Recover on from bootloop on H815 EU - G4 Q&A, Help & Troubleshooting

Hi guys,
Yesterday I got sweaty hand palms.
My EU 815 G4 is unlocked, the official way, and I had rooted it.
Then I tried to install xposed from twrp and I did something wrong, and ended up in bootloop...
I have just updated to v20b before, and forgot to connect the phone to the PC, and allow the PC debug access before installing xposed, so i could see the phone in ADB mode, but couldn't access it.
Of course I hadn't made a backup before this - I like to cry
Just as a desperate try, when everything else had failed, i thought about using the new tool provided by shakeyabooti LG UP to flash the factory KDZ all over
I put the phone in SW. update mode by:
1. Turning off the phone
2. connecting USB cable to the PC
3. Press and hold vol. up while connecting the USB cable to the phone
Then i downloaded the v20b KDZ file, provided by Autoprime (since this was what i where allready running)
Opened LG UP, loaded the H81520B_00.kdz, marked REFURBISH
Lastly i pressed "Start" and waited for about 15-20 minutes and "TADAAAA"
The phone where up and running again... only things lost where root and TWRP
- Sharing since I'm properly not the only one ending up in this kind of mess :laugh:

Just tried it no luck :/
So just to confirm...unlocking bootloader official way does void warranty and we can not send it in for repairs?

Indeed. Maybe you'll find a cool employee at your vendor who will still do it, but your warranty is definately void and they don't need to do anything. Depends on how acommodating the employee is. If you're stuck in a bootloop @rakinisbat just follow the steps in this thread.
And please keep in mind that there's a way to get out of bootloops 99% of the time (in fact 100% if it's a software related problem), you just have to do a good search on xda. Furthermore there's an uninstaller app for xposed in the official rovo89 thread, which you can flash via recovery and it which undos the xposed installation and your phone will boot fine (if you can access TWRP - just flash it). If you have further questions you can PM me, always happy to help

Thanks Mate, I guess ill have to try my luck with LG,
I have that batch of H815 with the faulty motherboard, unfortunately I'm in that 1% *Sigh* :crying:
Tried literally everything i could with the software, pretty much confirmed it is the motherboard.
It looks like the KDZ is flashing properly, as LGUP shows whichever kdz i put on, but the actual hardware is not capable of booting into the OS.

Ugh, okay that's bad luck. Sorry to hear. If it's a motherboard problem I can't help you unfortunately Sorry for that. What is exactly happening when you try to flash via LGUP? Just curious

Oh yeah that really sounds like a hardware problem. Damn it LG! But is your bootloader still locked? You might have a chance to get a new one if it is And if it's a hardware prob you still have your warranty, haven't you?

Nope, my bootloader is unlocked, im a flash-a-holic, longest i have lasted without rooting or unlocking a bootloader is about 2 weeks. I would have never imagined such a massive hardware issue with a flagship phone. I'll probably get a nexus 6P atleast it has better support than a LG. I'm in Australia, I imported this phone when it was released, so i have to send this phone overseas if i want it repaired, which they will most likely deny.
Sooooo over LG now! There are like hundreds if not thousands that are effected they are not even acknowledging it or providing a viable solution.

Good luck with that nexus - it's an awesome phone, too. Bye bye

I've got the bootloop issue. Phone was turning on or not, just vibrating etc. I've dissassembled it, assembled again and it started working don't know why...Now I've flashed CM I was on Genisis ROM earlier maybe that was the issue

Hi sir
I decide to buy lg g4.

It doesn't matter what firmware you have got. Bootloop is happening because of hardware failure.

Damn...just made a huge mistake. phone bricked?

My son wanted to root his brand new phone. i have rooted 8 phones from different phones before with success..... but this time i f***d up...
Accedently installed this on his phone.
http://wccftech.com/flash-and-root-nexus-5-on-android-6-0-1-mmb29k/
executed flash-all.bat and it flashed the bootloader.
For the wrong phone...
It should have been this one..
http://wccftech.com/flash-and-root-nexus-5x-android-6-0-1/
Missed the X......
Now the phone will not even boot any more at all....cant enter bootloader.......does not power up at all.!!!
Jesus...what have i done.......
It here any chance at all to fix this somehow?
Hello and thank you for using Q/A,
because you can't enter bootloader, you can't do anything. You can try to send the phone to Google. Say: It didn't boot after OTA Update.
Kind regards

Yeah it's most likely a paperweight. Try sending it to Google. Flashing the wrong firmware destroys a phone as you probably already know
well

I am totally aware of that....
but somehow one must be able to flash the bootloader from scratch....
Normally via special software etc.
That´s what i was hoping for....
Only thing I know to use is a riff box to jtag it. Not sure if they have one for 5x.

