Default NC2 issues

Hey guys. I am not sure what is going on. I am not sure if its a hardware issue on my phone, or if its a bug on NC2 radio or what. Anyway, back when NC2 first came out, and I didn't do all the reading right I had upgraded it. Well I didn't like the fact you couldn't create ROM slots yet in SafeStrap with NC2. I had flashed my factory ROM slot with one of the ROMS that were available at the time and at least twice a day I would have to reboot the phone because it would just start running VERY VERY slow.

I ended up downgrading back to MJE and figured I would wait until SafeStrap had working ROM slots again.

Well here I am a few months later, SafeStap now supports rom slots...so I upgrade back to NC2, update to the latest safestrap and flash a rom...same issue....Does it on the factory nc2 rom as well....What gives?
