Re-Flash with a Official Stock ROM. If you are with Sprint then Flash the new ROM. The radio will reflash in the process. Otherwise use the newest .exe from your carrier....

I have the same problem when I run the ppst , unless it's the patched version on here. If you reflash you should be fine. Hard reset doesn't touch the radio... Take care and double check prior to flashing anything especially if it relates to the radio....

Hope that helps..
