I have recently purchased an HTC Wildfire A3335. For those of you don't know, this is a special version of the Wildfire which has a UMTS 850/2100 Radio. Anyway this phone seems only to be available heavily branded through an Australian operator, Telstra.
Due to the hideousness of the branding, I naturally wanted to get rid of it. This was pretty easy-- Cool-- I now have an unbranded wildfire A3335.
Now, when it was flashing (using an HTC RUU exe) I noticed that it was "Reflashing the radio". I freaked out. I know this phone has a special radio in it and of course the unbranded RUU is for the 900/2100 UMTS version (A3333).
So as expected the phone has lost its very special 850MHz UMTS and now only works at 2100MHz (I doubt the phone has suddenly gained the ability to use 900MHz UMTS as it has the wrong chips in it)
The Radio image for this phone is available inside the Telstra RUU on shipped-roms.
My question. Is it possible to extract the radio image out of that and flash it in with the rest of the unbranded system? And hopefully get my 850MHz UMTS back. Currently it appears that the answer to this is no due to the lack of signing?
