Update: This seems almost to comical, but apparently the 2.8 decryptor recently released also works on v2.81. Someone probably should get fired over that one . Anyways, looks like now their argument of using a memory stick bigger than 4gb is completely useless now…

There has just been a release of a decrypter for the 2.8 firmware; hopefully an update for Devhook will follow soon.

For now the it can decrypt the firmware files by means of the PSAR dumper. Dark_Alex has modded the dumper so that it can now dump that of the 2.8 firmware. Since I don\’t have much to say on the subject I\’ll let QJ do the talking (or for those who don\’t care to read the whole article, yeah this was a post of news from QJ, within the lines) as stated before):

Mathieulh stopped by our forums to tell us that a new version of psardumper (modded by Dark_Alex to dump 2.80 files) is available. Dark_Alex modded psardumper for 2.80 which was originally created/coded by psppet. This psardumper will dump reboot.bin and other necessary 2.80 files for devhook emulation!

This is quite some exciting news as it has been quite some time since 2.80 has been released and many have been anxiously awaiting this day. The only thing that remains for us to wait on is an update to devhook that will allow us to emulate 2.80! So, now that we have the files extracted/dumped, it is only a matter of time before we are emulating this precious firmware on our 1.50 firmware with devhook!

To install, extract the data.psar (I suggest using PBP Unpacker) and place it in the root of your memory stick (data.psar). After this is done, make sure you have the decrypter/dumper file in the correct folder (PSP/Game) and execute it on your PSP. The program will then dump/decrypt the necessary files onto your memory stick. This program is legal, however the files dumped using it are protected under copyright laws – so do not distribute them!

Hopefully we can expect an update on Devhook soon, let\’s hope $ony doesn\’t try to squelch our attempt at another update like they did before: http://pspupdates.qj.net/index.php?pg=49&aid=60558
