Help Me to relive my MDAC PLS!!!

[Herian]

Guys i have a big big problem here.... my mdac is dead, is in bootloader mode... I have tried to flash the rom how is described here http://forum.xda-developers.com/viewtopic.php?p=144686#144686 but i see the screen of the rom version empty (i tried several times...)
So i decided to do the reflash by an sd card, i downloaded the nb1 file from ftp (if you have a .nb1 file to send me i apreciate that :D )written it on the sd with ntrw, inserted in my mdac (blocked in bootloader) but nothing happens! Reset and reset but nothing!
What can i do?! How can i relive my mdac?!
HELP ME PLS!!!!

P.s. when i reset it with the sd inserted and the usb connected the pc says that is an unknown USB device... if i reset again without the sd inserted it reconize the mdac how a ms sync cable... the ActiveSync USB check is unselected...
P.p.s I have posted the same topic in the giude for the sd upgradig... sorry for that but i'm disperated!

* first uncheck the USB connection of active sync.
* run the command ntrw write rom.nb1 x: in the command prompt window where fixed.nb1 is the filename of the ROM and x the SD card drive letter.
* Put your SD card into your MDA and get your MDA to boot loader mode again (power+camera+reset buttons). On your unlighted screen you will see it says serial wait and after some seconds it will say (Press Power to flash).
* Do as it says and it will start flashing. When your MDA reaches 100% flashing, it will check the checksum. Don't worry about the message Checksum failed - Flashing failed and soft reset your MDA.

Hi had already done this operation... but nothing...
i had to do with the mda connected to the pc? On the screen don't appear nothing... only serial v 1.00 (or usb v1.00 if is connected at the pc)
have you a backup of your rom that can i put on my sd? So i'm sure that it works...

I'm going crazy...
I don't have the backup rom of my mdac, how can i do? There's somewhere an original rom for the Tmobile German Mdac? I read that i need to overwrite first 416bytes of the rom to upgrade with the first 416 of the old rom, but i haven't it...
i'm a really newbie! i hope someone helps me... don't leave me alone :cry:
