LG G4 Bootloop Issue - G4 Q&A, Help & Troubleshooting

Hey all
I bought this LG G4 from gumtree. The guy who I bought it off said there's a rebooting issue & it comes with warranty. It boots up, you can use it for a few mins then reboot & sometimes may not even reach the boot screen and stick in a perpetual loop where as other times I can get into the home screen & use it for roughly 5 mins before rebooting once again. I've checked out sites saying that LG has admitted this is a hardware fault & should be taken to your local LG store for warranty replacement. However I went to an LG store but they wouldn't repair it under warranty because the phone is an overseas taiwan LG G4, not an Australian model hence they quoted $300 to repair it. The only way is contacting the company which it was purchased from which is eglobal digital cameras & they should be able to repair it through their warrenty but their so slow to respond. I'm thinking would flashing another stock rom fix this issue since the software is corrupt or is it absolutely a hardware fault?

Unfortunately it's the wellknown bootloop issue you have, mine was the same i could use it when phone was cold during few seconds than bootloop...
Try to find a motherboard and change it by yourself as you warranty won't work in your country..

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...

This is a common problem on our G4s, mine is currently on repair due to this problem... LG admitted that the bootloop problem is due to a hardware issue and it will be fixed under full warranty.
I recommand you contact a local carrier from which you bought the G4 or local LG service and tell them about your problem.
They have to repair it for you since they officially admitted the hardware problem.

It's a manufacturing issue. The problem was made while they were producing the LG, so whether you unlock the bootloader or not, the bootloop would still appear.
They basically sold you a device with defect and they are literally BOUND to repair it. When I first spoke to LG here they were also rejecting me but then when I spoke to the main director of something here in my country, a representative here IDK, whatever... and he said you know what, you're right, send your phone here we will repair it.
The unlocked bootloader DOES NOT affect hardware, they can't deny that statement!

Thanks for your help
I am curious to see how this plays out. I'm in the same situation and my warranty is almost expired.

I was worried too, but i didn't want to admit it is my fault, because it's not! It's their fault and they must repair it.

[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....

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.

LG UK denied Guarantee because of Unlocked Bootloader

I had my G4 repaired last year when it suffered the Bootloop issue, It had a custom rom and unlocked bootloader back then but they still fixed it (assuming they couldn't even get it to boot fully)
Long story short, My G4's charging port began to be very temperamental, and I was getting rare bootloops so I sent it back again seeing as it was under Guarantee. After my phone sitting at the center for 2+ weeks without any updates I emailed LG to be told that because of the unlocked bootloader it was out of guarantee.
Has anyone tried to push on with LG and get it fixed after they deny the repair?
If they received your phone and IMEI was confirmed to be unlocked, then you're either getting the spare parts yourself or looking for a new one.
They actually have to repair it.
Maybe it will help if you put preassure on them.
That's not cool, how the hell unlocking bootloader could damage USB port.
Don't know the laws in UK. But lg Sweden have always repared my devices always unlocked.
One time thay couldn't repair it and sent me a store credit for a brand new device 480 usd even more then I payed for it?
Unless they can prove that unlocking bootloader caused the faulty USB (which they obviously can't) then you are entitled to it. Pressure them.
If not, get it back, relock bootloader and send back again.

Is repaired 5x "immune" to bootloop?

I have a 5x. I live in Canada and purchased the phone from google canada. The phone went in to boot loop, then went dead completely. It was outside the original warranty, but within the extended warranty. At first, LG was pushing back, saying the phone is USA only, even though it was sold by google in Canada. Provided a USA return address to get around that. Received the phone back, with invoice saying "replaced board". Does anyone know if the boards they are using actually fix the root cause of the boot loops or can I expect this to happen again?
Yes, phone may bootloop again, without any reasons. There's no hardwere revision which fix this problem.
