[OPEN] Ways for people on 3.51 to install PSM Unity?

[wololo]

Yifan Lu announced yesterday that the PSM Unity Assistant is exploitable as well, and will be more convenient than the other PSM Assistant app.
Now, I'm going to guess that not so many people have the PSM Unity Assistant installed at this point.
There are ways for people on 3.18 to get it and install it, but I am not sure for 3.51.
The pkg is apparently gone from the store, so it's not only an issue of using a proxy, but if people have a way, I'd like them to post it here (with steps described as clearly as possible, please)

If you have a solution, feel free to write a tutorial and post it in the tutorial contest! ( viewtopic.php?f=65&t=42986 )

Thanks in advance!

Possibly use the same proxy method except host the PKG File using a localhost to download the file? Or I can upload the app then it should transfer using content manager to any firmware without issue as its DRM Free

Can confirm this doesn't work but i think the only way for this to work with using only a ps vita would be to use the vita web browser and redirect it to the psn store skipping the psm page and linking directly to the download, but i don't think anyone knows how to get the download directly, another workaround might be to use a wi-fi traffic sniffer, modify and re-inject traffic to make the vita think a demo download or something is the psm .pkg not sure if it will work tho if the licenses don't match.

Yifan lu seems to have a way : http://yifan.lu/2015/06/24/on-the-futur ... mment-6016

EDIT : @frdutomtom80 teased for a way

[wololo]

Thanks motezazer! Indeed, it seems TomTomDu80 has a solution in the works:

I made a little tutorial summarizing the different available (and upcoming) ways to install psm unity :

@smithsf0x I didn't ask for more questions, I suggested answers.

The way I used to install it is having a vita on or below 3.20 and just using package installer to install it to that device, back it up using qcma and restore it onto my 3.50 vita. This way works but it also unfortunately requires the use of a second device on a lower firmware. I don't see why this wouldn't still work but when I got the app installed it was right around the time yifan lu made the announcement to register for a PSM Dev license before the service is terminated. I saw the package file online and installed it for the heck of it.

The Ps TV is cheap if you get it on sale, most still come with 3.20 so people can use that to install it if they can't wait..

to install it from 3.51 there are 2 ways:

Method 1:
Have another ps vita with the pkg, so just make a backup via cma and restore it on the 3.51 vita

Method 2:
You need a ps3. Use charles: set the proxy on the ps3, then select a vita demo game from the store and download it and then press the background button, go back to the XMB and pause it. on charles map the pkg with the one you can find on the vita dev wiki (direct dl), then just resume the dl and it will download your pkg (with the name of the pkg you was downloading). then just use CMA to install it on your psp2. this should work since the base pkg is 'free' and do not have the DRM as the other one.

So ever since I first created libvitamtp, I wanted to include PS3 support (aka, pretend your PC is a PS3). That way you can perform PSN activations and PKG installing directly from opencma/qcma masquerading as a ps3. Unfortunately, I never had the time to do so because I've been busy working on other things (like vitadefiler). If someone does it though (either by sniffing the USB externally or by reversing the modules on the PS3), they can access the package installer built into the CMA app and install any packages the Package Installer app can.

Another idea is to find an webkit exploit on 3.51. Shouldn't be too bad since there's been a couple of new webkit exploits that may be possible to port to the vita. Using webkit to launch package installer has already been done on other fw versions.

Since it'll be ways off before rejuvenate is ported to psm unity (I myself won't have time to work on it for a couple of months at least), people can start looking into these methods in parallel. That is why I made the announcement so early on.
