Custom ROM to Stock ROM. Help

[Bonz]

Hi,

I want to revert back my H990DS from RR Oreo ROM to Stock. I did use LGUP to flash the KDZ file. Question is how long is the initial boot after flashing? currently at LG logo for about 15 minutes.

I don't know if LG phones are same as Samsung but on Samsung phones you have flash the official firmware and after that boot into stock recovery and do factory reset.

hope this helps
