How to upgrade just the radio rom and after the pda rom

[Guest]

Hi,

I've got an Omnia with PDA and radio firmware : DXHH3.

Before I've got use many HTC device and flashed many time some PDA. My old one was a TyTN II. Since my new Omnia I don't understand what to use to flash. :lol:

I have good understood that 3 way are possible. I'am french and live in U.S.A. I have import my Omnia so he is unlocked. I wish to upgrade to i900XXHH1 for the PDA and i900XXHI2 for the radio rom.

So how to just update the radio rom of the omnia with grand prix having the best securit to not brick my device?

After howto update the pda rom? I'am not a newbie in WM mobile device but I think that the new way to flash from Samsung is not the best :D!!

thanks everybody for your help. ;) Alex
