    Exclamation Fw 2.80 Decrypted

    I was looking around the main PSP news sites (Including DC emu ). I went on PSP-Hacks and found this had been posted.
    GmDude66 has decrypted the latest firmware,2.80!
    Heres what the post said:

    QUOTE FROM PSP-HACKS
    -------------------------------------------------------------------
    GmDude66 from pspupdates has managed to fully decrypt firmware 2.80. Below is a changelog of files that were added/changed. And yes, 2.80 uses the same encryption key as 2.70 did.

    f:\dh\250\flash0\kd\resource\
    me_blimg.img

    f:\dh\280\flash0\vsh\module\
    dd_helper_utility.prx

    f:\dh\280\flash0\vsh\resource\
    lftv_rmc_univer3in1.rco
    lftv_rmc_univer3in1_jp.rco
    lftv_rmc_univerpanel.rco
    lftv_rmc_univerpanel_jp.rco
    lftv_rmc_univertuner.rco
    lftv_rmc_univertuner_jp.rco
    netfront.skn changed to netfront.rc

    f:\dh\280\ipl and f:\dh\271\iplcomparrison
    psp_ipl.bin changed to psp_nandipl.bin
    psp_ipl.bin_p1 changed to psp_nandipl.bin_p1
    psp_ipl.bin_p2_040F0000 changed to psp_nandipl.bin_p2_040F0000
    psp_ipl.bin_p3 changed to psp_nandipl.bin_p3

    Please note 2.80 has yet to be emulated with DevHook - this is just the first step - a decrypted copy of ‘reboot.bin’ is still required.

    Attached is a revised version of BOOSTER’s DevHook Firmware installer:

    1. copy the contents of this zip archive to “ms0:/PSP/GAME”
    2. extract “DATA.PSAR” from the 2.80 EBOOT update [using PBP Unpacker] and copy it to the root of your memory stick (ms0:/)
    3. run this app. The result: a 2.80 dump in “ms0:/dh/280″
    ------------------------------------------------------------------

    As it said,It cant be emulated on Devhook yet because a decrypted copy of ‘reboot.bin’ is still required.

    All the breakthroughs came out as soon as I updated to 2.71
    Youl have to wait a bit longer till its emulated but im sure the wait will be worth it

    It was only extracted, not actually decrypted according to qj(which is where the person is from).

    I tried decrypting it right away. the decompress works fine, but that prx decrypter doesn't. It looks like it does something, but just dumps a bunch of empty files

    Exactly. Go read the DevHook 0.46 at QJ. It can not be decrypted yet.
