How to Upgrade an Old CFW to 5.00M33-6

Requirements

If you have cfw 5.00 M33-6 or later you may be interested in upgrading it to the latest stuff. So you need:

• a psp with cfw 5.00 M33-6 or later (see warning below !)
• ALL plugins disabled
• a battery that is at least 78% charged
• The XGen updater
• 2 minutes of your time

WARNING !

If you are on cfw 5.50 GEN B, then you MUST update to 5.50 GEN B2 first!!

Let's go to work!

• Connect your PSP to your PC and enable the USB-Connection
• Download and unzip the XGen Updater to your PC. Put the content of the PSP folder to your PSP. This means you have to end up with X:/PSP/GAME/UPDATE/EBOOT.PBP
• Put the 550.PBP file to the root of your Memory Stick
• On your PSPs XMB navigate to GAME >> Memory Stick >> 5.50 GEN D-3
  
  
• Select ENTER and press X
• Select Flash Install CFW 5.50 GEN D-3 (first option) and press X
• At the end of the process, press X to restart your PSP
• Welcome to CFW 5.50 GEN D-3 !
• Oh, and if your PSP is a phat, System Setting will show "5.50 GEN-D (full)".
  A psp slim will show "5.50 GEN D-3"
