no issue will come from previous rom if u did clean flash
It's with syberia os, I flashed it 4-5 days ago, for some reason keep showing me system don't responding, after that I get lock screen, tapping and buttons didn't work only forced reboot (long press power button), then I decided to flash another rom, I flashed evaluation x, the problem happened with Eva x rom, I thought maybe my bad, now I am on rebellion os, same thing the same problem happened, system not responding then stuck lock screen, I googled it, I found this same problem happened to 2 people with mido (note 4x, and they said, all asop rom after this will have the same problem)
