EML Generator: Write directly to the PS Vita memory card!
Our good friend Mr.gas and his french colleague TomTomdu80 (also known as Major Tom) just released yet another brilliant piece of software for the Playstation Vita.
Thanks to their EML file generator and a neat E-mail application trick, it will be possible to write files directly to the PS Vita’s memory card!
If you think we could already do this, then you are wrong. This allows you to write to the ux0:/ directory of the Playstation Vita, not the ePSP’s ms0:/ directory, which would be ux0:/pspemu/ by the way.
While it is nice to be able to write directly to the Vita’s memory card, one might ask oneself what this can be abused for? Well…
Let’s say you can unlink a memory card from a specific firmware, which enables you to swap memory card without being forced to format the memory card or update the PS Vita system software.
In theory this should also enable you to unlink the memory card from your PSN account. Those are just a few extras functions, to be honest.

The main part of the EML file generator was pretty much to enable you guys to install the PSM Dev for Unity application (necessary for Rejuvenate), which has been removed from the PSN stores, and is therefore unavailable… Or is it?!
Go ahead and check out the following video, that Mr.gas recorded for us:
As you can see, it is possible to simply install update files (and DRM-free applications) via the E-mail application in combination with the EML file generator. This should also be possible on firmwares that cannot use the PKG Installer (3.30+) anymore.

HI i am just curious
If we can install pkg by this way
Is it ok to update 3.52 and install it?
OR is 3.52 just block PSM exploit?
3.52 blocks PSM, do *NOT* update
well I am now in 3.18 🙂
First
FAIL
Does it work on PS TV?
And the noose tightens……..
So this means we can now write the modified whitelist file to the PS TV for improved Vita game capabilities?
I’m pretty sure anything to do with PS TV atm is low piority since that things is a complete and utter fail.
That would be a cool thing, than I get a cheap one.
Impossible.
and here i cant update passed 3.01
so would this allow me to move my backup vita games back onto my vita without using *** cma?
If the files are small enough to be sent through email then possibly but not too sure if you can do that with folders, right now i think we can only replace files.
Use qcma on offline mode and select manual firmware version 3.30 or whatever version below you have. I just used it to backup my games, while I’m on 3.51, and the original CMA was telling me to update the firmware.
I want to avoid having to use *** cma or any other variants like QCMA way of transferring files in general its slow as heck and buggy and I wish sony would have just allowed direct usb access even though I know why they didn’t
Hey, how do you make the QCMA work?? I have installed it, but each time I try to connect my Vita still tells me I need to update, and I’m on 3.51 too D=
Do you disabler WiFi and use the USB Cable? If the Vita ask for an update you must restart your Vita or it remember that it needs an update without checking it again. In the “Settings” of QCMA is an option for “Offline Mode” (first one under “Others”) that you must activate.
Use VitaUpdateBlocker and spoof your Vita version first. As ridiculous as it sounds I was able to use it that way, because QCMA only has up to 3.30 version.
Things just keep getting better everyday or other!
this is *** awesome
This sounds pretty great, honestly. Being able to install any file we want to the vita via an email exploit, as well as desync memory cards from a specific firmware? Awesome 😀
Good luck, devs!
Can we use this to update to a específicamente update? 3.51 have more memory avaible than 3.18… Also can i update the PSM app because i have the 1.00 thanks
Umm
you can already update to specific firmware
I used psvproxynet at /talk
Correct me if I’m wrong but did he not just install the psm dev tool in that video ? We didnt need to sign up ? 🙂
He installed the Unity app. The difference is that the standard PSM Dev app has DRM, while the Unity app doesn’t, so you still wouldn’t be able to install the standard dev app this way. (I think)
While thats correct, we dont need the standard dev app anymore. The Unity app can do what it can do and more. But we didnt know this before 2 days ago. So yes, we didnt need to sign up, but we only found out 2 days ago.
Do you think that we are now witnessing a PS VITA ‘s revolution ? or it is too early to say that ? GOOD JOB BY THE WAY
that time is never gonna come, but hopefully this new life in the scene at least squeezes a lil life from the vita before it fully dies a death
The update file is paused when I reboot the device… I can’t click on it… help?
same here -.- this “tutorial” sucks !
feel free to post a better one then u ungratful git!
you must start with rebuild database first…had this error..
for all of u having trouble open the test 2 eml and email yourself the two files inside …it worked for me
finally a promising hack! hope this leads to greatness!
So, how exactly do we use the mail generator app? What is the path we would need to set to it to install the PSM Unity app?
Whoops. Didn’t realize there was a completely separate download for the eml generator and for the Unity installer.
Fantastic work, mr.gas and TomTomdu80!
It’s amazing how many great news regarding native Vita stuff we have seen lately.
Yifan lu,i very much love you!!
can this copy just save files from memory card and not the whole application? if it can this would be really great
Are you saying we can finally have two accounts each with separate memory without the need to format!?
its possible
Just installed PSM Dev for Unity on 3.51 😀
how?
please provide step by step
How does one install PSM Dev for Unity? please explain in details.
