I've had my G4 for over a year now, and it's been great, especially with Android 7.1.1.
Today I was using Messenger to type a message to my wife when it hard locked, and then rebooted. It then got stuck at the LG logo and I had to remove the battery for it turn off.
I put the battery back in, got to the lock screen, but again hard locked and rebooted, and got stuck at the LG logo.
Thinking I had a bad flash, I booted into TWRP and tried to reflash. TWRP locked before the flash began, rebooted, and got stuck at the LG logo.
At this point, I can't even get into TWRP now. It's been degrading very quickly.
Is there anything to do at this point? I heard that LG had a recall about a bootloop defect due to a hardware issue. Would this qualify?
I realize in my tired haze I posted this in the wrong forum. Could an admin move this to the correct place? Thanks!

use LGUP and a KDZ file remeber that upgrading to a certain version theres antirollback wich means once you in a specific version you can not downgrade. i would recommedn to download the latest 20q kdz flash it with LGUP with refurbished option,. if it bootloops then yes you have a bootloop problem take it to t mobile or LG.
looks like all g4 will get bootloop sooner or later, too bad, it is a great phone

new 6xxx phones seems to have very low chance of bootloop. as far as i have read the thread only a few reports

My phone is a couple of weeks out of a year for the manufacturer warranty I'm sure. Will LG take it back if I can prove it's part of the hardware issue others have had?
Looks like it died completely. How would I go about talking to LG so that they can take it back to fix since they won't publicly admit to the defect? Would I need to talk to T-Mobile first?
Edit: oops, missed the "dead" part. Will it not turn on at all? What about holding Vol Up + Power?
Try T-Mobile first, but they will almost certainly refer you to LG anyway. But don't give up hope - my G4 was 3 weeks out of warranty and LG repaired it at no cost. They even paid for shipping.
As raptorddd said, you will want to reflash to stock to ensure it's not a software problem. There are guides here on XDA, but it's way past my bedtime so I'm having trouble remembering which one I used. It shouldn't be too hard to figure out tho'. I can tell you that the KDZ I used was packaged as a .zip named "H811V20q_00_1123.zip" with an SHA1 hash of 6a0a2b87e90aab590f6f83cd8e740f048215713f.
BTW you didn't mention whether you had a backup of your data. That's a whole other problem, and not easily solved. You'll also need a backup phone because this will take a couple weeks.

I don't get anything, even when I take out the battery and plug in the USB cable it doesn't give me the battery with the question mark in it, which you would think I should at least get that.

Do I just need to contact LG support then? Is there any way to mention the hardware issue or do I just describe what happened? Would be great if they accepted it. Do you know if they fix the phone itself or do they just send you a refurbished one?

I had just flashed LineageOS 14.1 when the lockup happened, so I thought it was a bad flash and wiped /system before it started getting worse. I managed to get it to flash though with the freezer method that was talked about, but if I can even get it to boot to do a quick backup it would be a miracle. The only things I'm really losing is my call log and text messages, so not a huge loss thankfully.
In my case, they replaced the main board. (I think they also scratched the screen, but I can't prove it. You may want to apply a screen protector before mailing it.)

Looks like I can get a response from the phone as long as I keep it frozen. Hopefully I can get it going long enough to get my data off once I can get the battery charged back up. I couldn't even get it to charge unless it was cold.
If it works when the phone is cold, then it's definitely the hardware failure reboot issue. It's caused by heat, over time, eventually weakening the solder connections between the CPU/GPU and the motherboard. When it's cold, the solder joints are connected. When it heats up, the CPU/solder/motherboard expand and the connections are broken. If keeping the phone in the refrigerator or freezer is not keeping the phone alive long enough to back up all your data, you can try opening up the phone and inserting something like a piece of cardboard between the CPU and the back of the phone. After closing up the phone, the cardboard will apply pressure to the CPU to keep the solder joints in contact with the motherboard. That, combined with keeping the phone in the freezer, should give you enough time to back up all your data.
This is the same issue that used to happen to PlayStation 3's and Xboxes (ring of death). The heat in those game systems caused the GPU solder joints to fail. I've also had this happen to 2 of my old laptops (Dell and Thinkpad). In my laptops, the heat also caused the video chips to lose their solder connection to the motherboard. Heat kills.
Hopefully, LG will honor this known hardware issue and agree to replace your phone.

