    For some reason my psp will randomly turn off and on, no matter if my memory card is in or not. i tried different batteries and still the same thing, removed the battery and just used the ac adapter and still nothing…. what can i do to fix my psp 1000 running Cfw 5.00 M33?

    • sylv3rblade March 26, 2010 Reply

      It could be a bad flash or a hardware problem :( Have a technician check it up.

    I just installed GEN_A_Update 5.50 on my psp 1000 japanese. I am now trying to install gen_b 5.50 but am always getting data corrupt message. What should i do? By the way the psp had 5.02 before update

    • sylv3rblade April 12, 2010 Reply

      The 5.50 GEN-B installation files that you have downloaded is probably corrupted. Try redownloading again.

        Pls give me your good link for 5.5 gen b

    I can’t seem to get my Pandora + magic to downgrade the fat psp …..it keeps going from 68-99 looping …

    I have already installed Custom Firmware 5.50 GEN-3D in my 1000 PSP, but i have to format my memory card due to virus problem. Even i didn’t back up my previous file. Do I need to re install the firmware again??
    Right now i download the 5.00 M33 CFW and installed as you have written. But when ever i tried to run that file the message pop up saying that “This game cannot be started. The data is corrupted.” I had download the file twice and tried but still i m getting the same message. Please help me. Right now I have System Software Version 5.50 in my system information. Thank You.

    • sylv3rblade April 26, 2010 Reply

      How did you install 5.50 GEN-D3 in the first place? By using ChickHen? Either way, you’ll be needing a Pandora Battery to reinstall CFW.
      The reason you can’t install 5.00 M33 on your PSP is that it’s a lower version (5.00 is lower than 5.50) and you can’t downgrade a PSP without a pandora battery.

  12. amendra April 27, 2010 Reply

    Initially one of my friend had did that. But now i want to do by myself. So, I downloaded 5.50 GEN-D3 and try to reinstall in my PSP. But mistakenly I have installed “Flash Install OFW 5.50″. After that again i tried to run the 5.50 GEN-D3 then the message pop up saying that his game cannot be started. The data is corrupted.
    Right now i have got 5.50 Version System Software in my PSP. But I need to reinstall 5.50 GEN-D3. Is this possible without Pandora Battery? Please help me.

    Do I need to reinstall the Custom Firmware in my PSP in every format of my memory card??

    • sylv3rblade April 27, 2010 Reply

      Well you basically installed the official firmware so the only way to get past that is to downgrade using a Pandora battery. Using a Pandora Battery is the ONLY way to install CFW on a PSP once it exceeds 5.03 OFW :( . Also, no, you don’t need to reinstall your cfw when you’re just going to reformat your memory stick.

      • amendra April 27, 2010 Reply

        Now what m i supposed to do? What will be the best solution for me so that again i can play my PSP with memory card. Waiting for your reply. Thank You.

          Try upgrading to 4.01 M33 before installing the 5.00 M33 update

  17. iCe May 25, 2010 Reply

    guys, a little help please..? i’m getting error message everytime i run the 5.00 update under Game. it says:

    “This game cannot be started. The data is corrupted.”

    i downloaded everything (5.00 M33 & 500.PBP) and followed all those instructions above, but everytime i run the 5.00 updater, i’m getting the same error message..

    i got the installers from the links provided above so i’m pretty sure it’s not the files i downloaded.. i’ve done uninstalling and reinstalling everything for about 10x now, but to no avail..

    i have a Pandora PSP Slim 2006, current FW is 5.51 (before it was at 4.31 i think). i have no idea what happened.. please guys, i need your help..

    • sylv3rblade May 25, 2010 Reply

      You have updated to the official firmware 5.51, you need a Pandora battery to downgrade and install CFW.

  18. Dono June 6, 2010 Reply

    Is this too long to unpack? I followed all the instructions above and started the update but it takes too long for it to unpack. what do you think is the problem?

    3.90M33 – 5.00 M33

    • sylv3rblade June 6, 2010 Reply

      Shouldn’t take more than 5 minutes for the whole process. Looks like something went wrong.

  19. Darkelemrnt June 7, 2010 Reply

    umm, I did end up downloading the official firmware :( That’s what I had asked. So does this mean I have to make another magic memory stick and borrow my buddy’s Pandora battery in order to download the custom firmware?

    I want to go back to OFW. How would I go about doing this? I am currently on Gen-d.

      when I try I get error reading 500.pbp at root. I have tried for different time, each with the eboot file from a different site, (thinking that I got a corrupt version), no luck.

    • sylv3rblade June 10, 2010 Reply

      You need a Pandora Battery to downgrade as your PSP won’t allow you to install an update that’s lower in version that your current firmware.

  21. NubPerson June 15, 2010 Reply

    Errrmm…. Why does it say that 500PBP is a incorrect file when i run the thing?

    • Darkelemrnt June 15, 2010 Reply

      do u have a pandora battery?

    • Anthony August 5, 2010 Reply

      Dude If you follow the directions nothing goes wrong. It says incorrect file maybe because you put the cfw and changed it to 500.pbp you have to change the FW to 500.pbp and leave the cfw as eboot.pbp

      Yes, you can upgrade to this firmware directly. To be able to play Peace Walker though, you need to install the prometheus module for this firmware.

    Re-scratch everything. Now, I’ve been able to download official Firmware 5.00 by creating an update folder and not re-naming the EBOOT file (can u tell i skipped one of the steps, oops). So do I need to your directions on how to convert my psp to coustom firmware, or is the custom firmware already downloaded, it just didnt copy the name correctly?

  54. sylv3rblade June 7, 2010 Reply

    Well you need the instructions above to upgrade your existing firmware to 5.00 M33. Otherwise you might end up installing the official firmware and end up in a whole lot of trouble :(
