Install PSP Custom Firmware 5.50 GEN-A

While everyone’s still waiting for a Dark Alex release his version of 5.50 custom firmware, PSP GEN has managed to release their 5.50 GEN-A Custom Firmware. Do note that the earlier 5.03 GEN-A via ChickHEN hack release is for PSP-3000 / PSP-2000 TA088v3. This version of 5.50 GEN-A is for PSP-1000 / non-TA088v3 PSP-2000’s.

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

Update: If you want an easy way to upgrade to 5.50 GEN-A and it’s successive updates ( 5.50 GEN-A -> 5.50 GEN-B -> 5.50 GEN-B2 -> 5.50 GEN-D ), you may want to look at Yoshiro’s XGen Updater.


How to install 5.50 GEN-A CFW on your PSP:

  • Extract the 5.50 GEN-A files to your computer.
  • Copy the PSP folder to your PSP’s memory stick. (Yes, just drag the whole folder there)
  • Run 5.50 UPDATE from under Game on your PSP’s XMB
  • After all process is complete, press X. Your PSP will reboot.
  • Congratulations, you’ve just installed 5.50 GEN-A

Important Notes:

What do I get with Custom firmware 5.50GEN-A?

  • All functions of the official 5.50 firmware
    • The [Information Board] has been added under [PlayStation Network]
    • PS3 owners are already familiar with this feature.  It displays news and updates from SCEE in the upper right corner of the screen.  You can now obtain information about the games ahead of the new content available on the Playstation Store, and other news from your PSP even if you are connected to WiFi.

    • Support for Internet security service provided by Trend Micro has been added to [Internet Browser]
    • End Micro Web Security: use technology to block access to malicious sites that can steal personal information and confidential –
      Trend Micro Kid’s Safety: You can block access to websites with inappropriate content.

    • An icon for built-in Internet Search has been added to the menu bar of your browser
    • Instead of having to point your browser to Google then search, you can do your searches directly on your XMB.

    • Option to search for the game title on Google.
    • By selecting the icon of the game and then pressing triangle and selecting running Internet Search, you get to search for sites using the name of the game.

    • It is now possible to see an additional level of hierarchy under [Photo] [Music] and [Video]
  • Launch of UMDs to ISOs to CSOs and demos require firmware 5.02 or below
  • Launch homebrews
  • Launch of PS1 games (converted to PSP)
  • Access to Recovery mode (adjusts the processor speed of the PSP, FLASH access, use plug-ins etc.).

Hat off to PSP GEN  for 5.50 GEN-A.

      check the CFW compatibility guide to see what PSP-2000 motherboard that you have.

      If you have a non-TA088v3 PSP-2000, then you just have to downgrade via Magic Memory Stick, if you have a TA088v3 PSP-2000 then that’s a no.

      Try playing those videos on your PC to see if they work. Something tells me that the videos didn’t download properly.

        I tried them on the computer and they work fine and they play fine on my ps3. I still can’t get to the playstation store. It keeps telling me that I have to update my firmware, which of course I don’t want to do. Any more suggestions. Will the cfw 5.50 gen-a fix this?

        • atmaxplorer sylv3rblade June 18, 2009

          In anycase, yes, 5.50 Gen-A will fix your PS Store problems.

    • atmaxplorer sylv3rblade June 18, 2009 Reply

      5.50 Gen-A loads pretty much the same as previous custom firmwares. However, it will let you run games that need a 5.50 firmware version.

    I have a qns to ask Let’s say i installed the 5.50 GEN CFW. Can i install back the M33 CFW if Dark Alex comes out the new one? Is the procedure the same as how i install CFW M33 into my psp? Download pbp & CFW file. rename the pbp file and throw both into the update folder. Then update

    • atmaxplorer sylv3rblade June 20, 2009 Reply

      Yes, you can go to DA’s CFW. You can just flash your PSP to it’s original firmware then installing CFW and upgrade all the way to DA’s latest version.

      As for the steps, everything is just a single file 😀

    • atmaxplorer sylv3rblade June 21, 2009 Reply

      Please read the guide again. At the very top, you can see it’s pointing your to custom firmware 5.03 gen-a which is for PSP 3000s. However seeing as you already have version 5.50 for your firmware, then you can’t run custom firmware. At least not yet.

