My wife's Dinc has been having issues lately - locking up, excessive battery consumption, not receiving texts...on and on. I decided to reflash her phone back to 2.1. I followed the instruction in another thread using PB31IMG.zip to bring her phone back to it's original state. When I powerup into HBOOT, the phone checks the zip file and then gives the error - Main version is older, Update fail. I have read through several threads for a solution but all are assuming that the phone has been rooted. This is not the case here. Any suggestions??