Your use of the period seems rather condescending. And no, you as the end user cannot fix that. You did one of the few things that is unrecoverable unless you manage to get the bootloader to accept adb commands somehow.

Well. the bootloader is flashed into the phone from the beginning aswell during manufacturing. I work with electronics and software and i know there is always a way to reflash the bootloader. All the electronics comes in the beginning with no software at all, one only needs the proper software/hardware. Most probably by jtag....or if they have some other special tool for snapdragon 808.
Stupid of me not to see that the version i flashed was not for nexus 5X...and only for nexus 5
sight...
Good luck. Will Google not rma it?

LG G4 qhsusb_bulk After update .

Hello Xda
I tried to update my phone using LG Tool , But while the update process my PC shut down randomly . and my LG won't work anymore at all
but when i connect it to my PC , it recognize the mobile as qhsusb_bulk .
Please Advice ....
Thank you all
Sorry to be the bearer of bad news, as you've guessed it though. Looks like you got a brick in the oven and can't feed your droid any new data now. Unfortunately, I don't know of any sure shot methods that will bring it up to par. I suggest either contacting verizon for a new device or the insurance for a new device. Maybe someone who's working on the bootloader, if there are any can help you but by the sound of it, you need a funeral service for your device. Sorry for the fluxed luck. Who knows though, I am not always 100,000% accurate with devices which aren't in front of me to tinker with. Best of Everything lucky to ya though.

This happened to me too, but i didnt use the LG Flash Tool cause it wasnt working for me so i used LG UP instead. I flashed the right .kdz file for my model and everything but when it finished flashing it remained in a bootloop and now it wont turn on. whenever try to put it in dl mode it doesnt show up with the screens i just see it connected as qhsusb_bulk in the device manager.
i have the open international version so im guessing bootloader so im gonna wait for fix files :fingers-crossed: although its gonna be a while im pretty sure :crying::crying::crying:

What are the files that one would need to fix this? Have they been released now? I've got a phone being recognized as a QHSUSB_BULK as well, and I'm wondering if these files would revive mine as well.
https://forum.xda-developers.com/tmobile-g4/general/lg-g4-h811-complete-unbrick-guide-100-t3461629 do some google searches for lg g4 unbrick tool then read and read and read.

Nexus 5x stuck at google screen [Potentially Hard-bricked]

*** The issue is resolved!!! Thanks to xda, the solution is provided in the link in the comments.***
Couple of days ago I got this OTA notification that Android 7.1 preview is available for update. As my phone is rooted I started the manual update procedure. After the flashing was finished, I restarted the phone and then I saw it was stuck at the Google screen. Just stuck, no response. Seemed unusual to me.
Let me tell you that I have been modding my Nexus 5 for about two years. I am familiar with most of the tweaks that can be done to a Nexus device. Nexus 5 served me amazingly. I bought Nexus 5x 3 months ago.
So, after it was stuck I restarted. Still stuck. I will tell you step by step what I did then:
1. Flashed the OS 7.1 again (I dunno why, the flash.all script doesn't work for me, so I always do that manually) - result is the same.
2. Last October update (NBD90W) was available in the folder so I flashed that - same result.
3. I downloaded the previous one (NRD90S) and flashed that - same result.
4. I locked the phone and unlocked again to erase everything (not sure if that's a good idea), then flashed the OS again - same result.
5. Then I tried LGUP and the tot files to give it the factory version. LGUP detects the phone, started installing. When the installation is finished and the phone restarted - same result.
6. Now that I gave it the factory version the phone got locked!
7. I searched google for hours but couldn't find a way to unlock it as the OS is not booting and I cannot turn USB debugging on!
8. Then I tried the default recovery mode (Android recovery, from the recovery screen Power + volume up) as it doesn't require unlocking the device. Wiped the cache and restarted - same result.
9. My phone is detected by the pc and ADB. So, I wiped everything and tried ADB sideload and get this error E: footer is wrong
10. I tried Nexus root toolkit. It detects the phone in fastboot mode, then restarts it and then it again is stuck on the Google screen.
I am extremely depressed!
I am from Bangladesh and there is no authorized LG servicing center here. So, I can't ask for their help.
All that I did over the past two years was the awesome threads of xdadevelopers. So, a big thumbs up for you guys . :good:
I learnt from the web that phone can be hard bricked if a wrong bootloader is flashed. That's impossible for me as I always remove the factory image extracted files after flashing is done from the ADB>platform-tools folder.
Now, is the phone hard-bricked? If it is, what to do with it? Will replacing the motherboard get my phone back? Any kind of suggestion will be very much appreciated.
Bummer. This sounds a lot like what I just posted here: http://forum.xda-developers.com/nexus-5x/help/req-help-bootloop-7-1-1-beta-ota-enter-t3486957
I really hope someone has an idea how to fix this...