I don't know what caused this.
I got my G1 today. It worked for probably 2-3 hours perfectly fine.
I had an app freeze (either Barcode Scanner or Lock 2.0) and had to do a full hard reset.
Now, whenever the phones screen darkens or I put it to sleep manually, it WILL NOT come back up.
I have factory reset three times now to try and get this to work.
When the screen is black, all buttons on the phone still light up and so does the LED indicator up top. I had my phone set to use a locking pattern screen at one point during one reset to test out and when the screen went black, I was still able to try and log in by doing my pattern. It unlocked, but still showed nothing on the screen.
Please help!
I've tried:
Turning Wi-Fi off
Turning 3g Off
Disclaimer: Yes, I've searched. I can find other users with the same problem but none of them seem to have a solution.
Phone is NOT ROOTED and has the factory ROM.
Update 1: Update: It only freezes/blacks out when I try to wake the phone from one of the front key buttons.
If I'm sliding to unlock, it seems to be fine.... (but if I've already tried to open from the front it doesnt)
Update 2: If I mash all the buttons in random orders for about a minute or two it seems to come back. Anyone have any idea?
Update 3: I'm thinking this has to be an issue with none of the buttons waking the phone up when closed. If I lock the phone with the "END" key, and then click the front "END" Key again, nothing happens. If I slide the phone open, and click it twice - the phone wakes up.
Update 4: Confirmed update 3. Phone will not unlock via front keys unless it's slid open (or open enough to trigger).
I would really, really appreciate help with this.
Hate to bump this, but I've added some detail on the top and bottom. Have to leave for work, hopefully someone might have an idea by the time I get back.
Well you can try to reload the factory rom or root it and try a custom rom and see if the problem still exist. If it is still happening then it would be a hardware problem and need to be sent in. And yes you will still be covered under warranty with HTC since the phone is still less than a year old.
I had a problem with exactly the same symptoms. It turned out that the SD card was cocked-up so home, core, and some other process would hang trying to read it and the phone would not wake-up the screen any more.
Did you try removing the SD card and seeing if that helps?

Removed the SD card and rebooted the phone.
No change ( still acts the same way ).
Did you factory reset after or was it an instant change?
I don't mind losing data to fix this.

If you use the official update you don't have to have root. There are some links on here. I'll see if I can find it for you.
https://android.clients.google.com/updates/signed-gfh-CRB43-from-CRB21.c88b03d2.zip
That should be it, but can't confirm since I'm on my work computer.
Some thoughts--may be useful, or not:
Mine was doing that too, but it was caused because I dunked mine underwater during an urban exploring mission. I dried it out, replaced the LCD screen, and everything worked until it would go to sleep. Then I had to do a variety of button mashes and opening the keyboard to get it to come back to life. Sometimes it just wouldn't come back. The problem grew worse over time.
If wiping and reflashing (no need to use a stock ROM) gets you nowhere, then I would suspect a deeper hardware issue. I see you bought it used, can you contact the seller?
If you want to check for water damage, take out the battery and look at the tiny circular sticker in the battery chamber--if it is not white, it has been water damaged. (And the warranty will not be honored.)
Other Lesson: No urban exploring with G1s.
The link didn't work, btw.

Zero water damage.
That's great news zeabrid! In that case, I agree with an earlier poster--you should be covered by warranty. Wipe and flash a good rooted rom, and if that doesn't work, revert to stock and demand a new phone.

Do you have a link to a guide that teaches how to do this (with the stock rom)? I can only see a few that're spread out.
I'm not entirely sure my phone can boot into safe mode/disk mode, so we'll see about that.
Another update: When I boot into safe mode, the same problem exists.
Edit: Just emailed HTC.
This can officially no longer be considered a software issue.
I just rooted and installed a standard ROM. Same issue.
It happens all the way at boot now, just realized this.
HTC emailed me back and told me to call them directly. Will do that tomorrow.
if I find a solution I'll post it immediately.
Alright, my phone is officially ****ed.
Restored back to the original rom.
New problem now: When I close the screen, the backlight goes out and doesn't come back on. (I can still barely see everything, but there's no light).
Calling HTC today.
Edit: Called T-Mo support. They suggested deleting programs to free up space (I only have 2 downloaded and to reset (already done)
=(
Edit2: Called and placed a RMA with HTC after talking to two of their customer support reps. Thankfully, they forwarded me up the support tier after only about a minute with each person when they realized I had already tried all other steps.
The RMA process was surprisingly easy. I have everything set up, and when I get paid (tomorrow) I'm going to ship the phone out. I was given an estimation of 7-10 business days for full repair and return shipping (which sounds great in my opinion - I've never sent anything in for warranty work before).
I'll update you guys once I hear from their repair team on whether or not I'm going to be covered under warranty (I told them that the phone was a gift to me), and if not what the cost is going to be. Like I said earlier in the thread, all water damage indicators are clear and I have unrooted my phone, so I should be covered hopefully.
Thanks to anyone who posted in this thread.

