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.

At the time I did and ended Downgrade process seemed that all ends well but the device was turned off and no longer enciendio not give anything the PC screen or only recognizes the device as QHSUSB_BULK to find and install the drivers recognize the device with the name Qualcomm HS-USB QLoader 9008 (COM13):crying::crying::crying:
Thanks for taking the time to read the post and I hope you are taking the time to read this, and you can help me solve this brick on my lg g4:good:
any solution? :crying:
As far as I know there is no fix if you attempted to downgrade your bootstack...sorry. There is a bold lettered post warning not to attempt a downgrade. Hopefully you can get a replacement through your carrier but they may deny it if they can figure out what you did.
it is not known whether there will be any solution as lg LG G2 or G4?
I sent mine in to LG repair and about a week later got it back fixed and flashed to 81110N under warranty.
Took about 8 days total.

Bingo! there is no such thing as a hard brick if you got the right equipment.
How much did they charge to repair it ?

Under warranty = No Charge
(or at least did in this case)
Just tell tmo to send you a replacement under warranty for $20. They'll pay for shipping both ways.

I had not heard of that service. Nice.
But, I actually wanted my particular phone back. I don't have any of the problems some others have reported with wonky screens, messed up batteries, wifi issues or whatever some folks have experienced and I did not want a refurb nor even take a chance with another new unit. If I experienced any of these issues, I'd have been all over this for the quick turnaround.
Also, I bought mine outright and am a prepaid customer. TMO's official answer to our service requests is: Suck a big pink ****...go to lg

Yeah but don't they check the device and discover you just voided your warranty ?
Even then it isn't the end of the world, these guys have the tools to fix it.

[Q] To be aware before bootloop

Hi everyone. As we know some of our phones died due to bootloop cause of defective motherboard (or something). I have already had rooted and bootloader unlocked H815. Bootloop did not happen to me but i want to know that if it happen, will i loose warranty cause of bootloader unlocked device?
That's correct. No warranty. Even though unlocking has nothing to do with faulty motherboard or faulty ota or whatever broke it. Anyway i'm thinking that its impossible that lg not knowing the certain action thats triggering the bootloop and could release a patch or something to prevent it.
I took mine to the Sprint store when mine went into boot loops and they replaced mine free of charge. They were aware of the motherboard situation, the only downside was I had to wait for them to ship mine in which was only a few days.

They are both correct.
It depends where the device was purchased.
In the US, if purchased from a carrier they will normally replace through insurance or if still in warranty. I assume this may be the same worldwide, if purchased directly from carrier (I'm sure I will be corrected, if this is not so )
If you purchase the device outright (Ex. eBay, swappa online store) you are responsible for the service charge. UNLESS the online store offers some limited warranty.
LG will NOT simply replace/repair without proof of purchase.

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...

BOOTLOOP issue with bootloader unlocked! Will G4 be repaired ?

soo I made some digging through the internet and i found Official LG statement about G4 and it says that :
"LG Electronics has been made aware of a booting issue with the LG G4 smartphone that has now been identified as resulting from a loose contact between components. Customers who are experiencing booting issues with their LG G4s should contact their local carrier from where the G4 was purchased or a nearby LG Service Center (LG Electronics) for repair under full warranty."
I have unlocked bootloader and they sent me back my G4 from service with bill for over 250$...
I focused on that sentence : " Customers who are experiencing booting issues with their LG G4s should contact their local carrier from where the G4 was purchased or a nearby LG Service Center (LG Electronics) for repair under full warranty."
Soo , what do you think about it ?
When I show that sentence to the service , will G4 get repaired ? or it will provide something else ?
(I'm sorry for my English , if it's bad ,because I am from Poland and it's not my native language )
I believe they usually regard unlocking the bootloader as voiding the warranty. Some have gotten theirs fixed while a lot of others haven't.
Depends on where you at, because I believe in Germany your warranty is not void if you unlock bootloader, cause LG HAS to treat Hardware issues differently form Software Issues, so they are not allowed here to take your warranty away from you if you tweak Software Side

Unlocked bootloader with bootloop / motherboard issue
Hello, I've face the same bootloop issue recently, I had unlocked bootloader. I've contected with LG customer support, where I described the whole situation. I've returned the device (as the customer care suggested me by knowing the situation) to a Hungarian - local - LG service. Now regardless what LG's customer care said they don't want to replace my motherboard because of the unlocked bootloader. :crying:
What you suggest me to do? Where can I check that why someone's got repaired while the other's aren't? It depends on where you live, that they fix this problem or not (even with unlocked bootloader)?
ps: I've got a H815, with T-Mobile carrier lock
Thanks forwards!

Bootloop black screen. Can't restore.

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.
