Devhook is a bitch to setup if you’re going to emulate firmware 3.0x. Here’s a basic howto on what to do, assuming you have SE-C, otherwise, this might vary.:
1) Get PSARDumper 2 from pspupdates.qj.net (or dl.qj.net)
2) Get the 3.x update eboot.pbp, and devhook 0.51.0100 and extract all the files to the root of the memory stick. (If the GAME folder is running 2.71 kernel mode homebrew, put the launcher in GAME150 instead. You can check this in recovery -> Configuration.)
3) Get PBP Unpacker or PSPBrew and extract the DATA.PSAR out of the eboot.pbp.
4) Copy the DATA.PSAR to the root of your memory stick.
5) Get X-Flash (we’re not gona flash anything)
6) Copy X-Flash to your memory stick and make a FULL firmware dump (its number 13 or something).
7) To exit X-Flash, hold the home button in until the thing at the bottom fills up with yellow (red turns off the psp)
Make sure PSARDumper and crap is on the memory stick and start it.
9) Make a firmware dump that is encrypted and has sigcheck (X from what i remember)
10) On the root of your memory stick there will be a folder ‘f0′. Copy the entire contents of that to ms0:/dh/301/. When a box comes up asking to overwrite stuff, say yes to all.
11) Go to the XFlash folder on your memory stick (ms0:/PSP/GAME/X-FLASH or something. Not the one with the %)
12) Go into the subfolder called ‘Xflash’ and into the subfolder called dump.
13) Disregard the flash0 folder. Copy the contents of the flash1 folder to ms0:/dh/301/f1
14) Start devhook and test it out (remember to change the firmware in the menu and such).
15) If it works, congratulations, otherwise, get help at pspupdates.qj.net or the maxconsole forums.

NOTE: If you have a 32mb stick, this WILL NOT WORK. It wont fit by a long shot.
NOTE2: Don’t even bother downloading a pre-prepared dump of firmware 3.x for step 9 because firmwares 2.8x and above require the dumps to be individual for each and every psp.
NOTE3: In devhook while emulating 3.x at the moment, there are a few issues. For me, the Web browser gives a BSOD, and the system settings gives a BSOD. From a brief look, the camera feature appears (just guessing, i don’t have the actual camera myself).
The only things that have changed in 3.x are:
The new camera feature
The fancy visualisers (pic below).
PSP-PS3 connectivity.
PS1 Emulation.
