Hi, I currently have 3.90 M33-3 custom firmware for my psp and I want to upgrade to a more recent custom firmware. But im to sure how to do it. If some could explain to me how to update my firmware id appreciate it. Also whats the best/most recent custom firmware out right now? thanks.
The latest and greatest is 5.50 GEN D-3. Grab the 5.50 GEN A installer along with Sony's 5.50 update. Rename it to 5.50.PBP. You also will need GEN B, GEN B-2,GEN D, GEN D2 and GEN D3 installer. all available at PSP-Hacks.com
