Sponsored Links
146w ago - Following up on my previous post, below is a video demonstration for those interested dubbed PS Vita Crash CMA Debug Time via Xcode Execution.

I just released a fast small video to show the crash and freeze of the PlayStation Vita system using Xcode Execution. I also explain how to check every information coming from the CMA to PS Vita (debugger).

Below is a pastebin with tutorial and the video that show you something interesting.. As I promise and I do what I said

The tutorial to Debug CMA PS Vita Under MacOS and Xcode: [Register or Login to view links]

CMA Debugging PS Vita Under Xcode Execution Tutorial

You need a Dev account Apple to have Xcode that you can use your MacOSX under a Development Environment

1- Launch Xcode (Spotlight -> Xcode)
2- Create a Empty Project (MacOSX)
3- Enter whatever name on the Product Name (For Example PSV)
4- A new window appear, change command-line builds use Debug than release
5- Click on BreakPoints
6- On the top menu of the Xcode, choose Product and make a new scheme and name your new scheme psv for example, press ok
7- A new windows appear that you can edit your scheme on the left menu you can see RUN click on it and edit the run configutation build configuration -> Debug Executable (you need to choose the CMA.APP) for that, just click on None to Other and here you choose the CMA.APP Debugger, you can choose ever LLDB or GDB (choose by default GDB) Launch = Auto
8- Choose Diagnostics and here active every option Memory Management (malloc, Guard Malloc, Objective-C) Logging (Memory/execptions/Dyld) Debugger (Legacy->Stop on debugger and debugstr) Click OK (don't forget to active breakpoints before click Ok) click OK
9- Plug-in your PS Vita and Click on RUN (if you are connected in Wifi you just connect fast and disconnect)

Xcode/IO Framework, etc it's the best way to exploit the PS Vita under MacOSX and as you would see, the Sony have a strong access to your kernel system that i really don't appreciate and can control everything

The PS Vita use also NFS -> Network File System and Open Remote System File that ping pong between the PS Vita and Sony Server.

Hope that would help some smart dev And here the video that show you a example of what you can do





Some PS Vita user ask me the PS Vita Windows Driver that i made it's available on the older thread PS Vita 1.50 Firmware but I reuploaded the driver that you don't need to search

Griever2Kx It's hope to you, if you want to use your PS Vita use it and update don't worry about the update right now, anyway FW 1.06 is a firmware with too much bug that give you some problem it's unstable and some app/game will not run correctly with this Firmware. It's more easy with 1.06 but also more unstable.

Hi again Nabnab,

About my previous messages, if I was talking about dev it's because I'm a software engineer and I would like to participate and help if I can. I have lots of free time these days (no more work, long story and not the place to talk about it). Please try to reach me or give me a way to talk to you (live messenger, gtalk, etc).

See you soon,
d3mone

I really appreciate your work. And yeah..the Dev's nowadays... there just want Fame or teasing other People the whole time. Where's the Time with Dark Alex... where Dev's work together and sharing things because we all have the same goal. To free the PS3 or Vita.

Thanks for your Infos

Off-Topic Question. Do you have some experiences in hacking the 3DS. Because it's hard to find an useful exploit...

First step of an exploit ? this is more than a first step of an exploit, i didn't start to work on it from yesterday. You would have any homebrew you want after exploiting the bootloader with for example a bootstrap. Sony can't fix and will never fix, because is under ARM architecture not even related to the software. Actually the CMA only work under a monitor mode.

I'm not teasing, i'm explaining and release my research and my works that you can find on pastebin most part can help
dev to figure out how to exploit the PS Vita under USB dev.

The USB debug trick ? you mean the key buttons was used for technical testing, they fix the trick, like the one for the hidden information, etc.. but i'm not talking about a trick in here.

Everyone will help me ? if you talk about the dev, i know some that don't want because too busy for that or other that with big ego and business don't know how to work together, the fact is that for a simple user you can't understand what going on my research, for a dev it's more than useful (big deal) that help a lot on for exploit the PS Vita system.

that don't change that much than a priority encryption with ARM architecture from smartphone.

First you cant port a driver from higher fw's without having the keys for it. Then i allready asked some REAL dev's from scene which working on interesting stuff like psx and psp games for ps3 and they sayed that this is totally useless. They also have a vita and for sure are more skilled so peoples don't be too exited. About sony cant patch... uhmmm... what does team overflow sayed about there exploits and what have sony done ?

If some one of you really think sony cant patch this then well just wait.

And if you now want to know of which dev's i talk well... some one off the old gitbrew crew

The problem on CFW 3.55 are the Vita Drivers. I don't know much about FW's above 3.70 and if there's a way to extract the Drivers and install them to 3.55. I ask KaKaRoTo by Time if there any Possibility... but what i read, this is useless as you already sait PS3 = just Host.

And if you have fully access to the Vita there should be a way, because as you say, the Vita control the transfer more than the PS3. Or we could work on an custom File Manager.

Okay but you've mentioned the Netflix app. I've already read some articles and people say that the App is buggy. It sometimes slow down ect... Have you take a closer look on the App already ?

Yeah, but you give us some hints how to probably get the Keys...

And Dualboot/Bootstrapping....hmm sounds good. I hope to see something soon from you

I take a look on my Vita tomorrow
