PSP Slim CFW Questions

cypherx · 09-20-2008, 02:59 PM

Hey, there,

I'm pretty new here, (and to the modding scene) and I'd like to know if it's SAFE to downgrade a psp-2001 (Slim) to 1.50 in order to re-upgrade to 3.90m33 or 3.72m33. If not, how can this be done? The PSP I'm trying to work on is currently sitting at 3.90 OFW.

Thank you much!

Thanks a million for a quick reply, but during that time, I already figured out how to do it.

I used, instead, a copy of PSP Pandora Deluxe to make a MMS with 3.90m33-3, and it went directly to that. (Not a user-friendly program, but very powerful.)

Thanks again,
