Dear XDA community
Recently I had bricked my LG G5 on LineageOS (red boot flag - system integrity check problem found or something like that) and after that I reflashed the firmware with LGUP and various kdz files. Everytime it works good but I get the common error on boot (can not match cust for NTCODE=[,]) but still it is not an issue. Yesterday I found out that i can not longer access recovery even after flashing TWRP from fastboot, it seems like the factory reset prompt just vanished. I tried many combinations for accesing the prompt but it doesn't show up and the device boots up normally (LG logo -> orange flag (bootloader unlocked) -> LG logo)
I hope that someone will find a way to solve this issue.
Also i noticed that LGUP does only a dirty flash and everytime it leaves some system apps from "clean europe kdz... with Orange Jeux app"
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?
How and how to restore the smart, please tell me.
"Frankenstein" from 996. Unlocked the bootloader, but could not overcome the safety net in magisk .. I flashed 998 30b, and then blocked the bootloader. Immediately upon startup, it writes a message in red font "Your device has failed a routine safety check and will not boot". It enters fastboot mode, it is seen by the computer as an andoid fastboot device. The fastboot devices command does not detect the device ... It enters the download / update mode - the computer does not see it in any way. I reinstalled the drivers. It costs win 10 64bit. Lgup 1.14.3... Help please.

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.

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 ?
I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.
There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.