Yea it defitenly sounds like a hardware issue and needs to be fixed. Glad your getting it fixed and you'll be covered no problem.
Do you know if they charge return shipping if it's covered under warranty? I have to pay my own shipping there, and they had me put a credit card down on file in case I either bail when its already there or they need to charge for repair.

To be honest I don't know the answer but would like to say they would pay for it. But they would have to let you know of the charge before they apply a charge to a credit card.
wow its weird cause im just having a similiar issue now.. in landscape mode.. phone and back light work perfectly. but one i close the screen everything goes virtually blank, everything is running perfectly just the screen light wont turn on..
will try some of your previous methods.. hopefully it works on mine..=/
thanks, for the info zeabrid
I bought a thrill off of ebay, that was stated as being bricked and that it wouldn't boot. I've fixed a bricked g2x so I thought I would likely be able to fix it.
Problem is, the seller didn't tell me that all the water damage sensors were activated. The phone's screen will turn on when you plug it in, and show the lg logo then the charging screen, but nothing happens at all when you try pressing the power button. I tried an alternate battery on it just to rule out the battery.
I was going to try stock recovery, but after seeing the water damage sensors being deep red I realized it will possibly do nothing.
I'm familiar with flashing the baseband of thrill so I flashed the baseband to stock thrill p925, and it acted just like a working thrill would, which I thought was hopeful.
Does anyone have any reccomendations to try to see if this phone has any hope? Anything else I should try? Would you reccomend trying to flash back to stock to see if that does anything? Thanks!!
If its water damage try putting it in the freezer without the battery in. For like 15-20 min take out try to boot. If no go Try again for 5-10. Dont listen to over zelous hardware guys i've fixed THREE phones with this method. One was sitting in a friends drawer for a month and presto. Sounds crazy but all else might have failed. Good luck.
Sent from my LG-P925g using XDA App
no luck
no luck with the freezer trick, tried it for 20 minutes, then another 10.
The seller has agreed to accept a return, which I'm going to do.
I couldn't even find any guides to reflash stock firmware without the phone already being rooted. It was so easy when I bought a g2x bricked (stuck on s/w upgrade screen).
Thanks for the tip, I'll keep it in mind if I ever have water damaged phones in the future (actually going to try it on another phone right now, crossing my fingers).
use the kdz method in the developers form

