Hard Resetting? Going back to the core..

[sovrce]

Is it a "hard reset" I want to do if I'm trying to go back to the way the phone originally was (after the upgrade)? I flashed to DCD's 2.10 ROM (Rev A & GPS) a while ago and all was well. Recently I've been having some problems (things just *freezing*, beyond use) and I've decided that rather than forget it ALL and go to a RAZR2, I thought I'd give it one more chance from a fresh start.

SO - how do I do it? I don't want to get stuck in the bootloader, my only real concern. But I do want to revert back to the original, fresh ROM settings.