Much appreciated for the response
Im impressed and this is coming from a vita engineer.
im impressed too and this is coming from the grand duke of york
i dont have any apps 2 update
what should i do ?
Have any of your games ever updated? If so, delete the update. (Google how to do it)
If you’ve never updated a game…well…go buy a game you know will need an update.
Do you have any retail cartridge game like Borderlands 2, Killzone etc? Just delete the installed app on the memory card and then you can re-download the update pkg. But backup your game first before you do that. Not sure if it will delete the game save.
I only have soul sacrifice demo and 2 free ps mobile on my vita
Can i just delete the update of psm dev then reinstall it ?
Or could i enter psn store with some kind of proxy cause my vita is ver 3.51
so what should we do if we dont have a game thats updatable?
If you have any cartridge games, you can back them up with QCMA, then completely delete them from the Vita. After reinstalling it, it will be at version 1.00, and offer an update. I’ve heard that physical games should be removed after the shutdown during the process. After everything is done, you can retrieve the save you backed up so you don’t lose your progress. If you don’t have a physical game, you can do the same with a digital game (assuming you’re on 3.51 and can use Vitaupdateblocker). Just back it up, delete it from the Vita, and re-download it. It will then offer an update.
“during the process” as in, during the process to install Dev app for Unity using the eml generator.
My Vienna Sausage turned into a full blown baby arm after this news thanks ZETTER!
Wow, just wow, I’m stunned by the speed of progress of this. Keep it up. BTW does this mean I can install toukiden on 3.51 and use vhbl?
Not possible, we can only replace files at this point, we cannot create directories and the files must be small enough to be sent through email.
Oh, thanks for clarifying.
I believe – we can
Is toukiden a DRM-free game?
“PS Vita System Update 3.53 change notes:
A severe issue has been found in the email application. Under no circumstances should you use this application, as it poses a serious risk to your PSN account. Email application has been removed as of System update 3.53, and we encourage you to update as soon as possible.”
… I wont be surprised if that actually happens.
PS Vita System Update 3.54 change notes.
Please don’t touch your Vita and just put it on a shelf or use it as a paperweight. Use rubber gloves and blindfold while doing so .
Does it work on PSVITA 3.50 ?
Yes.
Can any1 pls show us how to copy a psp legally backup (PC) to Vita MemCard n show the game bubble?
U can’t, no go away this is the wrong site for that
keeps saying “This File Is Not Compatible With Your System” when I go into Email… Anyone know what I’m missing here?
That was happening to me. It fixed after I began using Thunderbird to send the email. Make sure you forward the email to your address; don’t try to make it an attachment or anything.
Same here. I did the whole Rebuild Database, transferred the Unity Folder from my PS Vita/PSAVEDATA/****************/UNITY – 27MB
Now here is where it gets tricky: How do we do this, if most of us are on 3.51, and try to see which Game can be Updated without getting a Update nag from heck? Also, in my Mail, it only has the test2.eml File. No Image File types. I try to open the File, and it give the Above mentioned Error.
I used the Borderlands2 card and paused the update to 1.05. Used thunderbird to send the mail. Works perfektly on my 3.36 and 3.51 vitas.
It sounds like you sent the .eml as an attachment, rather than forwarding the .eml itself.
download thunderbird, configure your email on it, double click on the eml file and open it with thunderbird and foward the message to your email that is configured on vita
Only thing is, I dont have anything that can be Updated. PSM included. It is on 2.01
Ohhhh. You double-click on the .eml file.. now I see. Now… I see.
jesus ***! this means that I will be able to install the psm unity app in to my 3.51 vita?
I think the #1 first homebrew to come of all this should be a fw spoof. Sony has always killed the scenes exploits with updates lets keep this scene alive by never having to update again
Oh Yeah, I also hope so. I am holding back from downloading my PS Plus games from the store as I’m on 3.18. A spoof would enable to put all those on my Vita as well as test out PS4 Remoteplay, maybe.
You should be able transfer and run most psn+ games from a ps3 (assuming they arnt too recent or contain an update higher then 3.18)
Is there a reason why my Unity file is 15kb, while the file in the video is 27kb
I’ve heard this can happen if you use Open CMA rather than QCMA.
Interesting. And a little ironic too– I had just caught wind of that old article about mr.gas and tomtomdu80 dumping the vita memory cards. However, with that in mind I am not surprised it’s them that have released this new trick :). Great work guys.
Small error here:
This should also be possible on firmwares that cannot use the PKG Installer (3.30+) anymore.
So please tell me could I with this trick get PSM Dev for Unity onto my 3.18 Gladiator exploit VITA?
You could have already used the email PKG installer method for 3.18 a long time ago , didn’t you realize that ?
Can this be used to change the white list in pstv and play all the games that now doesnt allow the ps tv?
zett, get your website online again
You rock, guys ! Even though it’s just writing small files. First open door to the guts of the memory card !
Brace yourself. FW 3.53 is coming. I can smell it from that far.
In EM generator,what i must write in that 2 fields? Thanks
You’ve downloaded the wrong file for the Unity app installation. What you have is the .eml generator for general use. Look at the description of the video on this article for the correct download link.
