There are plenty of posts here at XDA that would have told you that as of now, this radio version can not be downgraded.

The search function is a beautiful thing .... :D

I have same problem, and have found WM6 (one of the official ROW roms) works ok with 1.54.30.10. WM6.1 is much worse.

If you are having a lot of problems dropping calls etc try going back to an official WM6 ROM.

I don't have this version. but this version is used by the main carrier's official WM6 ROM so it can't be that bad would it?

I have not tried this so I am not sure if it works. But I have an idea. If you install the hard SPL from Olipro. In step 2, it writes an older radio file (I think it was 1.15 or something) onto the device. if it works then you can flash it with any version of radio you like.
