LG G4 won't turn on

I have a G4 with Verizon and on Sunday I powered it down to swap my battery. I had about 30% left on the battery in the phone and a fully charged spare. I put the second battery in and since then it will not power on. I have tried both batteries and connected it to the power adapter... nothing happens (no lights, sounds, or vibrations). I called Verizon and they are sending me a refurb replacement but I'll need to send this one back once that device is up and running. I want to see if anyone has ideas on how to eliminate my data. I do have a SD card with my pictures so that's fine. I just want to erase everything else.
I have been playing with the phone for the past day and a half and I have gotten it to power on for a brief moment here or there. It is very random and sometimes it will show the LG splash screen and then it goes back out. I also have had it vibrate like it is turning on only not to show anything. A couple of times it has vibrated for over a minute straight before cutting back out. And while it was sitting on my desk it was rebooting itself several times earlier today until giving up. Also, when I plug it into my PC I do hear the Windows sound that you get when connecting a drive. But no drive letters appear. I am hopeful that I can get it to turn on long enough to erase everything. The phone is not rooted and is using the latest Android OS (I believe it was 5.1.1) that Verizon sent out in November.
I did not notice any other issues recently and I have swapped batteries dozens of times and never had this problem. It was powered off properly prior to this all happening. If anyone has any ideas of ways I can try to get it back on that would be great. Thank you!
Edit: Also, pressing the volume down and power together does nothing. Only way I have ever got the phone to respond in the past 24 hours is holding power for 20+ seconds and maybe it will work. But then it turns back off.

same here. dunno what to do since i bought mine used on swappa!

Sound like the hardware problem other users have had, including myself just about 2 weeks ago. If this is the case try putting the phone in the freezer for 10 to 20 minutes (I know it sounds crazy) but it worked for me and some others. I was able to power the phone up long enough to get it into recover (pressing the power button + volume down) long enough for me to wipe my data before sending it back. When I put the phone in the freezer I left the batter in and the back cover on.

The phone is still not quite a year old. Contact LG as they have a 1 year warranty. You are running out of time though. They never asked me for a receipt as they knew within a year if it died the fix was on them.

LG G4 is a very vulnerable phone and LG’s Head of US Marketing has accepted that the LG g 4s manufactured before september 2015 had its own set of problems. Follow this guide https://appuals.com/fix-lg-g4-wont-turn/ in order to resolve your phone issues. If this doesn't help, you can send the phone for repair or replacement.

LGG3 won't turn on or reset!

About a few months ago, my lgg3 started restarting randomly (usually if I dropped it), but I never really paid attention to it. Then bout a week ago, my phone would freeze, then restart but not fully turn on (would turn off after logo appeared) and I would have to remove the battery to get it on and running normally again. Then a couple days ago, it started to not turn on at all and when I looked up what might be the problem, I figured it was probably a battery issue. So I bought a new battery and put it in, and it started to boot up but would still turn off after the logo screen. I have tried to hard reset it twice but when ever I press 'yes' to the reset, it would go to logo then turn off. I'm thinking I just need to get a new phone, as it is nearing 3 years old, but I figured I come here just to see if I can get any solutions.

Test your device with the charger plugged on, if the problem persists, it is not battery problem and maybe your motherboard has some issues.

nexus 5x dead

My mother's nexus 5x has just died.
no fastboot no recovery nothing.
I have tried to charge it, but after more than an hour connected to the charger still nothing.
I checked that this charger works on my nexus 5x so it's not the problem.
I also tried to connect it to a computer, but the computer detected nothing.
the phone had 7.1.2 stock (either april or may security update I don't remember which one).
Anyone has an idea why it happened or how to fix this?
Thanks,
Orma

Wow, my 5X just died this morning. Wonder if it isn't just a coincidence or maybe some update like to the Fi app or something messed it up. So I'll post in case others have also had the same thing happen. The Fi app was last updated May 8, so that's not it. But maybe there was some other app or something updated that caused problems. Some of the core apps were recently updated and my phone tried to update some behind the scenes type app, but it didn't work. So I tried manually and it did work. Maybe I shouldn't have done that. Can't remember which app, but checking on my Google playstore apps, maybe it was Google Connectivity Services.
Mine was fully charged and I was using it while still connected to the charger after waking up in the morning. It just went black suddenly. I tried holding power button to shut it down, but it never made any vibration as if it was force shutting off. Power button and volume down button didn't work to shut down or boot either. The computer recognized it the first time I plugged it in showing Qualcomm HS-USB QDLoader 9008 has completed setup. But after that it would show as device unrecognized.
The only way I got anything to look like it was starting ok was by disconnecting the battery for a while. Then it started booting and then the screen just went black again. I unhooked the battery again for a while, reassembled, and plugged the phone in and the battery charging screen showed up, but then went black again without showing the filling up graphics.
So it seems to momentarily kinda act ok, but then soon goes black. Disconnecting the battery seems to reset it to a state where it can try again.
The battery read as 4.16 volts, so seems to be fully charged as I thought it was. I'm going to try doing the battery disconnect again, but I'm thinking this thing is done.

