Go back to an old Radio using fastboot?
I recently tried the radio xxkk6 but don't think it's much good for me. My phone always connects to 2g when turned on and takes a while to then find 3g. I have a full 3g signal in my area and have tried changing various settings. This was never the case with xxkk1 so i would like to go back to using that.
I have the xxkk1 image on my laptop ready and waiting. Is it just a case of re entering fastboot and using the
$ fastboot-windows flash radio <image name here>
or do i have to do something else like delete the radio partition first?
