    i see what about 3.18 FW questions and what about 3.52 FW questions but im on 3.15 FW? will this work on it?

  2. Naughticon says:

    uhm.. i’m on 3.18 and installed PSM dev for unity, but needs to be updated.. may i know how to update it? it asks me to update my system software before i can do the update for PSM dev for unity.. if i do update my system software i’ll be on 3.52 and i can’t use this PSM dev right? what do i have to do? sorry.. really noob.. thanks in advance..

  3. Kevin says:

    Confused on step 3, so do you just open to email, then forward it to yours own personal email address? I keep trying that with my gmail account but its not showing as image attachements.

  4. Kevin says:

    On step 3, do I forward it to my personal email? tried that but the two attachments aren’t image files.

    I finally got it installed after so many tries.

  7. Tinger says:

    Stuck at Step 5 with QCMA. Am I Doing Something wrong? its the could not connect to the PC problem.

  8. oeron says:

    Need help, i’m on 3.51 and when i connect to content manager i tells me to update. I installed open cma but it still wants me to update. So i can’t go further then step 5. Appreciate any help, thanks.

    • ioruel says:

      -enable airplane mode and disable the wifi then turn off your vita
      -turn it on again
      -connect it to ocma/ qcma
      if that doesn’t work rebuild databaseand try again … remember you need to restart your vita with wifi turned off

      • Oeron says:

        Thanks buddy, I did everything like you said but it still asks me to update. Isn’t there an alternative way to transfer those files without content manager? Or is there anything else I should give a try?

        • emusonpsvita says:

          Same here. Keep trying to load up content manager to copy the package but content manager on the vita keeps saying to update. On firmware 3.51. Been rebuilding the database and airplane mode, nada.

          • Oeron says:

            I fixed that. You have to use QCMA http://wololo.net/downloads/index.php/download/8241 , i managed to copy all files to my vita. Just keep PC and Vita both offline, i tried a couple of times but then it worked.
            Solved this problem but stuck in the next step. I don’t have a game who requires update, and i can’t download any from PSN store. I use vita update blocker 1.2 but that doesn’t help either. I’m asking those who are on 3.51; how did you managed to access PSN store without updating?

      • Tinger says:

        thanks for the reply guys. im gonna try until my vita yields and allows me to copy. yeah and finally get stuck on that update step.

  9. dds says:

    i have ark 2 with paptapon2 already but i dont have any game who need update is that problem
    hat to do

    • sasdas says:

      what fw is your vita on?

    • Oeron says:

      I solved this update problem minutes ago. If you ain’t got nothing to update, just go to system settings, PSM runtime and click update to do that update trick. The rest goes on with the email step and etc.

      • tag says:

        Hey, know this is an old post but im trying this process right now. On 3.50 and cant connect to PSN to get any updates for apps without updating my FW… i dont have PSM installed. Trying to install UNITY for the first time. Any way i can do this?

  10. Oeron says:

    Yow guys, i really really need help. I’d no game that requires an update, so i transfered the game to my PC, deleted the patch file (also the whole game from vita), then transfered the game back to vita. Now when i hit refresh on the game page no update icon appears, i’d that for 3 different games but that doesn’t help.

    Then i tried the same with facebook app and a f…ng update icon appeared, but when i click on that f…ng update icon it saz ‘the latest version of this application ia already installed’. I’m rally *** off, pleaaaase someone help me 🙁

    I also tried vita update blocker but that doesn’t help either.

  11. Tom says:

    Hi did it on 3.52 got the magic message from Mr. Gas but no app bubble has appeared. I’m guessing people below 3.52 would have an app bubble so what I’m really saying is that following the instructions does work.

  12. Rich says:

    I don’t get it. I have 3.51, I put UNITY in the PSSAVEDATA ########### folder, and it will NOT appear at all. Nothing I do seems to work.

  13. adnen says:

    I did all the steps but I coudn’t find the PSM unity app on my ps vita ; and I can’t tap on the message showing failed update

  14. R.O.C.K. says:

    I’m trying to install the Unity App on my 3.01 Vita, but I’m being out of luck. As my Vita has a faulty USB port I can only rely on wi-fi, but when I try to use the Package Installer it disconnects from the QCMA (as I can see, it simply disconnects when I’m in livearea). Does anyone knows an alternative to it?

  15. help me plz says:

    i followed every single step.. got the message from mr gas.. but no unity app bubble 🙁
    and i tried following the steps but it’s the same.. any guidance?

  16. youmakeit says:

    Is this hack worth it over vhdl ? i have a ps vita with vhdl on fw 3.18, should i switch to this?

  17. Chilly says:

    Could someone send the mr gas email to this gmail, used only for vita homebrew, so I can install it.