This may not just be a random thing. Several people on Google forums have the same sounding issue from yesterday or today.

By disconnecting the battery and then reassembling, I was able to get to the recovery menu. I chose Restart Bootloader, and after a few moments, go a screen showing the android character laying on the ground with a triangle with an exclamation point and "No Command" text at the bottom.
Holding power button and volume down got it to go back to the menu.
So I tried Recovery and it showed Google in white letters, then went black. Trying Start does the same thing.

This problem is common in the Nexus 5x, I advice you to check the warranty

if I open the phone to disconnect the battery will it void the warranty?
any one has any idea on why it happened?
my nexus 5x is totally fine
edit: I tried again to turn it on, but this time the notification light turned red, so i tried to connect it to the charger again and it seems to be alive now,
that's really weird but it turned on with 1% meaning that for some reason when I charged it yesterday it wasn't really charging

Sounds like you got lucky.
As far as I could see, there is nothing inside the phone that would indicate that you had opened it up. There's no glue, except under the battery, and maybe under the motherboard. But you don't need to lift those to disconnect the battery connector. However, it does require prying the back off and then unscrewing 10 screws. Then lifting off two pieces with stuff like the fingerprint sensor and speaker attached to them. If you make any dings in the plastic back cover while prying, they could see that. And the screws have lock tite on the threads so take some care to remove. I think I slightly stripped the top of one. So if someone really looked, they could see that. But otherwise, except for leaving fingerprints on parts or debris or whatever in there, I don't think they'd notice. I highly doubt they'd have someone go check for other than obvious signs of prying the back off. I'm 2 months past warranty so it was a non-issue for me.
Following someone's advice on the Google forum, I cooled the phone down in an ice bath (in a bag of course) and was able to get it to boot to recovery and even installed the OTA via adb. It then booted to the point of the 4 colorful circles and died again. After putting it in the freezer, it then returned to acting somewhat normal, as in it showed the battery charging graphic while off. The battery is about 1/2 full. But then I booted and it would get pretty far into the 4 circles spinning, then boot looped. So mine is bootlooping and I'm going to see if I can get Google to step up even though it is 2 months past warranty since I bought it from them. The Google people say to contact them with the bootloop problem. I hope they are quietly replacing them since this this appears to result from the last OS update for many people.
That other person was able to boot it and pull their pictures off it. But looks like mine is down for the count. I luckily had backed up pictures and most of my other stuff recently before I went on a trip. And I uploaded pictures while on the trip and pulled pictures off the phone right after the trip. But I've lost some info that I hadn't copied off the phone.

I'm 2 months out of warranty, so I hope Google does something since I bought it from them and they seem to be providing some relief since this seems to be due to the most recent OS update. Or at least some of the people in their forums seem to imply they'll do something.

Well here you go. Explanation was at XDA all along. There's a class action lawsuit against LG for using solder that didn't withstand the level of heat or heating and cooling cycles. Started with the G4, but in April the 5X and other phones were added to the class action. So I guess I could try touching up solder points and get my phone maybe to start up, or try for warranty repair since they seem to have extended the warranty because of this lawsuit.

One guy at bottom of this thread has screen capture and says his 18 month old 5X shows as covered by warranty in their system.

Same here.
Nexus died after some freezes. After 7-10 failed boots it suddenly booted, just to freeze again after 1 or 2 minutes.
Tried every button combo with and without power plugged, no luck at all, just a dead brick with no signs of life at all.
Device was perfectly working till yesterday. No issues at all
Latest purenexus version. Everything was fine.
Don't get it.
Only thing what came to my mind was that we have been to the beach the day before. Had the phone in the backpack, but it went still really hot since the sun was strong.
But hey. Have been to definitiv hotter places last year in Croatia.
I thought i try the revive Motherboard in oven trick, since this oven thing already worked once for my laptop graphic chip which died also from overheating.
Put the MB in the oven for 12min at 200C.
No luck. Dead brick.
Any ideas?
Thanks for reading!

When my Nexus 5x died, LG replaced the motherboard and then everything was even much better than before.

LG has agreed to extend warranties on a case by case basis after they were sued. One lawsuit was dropped as a result, but the other remains. So they may be more willing than usual to fix it without proof of purchase, but only way to know is to call them.

If you can't get any warranty help, then you can try the heatgun method. This seems to basically melt the solder again so that it'll work. If you're lucky, you get the one or few connections that are messed up.
Using a heatgun, I got mine from completely dead to where it performed normally for 9 hours. I thought I was back in business until it rebooted. Then it lasted a bit before rebooting, and every time would get shorter and shorter before rebooting. Now it is bootlooping at startup, but still alive. So I can adb the OTA back on there, clear cache and factory reset. And it charges. But it just bootloops.

