I got the radio file from this thread as well, but I just don't get it. I got the RUU.exe from the HTC site (stock rom) and the radio file. Do I somehow install the radio first, then the stock rom? Then I can go custom? I already have the rom I want installed, it's the R4R reloaded (with manilla 2d). It's in a .zip folder that has a RUU folder inside.
1.Do I just unzip the RUU folder, put the radio into that, and run the rom update utility? I'm kinda lost here...What order do I need to do this in? I read Dash's tutorial, so I think I'm on the right track, but the stock rom wouldn't install, so the radio thing has me confused. And the order to install these things...
the stock rom will update if you are using your providers. the only reason it would say that it wasnt the correct provider is if you were flashing a custom rom or another providers rom to your phone without relocking first... if you have it unlocked you will be fine and the flash will work without troubles.
