Update: According to wololo (via wololo.net/2013/03/12/video-vhbl-homebrew-loader-running-on-vita-firmware-2-06/) the VHBL homebrew loader is confirmed running on PS Vita Firmware 2.06 with details as follows:
People who staid on firmwares 2.02 or lower are eagerly looking in Total_Noob’s direction for the upcoming major update of TN CEF. But if you’re one of the users stuck on recent Vita firmwares such as 2.05 or the latest 2.06, you are probably impatiently waiting for the “next” exploit release, if not a Vita native one, at least inside of the PSP emulator. If you’ve been keeping track, two VHBL ports have been publicly announced and not released yet. One from Turkish dev xmax, and another one from French dev TomTomDu80.
Each new firmware release from Sony brings the question: “did they patch the upcoming exploit, and did we wait in vain?”. Although it is very unlikely that Sony will spend the time and effort to patch a vulnerability they don’t really know anything about, we can’t refrain fearing it could happen.
After all, the only ones who are 100% convinced Sony is not spying on their users’ Vita error logs are Sony themselves. A hacker’s log could easily be scrutinized by Sony, to find out which games caused a crash of the device, and simply use this information to remove the game from their store, at least temporarily (ugh, am I giving them a bad idea, here?).
Well, fear not, as scene member TheZ has access to TomTomDu80′s work, and could confirm his exploit and VHBL port still works perfectly fine on firmware 2.06, as shown in the video below.
We could also independently confirm the that game used for TomTomDu80′s VHBL port is still available on the PSN in the countries we checked.
And for the typical haters out there, believe it or not, I do not personally control the agenda of every PSP/Vita hacker in the world, so no, I do not know when this is going to be released, and if TomTomDu80 plans on waiting for a more substantial firmware before he releases his VHBL port. However, when this happens, it will be most likely through a ninja release here, so stay tuned.
