Does anyone know the cause of the bootloop issue with this device? Mine freezes at the Google screen, doesn't even make it to the G screen. Occasionally returns to the recovery screen with the warning of "User data is corrupt". I've tried OTA's to no avail. Sadly my bootloader is locked as it was a new phone which got in to the jam when I upgraded to Pie. One thing I have tried was putting the device in to the freezer which actually produced some results; it got to the shapes screen before freezing! Only reason I tried this was because if the 5x bootloop issue, that helped to boot it sometimes! I might try sticking the motherboard in to the oven in a bit too..... as a last resort.
One thing I would like to know is if there is anyway around this flashing the .kdz files through lg toolkit? If so, anyone have any lying around? Anyone? Bueller? Bueller?
Anyways, thanks in advance,
Dom
Update:
Heating the logic board didn't work, but it did show how amazingly easy this phone is to fix from a component factor!!

Hello,
Recently my Nexus 7 (2013) battery ran out because I forgot to charge it. Since then, it won't boot back into Android when it's turned on - all I get is the black screen with "Google" written on it. I have searched all over the internet for the past few days, but I'm unable to find a solution. I'm hoping that someone here can help me, because the tablet's warranty has expired and I'm completely out of ideas. Here are the things I've tried or noticed:
I can't boot into Android. The tablet gets stuck on the black screen with "Google" written on it.
I can access the bootloader and interact with the tablet via fastboot.
The bootloader is locked. Trying to unlock it via fastboot oem unlock displays the "Unlock bootloader?" screen on the tablet. After I select "Yes", the command line output on the computer shows the following output, but doesn't get any further:
Code:
...
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
Trying to boot into recovery mode from the bootloader results in the tablet being stuck on that black screen with "Google" written on it.
I have removed the back cover from the tablet and reconnected every exposed connector. I couldn't take the battery out because I don't have the appropriate screwdriver. Doing this changed nothing.
Any help would be sincerely appreciated. At this point I'm worried that it is a hardware issue, but I'd like to exhaust all options before declaring it as such, as it would essentially mean the tablet is going in the garbage bin.
How long did you let it sit at "erasing userdata"?
I don't recall specifically on my N7 but I know when I unlocked the bootloader on my 2013 Moto X it seemed like an eternity, which was mostly because there is no progress indicator, it just said "erasing userdata" and sat there for a while. Probably like 5-10 minutes.

Well that is surely too long. Not sure what else to suggest. Someone else with more experience might able to help.. It sounds like your partitions may have been messed up somehow, which I have seen others post about recently with the updates. I'm not sure what causes this or if there are any fixes, but I know there are threads about people being stuck on the Google screen and having issues after the update to 5.0/.1/.2.

Hi,
i had exactly the same problem. I tried everything to fix it and no luck. I had to resort in sending it to Asus for repair. Unfortunately my warranty has expired. I just got a quote from them saying the motherboard has gone and it will cost me £250 to repair!!!!! I almost fell off my chair. A brand new 32gb tablet will cost be around £180. This is surely a joke? I will be giving them a call tomorrow to complain!
I hope yours is still under warranty because it is most likely your motherboard that has gone. I've read a few others having the same issue and its been the motherboard.

