DevHook 0.51 has been released, and now emulates firmware 3.01! There are 2 different Ultimate Installers available for this release, Ultimate Installer v1.5.2 for firmware 1.50 and Ultimate Installer v1.5.2 for 2.71se firmware.
The installation is almost the same as the DevHook 0.50 installation however a couple of the steps are different. For instance, the supplied .bat file didn’t do its job properly so each step will be explained here.
Connect your PSP to your computer using the USB port and initiate the USB file transfer mode. I recommend making a backup of your memory stick first. I went as far as backing up my memory stick then formatting it to install DevHook 0.51 on a fresh stick. Follow the on-screen instructions. You will be prompted to choose which version to install. I chose the Full Install.
Accept the license agreement, then select whichever drive your PSP is. The files will now be copied to your PSP.
The files are now copied to your PSP, you can hit the circle button on your PSP and exit out of USB file transfer mode. Now head over to the GAME menu, and select the PSAR Dumper. This will load a program that decrypts everything that is needed. Once the dumper loads, press the X button.
Once everything is complete, fully turn off your PSP. Don’t just put it into power saver mode, turn it right off.
Okay, you can now turn your PSP back on. Once again go and initiate the USB file transfer mode. Access your PSP through My Computer, you will see alot of files and directories. Some of these files and directories your going to move, or delete, some you won’t touch at all.
The first thing you want to do is access the folder labeled “f0″ and you will then find a folder labeled “kd” go inside of this folder aswell. Once you are inside of the folder labeled “kd” delete the file “audio.prx”
Now copy audio.prx from the “x:\temp” folder and put it back inside of “kd” folder inside of the “f0″ folder.
Now access the folder labeled “dh” and create a folder labeled “301″. Now move select the “f0″ folder and completely move it to the newly created “301″ folder, inside of the “dh” folder.
Now go back into the “temp” folder and move everything inside of it to “x:\dh\301\f0\kd”.
Now access the folder in “x:\dh\301\” labeled “f1″ and create the following folders: “dic”, “gps”, “net”, “net\http”, “vsh”, and “vsh\theme”.
You can now go back to the root folder and delete the “temp” folder, the “DH_README” folder, and the file labeled “DevHook Setup.bat”. Also while you are deleting stuff, you may go into the “x:\psp\game” folder and delete the PSAR dumper, as it is no longer needed.
Turn off USB file transfer mode and go back into the GAME menu. Now you can Launch DevHook 0.51.
Once you are inside of DevHook 0.51 go to the “FIRMWARE” menu and select the 3.01 firmware. You can now start DevHook 0.51 and watch your PSP boot into the 3.01 firmware.
Enjoy 
Excellent read. I can’t wait to get this running on my own psp!!!
i followed all the instructions, when i boot devhook, and select firmware 3.01, it sas reboot and then the screen goes blank and the green power led stays on but then after 10 seconds, the pwoer led turns off aswell. what am i doing wrong?? i have firmware v1.5
Sounds like DevHook is crashing, try deleting everything, that was installed and try again. If that doesn’t work, backup your memory card. Format it, and start fresh. Only things I can think to try.
ty, everything went well except when i load up smackdown vs raw 2007, it loads up. no more black screen but now it’s stuck on the psp title screen (white psp screen). what do i do now? firmware is on 3.01, cpu clock on default, boot mode on dev menu. hlp pls
Bad dump?
i followed everything exactly but when i when to game after using the installation program there is no “PSAR Dumper” in the game menu. Any ideas why? (and im using FW v2.71)
followed everything, when loading devhook, reboots into dev hook mode. I can see the game “yugioh”, but when when I try and play it, it reboots again, doesn’t play the game. Why do you think this is happening? I did a fresh install, formatted the card before. Running V 1.5
it’s wierd. i see the menu, says close menu, close devhook. i can hear the songs and see the game, when i close the menu and hit “X” on the game, it shuts off.
IT DOESN”T WORK everytime i try to work it it stays for like 10 seconds and turns off.SOMEONE HELP ME
how do u make that dash cuz my computer won’t let me \

I have a psp fw 1.5, I’m currently using devhook .46. can I just overwrite the files or I have to delete all of them first? Is there a chance of bricking my psp by installing devhook?
I tried to make new folders with the “\” symbol and my computer didn’t let me. Instead, I put in “_” this symbol. Is that going to affect my programs. I haven’t noticed any side effects. Yet. Were you aware of this problem?
i can’t get my CSO files to work. Any ideas?
i have FW version 2.82 and i want to know which devhook can i use… any IDEAS HERE¿?¿?¿?¿?¿?¿?¿?
THXxx
i just dont get it what is firmware? my psp version is 2.5 is something wrong wit that or it doesnt matter?
thanks for the info jason.
yonmor- it’s for 1.5 or 2.71 and yours is 2.5. so, either downgrade it ot 1.5 or upgrade to 2.71se (upgrading is proly alot easier and smarter thing to do) and choose the corresponding devhook installer then follow the steps above. am i right?
i’ve follwed ur instructions but i’m getting a blue screen that says settings are corrupted. What setting should i set in devhook to run my iso? using psp1000…v1.5
help help…i’m feeling lost without my psp
Viruz, just go through all of the settings. Sometimes this happens but is easy to fix. There is directions on the screen on what to do. Its been a while, but I think you press the Circle button to start.
I have fw 3.01 used Ultimate Installer v1.5.2 for firmware 1.50 is this the right one to use and if not which on to download. When i did SAR Dumper. This will load a program that decrypts everything that is needed. Once the dumper loads, press the X button.is does psp game start then it reads game could not be started
Hi GUys Just A litte Q hope i Get A reply
1. i used a 2.60 downgrader to get to FW 1.50 if i install a custom PRX along with the FW files which makes devhook load on psp boot is there a risk of BRICKING…….it says in the pack thats its only for custom firmware users but it should work if install the prx in the downgrade pack…….i dont want to take the risk of bricking.
Email me or make a post on this site
thanX
VER 1.50 psp (too scared too install Dark ALeX CUS-FW)
MAbie soon
whoa. im excited!!
thanks for sharing.
Ummm…out of curiosity, before I start any of this, would it be possible to run devhook while in another devhook?
For example:
I have a 2.71 FW (TA-082)
I usually use HEND and Devhook .4 to emulate 1.5
When in that 1.5 emulated FW would I be able to run the DH.51 successfully to emulate 3.01 FW?
Thanks to anyone who can help or is in the same situation:
