Hi dear community,
I have flashed H915 KDZ on H910 LG V20 to unlock bootloader but without success because I was unable to ger into twrp but that is another story, how can I get back to H910 ROM since I have made a dump with LGUP (too many files and I do not know how to proceed)
Thanks for your precious help.

Reflash the H915 KDZ until you get TWRP. You can flash your DUMP with TWRP I think?

The only way to go back to stock H910 is to first root your device and flash the stock H910 twrp zip file.
