Dead N73.

[synth1]

First i want to say Hello to Everyone because i'm new here
I want to ask about support or some sugestions, help.
Today i've killed my first phone - n73, and probably it was my fault.
I've try to unlock it but i loose the power when bb5box was writing the PM308. (power conector jump out from pin.) after that phone freeze on full reset.
My second mistake , i've mix with the cables today, i've add few cm's to test point cables. I dindnt check the support before otherwise i'll eft the cables with normal lenght.
Now i dont have connection with the phone any more (Cannot detect phone on FBUS interface).
Phone is not turning on at all. Windows is looking far a drivers when i try connect it with normal usb cable but thats it.
I try diffrent n73 and everything looks alright, box is still reading phones normal.
Is there any chance to bring to life this phone? probably full flash colud helps but i dont have any flasher to it, like jaf etc.
Can anyone give mesome advise? some sugestions? or i kill this phone for good?
Thank You for any sugestions and help.
