Install PSP Custom Firmware 5.50 GEN-C

PSPGen and GENyUS has just released 5.50 GEN-C. If you’re thinking *yawn*, not another incremental update then you’re sadly mistaken as 5.50 GEN-C will let you play 5.55 and 6.00 games straight from the ISO :D. Sounds like quite a deal doesn’t it?

No more decrypting, no more patching and no more rebuilding. Well that is the only case IF you have a HACKABLE PSP (Is my PSP hackable?). For PSP-3000 / PSP-2000 TA088v3, it’s still the Game Decrypter method for you.

Important: GEN-C is still buggy and is causing a lot of problems. I recommend installing 5.50 GEN-D3 instead.

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


  • Any PSP with custom firmware installed 3.71 M33 or above. 5.00 M33-6 is the best bet for the XGEN Updater to work.
  • PSP battery that’s at least 78% full
  • Download: XGen Updater
  • Disable ALL plugins.
  • Back up your save files (so that if they get corrupted, you still have backups)

How to install 5.50 GEN-C using XGen Updater

  • Connect your PSP to your computer
  • Extract the XGen Updater to your PC
  • Copy the PSP folder and the 550.pbp file to the root of your memory stick
  • On your XMB, go to Game > Memory Stick to start XGen Updater
  • Select Flash install CFW 5.50 GEN-C
  • After all process is complete, press X. Your PSP will reboot.
  • Congratulations, you’ve just installed 5.50 GEN-C

Update: PSPGen and Yoshiro’s explaination for 5.50 GEN-C’s issues: (Translated from French)

First we present our apologies for this release that posed more problems than we expected. To be very frank, in our tests made in the same manner as other times, we had satisfactory results, but several factors intervened between the announcement of the online one. We will try to explain the why of how this release cursed.

Firstly, the original version that was being posted was well prepared for this announcement and we had given 24 hours of additional testing to verify that everything worked well. This first release does not launch the protected games but all games 5.55 +. In the process, Yoshihiro out how to counter the protections we have decided to announce and release in the edit function. So this is where we fished for if everything worked in our tests, it is found that certain protections of our CFW have come to panic under certain conditions and also depending on the model of PSP. Moreover, to avoid (too much) delay the release, we dropped the baby without giving her a test period of time. Accept our apologies for this.

In our defense, there are several types of errors, some of which we are not attributable to:

* You have a black screen by launching the updater
You are in Custom Firmware 5.50GEN-B and not in B2. It was enough to qse B2 therefore to resolve the concern.
* You have a semi brick ( “I have the clock …”)
You had left a personalized theme and therefore it was enough to format the flash1 via Recovery menu. Do not have a personal theme during a flash console is part of b and ba and we had forgot to report it. Nothing serious, however, because the Recovery remained accessible and / or restart without his MS usually enough to break the deadlock.
* You bricked your console
The installer of 5.50GEN has no CFW our bug and can not be directly responsible for that. Everything is working 200%, you can be sure Clearly, note that if you have bricked is probably due to a failure of your nand that would have occurred at any other attempt to flash your console including an official.

Note that GENyUS and Yoshihiro currently working to ensure that these mistakes are forgotten as quickly as possible and we will post the Custom Firmware 5.50GEN-D when everything will be validated and verified. A priori, this should not be long and, again, be assured that we are sorry for any panic.

If you still want to proceed to installing 5.50 GEN-C, continue reading below.

I’ve also updated the post for the XGEN Updater with this information.
