My brother just bought an 2.71 PSP and we were wondering what would be the best downgrade option ? (safer?)
I've heard problems with the new 3.50 downgrader that prevent use of original firmwares.
I have an Lumines UMD (bought just in case).
Another question: is it possible to come back to 1.50 with the M33 firmware ?
Thanks for your advices.
