Several people have asked if this works with version 1.13.605.7. I tried it yesterday and yes it does work. However there was a hicup. I did use the updated package with the service pack posted as well.
After the second time it installs the PG05img.zip and rebooted you again after to change some the settings on the phone. when it booted up i changed the settings and plugged it back up to my computer. Hit enter to continue the batch file and it said adb was out of date and failed to find my phone connected(didn't display a serial). All i did was restart the batch file and choose number 3 this time and it completed ok. Not sure if that was what i needed to do but it seems to be working. I've already flashed a new rom and a new radio and it seems to working fine.
