    Wow, I hope this works. I had to upgrade for FFIV:CC, and hope to be able to go back to 6.20 some day.

    Well,I wont try it since I got TN-D 6.20 on my 2nd PSP,there is no need.

  3. brandt says:

    Does anyone know if it’s possible to use this to downgrade to 6.30 instead? Newer PSPs don’t allow anything older.

    IT WORK!! MANY THANKS >my psp slim 200x>6.38ofw>6.20ofw>6.35ofw>6.35pro-b5 😀

    This a very simple app, just put the official 6.20 updater in (ms0/ef0 accordingly)PSP/GAME/UPDATE, and run the downgrader, this will reboot into the 6.20 “update”, and allow you to downgrader to 6.20. Has been tested on 1k, 2k, 3k, and Go (doesn’t support 07g or 09g)

    IMPORTANT:DOWNLOAD 6.20 OFW first and put to PSP/GAME/(HERE) like above and then Run the 6.38 Downgrader –(MULTIPIE CHECK THE 6.20 OFW ON UR PSP AND MAKE SURE THAT 6.20 OFW FILE NOT CORRUPT)–

    Good luck !!

    Update on my last comment:
    Tested and used with success on a PSP Slim 2004, 02g TA-085v2 from 6.35 to 6.20.

    @GOKU: Seems to be signed, it starts for me using OFW 6.20 on my TA-085v2 PSP Slim.

  17. Jose_luis070 says:

    I tried it and it works because I tested it on a psp 1001 and worked as proved in pspgo tell them whether they will walk

  18. The downgrader works by allowing the starting of ANY SCEA Updater below your current version. I don’t think the issue is going below a certain version, but rather an issue with 07g-09g PSPs themselves, because wouldn’t you just be able to use this with 6.35 Update instead of 6.20 instead?

    • Jurian says:

      Not if the downgrader only looks for the 6.20 update and not any others, then it will only work with 6.20.
