PSP 6.37 firmware now available – don’t update

To address the full security compromise of the PSP, Sony has issued a new firmware that aims to defeat the user mode exploits available in 6.35 Hen, 6.31 Hen and 6.20 TN-A Hen.

Important: If you have updated to 6.37 OFW, you can upgrade to 6.38 OFW to downgrade to a more useful firmware or upgrade to 6.39 OFW and install 6.35 Pro-B6.

So why a PSA to not update?  The new firmware simply patches out any exploits that we’ve been using and released to the public thus far without adding any useful functionality.  So yes, it’s a security update to stamp out homebrew (and more). The good news however, initial reports indicated that a similar exploit that most of the current non-signed hbl uses is also available on the 6.37 OFW.  Still to be on the safe side, don’t update.

The PSP Firmware 6.37 changelog reads:

This is a minor update that improves system software stability during use of some features.

Uh sure, Sony.  Sure.

      There’s a Homebrew loader working for 6.37 but it’s not confirmed if the Prometheus ISO loader is working (obviously, no one is willing to risk upgrading just to test if it works on 6.37 or not :(). Just wait a bit, I’ll push out a post regarding that.

        • sylv3rblade January 31, 2011

          A Pandora battery will brick your PSP if it’s unhackable (it only works for PSP phat’s and older PSP slims) as for hen, still no word.

      Unless your PSP is hackable, there currently is no way to play ISOs on 6.37 :(

    Hey, a friend of mine updated his PSP to 6.37 and he wants me to downgrade his PSP 1000 to 6.35 so it can be just like mine. Any idea of how to make a pandora battery without messing with the insides of the battery? I heard there is one program out there but I dunno how it works…

    • sylv3rblade April 18, 2011 Reply

      Creating a Pandora Battery requires a PSP with CFW installed. Since the PSP is 6.37, this isn’t possible. You can buy a Pandora Battery from any reputable online store however.

    at the 1st pace, i dont have any plan to update the psp, but thre is something wrong with it so i decided to update it. but i did not know dat 6.37 is not a user friendly version.

    i only want to know if there’s still games for 6.37? dat can be dloaded in net? thank u. :)

  16. jack105 May 22, 2011 Reply

    GUys you can still play ISO games on a v6.37. how? download a iso 2 eboot converter google it. but th elimit is 750 mb for now. that’s too sad right?

    • sylv3rblade May 22, 2011 Reply

      Yes that works but about 90% of the games we want to play exceed that limit :/

      • jack105 May 22, 2011 Reply

        Yeah man! It’s really sad can’t play great games like 3rd bday and dissidia duodecim. Hope you can create a HEN v6.37 at least so that we can use hellcats’ recovery flasher and flash it from there. Tried all possibilities even using hen from 6.35. still did not work. Guess just have to wait… real sad here man. I will keep visiting this page. that’s quick response bro… i appreciate that

        • sylv3rblade May 22, 2011

          So far there’s no public exploit to re-enable kernel access on 6.37 which is why there’s no downgrader (like Davee’s 6.35 to 6.20 Downgrader) or an ISO loader :/ I guess the last sliver of hope is if Total_Noob releases a Hen for 6.38. He released a video of a working HEN with kernel access on 6.38 OFW a few weeks back :/ Let’s hope he releases it soon.

  17. jack105 May 22, 2011 Reply

    Oh, I see…Yeah , my fingers are crossed right now man! Let’s hope he release it since many needs it badly to downgrade their psp’s. His help will be greatly appreciated and I can even ask one of my friends here to support Total_noob, and ask to donate at least minimum of $10.00 each to help him. If he release that as early as possible, i will donate some of my bucks to help him encouraged and help many out there…
