Boot images were flashed ok, but after reboot it was same. Loading and black screen. I dont have a photo (only this on nonworking Pixel). Firmware is correct, at least checksum said so (i have a bakup of my phone on other disk and there was original boot.img and patched one, so I can check them with original one). Now P6 is start working, blank. So I need to setup all over again... First I will root it and then further.
About flasher: maybe next time, now it's over... phone is empty.
