[Q] Bricked?

view story

http://forum.xda-developers.com – Basically I’ve been trying N4 conversion and everything went smooth to the point where phone should reboot but never did. The only signs of life are short red led blink when I holds power button ( holding power+ vol up or power+vol up+vol dawn do not produce any effects) and my laptop detect an usb device: qhsusb_dload and could not find drivers for it. Any suggestion? :crying: (HowTos)
