Yoshiro’s XGEN Updater is a very useful tool that allows you to upgrade your hacked PSP (one with custom firmware installed) to the latest GEN CFW (which is currently 5.50 GEN-D) or if you dare, any official firmware version (just like Hellcat’s Recovery tool). If you’re asking how the XGEN updater will be of use to you when you’re already on 5.00 M33, it’ll save you the trouble of doing an incremental update of 5.00 M33 -> 5.50 GEN-A -> 5.50 GEN-B  -> 5.50 GEN-D.

What exactly does the XGEN Updater do?

• Flash Install CFW 5.50 GEN-D - installs custom firmware 5.50 GEN-D, everything will start automatically. This will bring you the latest firmware GEN, with all the benefits it provides (Playstation Store access, access to some of the latest games etc …)
• Flash Install 5.50 OFW - This option allows you to install the official firmware 5.50. Be careful, you lose all the benefits of a custom firmware if you do this update, and you will NOT go custom firmware if you do not have a kit Despertar del Cementerio or XGen Pandora
• Install any flash sony OFW- install any firmware official 3.XX to 5.XX, but at your own risk, because you lose all the benefits of a custom firmware and you will NOT go custom firmware if you do not have a kit Despertar del Cementerio XGen or Pandora.To use this option, copy the eboot file of any official firmware version you want to flash to the root of your memory stick and rename it to EBOOT.PBP.
• Inst all XGEN PANDORA - converts a kit despertar del cementerio V8 kit XGEN Pandora.If you install Updater XGen on a Memory Stick with Despertar del Cementerio V8, it will be converted to XGen Pandora. XGEN Pandora (you need a Pandora battery for this) will allow you to flash any PSP (except TA-v883 and PSP-3000) directly 5.50 GEN-D.

Important: DO NOT attempt to install this on PSP-3000 / PSP-2000 TA088v3. YOU WILL BRICK YOUR PSP IF YOU DO.

Important: Choosing any option from the XGen Updater menu (as shown above) will start flashing your PSP will start immediately. Read this guide fully before attempting to do anything with the XGEN Updater. Also, never remove the battery from your PSP while using the program (may brick if you take it off for a flash).

FAQ:

Why is there another 550.pbp there? Doesn’t the XGEN updater have one already?

Backup. If you encounter an error using the XGEN updater, replace the 550.pbp on your memory stick with the one included here.

What are the differences between XGen Updater and XGen Pandora?

The differences between these two utilities is that XGen Updater will directly install the custom firmware: 5.50 GEN-D on the console. XGen Pandora will only update the kit Despertar del Cementerio v8 to install it on 5.50 GEN-D when used (instead of 5.00 M33).
