PS Vita Half Byte Loader (HBL) Progress Update By Wololo


Sponsored Links
151w 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 [Register or Login to view links] and how to [Register or Login to view links]. 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.

I wouldn't be surprised if the US launch saw an even later firmware (1.6?). Hopefully the scene for Vita stays motivated and finds some reliable homebrew.

Indeed, at least he didn't reveal them specifically. I hope the launch firmware isn't very high for the US.

I hope a couple of exploits are kept secret until we actually can buy the damn thing.

Since reporting on his last flaw uncovered, PlayStation Vita hacker SKFU has found a few new vulnerabilities in Sony's PS Vita handheld gaming system.

To quote via [Register or Login to view links]: Few hours ago, developer SKFU (known for his work on the PS3, but also recently for some investigations on the Vita security) posted a screenshot of his Vita showing some HTML in what is supposed to usually show official messages from Sony’s updates or packages.

Knowing SKFU's passion for everything network-related, I'm assuming he's doing some tests using some local DNS changes... or maybe he managed to put some of his own files in an official package? That would be exciting.

In previous tweets this week, he mentioned he found 2 potentially usable vulnerabilities on the Vita

VITA is back to life, since last tweet found 2 new possibile vulnerabilities. If it runs good, news in blog this evening!

That was, however, 2 days ago, and his blog wasn’t updated since then, so I’m assuming he ran into a few issues. (the “back to life” comment refers to the official 1.52 firmware which bricked his Vita…or appeared to do so... which turned out to be that the battery had to charge for almost 24 hours before the Vita accepting to turn on, for some reason)

Obviously lots of this experimentation will probably not lead to anything, but for now, every bit on info on the internals of the Vita is interesting. Let’s keep digging

Also from SKFU (linked above) is an update on the recent PlayStation Vita 1.52 Firmware status below, as follows:

Ok guys we tested the possibilities on firmware 1.52 for a few days now. What I can confirm is the following:

  • Tech4's exploit still works
  • Wololo's HBL still works
  • Everything I research atm didn't change from 1.50 to 1.52

If that is fine for you, there's no reason not to update. Anyways, I have to mention that this can change without a firmware upgrade!

If you are online with your PS VITA, it can download and install silent updates for any application which runs in usermode and has nothing to do with system critical modules.

The good is, those updates are removed once the system is restored to the current firmware, so it would not be a major problem to remove a fix.

Wasn't it actually 1.51 as it was released around that time?
