Ok after trying so many times to update I finally found the solution. Steps: 1: Install HTC Sync. 1a: If you already tried the update with it and failed, uninstall and install a program called CCleaner (Google it). 1b: When installed run CCleaner and go to registry (the blue box on the left). 1c: Scan for issues and then press Fix selected issues... and fix all of them. 1d: Reboot computer to be sure problems are fixed. 1e: Reinstall HTC Sync. 2: Run HTC Sync if it isn't already running. 3: Turn on Dinc and plug it in, then choose HTC Sync on the connections menu that pops up ( The one that says Charge Only, Disk Drive, HTC Sync, and Mobile Broadband Connect). If Dinc says it can't find HTC Sync that is fine. 4: Run RUU (This step is, what I think, is the most important.) 5: Turn off internet connection. Ex: disable or disconnect wifi/wired connections. 6: Follow the steps in the RUU. Well, this is what worked for me, but your results may vary of course.
