not the GPU; if it's the GPU (or CPU), I am screwed. This phone was supposed to be my girl's gift after I got an LG G4. Gonna upload a video later, so you can see the problem. :crying: :crying: :crying: :crying: :crying: :crying: :crying:
Why don't you submit you Asus at service center ??
I don't think they will ever help me since I rooted my phone and installed CM. Void warranty.

Flash the black splashscreen zip through whichever recovery you use first in case you still have the white asus splash screen indicating your bootloader is unlocked. Try and flash stock rom on your phone and remove root through Supersu app after this and hope they don't check if your bootloader is unlocked as that's what counts. Take it back to the shop. All the best

Actually, I don't have an USA address. ASUS loves USA but not México nor South America. Bad luck for me.

Here's a proof that this display is acting B-A-D-L-Y.

LG G4 (TMO H811) just up and died

So yesterday morning, I was going to put my phone on my wireless charging pad...nothing new in the mornings. I set it down, the notification led on the pad came on and the LED light on the phone came on. Within two seconds or so, the light on the pad started alternating green/red and the phone LED just went off. The phone instantly powered off.
I was not able to power it back on, full reset the device, nothing. A new battery didn't fix it, unit was not seen by my computer....it's dead Jim.
I talked to LG and they said it was a bootloop issue with the V1.0 hardware. I told the lady that it was not bootlooping...it would not power on at all...period...zilch...nada...nein. She said it must be a different issue and that since it isn't bootlooping, I must have gotten it wet (both the phone and battery moisture sensors are solid white) and that it fried the internal circuitry. Awesome troubleshooting there LG (morons).
I called TMO, they are exchanging it for the $20 replacement fee. All is well in the world I guess. I have seen and read a lot about this issue and figured I was just one of the lucky ones that didn't have a bootloop issue. Something bit me though.
I have 2 lg g4 h818p ...one each for my wife and I.
Both of them had the motherboard conk out and replaced within the first 6 months.
They just went dead (at different times obviously ) , glad the sets were under warranty.
Hope the replaced motherboards don't have the same issue down the road

I've seen a few like this. Emphasis on few.
No boot loop so does not technically qualify as bootloop but otherwise dead and unrecoverable.
That too with no fiddling as you can't fiddle around at all with MM.
Like its bricked but you did not brick it.
Something bit me though.

Your backup routine will be more regular ?

Second Pixel C with same issue - backlight stops working.

I am on my second Pixel C where the backlight has stopped working after a month. The screen still works, if I shine a light at it just right I can see the contents (especially when they are white), but the backlight just doesn't come on. The previous one did this on and off for about a week while waiting for the replacement, meaning it would occasionally come back on and work for a little while. But, right before the replacement arrived, it went off and never came back on. My replacement did it for the first time today (it is one month old now), I connected to my laptop when I got home and issued an "adb reboot", and it appears to be working again. I have requested a refund from Google, but they said they couldn't authorize it, so I have filed a dispute with my credit card company in order to get my money back.
Overall, I like the device. I have had to work around a few of its shortcomings, but everything was satisfactory. I just can't keep replacing something every month.
Has anyone else experienced this? I mean, I know how to search and have found similar reports, this exact issue. Where the screen still comes on and is visible under the right lighting conditions, but the backlight is just non-functional. If so, what was the recourse you took to solve it? I have tried not putting it in my case (thinking that was the problem), rebooting (which occasionally has worked, but not always), factory resets (real tough without being able to see), plugging it in when malfunctioning, leaving adaptive brightness disabled, cursing at it and throwing my hands up in the air in frustration, etc. Nothing reliably works, and now I am afraid to let it go to sleep seeing how it came back after the reboot today.
Thanks for reading this...
My Pixel C started doing this last week. Wasn't so bad at first, but it's slowly gotten worse and starting last night the backlight will go hours without turning on. I've tried charging it, hooking it up to my computer, and just finished a factory reset and nothing has worked. Just like you if I shine a light at the right angle I can see things, but that's not exactly fun to do. Bought it at the end of March, so it almost made it 4 months.
One thing I should add, and this is probably a coincidence, is it started happening right after I downloaded the July updates. I only mention this in case someone else has had a similar experience.
My second one had gotten even worse, the screen sometimes comes on now, but the right half is either just fuzz or completely distorted, and the touch screen is non functioning.
I have ordered a Samsung galaxy tab s2, and will get my money back either from Google (doubtful), or my credit card company. Hope Samsung updates it at least to N.
I'm so torn, when it worked the pixel was awesome, I love the screen, closest any has come to the ratio of my camera. But two in a row only lasting a month each, and it's hard to consider a third, or fourth...
Sorry yours is glitching out on you, hope you get a satisfactory resolution.
I have the same problem. Exactly like you describe above. Since my Pixel C is one month out of warranty there is nothing I can do except warn others not to buy this product,
Oliver Browne.
Same here for me. First one started with screen issues as described above, lucky for me i was 3 days before the end of waranty, second one lasted 93 days... 3 days out of waranty for a replacement device! Thanks Google for a cheap device...

