I'd think you downgrade the same way you upgrade :) don't know if there is an issue pertaining to the 2 versions you've mentioned!

Check http://wiki.xda-developers.com/index.php?pagename=Uni_ROM_Upgrade!

thanx for reply.
let me tell you what I have done so fare.
I successfully upgrade the ROM but didn't like the features so decided to downgrade it back the older one which is orignal from t mobiles. initially it went very well but when it reached upto 25% the the Pc turned off and the MDA pro as well.
After that I cant see the full deatails it only shows no gsm and D.2.00.41 WWE,on boating screen and device information shows:
ROM version 2.00.41 WWE
ROM date 08/08/07
Radio Version . .........
Protocol Version ...
ExROM Version .............
After this when ever I tried to upload the older(orignal T.Mobile) versoion it showa an error "ERROR 120 .Country ID code" or some thing like this
or "the rome image that you are trying to use is not designed to work on your device please contact vendor web into and download the correct ROM updat".

i download the older verson from tha same source but still not working.
and let me tell you that my MDA is every thing for me .
plz if you have any suggestion i'll be waiting .
thanx

And by the way i've download this one 'UNI_TMO_TMO_UK_20039_200136_11700_WWE_Ship_RUUFix ' from t mobile site but once angain the same problem ERROR 120 country ID error No-N0-NO 38-38-38
now i wonder what to do
