Default need help, 7 vibes and installing nodo


Im new here and first time on doing anything like this to a phone and would like some help.

Im having a problem with it which is one of the reasons why im here to fix it,
the phone goes to the htc boot screen and vibrates 7 times, im guessing its overheating from what iv read on here and the phone it self works if left off for while you can get the phone running normally but after approx 20mins of using the phone it reboots a few times then stays on the htc logo at vibrates 7 times. (my pc detects the phone normally and in usb mode just fine)

from what iv read the only way too fix this is to install a nodo rom but there are so many different ones i have no idea which ones i need to use
so any help here would be great
