PSP Firmware v2.81 Decrypted! (Yes the New Firmware)

[wraggster]

Dark Alex is damn fast, he has already released a Decryptor for the 2.80 that even supports the v2.81 firmware released today, heres what he posted:


I added support to psar dumper to decrypt 2.80.
Decryption could be done thanks to remains of kernel stuff in the 2.80 user ram dumped thanks to the recent tiff exploit.

UPDATE: added 2.60-2.71 decryption support. Until now, a 2.60 was required to decrypt those.

Mathieulh added this comment:


To anyone wondering, no you can't use 2.8x on devhook yet, why ?

1 - You need another compatible devhook version

2 - There is a new security in 2.8x reboot.bin that allready existed in 2.00+ IPLs, in 2.00+ the module possess a sha1 key area that is beeing generated by 2.00+ updaters before the modules are actually copied to flash0.
This key area is generated from idstorage data which is unique in every psp.
The 2.00+ IPLs check if the modules key area match the idstorage data.
If it didn't then it wouldn't let the module load. The reboot.bin didn't have this security, but 2.80+ reboot.bin now does, so technically you can only devhook a 2.80 firmware if you use the modules from your own nand dump. (which can only be achieved if you manage to dump the nand on 2.80 and extract lflash from it, at this time only people with a modchip can do this)
There are 2 ways to bypass this limitation, either we hack reboot.bin to load the modules regardless of the sha1 key area check results, either we manage to generate the sha1 key area on the modules.

The second solution is the best and can be achieved by performing a deep reverse into the 2.80 updater and reproducing its work.

Yeah Im First

DevHook should come out quick

[Nafogel]

damn he's fast, sony just cant keep up with the homebrew scene, and yet sadly, they will probably never give up. I bet you a 2.82 will probably be out within the next week or so, lol, and it will probably be decrypted within a few days, double lol

[ExcruciationX]

Damn Fast! Booster should get on the stick, and release Devhook! Notice we all use the word "Damn" in our posts!

[BL4Z3D247]

Yeah Im First

DevHook should come out quick
i hope so, way to go Dark_AleX :)

[The_Ultimate_Eggman]

WE NEED DEHOOK !!! the capaign starts here lol.

[dejkirkby]

Damn, you guys don't mess about! Keep it up!

[YourStillWithMe]

agreed devhook is in need now screw emulating 2.80 lets just get 2.81 going to save ourselves longer now they probably wont release many UMD's with 2.80 now though it'll be like the 2.01 update

[juliusceasar]

Great news, but the reboot issues sound like there may be a delay with a devhook update (not forgetting that Sony got booster to shut the devhook site down too). Nice one Dark Alex

[pkmaximum]

Booster come back D:

We need this firmware emulated. I don't see why nobody is working on NAND flash emulation. That is 100% legal and if we accomplish that we will be able to emulate any firmware. Only we wouldn't be able to add stuff to it as it would be as normal as any other firmware.

[The_It]

if a new firmware can be decrypted the same way as an old one, maby you should try and keep that a secret and hope the people ofer at sony don't recognize it so they won't try and fix it.

[QueadlunnRau]

Oops

[Emeriastone]

Speedy decryption keeps the Sony doctor away.

[nami]

he´s damn fast. but i have a question: is bosster working on 2.8 for devhook?!

New for 2.81: A patch has been added to address a security vulnerability in the system software. $<-- LOL

[jwilds73]

Sony's attitude will change once Microsoft releases it's own handheld with homebrew support. Microsoft is already dabbling with homebrew with it's $99.00 a year bit for homebrew developers with the Xbox 360. If all goes well here then hopefully Microsoft will make it's handheld homebrew enabled right out of the box.

[NoQuarter]

It really does seem like sony just can't keep up,unless they don't want to and just do the updates to not upset the licsensed game companies.
Really, sony has supported homebrew,they just can't do it fully because they make their money from the licsenses and devkits.
I still think sony is playing both sides of the coin to obtain a greater market share.

[Screwie5150]

Yeah Im First

DevHook should come out quick


What are you like 10??? who cares your first!!! this isn't PSP-Hacks... grow up!!!

