Re: why is my phone frozen after trying to reboot it?

Define "reboot/refresh". Reboot is either restarting or turning the phone off, then turning it on. Refreshing could mean anything, since there's no "refresh" function in Android.

I assume you mean you took out the battery then put it back in; If the phone is working with no battery, I'll buy it - name your price.

The problem could be anything from you doing something wrong when you did the "reboot/refresh" thing (which is easy to fix in a Samsung phone - just reflash the ROM at very worst - so you waste 15 minutes), to the motherboard choosing that time to go bad (which is an expensive repair. It's not something that can be analyzed online like this.
