We’ve posted on this software for the Touch Pro in the past, but now we are happy to report that you can now assign any action to any button or button combination thanks to Xda-Developers.com member, tarkim! This software is device specific too, so don’t try it on any other hardware but the HTC Rhodium “Touch Pro 2”.
The software is available in the XDA-Developers thread HERE. It requires two cabs to be installed, the phone to be reset, and then you follow the simple setup steps. I am able to setup my PTT and Mute buttons on NRGZ28’s “Leo” ROM. Let us know if you’re successful or not!