By they way, I tried a hairdryer for 30 seconds and it did boot to where I could unlock it, then it froze. The hairdryer just doesn't get hot enough to melt solder and only just heats things up to where there might be a temporary restoration of whatever connection or solder is broken. So I tried about 2 minutes and I could boot and swipe one screen left before it died. The heatgun took 1 minute 30 seconds to get it to where it would boot and work. I'm not going to go at it again since I have a chance at just getting a warranty swap if they extend it since I'm 2 months past the year coverage.

Nexus 5x Bricked?

I just unlocked my phone and swiped down to check notifications. It immediately froze and the screen stayed on for awhile. Then the screen went black and I can't get the phone to start up. Tried holding power for a real long time and also volume down + power but still can't get it to start up. After messing with it for awhile I got it to briefly show the boot screen once and then once more I had it in the bootloader and I was able to scroll through the boot options but when I tried booting to recovery it died again. Connected to my computer the device manager sometimes shows it as "Qualcomm HS-USB QDLoader 9008". Any ideas if there's anything else I can try, or am I totally screwed?

I'm sorry to hear this, but is the known bootloop problem with hardware. It's caused by loosing solder balls on CPU. The best option tries to RMA, if you have a warranty.

That's what mine did. I was able to put it in the freezer and get a little life out of it, but never booted all the way. I used the hair dryer (following youtube videos on using a heat gun) heating of the CPU and motherboard and got some life out of it, but not a full boot.
So I bought a heat gun and got it to boot and for me to take most of the data off of it. Then it had issues, so I did a longer heating and it booted and acted normally. I thought it was actually fixed. But after 9 hours of acting like is was normal, it rebooted itself. It lasted for a while, then rebooted and lasted less time, and the cycle reduced really quickly to just bootlooping. I gave the heat gun one more try and pressed the CPU down with a wooden spoon to see if that made a difference, but it started the reboot cycle maybe 30 minutes into trying to set it back up. Google replaced mine though it was a few months past the end of the 12 month warranty since I bought it from them.
LG is extending the warranty on the 5X on a case by case basis. So you should give them a try.

Thanks guys. I did get it to boot into the bootloader a couple more times last night, but I wasn't able to get it to do anything meaningful. Whenver I tried booting to system or recovery it just hung up on the Google screen. I have it boxed up now and looks like it's going back to LG again.

UPDATE: Got an update from LG that my phone is undergoing repair. When I started the RMA and gave my IMEI they warned me the phone may not be under warranty. But according to the update they sent me they're indicating that it is covered under warranty - so apparently it's true that they're extending warranties to cover the hardware boot loop issues from faulty solder connections. Hopefully they'll even send my phone back with the SIM tray this time...

[H812] G4 Died Overnight?

My G4 was plugged in overnight to charge, and on the following day, I woke up to notice it was completely dead. Strange I thought because it wouldn't respond to anything (recovery/download mode, normal boot, etc.). I assumed it was just the battery's time to die so I ordered a new one off Amazon (PowerBear). I put it in the phone, and it started turning on. Whew, it's back... Right? Suddenly, the screen shuts off during the LG boot logo (before the animation). WTF? Now I'm back at square one. Phone doesn't respond to anything. A couple battery tricks where I take it out and hold the power button for 30 seconds can sometimes get it to show the empty battery screen when connected to my computer, but even that's very rare. If I try putting the battery in at this part, it shows a battery loading animation and then the phone freezes indefinitely.
I've tried multiple USB cables, computers, and A/C adapters. No matter what, I can't get the phone into recovery or download mode. My computers can detect the correct driver as the phone is dead but it still won't work in LGUP. I've also returned the PowerBear battery, arguably prematurely.
If it's of any relevance, I had my G4 screen replaced by a third-party repair store a month prior to this incident, and I find it hard to believe it's just a coincidence my phone dies not too long after. Based off what I know, this isn't a bootloop issue. My friend who works at another repair shop insists it's the motherboard but can't fix it since they no longer have an LG technician. However, before all this, my Android OS was acting super funky - "Android is upgrading 300 apps..." for 20mins upon each reboot, despite it being the latest software, and my data limits had a glitched out schedule where it thought the phone was in the year 2023 despite date/time being set correctly. I had plans to reset the software but not being able to boot the phone anymore has prevented it, obviously.
According to the serial number, the phone was manufactured in November 2015, which I believe is past the date of when the faulty G4s were distributed. So what gives!?
The freakiest part of this is that my iPhone 7 Plus - which was at 100% battery (unplugged) before I fell asleep, was completely drained when I woke up on the same day. I also have no idea what that's about.
Any and all replies are appreciated. Thanks for reading!

All devices up to March 2016 (so 603) are affected by the ilapo. Your story above sounds exactly like the ilapo. Read my signature for the ilapo fix list which may bring up some hours/days/months life back.

I had something similar happen, except it is a 2016 model, I believe, to sum it up:
The battery seemed to be starting to die, so I bought a battery of eBay, but it also was having pretty bad battery life, so I drained the battery, to calibrate it, but now my G4 (H812) refuses to show any sign of life when I plug it in, or try to turn it on, is it also the Ilapo/Bootloop issue, or something else?
