I am currently running MODACO 2.2 and I saw that 3.1 was out there. I downloaded the core and flashed it. Everything went successful. However, when I reboot the phone, the phone never goes past the HTC screen. I have been patient (I gave it about an hour) still nothing. I restored back to 2.2, but I was wondering if I was missing a step that I was not aware of. I tried wiping the phone, but that didn't work either. Any suggestions would be nice. I just figured it out. modaco 3.1 is for GSM phones. I am using a sprint CDMA. Oh, well guess I just have to wait.
