Bootloop black screen. Can't restore. - G4 Q&A, Help & Troubleshooting

Alright so I have had my LG G4 since last summer. Last night I went to check my phone, and it was turned off. After turning it on it showed the LG G4 logo then went black. Tried charging it but same thing. Can't restore it because it won't stay in Download mode long enough to be reset. I have read that serial numbers that start with 505 to I think 507 or 509 can have faulty mobo's. I was thinking of taking it into Tmobile to get it upgraded or replaced, but there's one catch. My bootloader is unlocked an I don't know if that breaks warranty, when you turn on the device it shows bootloader unlocked. Kinda stuck here. Please give advice thanks :/.

What in case they knew about bootloop problem on the early stage, or they specially injected this problem to explode in two-three years (when the warranty is off). Just to save a lot of money they offered free bootloader unlock with non-removable message on the screen and "your warranty will be void". In my opinion they should fix it for free, just because this situation is a shame. Mine has unlocked bootloader as well, now in service, but still don't know the status. If they will not fix it for free - I will push them to do this

The circumstances are very different for the US than it is for the rest of the world. Your one catch is no catch. It doesn't matter. Just do it.

Alright I am calling the 611 number today. Thanks.

Not sure if the policy is the same worldwide but mine's just been for repair in the UK with an unlocked bootloader and CM13 loaded on it. They fixed it under warranty with no questions asked.
That said it was repaired by the retailer who probably don't care as they just fix it and claim the cash from LG.

Unlocked Bootloader - Uk repair centre wont fix wifi module

I sent my phone back to the LG repair centre to fix the wifi module but they wont because of the unlocked bootloader. In their accompanying letter they said their out of warranty repair centre could fix it. I called them but they said no.
Now I can live without wifi but when I got the phone back I cant even get pass the initial start-up to use the phone as it cant use my data connection as the sim is only showing one bar and no lte/3g signal. They seemed to have broken the sim slot. I have flashed a kdz to see if it would help but no change. I have tried two sims but to no avail.
Anybody any ideas or are their any repair centres that could fix this in the UK?
Thanks
Would I be locked out of the phone at the minute as I didnt remove my Google account before I returned my phone to LG? Clutching at straws here. Very frustrating as I have an expensive paperweight.
Bummer mate. Sorry to hear that.
But if i remember correctly there should be warranty for the hardware compounds. Or everything can be tied to a unlocked bootloader.
"Hey the usb is toast because unlocked BT"... That's bull.
Better try to get some help from a local repair center. It would not be cheap or you get lucky and you get your phone up and running in no time.
Good luck.
Oh WOW! I just flashed the latest MM kdz using LGUP and I immediately got a full LTE signal. I dont know how but its working. Very very happy!

Yeah I read that if its less than 6 months old and if its a hardware fault it should be fixed under warranty. I will try and get it fixed elsewhere. Not contacting LG again. Just so happy I got it working again. Going to buying a Nexus 6P as a Xmas pressie to myself so just going to use this until then. I have had to use a HTC One M7 for the last three weeks while working in London. Broken charging port and battery not lasting a day. My boss wasnt happy as he needs to contact me but my M7 was always off lol.
Have a good weekend m8!

Have a great weekend too mate.
Just my 2 pennys....... don't rush about the 6P.
As a former HTC and recently LG user i want to tell you, to take your time and look around.
I am sure you find something more interesting and better then 6P.

Bootloop issues on 13B....Due to motherboard

As most of you know its an issue with phones with a serial of 505 and H/W Rev 1... Didn't know it would happen on Verizon or not... Well i can confirm it. Was browsing YouTube and it randomly froze. Now all it does it bootloop. Verizon was cool to deal with on the issue and didn't try to claim it wasn't a problem.
Surprised no one has asked or said anything...
That sucks. I got a 507 serial, so I hope I will be spared. But it will be difficult if you paid off the phone and are not associated with Verizon anymore. Then you have to mail the phone to LG, and I heard their repair service is pretty spotty.
Still under manufacturer warranty. I am thinking of buying out the phone and going to Googles project fi. Verizon is getting too expensive and big for their britches....
I have a 505 but I am still on he original firmware. I think it is the 10B. Is it the firmware version that causes the problems? I have delaying the update since I got the phone in November.