  18. progamer1515 says:

    I’m having a problem with step 6 (Rebuild device database), for some reason, the progress bar keeps stopping in the middle. I have firmware 3.36

  19. progamer1515 says:

    Never mind, I just have a lot of stuff on my memory-card that it needs to reindex. It has successfully finished the database rebuild. Now onto step 7!

  20. 11770 says:

    whenever i try to connect to qcma or even open cma it tells me could not connect to the pc when using usb mode, but if i try wireless mode it tells me i need to update, first time using qcma, have been using ocma till version 3.18 i haven’t connected my vita to the pc since i updated to 3.51, whats wrong with my setup?

  21. 11770 says:

    should it say could not install.(C2-13275-8) the only option it gives me says cancel?

  22. almando douglas says:

    i’m having the same problem, help plz

  23. Mike Diaz says:

    I’m having a very difficult time with this. I have 3.51, and I just cannot get past step 5. At first, It would tell me to do a system update when trying to use content manager. I downloaded and installed QCMA, and I am still unable to copy it. I go into content manager on my vita, and now it just tells me “Could not connect to the PC”. I tried doing this with wifi off, and rebooting in airplane mode. How the heck do you get this to work?

    • Hackems says:

      I was stuck here as well this is what I did, I reinstalled qcma it has to reregister your device which is why i did that tell me if that works or not.

  24. Hackems says:

    Just tried this today with my 3.35 ofw vita, I feel like I’m doing everything right. but when I turn off my wifi, turn off vita, turn it on and go to the liive area notifications, It just says paused. am I doing something wrong? I’m using psm runtime package a the update payload a well.

  25. xcero says:

    I installed PSM Dev for Unity but the problem is the version is 1.00 and when try to open ..You must update this application. to 1.06(27 MB) . It is OK if update? I decide update to 1.06 ,and when rejuvenate ask me to enter your PSM Dev Assistant version number, im typing 1.06 , is waiting to connect , Finally i go for Email and hackinformer choose the option I used PSM+ before and want to refresh my license.
    I recive a email and install inside Development Assistant VitaDefilerClient ans show me Hello World Script,

  26. Richie456 says:

    I’m stuck in QCMA every time it asks me for update I’m ofw 3.35

  27. mauricisti says:

    My psvita is on 3.36 and i’m trying to install Unity, but when try to connect to qcma the vita pops up a message to upgrade the psvita. How solve this ??

  28. john says:

    Running 3.36. QCMA does not work. System requires update. Fixes listed in comments above also don’t work. About ready to call it quits. Maybe I’ll come back in 2 years when someone actually hacks this system successfully.

    • progmaer1515 says:

      Try disabling wifi and enabling airplane mode. Then just reboot the Vita. It apparently still has the official update xml file from Sony.

  29. durr says:

    the game update wont pop up either becouse it asks system update first so this guide isnt possible to do

  30. derpina says:

    this is not possible because when choosing game update it requires system update

  31. Reilly says:

    Ive followed all of the steps very carefully, im pausing my updates the disabling wifi and restarting. when i reboot my downloads are just paused as they were before i disabled wifi. how does pausing download before disabling wifi cause an update to fail? ..since the update is already paused. it just isnt workin…unless im missing something. on firmware 3.51 i have unity 3.20 on my vita. tried updating both borderlands 2 and the playstation mobile service but nothing seems to work. downloads just will not fail.

  32. Darren says:

    Have I missed the boat on this?

    I have a vita running 3.50 but there are no games on it as I have just brought it from ebay, solely for the reason to put retroacrch on it and play old games. I have set up the email. but I cannot sign in to PSN without it asking for an system update.

    Can I use this update as required by steps 7/8 or dose it have to be a game that needs to be updated? I don’t want to start the update and not be able to go back if it not right.

    If I need a game to update can I use a physical game and go that way?

    Any help you guys can offer will be much appreciated as I’m starting to wish I hadn’t stated

  33. Ryussf says:

    Everything til step 16 goes fine.
    I turn on wifi, go into system and update PSM Runtime (ps mobile), and it starts download 2 files. PSM runtime update and a PSM runtime 2.0.1 file,
    I pause both of them at 25%
    Go into the email, run the first attactched file, exit program without clicking ok, start email, run 2nd attatched file, exit and close email,
    turn off wife, reboot Psvita,
    click on the corner bubble and hit “resume all”, they fail :
    Reading “Could not download (NW-10759-2) on both files, however no new bubble appears. :/

    What am I doing wrong? Please

  34. Degree says:

    So,

    I installed Unity (but still can’t get a licence), and I read everywhere that Unity cannot use rejuvenate, but there are no links to the Dev Assistant, and only to Unity.

    So has this been ported yet? Will it be ported?

  35. google says:

    Fine way of telling, and pleasant piece of writing to
    take facts concerning my presentation topic, which i am going to deliver in college.
