HELP HARD BRICKED my LG G4
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.

Well.... then send it to LG.. They don't send refurb units unless they absolutely cannot repair yours.

Yeah, long since have gotten back repaired.

Last time I shipped them my G2 for the digitizer, it only took them three days.

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.

[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.

I returned a PREVIOUSLY rooted LG G4, has AT&T found out?

Hello there, I had previously rooted my LG G4 and then flashed the stock PR rom for the H810, and then when the AT&T American rom was released I flashed that, then I updated to Marshmallow and eventually my phone fell into the equivalent of a boot loop, the phone would VERY frequently go completely blank with this weird rainbow static, to the point where I couldn't turn it on past the AT&T logo, ther was no water damage and I never dropped it. I tried flashing the stock rom again and it didn't work. So I sent it back to AT&T and they gave me a replacement, it made it to the warranty department and I haven't heard anything since. That is, until a few days ago, I got a call from "ATT Service DPT" when I wasn't home, and I got another today when I wasn't home, they haven't left a voicemail and I don't think I've gotten an email. Is it possible they could have found out that my phone was previously rooted? They haven't cancelled my service or billed me, yet.

Why would they bill you or cancel your service.
Do you have a replacement g4 to keep.

I'm not sure what the point of speculating here is other than driving yourself to worry more. For all you know, it could be a courtesy robo-dial. If it's important, you'll be notified about it one way or another.

I really hope you're right, I'm just some stupid kid (sort of) and I guess I'm probably worrying more than I should