I face the same issue, and was able to turn on the backlight by adjusting its brightness using the touch screen. Try shining a torch onto it while locating the brightness setting. This temporary fix works for me every time, and hope it helps someone.
Trying the torch was very useful! I now know for a 100% that the backlight doesn't work. I used the torch to see what I was actually doing on the screen, and erased all data & cleaned the cache.
Unfortunately the backlight stayed off, so I assume it's a hardware issue.
I've sent an email to Google support, hopefully they can get this one fixed or replaced.
did you manage to fix your issue ?
Same issue here, and no not resolved.
The only thing I can do to work around it is keep tapping the power button every second. Eventually you get lucky and the backlight will turn on. (Rebooting doesn't seem to be needed.)
Hi all,
I bought this tablet as a gift for my little brother. He encountered the very same issue 2 or 3 weeks ago, and it became worse today, as now backlight won't turn on anymore, even after a reboot and a factory reset.
It must be a hardware issue...
I will try to contact their after sales service, as the tablet isn't even 6 months old.
HI, my first Pixel c met this issues after 20 months... first it was only sometimes and backlight came back after some pushes on the power button... but it get worst and worst: 2 days without backlight and at the end half screen fuzzy issues. I order a replacement product with my warranty (2 years in Europe)... and now my second Pixel meets the same issue... with a no responding screen issue too... it's awful and my warranty is over yet... nothing can fix this...! something seems to be bad quality in this device....
I'm on my 2nd pixel c and final. Google support said that because they had replaced it under warranty the warranty only applies to the original purchase date not the replacement which seemed BS to me because I was shipped a refurb tablet
Never the less using adb/ fast boot I was able to get the device into bootloader and blindly reload the entire operating system. It was only until I performed a wipe within TWRP that the screen started working again. Interesting and now off it is working for the past hour or so. Currently applying latest updates but not holding my breath. Unfortunately it looks like Google is killing off the tablets and I don't know if any of their Engineers have actually tried to use a Chromebook in place of a tablet but it just doesn't translate well. If I cannot get this device working reliably I may buy another refurb to get a few more years out of it. The pixelbook is way too heavy for Couchsurfing
The screen comes and goes with no particular interaction. I'm really bummed because I had gotten so used to this device. I buy another but I'm afraid it's going to happen again. I don't see any tablets that are upgrades either. The Android tablet days are over. Pixelbook is not intuitive. Although it runs Android apps it does so very poorly with in Chrome OS and it's very bulky. I'm a try my luck with another refurb off eBay. Have not been able to find anyone that can repair it

Chinese refusbished LG G4 with bootloop problems

A while ago I had the bad idea of buying a refurbished G4 H818p on a chinese store. It was so cheap I couldn't be happier when it arrived and it apparently worked like new.
A month later I had to read a lot about bootloop and how to fix it as the phone suddenly stopped working.
I managed to disassemble the phone and I found that a new dissipator was applied to the main board but the quality was so low the whole repair lasted just one month. I tried to fix it with some new pieces of copper and thermal paste but it didn't work. So I went to the software solution and applied a tot file that made my phone to not use two cores. The phone resurrected but now I have some random green points on the screen after using it for a while (they are not dead pixels, as they change always) and many apps just crash after loading them the first time (they stay there if I load them three or more times). Are these problems related to the excessive temperature in the main board too?
Can I fix them too?
Thank you.