Please say something about replacing the motherboard. It's very very pricey, so I want to be sure -_-
sounds like its hardware problem, contact seller to replace it. if not going to happen, then buy a new phone from a company that does have a dealer in your country to warrant. aside of camera, the specs of other phones at this price range are better
That thought is also roaming around my head, still Nexus is Nexus!
What's the price going for the 5X over there? It's as low as $280 here in the US which is easy better then it's original.

Try the tutorial here. It's little bit different from the original thread ,
as @bardhi92 said, THE MAIN DIFFERENCE HERE IS THAT AFTER I FLASHED THE .TOT FILE, I BOOTED MY PHONE INTO BOOTLOADER AND DID AN ADB SIDELOAD OF THIS OTA.ZIP
Well, for my case, eventually I successfully bring my N5X alive. The tricky part is to enter Android System Recovery (hold Power + Volume Up) after flashing TOT.

A warranty is a warranty, it doesn't matter what country you're in or where the repair place is. People in Canada send stuff to the USA for warranty issues all the time. I'd get on the phone with LG until I heard what I wanted, but I'm a stubborn old goat lol.

[CLOSED][ANY BL locked G4]need testers [follow the new thread!]

First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
Please follow the story here now:
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
Previously this was the OP:
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)
.

Super excited about the possible G4 unlock! Wish I could test it but my phone is my daily driver and my source of internet at home so if it breaks, I'm screwed for my online classes. Thanks for your hard work as always!

It happened to mine 818p too, you need to disasseble it and short two pins on the motherboard while starting it. (They are in the upper left corner on the MB.) This page (forum.gsmhosting.com/vbb/f779/unbrick-lg-g4-brick-hs-usb-qdloader-9008-without-box-2211744/) has the entire process explained but I was unable to sucessfully use the QFIL app, it didnt recover anything, at least the phone was seen on PC as the 9008 serial port. I hope it helps
P.S: Sorry for my bad english.
i hope you get it going man. so lots of users can enjoy this device like it should be.. youll be saving LG G4.. am glad that what i mentioned you got your brain thinking and finding ways i beleive this all was what i mention on fish. good luck to all of you.:fingers-crossed:

Oh, sorry, I thought it was bricked, not physically broken.

Yea i still used it for about 6 months. Put the fish to her. Even still vred with thr cracked screen. Like i said. Went to check the time and nothin. So im assuming shes dead. Ive done got a g5.no root and no twrp. Yea. Just the way i like it. I know i know. If i wanted root i shoulda bought an unlockable model. But i take what i can get cheap. Bought my sprint g5 for 25 bucks at a police auction

Hi, I have the model H815T but... now it Hard Bricked haha. Anyway, I can boot it like LS991 model (with QFIL), and Download Mode it's working too. So... is useful for your method?
steadfasterX said:
First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)

Now out of curiosity would a bootlooped g4 work. Most of em boot into dl mode and if it bricks dl modde youd know rite away anyways right?

Qcom 9008 mode? It could be fixed afaik.. You can also try the sdcard boot method for this kind of brick. you should try that first in any case..
I'm not sure if my method will work in that kind of brick mode you are in but if you nevertheless want to test you need Linux / best is using FWUL because it has everything needed inside.
Once ready went to IRC on Mo-Fr and stay until Im there.

it depends. When it stays in download mode without looping.. yes - maybe!
I need access to to the partitions which may work even in download mode via a special shell but it may requires MM and will not work for LL firmware (strange right? normally one would expect the other way around..).
That has to be tested though. On my device (locked H815) I had access but that may differ from other models.
Having root access makes things so much more easier
Testing if it would be possible on a bootlooping device would be simple:
You best use FWUL (recommended because here is all installed and working) or any other Linux with the LGLaf shell.
You would then connect while in download mode and you will have a shell like in adb.
I can guide you but again IRC is the best way to go here..
I'm searching since several days for such looping and even otherwise broken/defect devices but they all want to have a plenty of money for it (80-150 €!!)

Yes, QCOM 9008 mode. I can't flash the H815 image and make my G4 H815 again so, the only way to booting, it's flashing the LS991 image (and with Fastboot; I flashing every partition one by one).
I have Linux Mint whit adb/fastboot drivers, It's enough?

