Ok, I was able to go to maskrom mode, erase SPI flash and reflash SPI flash again. Still the same problem, blank screen with backlight and green led when I have connected my NVMe. I tried to flash older SPI from pcm720, but seems I cannot find the correct one what works, cause it neither boots, but the LED is green from the beginning.
BTW, which OS are you guys using?
