I recently purchased the HTC Inspire 4g and wanted to root it. I downloaded the ace-hack kit and followed the steps in the manual to root. My Android version 2.3.5, htc sense 3.0, Software number 3.20.502.52 710RD. While running the cmd it states that my phone version needs to be downgraded in order for it to work. How do I root such a device? Thanks in advance.