Hmm I can't help you unbricking. I just know that there are ways to do so. You need the correct drivers etc.. But well if you tried all this already we can try
Any Linux is ok as long as you can handle it
Havin TeamViewer installed may help too...
Well so if you like go to IRC Monday to Friday and we will see

Yes. today I have bad and good news.
First of all I had 1 single tester who was brave enough going the first approach I had. Unfortunately my first idea failed.
JL if you see this come back I said I can unbrick your device!!!
Ok so the good news are: I'm able to give you a near unlocked experience with all the things you love like installing custom kernel, recovery and ROM. Without actually unlocking!!! It's all tested on a h815 device which was never unlocked !
Near unlocked means it will behave like an unlocked device without actually unlocking the bootloader. Or to say it in other words: The boot chain verification is ignored.
The bad news: the process is not cleaned out yet but it requires one thing for sure: it will convert your whole device bootloader stack. The basic idea is to replace the whole bootloader stack with a modified one which allows all the mentioned things.
That way is very risky and I HARD bricked my device over 30 times until getting to the finally working result.
It also means that once your device is converted there is no way back atm. Flashing an original kdz will BRICK your device in 9008 mode! Not that bad because you can recover at any time but that's one thing you have to have in mind. It may never be a h811, h812..... whatever again. Until we find a corresponding and working bootloader replacement which may never happen. So no LG up or LG flash tools anymore! Instead you will have the qfil tool.
Again I know no way back to original state so warranty will be very very likely refused once you do this. Ok there is a way to blank out all partitions just for the case you need to send it really back. This should delete then most traces of this hack but no guarantees.
Besides this I don't know if there are any issues in functionality after doing all this. I havent made any tests for this yet. That includes phone calls, WiFi etc. I just checked booting ROM, booting TWRP, flashing supersu, getting root.
I will upload a video asap to show you the current result.
I need to test things further and of course I need testers with other devices. Again that process is risky and even if it worked for me it may not work for you (very unlikely but who knows). Manually forcing the 9008 is very easy and it may be required to do so. This may requires opening the device (I think it will work even without but I need testers.. ) so if you want to test... See you in the IRC.
If all this is working and verified by others I will provide the whole story ofc!
....can't believe that all these above took me 5 days in full time of work. And for what? I mean I do not need it because I can unlock my device OFFICIALLY..
BUT it was all for educational learning. I learned really a LOT of android and qcom during all these hours ...
Ok but Now I need some couple of hours of sleep
See u on the other site..

so........what now ? i have a F500k device . and i'm willing to test your method . but i'm not sure what you are saying here. ( i didn't understand a single word) . but if it means that i can't flash official KDZ or can't use LGUP....no problem to me.
just share to me how i'll do it and if i hardbrick how i'll restore it. thats all.

Hard Bricked, only white light blinks while connecting to PC

First unlocked bootloader,flashed TWRP, was flashing RR,,,>>Got error
Second Again Flashed Stock ROM, Flashed OTA.zip via adb sideload,phone rebooted>>Phone got dead
Only white light blinks while connecting to PC.
Reached Service centre, they saying warranty voided pay 75% of your phone(INR 16999) to get new motherboard replaced.
Saw many threads from XDA mai forum,tried too, but was unsucessful
Please Help

Where did you go wrong?
Did you flash an older stock ROM than which was installed in your phone before you unlocked BL?
Was the RR file completely downloaded? What error did you get while flashing RR?

Why did you flash ota via adb sideload?
Very bad idea - why? Because I bet that ota wasn't meant for your firmware version
Only ever update your phone through the about phone section on a totally unmodified stock rom with stock recovery
Sorry but you will have to take it to a repair shop to either get it reimaged or get a new board that has the firmware already on it

RIP Moto G5's Bootloader Partition
This happened to me too and the only fix was the Warranty replacing the entire Motherboard.
U can try Qualcomm mode (qfil) or blank flash but motorola doens't have released that files (and never will)

replacing the entire motherboard.
@CypherPotato You seriously achieved that? They didn't check for BL unlock status?
I just bricked mine, still uncertain what happened, left it doing an update (OTA) with a 30-35% battery... dunno if the battery ran out during the update thus bricking it or the update with the unlocked BL did it.
Same situation as described, no response while connected to the PC only a blinking led.
Checking for battery drain issues (also present in the G series) by letting it charge for a while.
But commom, what Moto have in their heads, replacing the whole motherboard seems quite dumb, releasing the files can't be that hard. Loved my old Nexus 5, hardbricked it like 3 times and didn't take 1 hour to find how to undo it.

Yeah... Motorola sucks until don't released Osprey (Moto G 2015) blankflash files, since the bootloader is locked for an only and one shipped ROM you cannot update in stock rom anymore, and I don't known the risks of re-locking the bootloader inside an non-shipped stock rom. The best you can do is create an system-dump backup before flashing new roms.
Unlocking the bootloader probally will break all device warranties, because you don't will able to flash another rom anymore.
The unique and unknown solution is reflashing the entire device's memory, that we will need to use the Qualcomm's blank flash files and Cedric blank flash files to rewrite the entire internal memory.
The flashing LED only indicates the device failed to start, but he still alive.

I found this tutorial in the internet for fixing an Moto G4 Plus hardbrick, maybe it's possible to Moto G5 too.

The link is in Portuguese, but u can normally translate it.
