3.51 M33 Custom Firmware Installation

This requires 3.50 or below. If you have 3.50 or below you must downgrade to 1.5 and upgrade to a custom firmware for you to install this. Full tutorial on this can be found on http://www.pspdiscussions.com. To do this you downgrade from 3.50 to 1.5 then you upgrade to this firmware. 3.51 M33 Custom Firmware, it is pretty easy to install, but I made this video to help out the people that keep Instant Messengering me for help. I would have to say this is pretty much just like Dark_Alex's firmware, but with a few bugs in it.

NOTE: If you missed it in the video I said to name the 3.51 EBOOT.PBP to 350 you actually need to name it to 351.
