[HTC Desire 300] obieq:
Hello as in topic.

I cant fix this. When i turn the phone on there's logo and 7 vibrations and phone hangs out.

If I use VOL DOWN + POWER and run Fastboot phone is recognized by windows and cmd fastboot but when I go to Bootloader phone is not recognized (USB enumeration failed).

I have tried to upload a recovery with fastboot and to unblock bootloader by HTC Dev website (other devices) when I try to use .bin file there's Question If I want to unlock bootloader I can choose yes but when I use POWER nothing happens. Same with commands fastboot oem unlock / fastboot oem lock (there's only 3 dots . . . and nothing happens).

There's no code for this but I get signature verification failed response when I am trying to flash recovery.img. Without this I can't probably use TRWM or Clockwork recovery.