    I have a psp PHAT that has sony’s 5.51 is there anything that i can do to get custom firmware. If so how? Also I don’t have access to an already modified psp and the computer I have runs windows 98 so that limits programs that i can run. Please don’t bash me I know my computer sucks. Any help is welcome, and I need it.

  21. general_jurgs Jurgs June 28, 2009 Reply

    I also have a psp SLIM but I am unsure which motherboard it is. The serial code starts in HU0 and the guide mentioned HU2 not sure if this is the same or not. But the firmware on that one is sony’s 3.80. Combine that with my previous post and you have my question. Can I run custom firmware on either of these systems. Oh and the slim has no screen so i’d be doing anything blind. But my brother has a working slim with the same specs as mine but his serial begins with HU1. Any suggestions?

    mr. sylv3rblade.. i already installed a popsloader that is working fine in a 5.00 m33 – fact i already using it..

    my first question is can i update to 5.50 gen – A if my current firmware is 5.00 m33-6?

    and if i can i have to update my popsloader??

    note:on a site ( i’ve read that there is a popsloader for 5.50 gen-a…do i have to install this if i can update to 5.50gen-a? or my current popsloader will work fine to 5.50gen-a…

    • atmaxplorer sylv3rblade July 1, 2009 Reply

      The rationale is that when you upgrade your firmware, you also need to upgrade your POPSLoader to prevent any conflicts.

    i update my cfw to 5.50 gen-a but in my opinion it still needs to improve..there are some bugs that i noticed so i decided to switch back again to DA’s M33 cfw..

    my question is how can i do that?
    is it possible to switch directly from 5.50 GEN-A to 5.00 M33(the old method DL 5.00pbp then put in update folder blah blah blah..)is that it?

    Hi, I’m not familiar w/ PSP at all, just trying to make my 7yr-old’s PSP-1007 (w/ 3.52 M33-2) to play Transformers-Revenge of the Fallen. It needs 5.50, but then I got the “DADADADA…” msg while trying to update from the UMD. So after a few hrs of browsing the net I thought my best option was to install CFW 5.50. Now I got “This program requires 3.53 M33-2 or higher”, so I’m stuck again. Thanks for any help!

    • atmaxplorer sylv3rblade August 17, 2009 Reply

      DA has not yet expressed interest in updating his latest release which is why we still don’t see a 5.50 M33.

      If you see a 5.50 M33 installer floating around somewhere don’t install it. It’s a fake and will likely brick your PSP.

    If he has a 4 GB sandisk MS (Probably does) then he should use a smaller MS, like 2 GB. The same thing happened to my bro and I let him use my 2 GB sandisk memstick to upgrade and it worked fine.

      If you’re not comfortable jumping to 5.50, you can install a 5.00 M33 first, since it’s more stable.

    • atmaxplorer sylv3rblade January 31, 2010 Reply

      It’s possible to upgrade to any 5.50 GEN cfw directly but it’s not recommended due to the number of people experiencing “hangs” during installation (and seriously, you don’t want your PSP to hang during any CFW installation).
      For clarity GEN-B, GEN-C, GEN-D is that they are patches for the original 5.50 GEN-A cfw. 5.50 GEN-D2 and 5.50 GEN-D3 are patches of GEN-D. To put it simply, they’re updates to the 5.50 GEN CFW.
      If you want to upgrade your current PSP version please install 5.00 M33 first then install 5.50 GEN-D3.

          Then you’re lucky this failed to install. Please read the warnings next time.

          Use this firmware version instead: 5.03 GEN-C

      Be sure to check out the Dummy’s guide to Custom Firmware so you can educate yourself with what’s what.

      As for your PSP, you can upgrade it incrementally (since upgrading to 5.00 OFW in one go is not recommended) until you reach an OFW that is the minimum for custom firmware, in this case, 3.80 OFW

      Since you’re looking for a way to install CFW without a Pandora Battery: use this guide.
      Do note that you need to upgrade to 5.03 OFW for this

    Hey i have a phat psp ver. 5.03 OFw and i want to hack it to gen- A will it brick or not?

      You have a Phat so you can install pretty much an CFW on it. The question however is are you already on CFW? If not, follow this guide to convert your PSP to CFW
