Let me get into this:

"Those who automatically received the 3.61 update can delete it and manually downgrade back to 3.60"

The writter of that article can't express his/her ideas properly nor clearly. So then...

The automatic update can be received when the PS Vita is configured to download automatically any update package. The point here is a mis-interpretation of the concept of an update. You are not updating your Vita's firmware just by downloading the update package, nor downgrading the Vita just by opting out of such update and deleting the update package.
As long as you don't apply such update your Vita will stay on the firmware version it was before the update package was downloaded.

We need to learn to interpret and understand what we're reading, as much as learn to express our ideas properly when writing.

Hope I did it properly here.

I am going to hold onto my 3.60 FW Vita forever as it seems a downgrade based in software will never happen.

Since we have Henkaku on 3.60, nobody AFAIK is searching for a downgrade method nor an exploit for any firmware version >3.60.

But can't say if this is bad or not. i've got my Vita on 3.60, and it will stay on it forever, just like yours.

It's bad if the developpers aren't interested in a develop a exploit >3.60 I don't see why this would be good.
Dude think about it:

Why do you need CFW on 3.67 ?

For Online Play ? Most likely you will get banned XD
For new Games ? What new games ?, I mean most of them are on other consoles too.....


There will be a Developer in the future who cracks the system completely like for example the Nintendo DS(i) that gets the first real exploit now.

The problem is that Sony did a lot of things right in terms of security:
- ASLR to prevent savegame exploits, most of the code is proprietary so Devs can't just adapt some bugs from for example Bugzilla, the PSVita has a very small attack surface...(except the 2k Syscalls XD) (memory card for example is proprietary -> no HBL loading from SDCard like on the 3DS),
- Hardmods on the PSVita are impossible without a microscope and really good soldering skills (missing testpoints for Nand Dumping)
- and f00d is very difficult to reach because you can comunicate with f00d only via Secure Kernel so you have to find: a userland exploit, a non secure kernel exploit, a secure kernel exploit(, a boot exploit) and a f00d exploit to completely hack the system (that's the knowledge from the Wiki atm).


Well, I have still hope that someone will accept the challenge and crack it open someday (or I will do it when I have enough knowledge to try something like this XD)

For everyone intrested in knowing more about the PSVita, I can really recommend yifanlu's blog and this post: https://yifan.lu/2016/12/31/state-of-the-vita-2016/
There are 2 Wikis avaible right now, https://www.vitadevwiki.com/index.php?title=Main_Page (more focussed on overall PSVita) and
https://wiki.henkaku.xyz/vita/index.php?title=Main_Page&mobileaction=toggle_view_desktop (good resource for the internals of the PSVita, Kernel, Syscalls, Boot Process....)

I apologize for my typos ;)
Take it with a grain of salt, I may have some false knowledge (for example I am not sure if something like enso is needed for exploiting f00d, but I think it's needed...)

currently pinouts are known
currently we can communicate with f00d but no exploit
currently the vita is still active
most of the games I want are 3.61+ (mainly 3.65)
but some private userland exploits exist 3.61+
but good info

Games, DLCs, updates that requires 3.67?

This is fake, i use Resident Evil Revelation 2 with the online missions and i don't get banned never.
The new games: https://www.reddit.com/r/vita/wiki/games/releases/dates/fullna
I don't want to buy another console to play the same game lol

what do you mean by the vita is still active ?

Some guys still developping, reversing and create new homebrews.

My point on this is more into the fact that finally, after all the previous intents (from years ago) on getting a fully working exploit, we got Henkaku, which wide opened the Vita for homebrew development. And since we have it, homebrew development on the Vita has vastly increased and we can enjoy an -almost- totally free 3.60 Vita as final users.

I know this lets Vita's on >3.60 firmware version out of this "freedom", but it would be worse not to have Henkaku at all.

    i thought everybody knew cocktails are like 75% ice
  • Veho @ Veho:
    Yeah but not like this.
  • Veho @ Veho:
    It's not like they're complaining that their Slurpee is 99% ice or something, but if the cocktail calls for "shot of vodka, shot of vermouth, shot of gin, shot of Campari, three shots of juice, squirt of lemon" and ends up being a thimbleful of booze, that's a problem.
  • The Real Jdbye @ The Real Jdbye:
    the funny thing is cocktails in norway are only allowed to have 1 20ml shot of booze
  • The Real Jdbye @ The Real Jdbye:
    so..... yeah

    we're used to only having a thimbleful of booze

    same thing if you want whisky on the rocks or something, you can't get a double
  • The Real Jdbye @ The Real Jdbye:
    but you could buy as many shots of whisky (or anything else) as you want and ask for a glass of ice and pour them in
  • The Real Jdbye @ The Real Jdbye:
    it's dumb
  • Veho @ Veho:
    Maybe.
  • Veho @ Veho:
    There was a comparison of the number of Ibuprofen poisonings before and after they limited the maximum dosage per box or per pill (i'll look that up). No limit on the number of boxes you can still buy as many as you want, so people argued it was pointless.
  • Veho @ Veho:
    But the number of (accidental) poisonings dropped because drinking an entire package of ibuprofen pills went from "I need a new liver" to "I need a new box of Ibuprofen".
  • Veho @ Veho:
    Here we have ketoprofen that used to be prescription-only because of the risk of toxic dosages, but then they halved the dose per pill and sell them in bottles of six pills apiece instead of twenty and it doesn't need a prescription any more. Yes you can buy more than one bottle but people simply don't.
  • Psionic Roshambo @ Psionic Roshambo:
    Usually accidentally overdose of ibuprofen here is from people taking like cold medicine then ibuprofen for a headache and the combination is over what they need
