Upgrading the BT manager

[stas12]

Hello

I bought the qtek 2020. version 1.72.00WWE
radio 1.14.00 and windows 2003

I want to upgrade the microsoft BT manager to widcomm... Is there any way to do this without a rom upgrade?
if no, is there a detailed guide how to upgrade the rom to WIN2003SE with step by step?


Thanks.
