First, regarding the possibility of bricking my system: I know it's supposed to be extremely minimal, but what I'm wondering is if that chance of bricking it occurs every time you load up the LCFW after installing it (through the Fast Recovery tool), or if that chance only occurs when you install it. As I understand it, running the Fast Recovery does something with the RAM, and installing does something with Flash memory. So it seems like it shouldn't be a problem, but I wanted to clarify.
Second, if that risk only occurs when you first install the CFW, should I maybe just use a HEN? It looks like a HEN only deals with the RAM, which seems like the absolute safest thing to mess with, and really, all I want to do is play emulators. On that note, are emulators in any way dangerous?
