Okay, well I plan to do a bunch of customizing on my PSP, and I have HarleyG's custom firmware v0.2 installed. First off I would like to know, what can't the Recovery Mode protect me from? Like with a custom font, how would I get the 2.00 update running on it? Doesn't the update use the installed font, or is it somehow integrated into the update?

Stuff like that basically. I just want to make sure I don't end up with a non-fixable brick.