100% sure the answer is no - firmware has nothing to do with it. I had a 505 since the day it was released and I was still running 10B too when the dreaded bootloop issue hit my device a couple of weeks ago. I know others who were running upgraded firmware on Verizon and they got the bootloop issue too.
Yup i got the issue of it bootlooping. I got my replacement every time i do alot of thi gs on my first g4 it will freaze and reboot then a bootloop for a bit
Happened to me in Thursday night. Got my replacement today. I was on rooted 13B on 505

I have been kickin around the idea of switching to project FI also because Verizon is so damn expensive. But I still have my unlimited plan with Verizon, also I am concern with poor coverage.
I also just got mine back from warranty repair this weekend,
The coverage is a little less abundant than Verizon. I noticed I've used less data since going to project Fi. I don't feel like I need to get my moneys worth out of my plan every month.
My Verizon LG G4 505x/v1.0 hardware "pre-order" hit the bootloop issue today. It started with a random reboot while I was going to lunch, another reboot a minute later, then 30 seconds of straight vibrating, then... dead. I've gotten it to show a battery symbol when plugging it in since then, and now it does the same bootloop everyone has mentioned. I've started a replacement via Best Buy's Geek Squad, otherwise I have to mail the phone out to LG, wait for them to assess it, then send me one back. It's already 5-7 days because they're backlogged... which makes me wonder if tons of these have started failing or if stock is just low because the V10 came out a while back.
Does anyone know if Best Buy or Verizon can connect (JTAG method?) to the old phone and extract data from internal storage when it's stuck like this?
LG g4 verizon stuck in bootloop. Pretty much the same thing, I was using an app and it froze and now is stuck.
After a few phone calls Verizon is replacing the device. It was painful though. I had to play dumb and act like I was doing everything "tech" support asked me to do. Even though I already tried everything.
Now the question is with my phone being rooted will they still replace it. Ive had to do a warranty replacement a couple years back and didnt have a problem. Ill update everyone.
This happened to mine about a month ago. I don't know what the serial number was on it, but I got it at Launch. My wife's G4 started having this problem on Friday and her serial number starts with 506. VZW is shipping another.

I sent mine back, it was rooted so we'll see if Verizon charges.
Temporary fix that might work for you guys
I decided to see if I can get my data off my phone using any means necessary and I do mean any means necessary. I was able to get my data off my phone by baking the motherboard. I've included a crappy YouTube video that I made in order to show you that it does work. Hope this helps people out that want to get their data off the phone before they throw it away.

Bootlooping not sure if caused by me or the hardware fault?

Model H815, bought the device at launch. From UK.
So a couple weeks ago I was messing around with rooting and all that, managed to flash a bad file and ended up in a boot loop. Fixed it using LG Bridge, flashed all the right files and was running a rooted device fine.
Then maybe a week after that whilst just using the phone normally, it freezes, the speakers make a weird buzzing noise and then the phone turns off. Ever since it has been bootlooping. I tried fixing it using LG Bridge again, using the 'Update Error Recovery' option with the device in download mode, it says it was successful but the device still bootloops.
Not sure what to do? Will LG replace the board if it is a hardware fault even though the bootloader is unlocked? I may have also taken the phone apart with the intention of baking it, but never did. Would they be able to tell that I did that and then not repair it?
How much would a repair cost if for some reason it wasn't covered? What's the best way to get it repaired? I got it on contract from O2.
Also, if anyone knows where I can buy a motherboard that would be great, as I'd rather just repair it at home instead of sending it off to LG not knowing if they are going to charge me or not.
Thanks in advance.
It is caused by hardware fail, not by you.
Some people admitted that LG repaired their phone with unlocked bootloader, no luck for me, trying to argue with them.
They'll give you a number to SBE (Their 3rd party repair service), again few people admitted that they repaired their phones for freaking free. No luck for me as well here. They've said "It's unprofitable for them to repair it". I actually think they are retarded, thats a quote of first 2 sentences from their response to me: "hank you for your email. If your handset is still in warranty we would ask that you contact LG customer services for further advice, as we only carryout non warranty repairs on behalf of LG. If your handset is out of warranty by date unfortunately we may be unable to offer a viable repair solution." - WTF is that?
Lastly there is no official place where you can buy a mobo, asked LG about 2 weeks ago - no response...

[Warranty] Have you ever got LG to repair your phone with an unlocked bootloader?

