Team GEN has just released the latest and greatest in the custom firmware world, 5.50 GEN-D. This update stabilizes the previously buggy 5.50 GEN-C release, and so far we haven’t heard any complaints from the community. The only known bug is a problem with speeding up the MS read speed, which is being worked on for a future release.

This release, like GEN-C, utilizes the new XGEN installer. If anybody has trouble with it, please feel free to leave a comment and we will do the best we can to help you out. Remember this is for PSP-1000 and PSP-2000 (V1 and V2) only. The 5.03 HEN-A will be updated soon for everyone else.

Official Changelog:

• All features previously in 5.50 GEN-B are now available.
• You can now run OFW 5.51+ games without having to patch the UMD or ISO.
• You can now run PSN demos requiring OFW 5.51+ without having to patch them.
• You can now connect to the PlayStation store by using the MediaGo software.
• You can use XGEN updater to install OFW 6.10 (and use PANDORA XGEN to return to 5.50 GEN-D).
• 480 x 272 videos play again.

Update: There seems to be some confusion in the community, relating to your PSP’s post-installation state. You must format flash1 after the update is complete, otherwise you will be operating under somebody else’s settings. You can do this by entering the recovery menu (hold R-Trigger on boot-up), selecting ‘Advanced’ and then selecting ‘Format flash1 and reset settings’.

Update 2: GEN D2 was released a few days ago (sorry for being late!). This update fixes the CFW check for Evangelion, fixes the WLAN TKIP bug in certain games, fixes video output with OFW 5.55+ games, and fixes the recovery menu problems some users were reporting with Pandora. You must be on 5.50 GEN-D before updating to GEN-D2.
