Warning: 5.50 GEN-B CFW is for PSP-1000 and PSP-2000 ONLY. If you try this on PSP-3000 you will BRICK. For PSP-3000 use THIS.
You MUST have some form of Custom Firmware in order to install 5.50 GEN-B Custom Firmware.
The main reason you may want this is because it requires 5.50 to be able to use the Playstation Store. I had to install it because I wanted more Rock Band music, but it's a good substitution since this Custom Firmware was made by rebuilding M33. Anyway here is the changelog with some new features:
- The bug that prevented disabling the VSH Menu has been resolved.
- The select button can either start the Recovery (Recovery in VSH), the VSH Menu (default) or do nothing at all (for those who use the remote play between PSP and PS3)
- Updated network off M33
- Evangelion Jo can be launched.
- Pandorisation options are available in the VSH menu and Recovery
- Option Flash1 Format: adding a check that prevents the Flash1 format if it is in the VSH.
- 3 new functions in the VSH Menu
- Shutdown device (turn off)
- Make Normal Battery (Replace the battery in standard mode)
- Make Pandora Battery (pandorise battery)
