Hi,
I have a lg G5 H850 stuck into "fastboot for bootloader unlock" mode and recovery or download mode are not working, I tried to recover it by unlocking the bootloader but the OEM unlock option is disabled so I cannot flash anything.(device locked error error message)
I saw a YouTube video yout ube.com/watch?v=ImJ1xXXzV6s with my exact issue but he is not responding to my messages.
Is there any option to unbrick this device?
Thanks a lot in advance to all!

Hi guys,
it's been more than two hours that I seek the solution to this same problem with next to me the LG G5 bootllop.
All other solutions give nothing:
- unlook via fastboot makes a mistake because the debugging option is not enabled
- the download mode does not remain more than 15 seconds
Guys, have you found a way out of this problem?

You can try getting the .kdz for your phone (e.g. off lg-firmwares.com), use the WindowsLGFirmwareExtract tool to extract the .dz out of the .kdz, then use the tool to extract the laf_6.bin out of the .dz. You can then flash this in fastboot mode using a command like
Code:
fastboot flash laf laf_6.bin
Make sure to use the same .kdz as your running firmware.
I had the same problem with Download Mode as you (restarted after 15 seconds). I extracted laf_6.bin from the H85030e KDZ firmware (whose boot stack was in use), and flashed its LAF (i.e. Download Mode) volume over the laf partition. After this Download Mode stopped restarting after 15 seconds, and I was able to use LGUP (and you would be able to use UPPERCUT) to flash the full KDZ.
(I proceeded to start the phone in bootloader/fastboot mode and flash TWRP recovery as well, with my unlocked bootloader.)

interesting. I am in Bootloop from two weeks. Tried to much time lineage 17.1 and then leave the phone so many hours in order to boot in lineage that at some point it won't enter system anymore.
So I passed to LGUP that works only with UPPERCUT and only with UPGRADE functions even if I installed all the drivers.
Maybe I need a "megalock.dll" file?
But the way one week trying to boot in system after flashing KDZ files with UPPERCUT and after many and many bootloop I finally enter the system with H85020a_00_OPEN_EU_OP_1030.kdz
But after one reboot it returns the problem.
I am desperate.
Have you got a phone name to buy that is unbrickable?

I try to root my phone, it was frozen on 3% and i unplug the usb cable.
Now, when i try to turn it on i had this message:" error boot certification verify" then goes to black screen.
I can´t enter in download mode or recovery mode.
What can i do to fix it?
Everything is frozen?

I flash a .kdz file with lg flash tool. I was trying to update to lollipop. But the installation stop and then i remove the usb cable.

