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)

Hi all,
having only had my phone for around 2 weeks tonight the inner screen of my phone has decided to crack whilst sat on the side doing nothing (Yes, I know, likely story but in my case it is true). Luckily Orange have been very good and are sending out a replacement handset tomorrow as it is still under warranty.
All good I thought, but I am now worried that I have to also send the handset back. It is currently running Darkys firmware and wondered if this is likely to be an issue. Also, the phone is configured for my work email and would like to remove this info before hand.
Any suggestions on how I quicky (and without a screen) return a phone to stock would be very much appreciated!
Cheers,
Michael
It is currently running Darkys firmware and wondered if this is likely to be an issue
YES its broken the warranty depends upon how close they inspect the phone etc .
Post on a similar topic within the last two months re no screen
Normal method of returning to stock is .

Pull the Battery and reinsert it.
Get into the Download Mode.
Flash it with a Custom Kernel.
Unplug the USB during the Flashing Procedure
You will end up with a bricked phone which will force Orange to reinstall the firmware.
And as JJEgan said, it all depends upon how they inspect the phone. If they agree for a replacement, then its well and good. Orelse, you can try my method
by your post I gather you don't see anything on the screen. If this is true, why worry. Orange techs will not be able to see what firmware you are running if the screen does not work.
They are not going to install a new screen to see what stuff you have on your phone.
I bought my phone off of the online classifieds, so I thought there was no warranty.
I was having a problem with the USB port not working properly as I got some mushroom soup (Don't ask) in the port. I figured since I do not have any warranty I will take the phone apart and see what I can do. I cut the top of the metal shield off with a Dremel tool and cleaned the USB port out really well. It did work after this, but about two weeks later my internal SC card died.
I brought the phone into Samsung service center and to my disbelief, they replaced the phone, no questions asked. I guess they didn't even open the phone.
I wouldn't worry.

Hello folks,
I just noticed that my camera app flash and flashlight app don't work. No matter what options are selected the LED wont come on
Is there anything should look into before I call them and assume its a hardware failure?
Thanks,

If you have the tools and are comfortable with it, remove the back and see if the ribbon cable for the flash is correctly installed. Otherwise, you'll need to do a warranty claim through Motorola. Regular white and black Xs you can get from the carrier, but I'm not a fan of refurbs, so I use the manufacturer's warranty at all times when available.
You could try a factory reset first just to be sure, but it sounds like its a hardware problem.
The flash seems like it is an easy thing to replace, some of the replacement backs available on ebay come with them too, so maybe get a wood or different color back for cheap at the same time if you are gonna do it yourself.
Good luck

I appreciate all the advice guys...I went ahead and called Moto Support, all they could do was have it sent for evaluation and possible repair since its still under warranty. I tried to offer a credit card as collateral for a new device but they wouldn't go for it...
Not really interested in doing it myself since its only 3 months old, never dropped or anything, very frustrating.
Does anyone have experience with Moto's turn around time ? This is my primary phone not sure how i am going to do this

Weird, my Moto X led flash isn't working either. I've had it only a couple weeks, and it worked fine initially, but now it's not. I also haven't dropped it or anything. I wonder if it is a common issue.
Very Weird, maybe some update screwed something up ?
Does anyone know if there is a way of enabling the LED without the use of the typical apps to verify if its working ?

Just as an update, I took my phone inside the dry sauna and the flash worked, perhaps the heat had something to do with it.. Definitely not a software issue now.
As soon as it cooled off the, the flash stopped working again.
I've filed a repair claim, let's see what happens now..

Sent from my XT1053 using xda app-developers app
My Verizon DE XT1060 started having a flash issue about a month ago. First time it looked like it was barely flickering and giving off no real light with a flashlight app, and same for camera flash. It came back on after a few minutes. Second time a couple weeks ago it was off for a couple hours, and I started filling out a repair form online, but as I pressed on it a little bit, it came back on. I got on their customer support chat and told what was going on and the support person told me to factory reset if it happens again to see if its software or hardware. Last night it lost function again and was off all day today. I reset to stock recovery and unrooted and tried to relock (no success) but the LED flash remained useless. I got on tech support chat again and was told they'd replace it under warranty with a "like new" same device. I haven't completely set it up yet, but afterward I squeezed the light firmly with my hand and it came back on. Obviously a loose circuit or something. I don't know if i should get the replacement or keep it.
I eventually had mine taken care of by Motorola support and it took them several tries. My advice is to make it obvious that it is intermittent and to take pictures of its condition before shipping.
If it under warranty they should handle it but be prepared for the process....

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.
Anyone having the issue where half your screen turns to a rainbow colored snow pattern like an old TV? (vertical, right half) It seems to be an overlay and recognizes the touches underneath, but it won't go away. I've seen others with this issue on other forums, but I don't believe I've seen this here yet. Not sure what' going on. I have just filled out a support request with LG. The only fix available right now is to exchange the phone it seems.
Yes this is a common problem and the theory is that there is a batch of phones from when the phone first came out that is bad(and some of those may still be out there too)
http://forum.xda-developers.com/sprint-g4/general/garbled-screen-issues-t3181507
If you have a Sprint repair store near you you can try to attempt to have them replace the phone. It might take some convincing. However, there is a couple problem going that route. 1.) They may try to charge you a deductible (if you even have TEP) DO NOT DO IT... this is a warranty issue and not insurance. 2.) The phone they swap may be part of the bad batch and there is no way to know so this problem may pop up for you in a month or two.
The only good thing about the sprint repair way is you don't lose your phone as it is replaced right away. The better route to take is to claim warranty with LG. They should send you a new phone but it seems they claim to only fix phones and don't replace them. However, people have already gotten replaced phones so they do replace them as well as fix. The only risk with going that route is they just re-flash your phone and send it back and the problem will still be there as the phone needs to be replaced. However, from the couple of people that went this route it seems they are actually replacing so it sounds promising. Biggest problem is you don't have a phone for a week or two.
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

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.
