*Actual progress made on hacking 2.0 by WAB*

The guy has a point, what's wrong with a tiny bit of proper english? I just love some of you attack him by showing even worse spelling and grammar then the orginal post. It's too funny!

But seriously, why hasn't someone tried to make some hacked firmware that can just bypass these problems completely? It seems like trying to hack firmware that is already in place is alot more difficult then just making your own firmware. All we really need is a slightly modified version of the 2.0 firmware with a backdoor for Homebrew access, but that still contains all of Sony's upgrades and v2.0 compatibility.

I suppose this might not be very legal, but then again, neither are emulators, loaders, and old-skool game clones.

Emulators are 100% legal, the games might not be. Well I still think to get your own firmware on it you have to hack the existing one to make it update into it...

Meh. Consider this: the line they changed was actually an address of a function that is suppose to be called. Changing the address might forward to a data/uncallable function or just one function already done. Wich causes a cycle.

As far as I remember, when I edited my 1.50 update file and replaced "1.50" with "1.52", the PSP started loading, then decided the file is corrupted. I assume changing the line WAB did, causes crash in the system before the file is approved/unapproved completely.

According my HEX editor:
as characters
STX, NUL, BS, NUL (before change)
STX, NUL, SOH, NUL (after)

STX = Start of Text
BS = Bullsh!t... j/k BackSpace
SOH = Start of Header
So if these values are text (wich I doubt), the "approver" saw start of header and as we all know, the number of starts should be equal to the number of ends (brackets for an instance). If that's messed up - I guess it would crash.

That's just an example but I DO think it's address of a function. So WAB didn't do a good job imo. Whoever comes out with the hack/exploit - I respect him/her/them. But just for showing that changing data causes crash... I can cause a crash with a .BAT file.

I thought the psp downgrader was suppose to come out 1st september its the 2nd now and no news nothing and what if these people are just wanting to ruin every 1's psp's have u seen there site stuff like how to kill a psp software u really trust them

[Festizzio]

not really that awsome.. all they did was change one simple number haha. yes, interesting work none the less, but i think few people relize how increadibly simple this was. anyway, dont praise anyone over this... hell the dude with his little update filename exploit has done this before basically.

This will be kind of important in the future... but its not really anything to get terribly excited about.

You can do it yourself to see what a I mean.

Well, yeah, it was simple after it's already been discovered. If you're the person trying to figure out something like this, then obviously it isn't as "simple" before you find out what it is.

ill tell you what im making a statement now and you can engrave it on my casket: if/when 2.00 is hacked i will never upgrade my psp again. no way.

[jesper]

me niether

[IndianCheese]

so do i need to hex edit the file to find this 02000800 he was talking about?

[jesper]

ohh i want the hack done...i want to play free games. IndianCheese ure a hell of a lwtter-writer in my opinion... :P