did i loose the warranty by canceled the instalation of lollipop?
It was the official version of lollipop.
Yes,you've lost warranty.
Every bloody page on the net says,that root and custom roms cancel your warranty.
Better have thought before messing up.
I'm a phone tech,but before I was qualified for that,I used to read many pages over XDA and the Israeli site for Android phones.
There's a saying here,you better shave on some else's beard.
So,no offence,but now you're shaved,but butt naked.......
Try the help of the guys here.
Just for your knowledge:
You DO NOT study how to root and jailbreak phones on your phone tech studies,because on 90% of the cases,you do not need to do so.
We are past the days of Cydia,black market and custom features that require root.
I basically raped my Galaxy S2 with root and rom changes,never bricked it,but got normal results only when working with the official Stock Rom.
On my G2 mini,I don't even bother to root,and have flashed a stock rom manually through LG Flash Tool 2014.
Even if the flash went wrong,I could have tried flashing another rom,or send it for maintenance,because it was an official flash,and could have claimed it happened with PC Suite,which happnes to do so on many occasions .
I think I've made my point.
Happy post digging,my frined.
Peace!
I am in a massive pickle here.
I installed root on my phone but stupidly enough I forgot to FRP unlock my phone. with also phone unlocked
Phone unlocked
FRP lock
My phone now only boots into erecovery and twrp doesn't load on my phone anymore and have tried multiple times to load it up again.
I have factory reset my phone and tried multiple stock roms to install but all get stuck at 5% and fail.
My build number is ANE-LX1 8.0.0.103(C782)
I then went to DC unlocker to remove FRP and came up with their own error code 'unknown error 405'
I am now stuck on what to do as fastboot device works but when i try to flash something all i get is command failed.
First : have you download your build "FULL-Update" ?
then you need bootloader=unlockt (Phone unlocked) AND FRP=unlock
if nothing help - dc-unlocker can bootloader unlock (4€) and can FRP unlock (15€)
with HuaweiExtractor extract 3 img - ramdisk.img, recovery_ramdis.img, system.img
the Extractor do automatic 3 *.img.header
this 6 files copy to your ADB-folder, then
- fastboot flash ramdisk ramdisk.img
- fastboot flash recovery_ramdisk recovery_ramdis.img
- fastboot flash system system.img
this work only if "bootloader unlockt" AND "FRP unlock" !!!
if flash work and phone reboot - phone boot to stock-recovery and format low-level "data"
if "... stuck at 5% and fail" : your stock-recovery is bad !
if all work, phone boot: all your data is lost (format low-level "data")
factory reset (with format low-level "data") ONLY work with stock-recovery - NO with TWRP
Example
i have TWRP installed
OTA-Update incommig, this write "undate install now ?", i do "NO - later"
i flash stock-recovery
now install the update
if all work i can new-flash TWRP
and 1 question : what the way you root your phone ?
Same sh-t. But in stupid action i've locked boot also. So i have: locked boot, locked frp, no system files, not working recovery (erecovery did nothing helpful (no online updates, no factory reset)) I have nand backup (but dont have twrp) and i have a wish to drop that all-way-stupid-ideas device from ten floor :c Any ways without pay 15e? Better i will smash it and buy something better for smaller cost
I´m in the same situation, but my frp is not locked. What I do is try to unroot my device flashing magiskuninstaller.zip and unSU.zip and everything seems to be ok but on reboot my phone enter erecovery and do anything, the same thing, dont download latest version and manually update with Update.app and dload stuck at 5%. I tried this:
with HuaweiExtractor extract 3 img - ramdisk.img, recovery_ramdis.img, system.img
the Extractor do automatic 3 *.img.header
this 6 files copy to your ADB-folder, then
- fastboot flash ramdisk ramdisk.img
- fastboot flash recovery_ramdisk recovery_ramdis.img
- fastboot flash system system.img
but on first boot there is a bootloop and the second boot sends to erecovery again
My phone is ANE-LX3 latinoamerica, any help will be appreciated....sorry my bad english
please try this :
- download full update rom for your device, extract the .APP files using HuaweiUpdateExtractor
- boot into fastboot by press and hold Volume Down and plug in usb cable into your pc and your phone, hold it until it boot into fastboot
- do this :
fastboot flash kernel kernel.img
fastboot flash ramdisk ramdisk.img
fastboot flash recovery_ramdisk recovery_ramdis.img
fastboot flash recovery_vbmeta recovery_vbmeta.img
fastboot flash recovery_vendor recovery_vendor.img
fastboot flash system system.img
fastboot flash vbmeta vbmeta.img
fastboot flash vendor vendor.img
- reboot your device and hold Volume Up and Volume Down to get it boot into eRecovery and do Wipe Cache Partitions and then do Factory Data Reset, and reboot again
- let it boot normally, and see what happen next, i can't remember for sure because it's been so long i unbricked my Nova 2s with this method. there are 2 possibility, you'll boot into system normally, or it will boot into eRecovery again and there is an option Download Latest Version And Recovery and you can choose that, of course you should have connection to internet via wifi.
please report back if you have difficulties.

Could this method also work for me? I bought a P20 Pro while in China. Being in Europe I did not receive the OTA to Android Pie and I had still Chinese characters popping up left and right.
So I got an bootloader unlock code.
Then used Funkyhuawei to rebrand the phone. The instructions mentioned I had to do the eRecovery twice. But after the first download it got stuck in a bootloop. I cannot get back into eRecovery.
I did manage to clean the data and do a factory reset, but I did not get back in the the eRecovery mode. Now I am stuck.
Thanks

Hi,
I tried to upgrade my LG V30+ US998 to android Pie via TWRP but after the upgrade and system reboot the device got stuck in LG logo.
The download mode isn't working (device not being detected).
LGUP shows the device as "unknown" and adb is not detecting the device either.
I can't boot into TWRP anymore and flashing via LG flash tool 2014 fails (asks for server connection!).
I installed all the tools and LG mobile drivers on another computer and had no luck!
Do I have any chance of recovering my phone?