Hi guys.
I'll get to the point and say that I got this phone towards the middle of July to replace my failing Optimus G and it's already having a multitude of issues.
The phone worked great through heavy usage on a week period at the beginning of the month while I was travelling. Two days ago the right side of the screen began to freeze, either showing colored static or what was previously loaded. I note that the screen still works fine even inside of a different app, pressing buttons, etc. but continues to freeze and load what is actually going on a moment later. Happens on both the recovery mode screen as well as the lock screen.
Now, the phone also began to have crashing issues some time last week. I was playing Fallout Shelter when the device suddenly crashed. This hadn't happened with Fallout Shelter or any other (heavier) games at all since getting the phone. I rebooted and later was playing WWE Immortals when the phone crashed when going through the logo and copyright screens. After this crash, however, the phone went from around 50% battery to 0% and needed a charge.
I thought this was a fluke last week until it did it again yesterday... multiple times.
Last night the WWE Immortals crash happened again but the phone remained at 100%, where it was since it had been charging, instead of dropping to 0%. It powered on after popping the battery and pressing the button. Later on in the night, I was checking my email when the phone crashed out of nowhere. I once again popped the battery and it booted. However, this time, it would not load past the Sprint screens after the LG/Powered by Android one. It just hanged on the Sprint logo. It sat there for ten minutes until I took the battery out. I tried again and it wouldn't get past the LG screen.
I attempted Recovery Mode, which works of course, and cleared the cache and rebooted the phone. Once again, it crashed on the LG screen. I gave up for the night and tried again today. Same thing happened a few more times until the phone finally booted. I get in and try uninstalling apps to clear space to bring the phone to 11 of 32 GB free. I go to check what other "misc." data is eating up storage when the phone crashes again and I haven't successfully gotten it to boot again.
Should I attempt a factory reset? The closest Sprint store is miles away (I live in downtown Indianapolis and there isn't one nearby without taking a long walk or bike ride or bounce across bus lines, whatever) and the last time I got help from was just a new phone (replaced a phone because it's screen was broken, yeah, right. I went somewhere else to get a replacement the second time it happened). I feel like this a big hardware issue a reset wouldn't fix but, who knows.
I guess I should also note that, within the past week, my camera apps (be it the stock camera app or Snapchat) crash when using the front camera and it never loads a preview before crashing and the phone has been oddly hot (be it when I was cleaning up apps, idle, or just when attempting to boot) the last day. Also, as I was typing, I've been attempting restarts and cache clears and Recovery Mode, during one of the tries, never even loaded the options and a power button press restarted the device.
...At this point I'm just curious what exactly could mess with a phone this much. I refuse to believe it's any kind of virus since nothing was ever picked up and I know my way around the internet. I like LG phones, I loved my last one (other than it didn't have an SD card slot, but, eh, cloud storage!) and I like the cameras.
Phone is an LS991, unrooted.
From what I have been gathering(and this is all hearsay!) is that the first batch of these phones have serious hardware problems that might be related to the CPU. The best option would to try and get LG to replace the phone as they are less likely to have a phone in stock still that was part of the bad batch. If you can't get them to do it then try a Sprint repair store and see if they will swap it out. Be clear that this a warranty issue and not issuance issue. As a last resort you have to claim insurance on it.

Well, that's somewhat depressing to figure out that they messed up part of the batch but that always happens if it's true.
Guess I'll have to check with LG or get someone to drag me to Sprint to see what they say. I'm not one for getting insurance on tech (and given I got the phone for cheap, being due for the upgrade and all) but hopefully warranty can help me out. Thanks for the heads up!

Spoke with LG last night and the customer service rep was pretty clear that LG does not replace phones they only "fix" them. I would not trust LG to give you a new phone at this point as they will most likely just re-flash the phone and send it back to you. Unless anyone else who has dealt with LG repair in the past can say otherwise I wouldn't go the LG route. Now, if someone bricked their phone that might be a good thing to try since Sprint repair can't flash phones but if you need a new phone it looks like Sprint is the way to go. Just make sure you are clear that this is a warranty issue and not insurance. I bought my phone at Best Buy so this will be interesting for me as they probably will want nothing to do with me since I don't have TEP. I will report back on if they give me the shaft or not because I am sure others might be in the same situation as me.

Late reply is late, whoops.
That's interesting. Never really intended on the LG route since I've never had issues with Sprint replacing a device in the past so I'd go to them before anyone else (which we are, when my mom comes down to help me out with this since the closest store is just too far away and it's her cell plan).
And man, I wouldn't be able to stand buying from BestBuy but that's my personal qualms with them, hah. Hope you had good luck with them.
Hi. We have c got the same phone. Got 4 of them and 3 working great but my husband's is doing the exact same thing as yours and like you we have no insurance and had same reply from lg. And best buy was no help at all. Wondering if you figured out how to fix it or not
Forgot to mention we are verizon not Sprint. Not sure if that matters.
Just got my G4 replaced with a brand new one at Sprint. I have TEP, and they said they'd normally order a refurbished one. But, I got lucky since there are no refurbished ones (they're on backorder, probably due to these issues), so they just gave me a new one.
Lets hope this one one wasn't a lemon like the first one...fingers crossed because I love this phone...
We called verizon and they are over nighting a new phone. Thank you for the reply tho
This happened to me as well. It crashed maybe twice a day and now I can't get it on because it is crashing 1000 times. Its stuck in a crashing loop. Sprint is giving me a completely different g4 when their next batch comes in. It has been 2 weeks and I still don't have a new phone. I am hoping that I don't get this problem again or I am getting an iphone 6.
My phone decided to not switch on any longer. The only sign of life is the notification led blinking red when is in charge, no way to access it with any program if I attach it to the PC with a USB cable.
I should send it to the Sony repairing center (still under warranty) but the phone is rooted; given its situation do they discover it ?
I had that exact problem. Turned out that the battery suddenly died after about a year.
In my experience they never care what stuff is currently on the phone. Instead they'll just flash it with the latest stock rom after fixing the hardware.
Thanks a lot for sharing your experience. I really hope will be the same in my case as well. I'll post here what will happen.
PS I'm wondering about the batteries' quality: my daughter with a z1c had your same problem (a little more than one year life), you, may be myself... I know the sample is not significant but...
Same thing happened with mine & i was on a custom rom with unlocked bootloader...they probably had no way to get into the phone just like i couldn't so they probably couldn't tell it was modified...it was just a brick at that point...i noticed certain batches were affected by this sudden death and after pulling my tag out i noticed my phone was part of that batch that was poorly assembled in china...so brand new phone for me!

