downgrade fail - bootloader version 2.05

[hennessy]

Hello FELLO APACHE OWNERS !!!

I just got a good verizon 6700 apache on ebay
it loaded up and I began fixing it up
as I began to get used to the phone I began interested in wanted to upgrade it to WM6
I loaded it in BOOTLOADER and the phone said "Serial - V. 2.05"

I tried downgrading the bootloader... since to my knowledge, that is what I think I have to do (complete noob sentence)

But after reading alot of information I found I tutorial on this site explaining how to do it using MTTY 1.42

I loaded it up ... typed "task 28 55aa"
and my phone doesn't boot up anymore

still have bootloader 2.05 on
can't turn on
can only go into bootloader

please someone help me reset and try the right procedure ...
HELP HELP HELP !!!