Why can't you boot to TWRP?
Use the hardware button dance, if you must.

Are you using the latest Dev Patched LGUP from the Pie KDZ threads? Uninstall any prior version and read the instructions carefully.

Your phone is not bricked. No one ever bricked their phone trying to update to Pie. Being stuck on logo is not bricked.
Tons of people get stuck on logo. So what? Then they re-flash 20h or whatever.

Reinstall LG Mobile drivers again.
Uninstall Dev Patched LGUP completely. Delete the folder from Programs/LG Electronics to make sure.
Re-install the Pie Dev Patched LGUP. Use the SetDev.bat in right click Administrator mode.
Then REBOOT the PC. You've installed two major PC components and Windows needs to process that.
Go into Download mode MANUALLY before opening LGUP. ONLY open LGUP from the desktop shortcut, not the folder icon.

I tried every possible combination of the available apps.
Phone in download mode not recognized by the computer (tried on two computers).
If I connect the phone into the computer and open the LGUP it shows as "Unknown"
For some reason TWRP got wiped out after flashing Pie rom and I cannot boot into twrp to flash the old Ore rom.
I finally managed to fix my phone.
Below are the steps:
1- boot the phone im fastboot (connect to tbe computer via USB cable and press and hold both power and volume down until phone reboots then quickly release the power button and hold the volume down until the fastboot menu appears)
2- copy the twrp image into adb folder and rename to twrp.img
3- download and copy a working rom (in zip format) and paste into micro sd card and insert into phone
4- open the command prompt as administrator and navigate to adb folder then type the following commands in sequence
Adb devices
fastboot devices
fastboot flash recovery twrp.img
fastboot boot twrp.img
Now your phone will boot into twrp and you can install the Oreo zip rom into phone and enjoy using your LG phone again!
Thank you!
I've added this to the US998 Pie KDZ thread. That KDZ is very wonky. It's the only Pie people have problems flashing. Probably because LG has not yet released Open Market US998 and the one we are using is technically for U.S. Cellular US998.
I had no trouble flashing it myself -- on my backup V30+(former LS998) going straight from Nougat (never updated, it was my backup phone) to Pie through Dev Patched LGUP Refurbish mode. But lots of other people seem to have problems.
On my daily phone, I'm still on rooted stock Oreo with Magisk and Xposed mods.

I think part of my problem was the Pie ROM.
I have the US998 UCL version and I've read that the LG only released the Pie update for LG V30 US998 model with the Buyer suffix (1CL, UCL, UCK) and US998Z (UCL) only. But I could be wrong!

Right. LG has not yet released the Open Market USS98 KDZ yet. Theory is LG is waiting for the Sprint Pie KDZ to be accepted by Sprint. Open Market USS98 is the official North American carrier unlocked variant that needs to work with all carriers. So, Open Market US998 Pie KDZ (if ever released) will incorporate testing results from the long-delayed Sprint LS998 Pie KDZ (whenever it's finally released).

Hello everyone..
I just got hands on LG V30+ carrier device from ntt docomo model number to be exact L-01K It's network unlocked and using adb debloat i have managed to get rid of almost docomo japan apps.
But i am stuck on android 9 pie. I tried to unlock bootloader official way but my device doesn't go for fastboot. I was wondering someone had this device and whether if it's possible to unlock and flash custom recovery..thank you
before you flash anything to your L-01k you need to backup the modem partitions with LG UP.

before you flash anything to your L-01k you need to backup the modem partitions with LG UP.

If you have no backup of the modem, you will lose network and there's no firmware for the L-01k anywhere on the net to restore... ask me how I know..

