Every time I've had a custom ROM installed, whether it be Cyanogen, BB, or Ultimate Droid (what I'm currently using) the phone will reboot itself. Now, I've only noticed this when it's trying to load something sometimes it'll freeze, then just completely reboot. It NEVER does this on the stock Android OS, just custom ROMs. I'm not over-clocking or anything. Right now I'm running UD 8.0 and a chevy kernel. Every time I install a ROM I will Wipe Data and Cache. It's almost frustrating because the custom ROMs run faster/smoother than the regular 2.2 build, but I hate the little reboots every so often. Or sometimes I'll get "Network Error" when in the Market and I have to back out of the app and try again. Any ideas? Kind of frustrating. I have yet to have a ROM to work flawlessly with no hiccups or errors. Does everyone have these kinds of little bugs every once in a while? Maybe I should try BB again? I didn't have it on for too long until I went to UD 8.