My phone fell prey to the ILAPO issue where a faulty motherboard causes the phone to bootloop endlessly. I had unlocked my bootloader and was running imperium ROM previously. LG said they'd repair my phone under warranty, but I'm afraid once they get it they'll change their mind once they see that I unlocked my bootloader ("Bootloader Unlocked!" text is still visible while phone bootloops.)
The way I see it, I have two options:
Send it in and pray they only inspect the hardware (they asked me to send it in without a battery, anyways....)
Bake the motherboard in my oven in hopes of destroying any trace of data (but could this temporarily fix my problem by re-seating the connections and cause LG to decide I don't really need a repair?)
What do you think? Have any of you got your phone repaired after unlocking the bootloader?
EDIT: I ended up sending my phone in and it was repaired even though the bootloader was unlocked! Waiting to receive it in the mail
depending on how much warranty time you still have, maybe you could wait a week or 2 and then relock bootloader method will be published, start watching this thread http://forum.xda-developers.com/g4/general/h815-relock-bootloader-t3506634
@OmnipotentPilot : I did and they did.
I had same issue and sent it in and they fixed it and returned it.
I also bought mine 2nd hand so I had no receipt or anything. I went to website and filled out service request, put a date within a year in where it asked purchase date (or something like that), then it says picture of reciept, and didn't provide one. Then i put the IMEI number in and it came back as repair covered...
also for service requested i picked ( i think it was hardware issue or something like that. then "other" so I could type in that it had the "motherboard bootloop issue".
I got a shipping label thru email, sent it in, it was in the facility 12 hrs (they provide a tracking number once recieved), and shipped back out 2day. whole thing took about a week. but I don't think they actually go thru them once it's approved and recieved. Because when you get the shipping label it says what to make sure is in the box when you send it and it specifically says "receipt" but I didn't have one, so it wasn't in there, but everything got done. I think they actually have a bunch of boards and they just put a new one in and flash the IMEI number or something and send it back out. Because my sd card bracket was bent and broken too and that was fixed as well. But I know the glass and frame / bezzel was mine because I had a small scratch that was still there when I got it back.
My Phone had the bootloop issue, It was 10 days out of warranty (just over a year since purchase) and I had unlocked bootloader and Genysis ROM, Sent it in and it looks like they replaced the insides. It's got a new serial number but i still recognised the same little marks on the outside. It came with Lollipop on so had to re unlock bootloader and install genysis again.
Oh and I also dropped the phone in a stream a few months before but got it out within a couple of secs so i don't think it affected it. But they didn't pick up on that either.
Hello,
No problem for me. 10 days and my phone is back with a new motherboard AND new battery (mistake may be for the battery...).
My phone was unlocked with a custom rom.
Have a nice return
Since LG G4 bootloop had gave us trouble last year, now LG realised their mistake.
So LG should repair whether with warranty or not! Root or not , locked or unlocked. They should repair for free
Yep, I bootlooped mine trying to update CM13 when it was in nighly and they replaced it with no problems XD
repaired no problems
i had same issue sent it in with unlocked bootloader and got it back repaired in 9 days
Sorry to bump but I wanted to let everyone know that I ended up sending in my device. I received an email yesterday that repairs are complete and it's on the way back to me! Will edit original post.
No such luck with mine unfortunately, sent it back stating that it was rooted and therefore warranty was invalid.
Depends on the technician I guess. Mine was unlocked, without any OS and it got fixed (over one year to warranty expires). My friend had no luck though. His claim was rejected despite locked bootloader. What is more, the technician claims the phone was water damaged.
In the EU , the SELLER have to change or repair your device for free in warranty time...I live in hungary...my H815 bootlooped...The LG refuse the service...the Official LG repair shop refuse too...Then i research a little....
Read this: https://www.piana.eu/root/
Tomorrow i'll go to the seller (mobile company, Telenor Hungary) and let's the game begin!
Yes. My carrier unlocked/bootloader unlocked/TWRP recoveried H815 that I bought off Swappa was replaced by LG with no issues. They say they replaced my motherboard, but the entire device is new. New EVERYWHERE. I had an H815, now this device has H811 all over it. They couldn't send an H815, so they asked me what I wanted. I opted for the H811 so I can unlock the bootloader (screw AT&T and their restrictions).
New device is already bootloader unlocked, TWRP installed and running stock rooted ROM until the carrier unlock goes through. Then it will be all ResurrectionRemix.

International model Bootlooped/won't turn on, LG USA doesn't take it, what do

Needed a phone to fill the app-gap coming from Windows(don't judge) until contract expires, and bought a H791 5X on ebay last October. (more on that). Works very well for about 8 month, then it started bootlooping. Searched XDA and found thread by xcnathan32, managed to revive it. Yesterday it was updating apps(not OTA security patch), dropped dark, and won't turn on at all. Held power+vol down until fingers turned blue, and maybe 1 in 20 chance it will light up, warns that bootloader is unlocked, then stop responding and drop dark again. Twice I got it to get to recovery screen, but it froze on one occasion, and on the other occasion shows a weird orange line towards bottom of screen, and I wasn't able to flash anything before it froze again.
As I'm fairly certain this is a hardware issue, I tried chatting LG support. Gave them IMEI, and they say this is a international phone, so LG USA won't support it. chatted with Google, really nice service, but when I gave them IMEI they couldn't bring up any warranty option since they don't have my IMEI in inventory...suggested calling LG support. Just called them, and they checked IMEI and said the same thing from chat(they even greeted me by name without me saying a word), but they did tell me my IMEI belongs in JAMAICA. YeahMan. Or...NoMan?
So I'm running out of options - what should I try next? give up? Go the Chinese route for repair?(and 4GB upgrade?) new ones are on ebay for ~230 so repair in US doesn't make much $ sense...
TL;DR: got international 5x, bootlooped, no repair from LG/Google, what do?
