Stuck on Firmware update mode - LG V20 Questions & Answers

Guys, I have a US996. It was rooted using DirtyElf method, had WETA rom installed. I had a problem when I was flashing kernel, and got stuck with a crashing screen or fastboot mode. After some different procedures, managed do flash kdz using LGUP tool. Now, I don't have the crashing screen anymore, but I'm still stuck on Firmware Update. I can access Fastboot mode, but when I try to fastboot reboot or fastboot reboot-recovery, I always end up on Firmware Update. Apparently, my bootloader is still unlocked, so it seems tha kdz flashing was not full,. Any ideas? Any help would be much apreciated!

need to reinstall twrp. then from twrp you need to reinstall a new rom.

[Q] LG G2(F320L) not booting after OTA with stock recovery with TWRP aboot

Hi,
First of all i committed a mistake of thinking that with TWRP aboot + stock Recovery i will be able to do OTA upgrade, which made my phone not booting, undetectable by computer and majorly not getting the LG Flash download mode by pressing any combination of keys., Stucks at LG logo.
Device: LG-G2(F320L)
KDZ stock: F320L21V_00.kdz
1. Flashed this kdz using LG Flash Tool 2014.
2. Flashed from F320L_AutoRec.apk, the images only aboot, and recovery.
3. From DorimanX project generated the boot.img with StockROM(F320L21V_00.kdz) version bootimage RAMDISK.
Everything was fine., till then.
After that, i got the OTA pop up., So, thought of installing OTA. As I had already faced the TWRP bootloop once and in some post i remember i read flashing OTA needs stock recovery image. Here is the place I commited the mistake. So, signed the stock recovery with aboot of TWRP using loki_flash. Accepted OTA. Thats it.
From then, no booting, no recovery, no adb, no fastboot, and unfortunately NO LG DOWNLOAD MODE also it goes.
When i try to go TWRP, it stucks up after the initial TWP message.
And pressing some key combination, the device goes to LG service mode, and showing the IMEI and some list of 3 options in korean which i dont understand. By pressing any of the option device reboots and stucks with LG logo.
Even my device is not shown up in the ubuntu, when i checked "dmesg".
Can anyone help to get the device into Either download mode or fixing the boot.
Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Good luck
No solution yet?
The phone is still in the same state. Can anyone please suggest the solution to make the device working? Thanks in advance.

Back to stock recovery 2017G B11

Hello i have out of the loop for quite some time, and i flashed TWRP at some point in the past. but now i wanted to update to 7.1.1 and i can't when i try to use the official zip from german zte is says that the update failed. and when i try to get into recovery there is nothing or boot loop i tryed axon7toolkit and unbrick through EDL option but MiFlash fails to detect my phone. and i tried reinstaling drivers twice. Any idea how to get out of it? Btw i can use the phone just fine. But i would really like to move to Nougat
EDIT: for some uknown reason axon7tool on the nth try managed to flash the recovery. Before that i opened zading and his install WCID drivers and rebooted and that helped so SOLVED

[SOLVED]![H870]Device keeps going into download mode after interupted Uppercut flash

Hello there.
I unlocked the BL yesterday and flashed TWRP and then AEX latest Oreo based ROM. It was fine, but since I came from Oreo, I did not have fingerprint sensor working.
So I wanted to go back to Nougat and then flash the AEX from there. Uppercut didn't recognize the phone so I installed a stock based rooted Oreo from TWRP.
I started the Uppercut flash with a stock Nougat system, but it was interrupted (in upgrade mode, refurbish mode doesn't work at all) referring to: error 0x2bc invalid command response code.
Later with another kdz file it gave me: error 0x2bc crc checksum error
From then on I cannot get into anything else, just download mode (in there, wildly short-pressing the Vol- and Power buttons gets me into a menu where I can turn the phone off, and I can boot into Fastboot mode. )
In fastboot mode I flash twrp and then when I try to boot into twrp by selecting the usual reset system options, it just gets into download mode again.
I could not get any kdz to install on it so far. I tried H87020C, 10D, 20A.
So now I have download mode, which fails and fastboot mode, in which I don't really know what can I do.
LG Bridge doesn't help, LG Flash Tool stops at extracting all the kdz files I gave it and LG UP also doesn't work.
The bootloader is still unlocked.
Please help me with this.
All of a sudden for the fifth trial, LG Bridge somehow succeeded to install and boot the phone via Update Recovery Error method.

Help, fastboot bootloop

A little while ago I downgraded my phone. Today I tried to install magisk with a custom rom and TWRP. It didn't work now when I boot my phone it gets into fastboot I have tried formatting it with TWRP and reinstalling the rom but it doesn't fix it. Are there any solutions (downloading to stock via erecovery doesn't work but I can easily open the erecovery menu.
Fastboot says
Android reboot reason:
bootloader 1
no
NA
reboot_enter_fastboot_common_func
I think there is something wrong with the vendor
Solution:I used the dload trick to download stock firmware
Problem 2:I reinstalled TWRP with a custom rom now my phone keeps restarting and not opening the custom rom.
try this rom
