QUESTION_will ultimate unlocker fix this phone that has been bricked?

ive attempted to unlock w850 i after purchasing advice from Mobile Unlock Codes

i did as they said using XS++,
using the firmware- W850_R1GB001_MAIN_GENERIC_RED51.mbn
and unlocker setool2lt,
SIMLockPatchGen

it was very difficult to do- complex....and i think Ive ruined the phone as it does not turn on.

any ideas?
i did not back up the gdfs (being niave)