Thank you for your response.
I'm sorry to hear about what happened to you. I've been reading around and guessed it's probably a hardware problem based on other people's similar experiences. Unfortunately my tablet is out of warranty as well, and I'm definitely not going to spend more on the repairs than I would on a brand new tablet. I regret purchasing the tablet in the first place, I really expected it to last longer than a year.
If you can, please let me know what ASUS says about this, if you intend to call them. They don't have a subsidiary in my country, but if you get lucky, I might press my chances as well and perhaps I can get this repaired for a reasonable price.
Mine has lasted 5 years more but my Nexus 7 has ended its days the same way as yours. Stuck at google when switched on, and stuck at bootloader when triying to flash it.
Time to go, it seems.
Well, I'm at wit's end. I'm usually pretty decent at borking and consequently unborking a phone. But I think I'm stumped this time; and am hoping that the community here can help me out. Though, to be fair, I suspect that rolling back to my old phone and eventually buying a new one is my only recourse.
So I imported an H815 Open EU from Handtec UK. No real issues on that front. I eventually unlocked the bootloader, flashed TWRP, and used the KDZ method to (clean) flash my way up to Europe OPEN H81510D initially, and then around two months ago, to Europe OPEN H81510E. I've been running that software without issue since that clean flash. And all this time I've been rooted through the TWRP method.
While this is (was?) my first LG phone, it isn't my first Android experience. So I've been using TiBu to back up my apps nightly, was running Kickoff's lovely hybrid theme, and had a few Xposed modules activated to tweak my experience a bit from stock behavior. I was curious about Marshmallow, but autoprime's warning that it could be non-final test software and the fact that Xposed doesn't work on it kept me from indulging that curiosity.
Everything has been going swimmingly until today. No major issues that I couldn't solve on my own. Certainly nothing that booting into recovery and clearing caches didn't fix. I was out and about engaging in a chat via Hangouts with a friend when my phone suddenly crashed and black-screened. I wasn't plugged into the wall or my PC, and I hadn't performed any kind of major update since the 10E flash a month or two ago. I had not installed any new Xposed modules or any rogue Google Play store apps. I was just using my phone normally and it crashed.
I popped out the battery and played around with it, trying to get it to boot up. I couldn't access recovery or even get beyond the LG logo. It would just hang there and after a few seconds, black-screen. Only popping the battery out and reinserting it would allow me to try again. I eventually left it alone until I got home, at which point I figured I'd try for download mode and reinstall the 10E KDZ via a CSE flash. It's always been a last resort, but a reliable one. I successfully performed the CSE flash of the 10E KDZ.
I thought it did the trick, as I got past the static LG logo for the first time and saw the LG boot animation, but it hung towards the end of the animation and black-screened again. Tried a few more reboots. Recovery mode still not accessible. Download mode was only accessible every third or fourth attempt. Finally got back into download mode and figured I'd try to roll back to 10D (I still had the KDZ I had previously used saved, just in case). Everything seemed to start going fine. Download mode's circle arrow animation on the phone was doing its thing, and then I hear the USB connection drop out. The arrow animation hangs, and the phone black screens. LG Tool 2014 spits out an error I can't read (the software is all question marks for me at this stage). Before it black-screened, it appeared that download mode hadn't progressed beyond 0%.
Now the phone is completely unresponsive. Popping out the battery and reinserting shows no signs of life. No USB sounds from my PC. No static LG logo. No recovery mode or download mode. Not even the lonely flash of an LED.
I've never had a phone hard brick, but I imagine this is what it tastes like.
So I'm probably out of luck, right?
I apologize for the long story. Thanks in advance for sticking around.
Maybe a stupid question but still deserves to be asked, what does pluging the phone in a wall socket gives you?

that is strange to happen randomly. The same thing happened to one of my old devices, a 1st gen moto atrix after I dropped it. I can get it to boot up but eventually it acts like the battery is pulled and just reboots. I'm convinced some wires or chip has been damaged inside even though it was only a 2 foot drop on thick carpet... not a whole lot you can do off warranty. Good luck.
Yeah, I figured the phone was toast. Of course the only time I hard brick a phone, it'd be the one time I import one from another country. Alas.
I think I'll return to my Galaxy S4 for now and pick up a Moto X Pure in a week or two, if no other ideas or opportunities present themselves.
As for having the phone plugged in, I just mentioned it in passing in order to rule out a power surge or short or whatever. Just to be completely clear about what I was doing with my phone.
There are already a few other threads on this man. Try to read first and post. Probably it's a motherboard problem. See the date of manufacturing of your device.
I read completely through the first 5 or 6 threads I saw on bricks and was overwhelmed by Marshmallow woes. Mobo, huh? That's a damn shame. Thank you.
Hi all, ok tonight/this morning at work while on my break i went to do my usual thing of having food and watching a tv show via cartoon hd about 2mins in and my phone switched off.....now i thought it was dead so plugged in the charger but no led light, or screen on to say its charging.....i did a bit of googling and find out about the bootloop thingy buuuuut mines not looping, its swtiching on to the LG logo [i did the bootloader unlocker thingy etc so it says tha in the top corner] then it goes off.......i also get pulsing blue led lights too.....if i press, hold the power button after i get nothing, i have to take the battery out and then its rinse and repeat
Hi,
Same thing happened to me today. I was taking a shot and it switched off and same scenario.It seems that we had encountered an bootloader brick in which our device enters in some special bootloader mode in which when you connect it to the computer in the device manager it shows up as Qhsusb_bulk. I read the whole internet and there is a similar brick with G3 the guys were able to fix it. Even there is a tutorial on how to do this which I think is applicable to our device. I was able to install the required drivers and etc. but there is one big problem - I followed the guide and came into one serious problem - we need a special mbn file so we can recover our device and the sad thing is nobody on the internet doesn't have it still. There are many people like us who got selfbricked G4 and cannot fix it without this file. Please if somebody can help us please share the file so we can fix our devices. THANK YOU !

ive seen lots about the bootloop issue, but the thing is mine isnt doing a loop [i have to take the battery out/ pop it it back in, to switch it on then after 10-20 seconds on the LOGO it turns off

on G2 you get security boot error phone is detected as QHUSb_BULK. on G2 the fix was to enter download mode. in G2 vol up then plug usb.
using TOT method and flash tools . flash stock firmware fixed my soft brick.
not sure about the file you mention, maybe you do need it..

