Trying to upgrade T-Mobile MDA IV

[andynumpty]

Ok please be gentle before you read.

I'm trying to change the offical T-Mobile ROM to the newer offical 1.93 from HTC.

I have download the ROM exe from this site but when it trys to install ROm an error comes saying "Error 244 invalid model ID".

I have tried searching & looking through loads of threads but all seems very complicated to a numpty like me!

Can some body please talk me through in easy steps to help me?

Thanks in advance.

You have to install hardSPL first. I prefer 1.40 from olinex.