I have the impression they dont even check the software, they just flash a new fw and thats it. Or they dont care.

Thanks for the suggestion but I tried any possible way to resurrect my phone, including what you're saying, without any result. I hope to confirm soon what all the contributors to this thread are saying...
Just received the device from assistance; everything went well: the motherboard was replaced.
The only drawback is that the lost the tiny grill that cover the mic at the bottom of the phone !!!!!
I'm not sure what happened, but when I woke up today my G4 was stuck on the LG logo. If I pull the battery and put it back in, it will start booting by then freeze on the yellow Sprint logo, and then start rebooting again. The second time it doesn't leave the screen the LG logo. I've not changed anything on the device (rooted, ZV5). It's been rock stable until this mysterious event.
Any ideas, comments?
I'm going to see about trying to reflash stock (maybe I'll go past ZV5 now).
Oh, crud. This sounds exactly like my problem, and my serial starts with 505.

Yes I also had the same symptoms, but it happened while I was at a Sushi restaurant and my phone was safely in my pocket. It turns out it's the dreaded bad motherboard, and the only solution is to initiate a repair through LG directly (if you prefer to keep your existing phone), or if you have the repair warranty, you can try your carrier but that risks getting a refurb unit that may have other problems.
Some people report temporary success by either freezing the phone, or even baking the phone. But these are temporary only, just to give you enough time to retrieve any important data before the phone resumes the bootloop problem due to bad soldering on the motherboard.

Thanks!
Sprint has in fact ordered me a replacement that I can pick up today. Does LG really just replace the mainboard with a new one, or do they give out refurbs, too? If Sprint only has a refurb for me (which I suspect), I wonder if I should decline that and ship it off to LG instead.
FWIW, I tried freezing the phone, but it had no effect on the problem. I see in the other thread most people had no luck with cold, but lots of luck with baking it. I don't really want to try that, though. My backup is 2 months old so I'll just have to live with kicking myself for not doing my monthly backup on schedule.
In my situation, I got back the same phone from LG with a new motherboard. I had noticeable markings on the outer frame that were right in the same spots on the returned phone, so confirmed it was the same frame. The label under the battery was the same too.
One thing I noticed was a new single piece of dust under the camera screen, so that again confirms they are disassembling. I plan to open my phone to add heatsink pads, and will remove the dust at that time (It doesn't affect the pictures noticeably, and I wouldn't have seen it if I didn't closely examine my phone to see if it was the same phone).
Anyway I personally had a bad experience with an old refurb phone years ago, so I preferred to go through LG service, not Sprint.
What ROM did you phone come back with, and how long ago did you send it in? I'm hoping they are not sending out ZVB (yet), because then I'd be stuck on Marshmallow without root.
I'm about to head out to the Sprint store tonight; if it's a refurb and on ZVB I will definitely not let them replace it, and will instead roll the dice again and RMA it with LG. If it's just a refurb but ZVA or earlier (which allows me to rollback to ZV6 and get root), I'm not yet sure what I'll do.

The replacement I got from sprint is a refurb with ZBA.
Oh, as for what ROM, at the time I think they had just released ZVA. My phone was on the earlier ROM, but they returned the phone with the latest ZVA (at the time), so if I were to guess, I think you will get the latest ROM, which right now is ZVB.

Thankfully I got ZVA, so I'm about to downgrade it to ZV6 (which is safe: http://forum.xda-developers.com/sprint-g4/development/howto-downgrade-to-zv6-upgrade-to-t3265976)