Can't wait to use in DevHook... Nice work!!!

[SSaxdude]

I hope Booster updates Dev Hook soon. Take that Sony!

[The_Ultimate_Eggman]

LOL !

alraedy decrepted !? u guys work so fast its unbeleivable as soon as i get home from school i get loads of cool stuff ! thanks psp coders !

[felonyr301]

"this wont mean a thing if you aint got that wing" do wop do wop do wop do wop lol remember that commercial and when i mean wing i mean devhook.

[.:}<3\/!}\{:.]

WE NEED DEHOOK !!! the capaign starts here lol.
im with u :D :D

[Alucard]

What's the rush on devhook really? We could wait until there is a game that needs it at least.

I am sure your cries are being heard and something will be available sooner or later.

[Gene]

I've gotta say the people behind this are genius

[[Roger]]

so what does this mean to me the 2.80 Firmware USER?

[mavsman4457]

']so what does this mean to me the 2.80 Firmware USER?

It means that as soon as they come out with a 2.8 downgrader in the future, you will have access to everything that 2.81 does. Which means don't ever update. This has got to be embarrassing for the coders at Sony. Either that or they're doing this on purpose and just being way too obvious. I don't understand why they don't just hire Booster and Dark_Alex and all of the other major homebrew hackers. We would be so angry but it would be a great fix to their problems.

[The_Ultimate_Eggman]

']so what does this mean to me the 2.80 Firmware USER?
A downgrader ect maybe just around the corner now the fw has been decrypted.

[gamesquest1]

i was thinking of trying this ealier as sony wouldnt have known about the decryped 2.80 today so i was thinking it might work on 2.81 but couldnt find the eboot lol wish i would have lol

[VampDude]

where can I get this firmware? (if available)

and decrypted??? as in it's already downgradable???

[bigrich68]

so can we use this to run homebrew or no ? soory still waiting for e loader 2.71 and im getting desperate lol

[pkmaximum]

so can we use this to run homebrew or no ? soory still waiting for e loader 2.71 and im getting desperate lol

Shouldn't be too much longer Bigrich68, I bet Fanjita is working on it as we speak :cool:

[gangsta_psp]

Sony must be on fire, or they are still cheering riiiiiiiiiiiiiiiiiiidge raaaaaaaaaaaaacer!

[mavsman4457]

As I said before this is just embarrassing. I guess they really don't care about their firmware's security anymore unless it's 3.XX.

[Kvonx]

yes bettter news evryday!!!!!!!!! YEAH

[Gene]

I agree with you 100%
i still think sony does things FOR the happy-ness of thier customers.

i always liked sony for its quality and customer care, until they became almost corupt with the firware assult. now it seems to me as if they are almost "alowing" homebrew to be hacked by the people.
maybe its a bit crazy, but hey i'm alloud to dream, right?

[razorak]

what in the world...they sure are fast i tell u...lol

[M!ckeY]

bloody hell, i think they enjoy having me shit myself over news like this all the time ;)

[sroon]

Wow shouldnt be much of an update since ic came out this morning!
LOL great work guyz!

( O ) ( O );)

[uhoh_hotdogs]

I literally laughed out loud when I read this. Sony releases the update and it is decrypted hours later . . . come on DevHook!

[Raekwik11]

great work!!!

[**1_Man_Matrix**]

Hah!

Next we'll see an update saying 'FIRMWARE 3.00 CRACKED!'.

And Sony will be scratching their heads goin 'but we haven't even released it yet!!!'

That's how good our coders are :D haha

[pibs]

LOL so many flaws..... so little time

[Hexx]

this is great news! LOL!

i can see the headlines......

sony releases new fir..m.... cracked!!!!!!

[mr_nick666]

[Kaiine]

I don't mean to sound like a noob, but how the hell do I use this?

[Veskgar]

I don't mean to sound like a noob, but how the hell do I use this?
Its not so much how you use this firmware, its how this decrypted firmware could enhance your PSP's capabilities someday. If this firmware is implemented into DevHook, it would basically turn your 1.50 PSP into a 2.81 as well. So you would have the best of both worlds.

