    dony by xyzz which isn't random user to the vita scene.

    what is F00D:

    What we don't know right now is what part of F00D is hacked and if it even works.

    Henkaku is lvl2 hack. Trustzone is lvl1.

    If this is true and it works it basically means custom firmware and you won't need run offline or browser hack.

    May have more to look forward to than psx/ps1 support in adrenaline soon, nothing wrong with that.

    Nice. xyzz is definitely a trusted person on the scene and it's not April's fool's day yet so that hack should be legit.
    No idea exactly what this hack truly allows atm, it might be of limited use, but even if it is it should be a good starting point.

    EDIT: Also realized that we have no idea if this is actually a 3.60 hack.
    Might very well be something that only works on a lower firmware xyzz was working on.

    Gambia, The
    With lv0 we can sign everything. When lv0 was released in the ps3 scene, we was able to build CFW's higher than 3.55. Maybe in vita scene it is the same thing and we can build CFW's higher than 3.60. That means we can go to PSN again and play actually vita games. But 3.60 can be the base firmware to install higher CFW's. It's only my theory about that lv0 thing. :)

    Nope, on PS3 you could sign your own binaries because Sony messed up their ECDSA implementation which was present in almost every part of the system.
    Once lv0 had been dumped on PS3, people could extract neccessary parts to calculate the private keys for the rest of the bootchain.
    That's what got you CFWs which are newer than 3.55 ;)

    On PSV a F00D exploit means that for one, we can get all the keys and decrypt stuff on our PC and second, if you manage to implement this exploit at boot time, have a coldboot exploit.
    They are probably trying this currently, since they are messing with hardmods to externally rewrite the NAND during their tests -> check Davees twitter ;)

    So... Possible cfw and perhaps a downgrade???

    Could care less about cold boot since rarely have to boot henakaku again and usually leave it at standby. The offline boot or online boot doesnt even bother me. A cfw that can run recent game. Ans go online sounds nice if possible

    It is true that you rarely need to restart vita but at the same time cold boot gives you a lot of options like downgrade/upgrade, write protection to parts of firmware that you don't want to upgrade and stuff like that.

    With proper hack you can essentially run newer firmware with parts of old one. Meaning latest updates, full access to PSN etc. At least this is how it is done in 3DS scene.

    I believe that is also how it was done with PSP and PS3's CFW...
    Let's see what comes from this, having a "boot1"/lvl0 code loading is a huge plus in case something screws up.

    maybe both xyzz and davee were at it? ^_^

    meh who nows but all i do now is that R/Vitahacks has an exact thread like this one and Davee called it out. The same day Food went public on Github.

    too many factors so i think its related

    Best part IMO is yifanlu basically telling Davee "yo i've got anything with 3.61, 3.63, or spoof on block, you should try it sometime"
