T-Mobile MDAIII english Version hangs on Boot loader V2.01

Hi to all,

after a few hours i read some posts for "how to upgrading" a MDAIII i give up.

I had to try update my englisch MDAIII from T-Mobile with the boot loader Version 2.01 to the actually german Update. the update fails, and now the MDAIII starts allways with the Boot loader. (first serial, and when i put it into the cradle with USB v2.01

So i will test some tips from this great forum, but nothing it works,
when i will update with a standard update file the display of my mda
displays Radio Stack update and my PC tell me after a while "please contact your Vedor for helping"

I have nothing idea how i become my MDAIII run again.
(With english or german OS)

normaly i think i must use the normal Update from T-Mobile?
But which? My MDAIII is english, but i don´t know it is come
from united states or from england or...???

can i update the boot loader to 2.06?

Now i´m very tired about this.,, uhhh i see im not a expert.. ;-)

Know´s anyone a solution to run my MDA again?

(i have not make a Backup before :-(((

best greetings to the far world!!

Thank you a7.
first all is the same problem. when i will boot the new firmware, the message diplays on my computer "please contact vendor for helping"
(at the first step from the update software - the radio update)

but:

i renamed the file radio_.nbf to radio_.nb

after restart the update utility the mda is flashing !!

but the radio version is now always old ;-)

puhh, tht is not very easy..

i cannot update the radio.
