Okay, I want to upgrade my PSP's cust. FW because I haven't done so in quite a while.
I saw that "5.00 M33" was recently released, but I'm afraid to update because isn't "M33" a sort of 'different' kind of Firmware? Sorry, I know nothing about this stuff.
Will I have to upgrade to an "M33" firmware before upgrading to 5.00 M33?
Again, my firmware is currently:
3.40 OE-A
