[Q] Samsung Epic 4g - Problems with Phone Modem

I just switched from the old Epic Experience to Cyanogen 7, the latest nightly version. When my phone boots up, everything works except for my phone, text messaging, and 3g. The phone keeps looping from Airplane mode off to on. I can't even make calls but wi-fi works.
I tried to replace the Cyanogen Rom with 4 other roms with no luck. It just keeps booting back into the Cyanogen one. Now I'm stuck. I've booted to CWM several times now, wiped the cache and dalvik and nothing. (I get the /sd-ext error but I heard that doesn't matter).
Can someone please help or direct me to where I can find help on the issue?
I ended up just following the video here:

It was very helpful for using Odin to put my phone back to stock. I don't know why but I can't get my phone to install any new ROMS. I just tried installing the one that says "ERA" and I get the Samsung screen on boot up but it freezes. :-l Why are ROMs better than having root access to the main stock?

[Q] Phone restarts after calls

Dear All,
I have the following issue: if I'm on GSM / WCDMA auto Network Mode, my phone sometimes reboots itself after call.
It was an issue on stock ROM and it is on CoreDroid as well.
I've flashed the newest radio, but it didn't do the trick.
Any suggestions?
thanks!
