    First let me say i love this site XD. I tried upgrading my psp to 6.35 ofw n this is what comes up “The software of your PSP system is version 9.90. There is no need to update”
    ( I dont relli know much (hmnn mabye anything) about this type of stuff but 9.90 sounds a bit high so i went in the system settings n it says the systtem software is 5.50 prometheus. so can u help a dude out ?

      Follow the instructions on this page: Install 5.50 GEN-D3 but instead selecting “Flash install CFW 5.50 GEN-D3″, choose “Flash install 5.50 OFW”. It will revert you to the 5.50 OFW and by then you can start upgrading to 6.35 OFW.

      Did you extract it properly? Also, remember to turn off your PSP before installing. You need to be on OFW or you’ll brick your PSP.

        Thx bro^ ^ I already solve my problem…

    6.35 ofw for my psp 2000 and when i extracted it my psp cannot read the updater it says corrupted file -_-

    • sylv3rblade August 29, 2011 Reply

      You’re already on 6.35 OFW?

      In any case, the updater will say that if:
      1.) You have put the eboot.pbp file in the wrong directory
      2.) The file is actually corrupted.

        sorry for dumb questions im a newbie in this stuff but i just downloaded 6.60 in my psp -_- is it possible for me to play my games again?

  4. blablabla August 30, 2011 Reply

    hey its me again haha i downgraded my psp 2k 6.60 to 6.60 pro-b9 (model:2g) can i change from 6.60 pro-b9 to 6.35 hen or 6.31 hen? please help mee

    • sylv3rblade August 30, 2011 Reply

      Technically you haven’t downgraded since you’ve just installed 6.60 PRO-B9. To downgrade you need to go through the downgrade process detailed in this guide

    if we’re upgrading our PSP from the OFW to CFW, is it okay to leave the UMD inside? or I must take it out first before doing it?

    Thanks for the post. :)

    First of all, I have 6.31 OFW. I was able to use Prometheus Iso Loader with HEN but it won’t boot Monster Hunter Portable 3rd. I saw somewere I need 6.35 but will my save files still work for my other games? I don’t want to install 6.35 if it breaks my saves.

    • EliteAxe October 4, 2011 Reply

      Well I tried anyway and my saves work. I even was able to make Monster Hunter work! Thanks for all the tutorials on this website.

    • sylv3rblade November 3, 2011 Reply

      Please check if the file is in the proper directory (and that you have extracted the zip file)

    • sylv3rblade December 25, 2011 Reply

      Yep, I would recommend that you update to 6.35 so you can install 6.35 PRO-B10.

      Yes you can install the latest PRO LCFW build: 6.35 PRO-B10. Since you have 5.50 GEN-D3, your PSP is fully hackable and you can use the CIPL flasher to make the installation permanent.

    do you need to format your memory stick?

    • sylv3rblade February 16, 2012 Reply

      Nope

      • Kenshin February 17, 2012 Reply

        when you upgrade your psp does it need to be fully charged?

        • sylv3rblade February 17, 2012

          Not really but it’s recommended to charge to at least 75% when upgrading your firmware. That way if anything happens you won’t brick your PSP by having the battery discharge during the process.

          bago i upgrade kilangan ba uninstall yung ofw muna

        • Kenshin February 18, 2012

          cfw pla

        • sylv3rblade February 18, 2012

          Need na at least same OFW version sa LCFW na gusto mo iinstall (i.e. 6.35 OFW for 6.35 prob-10)

  16. Sena February 17, 2012 Reply

    is it permanent or temporary

    Sir! I’m actually afraid to upgrade my psp! I have 5.03 prometheus-4. How long will it take to upgrade and can I?

    • sylv3rblade March 28, 2012 Reply

      The upgrade, if you wish to push through, should take longer than 5 minutes of installation (upgrading to 6.35 then installing the latest pro build)

  18. Seishirou June 28, 2012 Reply

    I have psp 3002 with 5.03 prometheus FW, i forgot the rest of system details, and i didn’t bring my psp, so :)

    Ive read few forums and they said if my psp should safely updated by semi permanent CFW, and they recommend 6.35 pro or 6.39 pro… WHen i tried to update it, i couldnt found the OFW of it..Your link is blocked btw..could you tell me where to get OFW of 6.35 or 6.39??? :)

    PUT THE DAMN FILE BACK ON. OR LITERALLY REMOVE THE WEBPAGE, AS THIS LEADS TO DEAD ENDS.

    • sylv3rblade January 21, 2013 Reply

      I’m not sure why the 6.35 files we’re deleted but the other versions are still up.

      In anycase, I’ve reuploaded them to mediafire.