[meanguns]

Devhook will not be released anytime soon sorry guys! as far as booster goes he is laying low for now! but, the new coders will reveal themselves in the next few months. It will be pointless to release devhook now as Sony is just testing the waters with a few new games that use 2.80 and 2.81. sony as a company is trying to close up the holes by releasing new firmware versions and only a few games that support them. they are trying to stop what has been going on! So devhook will take a while before the next new version is released. booster and the few new members now coding devhook are just waiting for enough games to be released before there next release so don't hold your breath waiting it will in fact be at least 4 months until the next release! and please don't look to me for answers I am just letting you guys know.

Sony is not trying to stop the homebrew scene but, are more interested in stopping the piracy of there products. given enough time they will close all the holes in the firmware, and believe me you they will not make this mistake with the next portable system they produce (((PSP II))). Moreover, we do not want sony to drop this system all together and announce a new one that does not support memory cards over 256 Meg. That only plays UMD's

Homebrew is here to stay, Sony does accept it but, they don't like it, as they cannot force us to update or introduce code that automatically updates our systems by law (these laws vary from country to country)...

The next devhook is most likely ready to go but, sony is playing a game called lets close all the holes in our firmware before our new 3.0 is released. The coders most likely realize the games that are being played here and are playing a waiting game of their own.

Enjoy!

[shadow77]

booster is still "around", you just don't know where. no one new is taking on fw loaders.

there are some extra securities in 2.8 that prevent it from being emulated. it is being worked on by some well known devs..

[defjamz]

Hi, im a newbie here.. just got my psp today. I need some help. i have no idea how to play games i have DLed. My system is v2.81. Where do i put the .iso or .cso files? Can someone be kind enough to help?

[mavsman4457]

No ISO or CSO file talk here. You will be banned. And if you have a 2.81 you cannot run anyhomebrew on your PSP. Too bad.

[AbusiveOwl]

where do i put the rar file

[blackrave]

You extract the rar file using WinRAR or something else that can open that file type.

[Video_freak]

There's no real use for it yet though. ;)

[matty 507]

Help!!, Im a noob, and I don't have a clue what u guys are talking about most of the time. I have 2.81, i want to play homebrew games????, Iv'e got a 256mb card, I dont know what Devhook is, or TIFF??? please help!

[JD/]

no homebrew for 2.81 nothing at all just dont upgrade is all i can say.

[wolfpack]

mmmmm decrypted 2.80 firmwire, tasty

[idothisforfiles]

doesnt seem to work

[LilSwish722]

where do i put this and what exactly does it do. will it update my psp to 2.81 or something?

[acn010]

hmmmmmmmmmm......... this is old but i didn't saw it........

[DPyro]

It was decrypted a long time ago...just waiting for a new version of Devhook to support it.

[acn010]

oh, that would be nice if it comes out (is it possible?

[LilSwish722]

what exactly does this firmware thing do and will it update my firmware someone plz explain!!!

[Cloudhunter]

what exactly does this firmware thing do and will it update my firmware someone plz explain!!!
It runs on a 1.5, and extracts and decrypts the 2.80 and 2.81 eboots. It wont upgrade your psp, but there is still no point running it.

Cloudy

[Diablo45]

wait so what does this new thing do? screw up our psp's or downgrade it i don't get it some 1 plz explain

[LilSwish722]

so if i have a 2.8 and run this, what will it do

[silver32]

There's nothing you can do with this yet

[sean468]

[HumanIce]

so what, if u install this can u play homebrew on v2.81 psps??
im sry im new plz answer me.
also can u tell me how to install btw
on what firmware are you on right now?
I can help you maybe..

EDIT: try searching for a 2.81 firmware (v2.81) psp downgrader on google, then downgrade to firmware 1.5, then update to dark_alex's firmware 3.40 OE, and you'll be able to play PSX games, snes, GBA, GBC, nes, n64, neo-geo.. all kinds of stuff, and emulators.. and some homebrews too, like doom-psp and quake-psp..
