Proffieboard completely unresponsive I already rebooted it and did that whole thing still nothing

Please help me

I have a board that needs to be plugged to the USB, then keep pressing BOOT, and tap RESET while BOOT is pressed. Only then it starts.

is this while the battery is in? Also byplugged into the usb do you mean the micro usb on the actual board or the charging port

There is zero information in this thread, which makes it impossible to help you.
Is this the same as the other thread? If so, why post another one?
