Corrupt Flash and Cyclic Rebooting of Rizr Z8

mates,
having mistakenly unplugged the usb cable whilst the flashing of my rizr z8, the phone freaked out and ended up with complete crash.  the phone is trying to boot; you see the moto icon followed by hellomoto text during the booting and all of a sudden the screen becomes total yellow, blue or magenta each different time. well, this seems to be the least of the problems because, no matter what i have done to remedy this default (properly reflash the phone) to enter the flash mode via pressing * and #, it did not help.
i am, for a long time, into the moto modding and reading almost all the major forums but i was unable to find a specific solution to the thing i am suffering from lately. so, anyone of you over there to advise / suggest what i should be doing to recover my dead rizr z8 as i don't want to hassle with some incompetent service centre.
best to all...
