DHD 1.84 Downgrade??

[Guest kickasskev]

Ok people I'm trying to help a friend root and custom rom his phone, his firmware 1.84 and t-mobile branded, from what ive read i have to downgrade it and s-off, and the only way i have found to do this is on the xda site and it involves ADB which I dont know a lot about, is there another way around this a simpler way??

Any help or links appreciated :P

Guides on XDA are the way to go.
