Thanks, however I've already found it :)

Also I've tried to flash every single file of extracted payload (yes, i know that not every img is slotted, but I didn't want to write every single command by hand, so I've scripted it ;) Also didn't know which are Critical, simply I've tried to flash with stock as much as I can using fastboot).
