I have an Europe LG H960A 32gb with unlocked bootloader that used to have Android Nougat. While trying to manage with the TWRP recovery I accidentally cleared all the filesystem (Android included) and rebooted with no OS or ROMs. So now I can't do anything, and the phone is stucked on download mode, and TWRP seems to have been cleared too. I tried literally anything to flash back a stock firmware (LG Bridge, LGUP, LG Flash Tool) but without success. The only thing that apparently did something is LGUP (DLL fixed) with an KDZ install, but always gets 0x2000 command error everytime reaches 26%. What should I do?
