Working great for me so far. Clean wipe flashed deodexed 1.1. Appreciate the ad blocking, advanced power menu, and the ability to uninstall some of the google apps that I don't use. Thanks!
You probably need to flash the radio that matches the firmware, 3.18 is not the current radio for the 2.15 firmware. http://forum.xda-developers.com/showthread.php?t=1694012 is where you will find the radio, it is the T Mo Germany 5.08.
I would think it might stop when it gets to the part about needing to configure for a carrier. Are you downloading a carrier (ATT, etc) based update?
