177w ago - Following up on his previous update, PlayStation Vita hacker wololo has shared a progress update on the PS Vita Half Byte Loader (HBL).

Additionally, Nabnab has also made available a video showcasing some hidden PS Vita information for those interested!

To quote: A quick report: I'm making some progress on porting HBL to the Vita. Although I'm sad to say that I can't get syscall estimation to work, I got some major homebrews such as Doom to run already, so overall I think it's in an acceptable shape.

Because it is roughly stable now, today I focused on porting HBL to the EU version of the exploited game (I was working - obviously - on the Japanese version of the game so far). This went smoothly and I can confirm HBL runs fine on the EU version of the game, although of course I could only test on a PSP, not on a Vita.

I used the opportunity to refresh my two guides, how to write a binary loader and how to port HBL. The guides are now simplified, and the binary loader tutorial now has download links to the tools used in the examples.

Writing the first "usable" version of HBL for the patapon exploit took several developers and about 4 months. Thanks to the portability of HBL, bringing it to Teck4′s exploit took me only a few days. Adapting that to the EU version took a couple hours (including porting the exploit itself), so I am confident for the US version.

No big update of my works but here the driver PS Vita libusb a made for Windows (x86/x64). you don't need to use anymore the generic driver ps vita from Sony.

Oh yes just to clarify about the 3 python script i made. This is nothing comparatively to the full script i'm making, the 3 script are here to show you that you can communicate with the PS Vita, about the helloworld, funny how some people didn't understand how the python script works.

First : I ask if the PS Vita is connected to my comp
Second : I ask to the PS Vita the information of the USB configuration
Third : I send a message to the PS Vita and the PS Vita confirm the reception with a Hello World.
The PS Vita can't really answer to a question but can confirm that received the question. I write the answer Hello World for the PS Vita to confirm the message a send to the PS Vita has received, if the PS Vita didn't received the message, i would have a error and not the print hello world.

Is like every Hello World, it's you write the HelloWorld and it's the product show the Hello World but the product don't understand what that mean.

You need to think that have different possibility to make a hello world possible on every platform.

Sure that the Hello World is not impressive but like i said it's one of the investigation that show you where to work.

About the claim some user have read my news post on monkeydesk and posted it on gbatemp but i or you never sayed that you have HACKed the con. I named the news with "PS Vita Hot News" and translated some posts into german.

This guy then made the post with "PS Vita hacked?" or kinda like that and his first words written was like "nabnab claims to have the ps vita hacked" but some other guyes on gbatemp with a higher rep teached them they should learn to read

Now it seems they understand. But i haven't read anything about that to copy a savegame exploit to the vita we will need your work, the debug mode enabled to get full access to file sys and place the exploit where we need them. Also im sure we can get hands on on some nice importend files of the vitas fw. But anyway they will fully understand when it's time for it

USB Debug mode allow more than we expect but it's pretty unstable for now. Every person who have a PS Vita can do it and without anything else than a PS Vita and computer

Oh yes i saw that some people said that i claim i have hacked the PS Vita. I have never said i hacked the PS Vita, i explain what i have discovered and what my investigation/work is about.

Actually some executions on the PS Vita are pretty unstable and give me some errors (a security from the PS Vita that i need to fix) but i am working on it. I keep you informed for any updates of all my work and i will show you how to reproduce it when it's easy to do but need to keep it a bit as a secret before the EU/US release.

Nothing about my works but i really recommend to use the last version of openCMA http://code.google.com/p/procfw/downloads/detail?name=opencma_r3.7z on Windows -> thanks to Virtuous Flame

Ok let's back to work now

Nabnab: Does USB debug mode allow much/anything that couldn't be done before? Or is it still in the investigation stage? Also, is it hard to get into, or is it something anyone could do?

Yep, you can always start a new thread and we can merge or promote any posts made from it to the main page.. this was our ongoing thread for the Vita FW and Content Manager so people started posting here but if you wish to start your own I'm all for that too!

I'm gonna wait the BIG BOSS if he/she (she -> just kidding what ! you never know) want to make a new Thread and move all on this thread, it's gonna be more easy to follow and update the works.

You could do a new Thread named with "Universal Vita Dev Thread" or kinda like that. But best would be to ask the boss he also can move all the stuff from here which hase nothing to do with the OCM to this new thread then.

Great about the wiki and shows you that maybe more peoples recognize your work then yourself expect

I also was surprised as i have googled for my work and have seen where else it get spreaded.
