Just bought one of these great devices and naturally proceed to brick it.
I was following the the instructions to downgrade to the original firmware and got to the part of flashing with the lg tool and ignoring the error dialogs. After 30+ minutes nothing seemed to be happening so i unplugged it and now it is stuck in download mode. When i try to use the official lg tool to flash the official software it downloads the official software and crashes when it tries to extract it. Help please?
Holy Crap! I fixed it somehow! Not quite sure what did it though. I Changed the port for the LG ANDROID USB SOMETHING in device manager to port 47 and in Lg Flash tool used "normal flash" instead of CSE FLASH. Flashed with no errors. Damn that was scary....
Hi all, I've had some issues with my G3 and have got to the point where I need the advice of wiser heads to try and fix the problem!
The phone seemingly died during an update a few weeks ago, but I was able to fix it using LG's tool and upgrading to Marshmallow. Then a few days ago with no warning the phone froze, and gets stuck in a bootloop at the LG screen, with the flashing LED. If I try to factory reset, I just end up with the Android Droid with a red triangle and I can't get any further. I've tried numerous guides I've found to try and reinstall the stock firmware, all without success. (I haven't tried accessing bootloader as I have download mode available). LG's own tool gets stuck at 4% when I try to recover, and I've tried the LG Flash Tool but get an error at 6% (LAF_READ_GPT_FAILED) using the 8974 dll. I've also tried the LGUP tool but that gets stuck at 6% (Error can't communicate with phone[Kilo Packet]. The phone was not rooted and is a 16GB UK version (model D855). I just seem to be going in circles now trying to find a solution, I suspect somewhere along the line I'm using the wrong combination of programs/TOT/DLL files so I could really do with someone pointing me in the right direction here!
Hello, I wanted to unroot my phone from SuperSU, using the Fully unroot thingy that it has. After letting it be for awhile i realized it was just only at the bootup screen where the LG logo is and blue light was slowly blinking. Now I've tried LG flash tool to get me back to factory settings and I've tried different .kdz files, none of them seems to work. Furthest I got: I saw the firmware's name on my phone screen for a few seconds and then it dissappeared. Always LG Flash Tool fails after 9% and it says "Upgrade stopped due to an error." I have no idea what to do anymore with my phone. Any help is appreciated! Computer only recognises my phone when it's in firmware update mode.
Use LG UP...

Lg UP didn't work aswell, didn't recognize my phone, I already got it with LG Bridge, thanks!
My LG G3 kinda died in sleep. It powered off during the night and once I woke up, I tried to turn it off but it's now stuck on LG logo screen.
For a month now I've been going through other threads about this, but still can't find solution that works, I'm not sure if I missed anything.
Phone status:
- It won't boot further than LG logo screen
- From recovery mode, there is only 'Factory reset' option, which I've tried several times, but once again it gets stuck on LG logo
- I can go into Download mode but can't get it to work
So far I've tried with TOT files - LGFlashTool (version 1.5 and 1.8)
and KDZ - LGFlashTool 2014
With earlier versions (TOT files) I got message: Model check information FAIL! - Screenshot: i.imgur.com/N6sxbEt.jpg
And with LGFlashTool 2014 (KDZ) I got: Connection with server fail - Screenshot: imgur.com/wD6vWL3.jpg
While I'm not sure I'm using correct TOT files for my device (it's from Switzerland and has 6SW mark so I went with Europien files), I know that KDZ are good (I've used IMEI search option, so that's all good), but that doesn't even matter since it won't even comunicate with the damn server in the first place.
Any suggestions would be highly appreciated, I've lost all hope :/
Thanks,
Matt
hi bro.
try forcing phone to boot in qualcomm 9008.
and unbrick it with board diag.
for booting phone in 9008 mode you should open back of your phone.
google G3 test point)
on xda you can find few thread about unbrick.
if you couldn't repair it send it to LG Services for repair.
Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!

@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Np we can bring you back to life but as already said without cell service. That's the price for the firehose and unlocked feeling you have now.
Did you found and read my thread here?
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
There you will find some more info and also the IRC details how you can find me. I'm online from Monday to Friday mainly.
It's much easier to talk in chat then here. once all the details are known I will provide a full guide.
