    Thanks wololo for the information!

  2. Pwned says:

    It’s very easy to compile the source:
    – Install Minimalist PSP SDK
    – Open Command Prompt (with admin rights) and cd /d into directory into downloaded source/eLoader, and type make.
    – It will compile and 2 files will be – h.bin hbl.bin.

  4. wal31 says:

    hey good job wololo, thanks 4 the info,i thought it was possible to create a HEN based on that, anyway keep going man!

  5. VV says:

    user exploit could possibly run kernel exploit to gain “full”access environment.
    However, definitely piracy would follow up.

  6. D0nk3yPunch3r says:

    i do not talk like i know i am only guessing and would love for some correction. but how from an exploit would gain full access or even go from the type of exploit this is to a kernal. i dont think it’s possible right? i would love to be wrong. As for the piracy it will always be a facter i find it sad that i came into this hole psp scene soo late way after the golden age, but to see cfw on my psp bright would be a sight to see…

  7. wololo says:

    D0nk3yPunch3r: getting kernel access through a user exploit is possible, and actually it’s always the way it happens. Before you can think of calling a function, you need at least user mode access. Once you achieve that, the idea is to call (from user mode) a kernel function that has a vulnerability. (Easier said than done)

    keep up the g0od w0rk man.. all i want to play is tekken 6.. but it will never be happen anytime s0on(unless i will buy the effin umd).. my psp is 2004 v3.. fw 5.5.. i am very very sad.

    Hi, this exploit and the loader created for it is awesome! I was so annoyed when my psp 3000 came fresh out the box with 5.50, my aspirations of ever playing pokemon blue on the train destroyed.
    And i have been following the scene since waiting for something like this!

    I had a question though for you. I am aware that at the moment only simple HB can be loaded, and it’s just umode. But i am also aware that the kmode exploit that davee used in chickHEN was not patched until the release of ofw5.51 – which is why i think alot of people are not upgrading from ofw5.50 – so my question:

    Would it be possible to use davee’s kmode exploit (used in chickhen) with this savegame exploit and thus make the HBL able to launch any HB or even a HEN? I know this only really helps those on 2000v3 and 3000 ofw5.50, but just a thought.

  20. jemina0514 says:

    ei u kn0w h0w to dec0de the chickhen r2? what was the c0mpiler used by davee to c0mpile that..

  22. flofrucht says:

    thx wololo..
    thats the best news 4 go user 4 ever..

  23. jemina0514 says:

    w0lolo y0ur so great..

  24. wololo says:

    jemina0514: Davee probably used the same compiler we all use, psp-gcc, which is basically gcc.

    For discussions on the code of Chickhen, I suggest you go to m0skit0’s forum at: http://advancedpsp.tk/foro_es/viewtopic.php?f=23&t=22

  25. jemina0514 says:

    d0mo arigato w0lolo-san ur such a great pers0n

  26. Psp says:

    When wil I be able to launch pspident04?
    Its really importent, because I have a 3000 with 8c and Fw6.20.
    I herd that there is a small chance that my Psp is hackable, so Iam about to do everyting that may work.
    I hope its a ta-88 v2 …

  27. wololo says:

    @Psp: your psp is not downgradable, you can stop dreaming now :(

  28. jemina0514 says:

    me too..

  29. Hack says:

    But I read that, when you buy a Psp and it already has a firmware under 4.?
    it is hackable.You can see witch firmware it has had on the original Psp box.
    There is a letter for example G. I got this Information on a Website but I forgot the Name xD.
    So I tink you can see it on the letter, if its hackable or not.But Iam not 100% sure about that.

  30. wololo says:

    @Hack: not for the psp 3000.

  31. jemina0514 says:

    yes all psp 3000 with greater 5.03 is unhackable and bel0w is semi hackable using the chickhen or any equivalent..

  32. Psp says:

    Yeah its a shame of mine, because the Psp had firmware 3.90 or something like that (Internet-Radio not includet).
    But I did not understand very much about Psp so did an Upgrade to 6.20.

  33. pspivan says:

    como se usa las rev 51 no logro cargarlas alguien me puede bdar un tuto graciias

  34. pspivan says:

    how to use the failure to charge 51 rev anyone can give me a tuto thanks

  35. Psp says:

    I dont know, but I have a 3004 8c and 6.20 and r49 with h.bin from r41 works ( http://download.mastercoding.net/psp/hbl/ )
    r56 also works ( http://salwh.vs.land.to/files/HBL_newest.zip )

  36. Psp says:

    Do you know the Tiff-Crash?
    It works even on 6.20, but there are just Tiff-Pictures like Chickhens.
    Tiff is not supportet on 6.20.
    So why does this work but Chickhen doesnt.

  37. jemina0514 says:

    tiff is supp0rted up to fw 6.20. but the tiff must be a pure tiff, meaning to say n0 c0de. i made a simple tiff picture and my psp rec0gnize the picture
    the cue is.. what if i put the c0de of chickhen in 0ther medium. say in mp4 f0rmat? will it w0rk? can s0me0ne d0 it f0r us. c0s my pc is ruin right n0w. thanks

  38. wololo says:

    @Psp and jemina0514: you guys need to study more the differences between user mode exploit and kernel exploit, and why both are needed for a HEN. Additionally, try to look for differences between finding exploits in games and finding exploits in the vsh.

    Tiff, mp4, etc… would all be a vsh exploit. Finding them is difficult because the vsh is coded by Sony with security in mind (unlike games which are coded by external companies). Here’s one way to look for such exploits: http://wololo.net/wagic/2009/11/08/psp-exploits-finding-crashes-with-fuzzing/

    Regarding tiff crashes, I’ve written a blog post that explains why the recent ones are not exploitable : http://wololo.net/wagic/2010/01/30/tiff-crashes-a-breakpoint-is-not-exploitable/

    For more info, please read my posts in the category “hacking”, they basically give you all the answers to your questions :

    jemina0514: you might want to fix your keyboard, it seems your letter o and the number 0 are all mixed up. If that’s intentional, then please keep that kind of writing for other sites, thanks.

  39. jemina0514 says:

    im so sorry wololo. thanks alot

  40. Psp says:

    Yeah thanks a lot. I didnt think that is was so difficult to find an Expolit.
