20w ago - Following up on his previous VHBL exploit and Sony's PS Vita Firmware Update v2.05, Tomtomdu80 has now made available a demo video spotlighting a PS Vita Half Byte Loader for Firmware 2.05 below.
To quote: We announced last week that developer Tomtomdu80 got VHBL to run with a new user mode exploit. A few days ago, The Z published a video showing Tomtomdu80′s exploit running VHBL perfectly on PS Vita's latest firmware 2.05.
Firmware 2.05 patches both the user and kernel exploits used with UNO to run CEF and ARK. It's also been confirmed that the latest Sony firmware patches several kernel exploits that were all relying on the same pattern (security issues related to the kermit wlan implementation). Technically, the end user is back to square one if they are on firmware 2.05.
Thankfully, there are still lots of usermode exploits available in many psp games, and some of them can be used to port, if not a psp custom firmware (a kernel exploit would be required for that), at least VHBL.
VHBL is a Homebrew loader for the Vita running in...
From the included ReadMe file: Vita FTP - Developed by Coldbird - Team PRO
This is a FTP Client for the PS Vita. Launch this FTP Homebrew via a HBL (e.g. HBL r160 via Monster Hunter) and then connect with your PC Browser to the given IP, it may be this one ftp://192.168.1.5, you should be able to see the memory stick directories of your PS Vita memory card, but just the stuff inside of the PSP Emulator.
Have fun transferring files without the CMA.
1. VHBL. You must have the Vita Half-Byte Loader for one of the firmware 1.67-1.80. This works on 1.80 MHFU VHBL.
Below is the guide, to quote from his blog (linked above): This guide assumes that you found a user mode exploit in a game, and that you were able to write a binary loader.
So now what’s next? Well, as you probably know if you’ve gone that far, the PSP scene doesn’t really like “hello worlds”. A hello world is nice, but it accomplishes nothing, it just draws Sony’s attention to your exploit, and you know the vulnerability will be patched soon, while nobody really used the exploit.
Well, the next step is, ideally, a HEN or a custom firmware. Of course, this requires a kernel exploit, and...
68w ago - Following up on his previous update, today PS Vita homebrew developer wololo has announced that the PS Vita Half Byte Loader (VHBL) will arrive shortly after March 1, 2012 with details below.
To quote: "This has been a tough week for lots of you, coming to my blog everyday to see that no new information was available about the release of VHBL. Trust me, it's been a much tougher week for me, making sure things go according to my humble plan, coping with a few more issues than expected, and overall, taking all the insults about "being a faker" or "trying to boost my ego" without being able to say anything else than "please trust me".
Ok, let's reveal a few essential things here, starting with the bad news: The game used by Teck4′s exploit is not available on the US vita store. Blame Sony and their "275 out of 900 PSP games available for your vita" scheme for this, not us. Part of the waiting time was to see if Sony would add this game to the US store at some point. It is obviously compatible since it is available in other continents, so my guess is that this is a marketing or a legal decision.
75w ago - Today PS Vita hacker wololo has made available a Half Byte Loader (HBL) development FAQ for those interested in progress thus far on Sony's PlayStation Vita handheld console.
Also below he states that he has ported HBL for Teck4's exploit successfully and updated to EU/US versions.
To quote: I managed to port HBL to the US version of Teck4′s exploit in exactly 45 minutes (including writing the savedata exploit and the binary loader), which is a new personal record, thanks to the scripts included in HBL's repository, and also to the fact that the different versions of the game are internally fairly similar (which is to be expected because technically the game is supposed to be the same, just translated, but I seem to recall it wasn't that easy for the Hotshots golf exploit)
I also updated the EU/US versions of this HBL port to get the tweaks I worked on for the past weeks in order to get a fair amount of homebrews to work.
The next step for me is to write a bit of documentation on how to use all this, and then patiently wait. As far as a release is concerned... well check the FAQ I wrote yesterday.
