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?

Hi Guyz, so i managed to brick my phone yesterday. Was running Optimus G3 and decided to flash CloudyG2 3.3. Followed the instructions did a full wipe but when rebooted LG logo would flash for a split second then screen goes blank. The screen is on because can see the back-light but nothing boots. Tried a couple more restarts but the same thing happens. I did take a TWRP backup prior but when i enter recovery mode and restore the backup, when it reboots i get the LG logo then the android animation but then it freezes/stops on the Android text.
I then tried flashing stock rom via LG Flash Tool, downloaded both kitkat and lollipop kdz files, entered download mode on phone and got the firmware update message, went through the process of flashing with the flash tool but when it comes to the software upgrade part, it gets to 2% then fails. with a message - Upgrade stopped due to an error. I get this message when trying to flash both kitkat and lollipop kdz files and i have tried on both windows 10 machine and windows 7 laptop.
As i have access to recovery i have tried restoring backup many times but it just gets stuck at after the android animation, i guess my next step is to try the tot flash method but im struggling to find a clear guide on how to do this so any advice would be helpful.
Cheers, Justin.

Thanks, actually shortly after i posted question it fixed itself... i tried flashing lollipop again, the software upgrade started and it got to 2% then error. I left the LG flash tool open with the error on screen, disconnected phone and rebooted the phone... it went past LG logo and got stuck in boot just after showing android animation, so then i plugged in phone (wanted to see if could access phone via windows whilst stuck at boot) and after a couple of minutes the software upgrade window started on my pc so checked phone and it had switched into Firmware Update mode and was updating... so all good now!! Lollipop has installed and phone all working.
^^^ This may help someone with similar problem.
Thanks,
You should've flashed the kitkat bootloder before.. If you want to go back to cloudy ,flash the kitkat bootlader again..
so ive dirtysanta my h915 to install twrp to then install oreo with root....
well something messed up, i was able to boot into system fine, i went into recovery to update twrp...then was unable to boot back up into system.
i have recovery, download mode and fastboot still.... but no system.
lg up shows unknown COM 4 H915 -- US996
Im lost on what to do to hopefully fix this..... i regret this so much
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

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.
So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
Got an H910 which has been fine for the longest time. It was running LOS17.1 with nothing else besides magisk installed. It was also the official release.
A week ago i decided I wanted LOS18.1 instead, but I got multiple E1001 errors unable to modify System partition.
Someone suggested I went back to stock and root again or something, so i flashed Kitkat zip and have since been stuck on an endless loop of "no command" recovery mode.
my device is still being picked up as US996, but despite all my attempts I can't seem to be able to flash anything. LGUP always succeeds but the second the devide reboots the "erasing.." screen is shown for a split second before going into an endless loop of turning on and off the screen with "no command", and still showing as US996.
in theory fastboot was already unlocked but I don't think it's the case anymore after the kitkat file thing.
I'm currently out of ideas. Am I missing something?
Any help would be appreciated.

Did you flash the nougat kdz in the dirtysanta root guide? I had a kernel crash problem and started over to fix, but I didn't flash a KitKat ROM in LGUp
