I installed a CM7.1 over a custom 2.3.5 installation on my Samsung Galaxy S I9000. I did a full wipe through CWM as well as wiping the cache, as explained in the SGS installation instructions. The installation completed without any errors, but when the phone booted the process com.android.phone force-closed. When I dismissed the error, it force-closed again within less than a second, and continued doing so.
I rebooted into recovery and made sure to wipe everything, but nothing helped. I finally reverted to my previous ROM in disappointment.
What could be the causing these force-closes? How can I install CM7.1 successfully? Is there any specific kernel I should install? Any specific modem?
