Hard Reset Samsung SCHR500 cell?

[littleaprilgirl74]

Phone thinks the text memory is full, but the text menu shows everything at "0" with nothing to erase. I've removed battery, factory reset etc. No help. Will not send or receive text messages because of the problem. Was told to take it in for repair. Will a hard reset help? If so, how do I do it? Thx.
