I pressed and held the power, took the battery out and waited for 30 seconds, nothing. I just tried removing the SD, nothing. What I believe caused it, to install the Twopointtwo rom you have to update the radio/nv/wimax & err 1 other thing. When I tried to flash the radio (yesterday) I got an error and it aborted. I didn't think anything of it and rebooted the phone but it was stuck on the evo screen. I was reading that updating the radio can short the motherboard if you try the GSM radio update on a CDMA or visa versa.
I downloaded the file from a guide on how to flash the EVO 4g, so it should have been the CDMA radio I got. I can only assume this was the problem. A guy told me it was also bad that I took the battery out when I saw the phone icon with the arrow eairly this morning. I had pressed power and tried vol up and down before I pulled it though. It was stuck. Or perhaps it was just my bad luck. In either case my phone is completely dead and aside from it magically coming back on later today or something I fear I need to get a new one.
I made exactly zero calls with it and only had time to play with it for about 10 minutes outside of trying to install the TPT rom. lol. The only silver lining here is it wasn't an iPhone 4 and I can find EVO's on Craigslist for $175'ish all day long.
