I am holding power for 10s and it is not working. Later when I press power button it's not booting. Screen stays black and my computer doesn't detect anything (RCM mode), when I connect it via cable.
I have AutoRCM and tried it. Payload (Painless Linux Windows) showed no errors, but it didn't worked. Now I have black screen and I can't reboot to RCM, holding power button doesn't seem to do anything.