I have the issue. I don't do anything special but my phone reboot and stuck on lg logo. But now my phone doesn't want to boot. Sometimes he detect when I'm trying to charge it but often not. Yesterday I boot on download mode and recovery but today it's impossible... I think I have some hardware issue ? Or software with the bootloader...
I don't know how to fix that without access to download/recovery mode :crying:
Same here. Sometimes it boots into recovery/download but most of the times it doesn't. It's a hardware problem I think as LG officially confirmed that there were problems during the building proccess of the first G4 series. I don't want to sound bad but soon or later all phones built before october last year will get into bootloop. I was hoping it won't happen to me - I'm very light user with only light standart apps with no games and other heavy stuff, so the problem wasn't caused by overheating by heavy multitasking. Anyway it happened and I'm pretty sure it's harware related but if somebody can provide the tot and mbn files I will be more than happy to try the g2/g3 unbrick method. The main problem is that these files are not available for h815. I found on other forum tot files for other variants than h815 So if somebody have the tot filesfor h815 please share so we can try to unbrick our G4. Thanks!
same thing heppened to my g4 this week. i called lg last night and they agreed to repair it. i'd just gave them a call.
I sent mine for repair today. I hope they will agree to repare it even that it's with unlocked bootloader and with rooted custom rom !!! What you think ? Will I have problems with them because of that ?
Happened with my phone as well. It was rooted so i was hella scared if they didn't accept my phone. But soon they told me phone's motherboard has gone bad and will be replaced. Got my phone with a brand new motherboard after a couple of hours.
P.s. all your data will be gone

So the same problem just happened to my lg H815 with unlocked bootloader, am really f***ed without my phone, gonna call LG UK tomorrow, anything in particular I should say? also looking for solutions I saw many people are starting to have this issue now too - any official comments from LG?
P.S. if you have an LG G4 you should start backing up all your data now
This literally just happened in the last 15 minutes to me as well. Random reboot right after I woke up the phone and now stuck on the LG splash screen. Light user here, never did anything with the phone that would have heavily stressed it physically or computing-wise, so I also concur it's an inevitability for earlier runs of G4 phones.
Luckily, I backed up everything through TWRP last Thursday by chance because I was updating Xposed to the latest version and swapping to a faster 128GB microSDXC. At worst, I might have lost a handful of unimportant text messages.
Not worth the time to try to figure out any cheap fixes myself, I just got done submitting a repair request to LG.
I ordered LG G4 H815 and I hope to not see any kind of these issues

Hello guys,
I'm new here, nice to meet you!
For about 3 months i'm trying to fix my LG G3 D855 but with no success.
It started with a loud buzzing, screen freeze and the only way to power it off was to take off the battery. Since then it keeps freezing and i can't use the phone.
I tried the trick with a card placed under the chip, it worked, no restarts or freezes for about 3 weeks but after that i can't make it work. I also successfully flashed the D85530B_00_1217.kdz with the LgFlashTool but the problem it's still there. My phone has the stock rom and it's unrooted.
During this time i got a lot of blue/green/black/red/orange screens with QPST Configuration but i can't attached them because i'm new.
Do you have any idea what can i do to fix it or what caused the problem?
Thank you!
I have the same problem and I thought it's because phone gets hot but even when I was inside Cpu-Z it happened and it restart by itself then it stuck on LG Logo with some strange noise, I have to pull the battery out. Sometimes It turns on and works for a few hours .
I haven't been able to find the problem.
If you fixed your problem I appreciate write it here, how you fixed it.
There are no solutions other than the ones listed in the countless threads around the forum (there really is no need to create a new one every time).
You should use a thermal pad instead to help with the heat dissipation.
If that doesn't help only a proper repair technician with the correct equipment (very hard to find) can fix it.
You can as a last resort, try heating the entire motherboard. This is further damaging the phone though, so use it only as a last resort to get the data off the phone.
My LG G3 D855 was working fine... i left it for a while and when i came back to it it wouldn't turn on. I tried to take out the battery and put it back in ad it seemed to have worked but i got instantly a blue screen before the LG boot up animation or the LED color switching. I tried reinstalling stock firmware but i can't get it recognized by my PC. I have heard about baking the motherboard but i want to leave it as my last option since it may lead to permanent damage, my phone was a bit hot on touch when i grabbed it so i think some welds are damaged or something that has been caused due to heat. If anyone can help me i would be grateful because i can't afford another cell phone at the moment and i need one on daily basis.
Anyway thank you in advance for even trying to help me with my situation and i hope you are the person with the right answer
Kind regards,
Harisprodude
