Update: It seems TomTomdu80 and Mr.Gas have ways to solve the issue of installing PSM Dev for Unity on firmwares 3.20 and above (including 3.51). Scroll down for details, and stay tuned for more!

Yesterday, YifanLu announced that the PSM Unity Dev Assistant is also vulnerable to the Rejuvenate hack. The PSM Unity Dev Assistant is a separate app from the PSM Dev assistant. The PSM Dev Assistant is the one people had been advised to download initially for the rejuvenate hack.

Additionally, the PSM Unity app is more promising than the PSM Dev app, because it does not require a usb connection (the connection can happen over wifi), which means it could be compatible with the PS TV. To make things even better, that app apparently does not have any DRM, meaning it could be installed without a PSM Developer license (reminder: the PSM Developer license is *not* the same thing as the publisher’s license).

The problem is, that PSM Unity Dev assistant is gone from the PSN store. I have asked around, and I am not getting a clear answer to the simple question: “can people on firmware 3.51 Download and install the PSM Unity Dev assistant today?”.

I opened a thread on the /talk forums to gather answers to this question. you can check it here. For now, my understanding is that it is not possible for people on 3.51 to get this app now. If you have it installed on your PS Vita or PSTV, good for you, you’ll probably be able to enjoy some of the scene’s offerings in the weeks to come. If not, stay tuned while people look for a solution (and you should look for one too! Just because the situation isn’t clear doesn’t mean solutions don’t exist.)

Bottom line is, if you know how to download and install the PSM Unity app today on a 3.51 Vita, we have thousands of users here who would love you to share your steps 🙂

On a side note, I received a couple complaints from people, blaming me personally for the confusion that was generated around this release, and asking for apologies. I want to emphasize first that I did not drive this release, I am just reporting the news as we get them from the hackers. Secondly, it was discovered only yesterday by YifanLu that the PSM Unity Dev assistant was also vulnerable, and I posted about it within minutes of Yifan’s post. I assume that the discovery was triggered by the fact that Sony removed both apps from their store, implying that they both had a vulnerability. It’s not like hackers or myself knew before yesterday that the exploit was there as well.

We’re trying our best here to be as clear as possible on the steps to take to get access to the hacks. But at the end of the day, we’re getting the same information you’d get from the hackers themselves, their blogs and twitter accounts. If you feel the information we delivered was less clear than what people like Yifanlu have explained, then fire at will.

Update: tomTomDu80 announced on Twitter that him and Mr. Gas have solutions to this problem, and they will publish these solutions sometime soon. Stay tuned!

. @frtomtomdu80 The upcoming release will more likely allow you to do so.

For what it’s worth, I do not have the PSM Dev for Unity app installed on my PS Vita either. Just sayin’… it sounds like a safe course of action for the future is to download every single free app you can find on the psn store, just in case.
