Default [Q] Hard bricked my mb886

Hi guys! After a failed firmware, my mb886 is bricked. If press the button(Vol+ Vol- Pwr), nothing happens. And RSD doest detect phone.
Fastboot just doest work.
When connected to the pc green LED lights and it shows up as USB Input Device and HID-compliant in device manager. Hardware ID is (USB\VID_05C6&PID_F006&REV_0000).
Under Linux, defined as Qualcomm inc.
Now it's for parts or have a way to recover? Maybe someone has a JTAG pinout for mb886?
And sorry for my english))