Here is elf file if you dont have. You can go to qualcomm mode by plugging in usb cable in mobile and press volume - and power button and when black screen show keep pressing volume +. you also need to install qualcomm drivers to detect mobile in windows.
Thanks a lot for the files and advice! Will try to restore the modem now..
dont restore ftm i mentioned it by mistake.
I can't figure out how to flash the files back using QFIL. I was in download mode volup then connect USB, same as you do it with LGUP). But that didn't work. QFIL says "Download Failed switch to Emergency Download Mode".
I also tried flashing the modem.bin with TWRP (backup in TWRP, then replace modem.emmc.win with modem.bin and rename that accordingly, then restore backup in TWRP. But that did not work (SIM Card not recognized and no IMEI). Then I flashed back the original modem.emmc.win backup to fix sim card and IMEI.
I think I am missing the XML file for QFIL?
first install qualcomm drivers.
plug usb cable to pc and mobile. hold volume down and power button at same time and when black screen show on mobile keep pressing (don't hold) volume up without leaving other buttons.
when qualcomm mode is detected > run qfil and select port and than > select flat build and > elf file in programmer path and > select ufs storage type in bottom right.
then go to tools > partition manager and there you can find all the partitions first backup and than restore which i said before.
these backups will not work in twrp i think.
don't mix this with download mode in which we can go with just volume up and put cable in pc. if you don't know please google it first its qualcomm mode.
if you have fastboot try this command in fastboot:
fastboot reboot edl
if that works than just follow other steps. to quit this mode press volume down and power button for few seconds. in this mode screen just stay black and nothing will display on your screen.
OK found a youtube video on how to get into EDL 9008 mode:
- Connect the smartphone via USB to the computer.
- On the switched-on smartphone, hold VOL- and POWER
- As soon as the screen turns off, keep holding the VOL- and POWER buttons and simultaneously press VOL + quickly.
- The smartphone will have a black screen, and in the device manager on the PC will be "QUSB_BULK_CID: xxxx_SN: xxxxxxxx" or "Qualcomm HS-USB QDLoader 9008 (COM x)
OK, that worked for me (windows device manager reported "Qualcomm HS-USB QDLoader 9008) , but when I wanted to use the partition manager in QFIL i get the "Download Fail Sahara QSaharaServer Fail: Process Fail "
I'll try this now:
-downgrade to Nougat H930 KDZ ( H93010v_00_OPEN_EU_OP_1120.kdz)
in fastboot: (Using the modem.bin, modemst1.bin, modemst2.bin from L-01k QFIL dump)
fastboot erase modem (enter)
fastboot erase modemst1 (enter)
fastboot erase modemst2 (enter)
fastboot oem lock (enter)
fastboot flash modem modem.bin (enter)
fastboot flash modem modemst1.bin (enter)
fastboot flash modem modemst2.bin (enter)
EDIT: it didn't work
But at least I know now how to get into Download Mode from a Bootloop:
1. Connect USB to PC
2. press Vol+, Vol-, Power until the phone restarts with black screen
3. immediately release Vol- and Power and keep pressing Vol+
.. voila.. Download mode
did you add the v30 file in proggamer path in qfil which i provided and changed the storage type to ufs?
yes, I used that firehose V30 file and I verified that storage is set to UFS.
have you fixed it?
nope, but after flashing the modem with ADB and also trying the V300k Korean ROM, I have learned how to fix a near bricked V30 by using 9008 Qualcomm unbrick mode back to life .
I think the only way to fix this is if a L-01k KDZ is released or someone manages to root his L-01k without overwriting the modem and uploads his complete TWRP backup.
Thanks guys for ur help. It seems like no bootloader unlock for my LG L-01K. So modem backup didn't work. I'm so sorry to hear that. I wish i had rooted my device. But i can't even unlock the bootloader. I want to try custom roms so badly. I guess i have to stuck with android pie. Thanks again.

do you have wifi working and your imei is not null?
wifi works, IMEI exists, says Sim card 1 is "PERM locked".
I'm on H93020d_00_OPEN_EU_OP_0326.kdz now.
The same Sim card works perfectly in my LG G8s

Debloat Japanese Apps like Docomo Contacts App from L01K V30+ ?
How did you do that using ADB ?
With or w/o Root ?
Can you or anyone explain ?
