6.38 Downgrader by some1

Update: this has been confirmed by many trusted sources to be real and working. We also confirmed that this entry is accepted in the Genesis competition

I usually test those things before blogging about it, but this is huge news, some1 is a respected dev, people have reported success with it, and I’m stuck at work with my pspgo without the stupid proprietary cable. So I can’t test it right now, but I’ll report it anyways.

Developer some1, who once ported HBL to the latest firmwares, released a downgrader for 6.38. Does it mean he found a new Kernel exploit? The readme is a bit unclear, mentioning a VSH exploit by TiPi and Nymphaea, so we’re probably between a user mode exploit and a  kernel exploit here, which might be good enough for a downgrade. Some1 confirmed that he found a Kernel exploit. He mentions TiPi and Nymphaea’s VSH exploit because it indirectly taught him a lot, but what he uses for this downgrader is his own Kernel exploit.

This tool allows you to downgrade a 6.38 OFW PSP back to 6.20, to then allow you to install a Hen such as TN Hen or Pro 6.35

This is an entry for the PSP Genesis competition., although we haven’t reviewed it yet.

Credits from the author:

To Davee for making the original 6.35/6.31 downgrader
To ultimakillz and skyend for being my mentors when I first entered the scene.
To n00b81 for teaching me a lot of things.
To Davee, Freddy, TheLemonMan, Hellcat, and Draan for answering any question’s I’ve had.
To TiPi and Nymphaea for allowing me to work on their VSH sploit, which gained me alot of knowledge and experience.
To Npt for hosting such an awesome competition!
And to many others that I’m probably forgetting.

This has been confirmed to work by many testers, and you should have no issue running it. If your PSP is not compatible with this downgrade, the program will let you know, and won’t let you harm your PSP, but use at your own risk

Some1 also confirmed that he is working on a solution for unsupported models (psp 3000 07g/09g) and that he needs beta testers

    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.

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

      It will only downgrade to 6.20. If you have a 7g/9g module you’ll have to wait to see if some1 will port it to downgrade to 6.35

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

    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)–

    DOWNLOAD OFW: Search 6.20 OFW from GOOGE SEARCH
    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.

    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

    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?

    Reply

    1. Jurian’s avatar

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