Some help here please? Bricked lg g2 d802

Ok guys look, I bricked my LG g2, made it via tot method cuz nothing else was working (no recovery, secure boot fail) (no Rom, already wiped) (download mode with LG flashtool 2014 stuck always at 2% and sometimes crashes on read phone info) and also I'm encountering a cdc driver fail.
Whatever tot method worked, dunno how but did.
Now I'm on rooted 4.2.2 unknown carrier stock Rom.
What now? Can I freely flash? Do I need to upgrade the bootloader and then flash? How is that done?
I just want cloudystock but I'm really afraid of upgrading after all that fails and this brick. Can someone help me please?

LG V20 F800k cant flash stock rom.

Hi i am new in the forum and have a issue with my LG V20 F800k. That what is on back of him( under battery)
When i get him he have some koreantelekom firmware. When i check in settings -about- that say H918....
I flash with TWRP "H91820f" and he is so bad. Mobile restarting all time, wi-fi don't work all time. And when start after lg logo i have T-Mobile logo. No more koreantelekom: ). Maybe bad rom

Put him in common folder in LGUP, but when i want to flash stock rom (upgrade bottton in lgup) process start, but after 17 seconds i got an error in setup (click herer to continue) . When i press again display me command port error-3
Can someone help me with flashing stock rom?

There is a log file when you do lgup, it might enable a dev to help you out. Post it.
Where can that log file be found?

help how to clear system cache on lg g6 h870ds (gcc)

someone please help to bring back my lg g6 h870ds .(lock bootloader and cant fastboot ) all i can do is watch my lg phone on firmware update. if i restart it just always on same phase ( do not plug the usb connection until the process complete) . i already try to attempt to factory reset but it always stuck on system update i mention .
i tried LG UP and LG bridge but the same results , i downloaded the new virsion og LGUP .store .dev . lab and i have correct kdz and hash but it always says 0x20000 0x80000202 invalid response but the time i tried LG BRIDGE it fails and also changed the firmware of my LG G6 now i have to update to latest verion of LGUP and common dll . it runs ... but theirs new dialog says 0x7000 KDZ image corrupted but i double check it and it is a correct hash .. even in previous attempts it is always 0x2000 0x8000202 always on 11% to 12% of load until is stop . now in this new one 0x7000 thing its the same 11% to 13% of load until it fails . my suspicion about is maybe it just the same error but it just change its error message .
i just want to know if theirs a way to bypass its LGUP tool to clear the system cache of my phone because before i plug it and turn on debugging i got errors on LG firmware app it self it crash and stop always (my phone is alive in that time) the app that u used to update your lg phone without computer
i see a thread that he make a dev patch of LGUP that unlock all features and i have its copy but is on LG V20 and not compatible on my lg g6h870ds ( the LGUP says on boot up . invalid dll for your lg g6h87020q please install proper dll ( .msi))
if theres anybody can help where i can find modded dll patch LGUP to my lg g6 h870ds (GCC ) so i can flash without restrictions
ps sorry for my bad english
I CANT USE UPPERCUT BECAUSE OF NEW UPDATE OF MY FIRMWARE AND CANT DO ANYTHING JUST LGUP ITSELF . BECAUSE I DONT HAVE ACCESS ON BOOTLOADER AND FASTBOOT
