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.
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.
Having a helluva nightmare right now with this LG V20 US996. Updated it to US99610f with no problems then proceeded with DirtyElf to unlock, however instead of going with SuperSU I went ahead and popped on Magisk 11.6. After exiting TWRP my device kept rebooting back to the LG logo so I went to reload the KDZ for 10f in download mode and for whatever reason it kept getting stuck at 4% in LGUP. I was still able to access TWRP so I went there and flashed the 10f/with root found on XDA and that looks like it fscked things up even more now as the device keeps rebooting to the warning screen you get when the bootloader is unlocked. I can't seem to access TWRP anymore either! I can however still access download mode, but same thing as before getting stuck at 4% in LGUP... any suggestions?!
Why aren't you asking in the Dirty Elf thread?
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.
I'll try to summarise it.
Unlocked my bootloader.
Tried rooting by flashing twrp and then installing supersu (i think i installed a corrupted version, as my phone did not go past the logo).
Deleted all system and cache to install lineageos, hoping it would fix it. It did, but i was unable to use my mobile data.
So i tried flashing the stock firmware for my phone ( H87020f_00_EEO_GB_OP_0817.kdz ) using uppercut, as LGUP did not recognise my phone.
Both twrp recovery and lineage were deleted.
It's back to the old boot sequence for LG phones but it gets stuck at the LG Logo "LG Lifes's Good".
The boot up sequence is, Bootloader unlocked message>LG G6 ThinQ>"Erasing">Bootloader unlocked message>LG G6 ThinQ>LG Logo. and it just stays there, tried waiting for 3 hours (i fell asleep), and it was still stuck.
I seriously need any help i can get for fixing this. I know that i'm an idiot for not backing anything up.
Fixed it

Click to expand...
Click to collapse
I fixed it, i installed the oldest version of the stock firmware using uppercut and now its working again. That was easier than i thought.
