This tutorial is NOT correct, guys. You don't put reboot.bin in ms0:/dh/271/flash0 . It goes it ms0:/dh/271 .

Had to register to the damn forum just to say this once and for all.. :rtfm: . if you follow the very basic instructions in the text file included with DH .44 then you have no reason to need a auto installer. Its not a hard concept just simply read all the instructions and bang it works. If you can't really get this far then consider just upgrading your psp and living by sony's defined rules.

could you please help me with step 7:
Use the 2.71 Decrypter to obtain your own copy of a decrypted reboot.bin file, or make use of Google to find one online
Following the steps for 2.71 Decrypter 2.60 part

1. Be sure you have the F0 folder with the ENCRYPTED dump obtained in the 1.50 part.
2. Copy prxdecrypt27X to /PSP/GAME/ and start the program with the eLoader.
3. The memory stick will flash for some time. When it finishes to flash, restart the PSP

what do i do for the eLoader? i do not know what this is thanks

Hi guys !

I try to but thenew devhook on my psp.......
Here's a small guide on how to get it running:

1. Download Devhook 0.44 and put everything on the memory stick as usual.
2. Download the 2.71 Firmware update from our site.
3. Open the EBOOT.PBP with PBP Unpacker or similar and extract the DATA.PSAR file.
4. Put the DATA.PSAR in the root of the memory stick.

----This is where I cant understand........whats the devhook installer ?----

5. Run the included Devhook installer on the PSP (install flash0 and flash1).

I think I will be ok after...... :)

6. Extract Devhook 0.44 again and overwrite everything in the dh folder (its going to be a couple of .txt which include the path for the prx's)
7. Get a decompressed 2.71 reboot.bin from here. (Second entry. We cannot host the file on our servers since it's copyrighted)
8. Place reboot.bin in ms0:dh271reboot.bin


*Don't forget to delete ms0:dh271flash1registryin it.dat

I hope that I wont be a noob forever :P

Due to the error that's currently happening, here is the Guide. This should be fixed soon:




FAQ:

What is Devhook?

In short, Devhook is a homebrew application that allows a 1.50 PSP to emulate and run higher, official firmwares from the memstick. This includes features like running UMD games that require 2.00+ firmware, web browser, RSS feeds, and the Location Free player.

Should I install 2.5, 2.6, or 2.71?

It depends. 2.5 is a lot easier to install, because you don't have to track down hard-to-find, illegal files (reboot.bin). But, you can't play all games.

If finding reboot.bin isn't a problem, then do 2.6.

And if you want to do a little extra work, do 2.71, because it requires the flash1 files from 2.6.


Your psp isn't now a 2.50 or 2.60 or 2.71

Some people seem to think their psp is now 2.50 or 2.60 it is not just hold down the power button until the psp turns off completely, boot the psp back up and it will be back to 1.50. It never actually installs anything to the psp it just runs the dump from the mem-stick, if it made the psp update to 2.50 or 2.60 nobody would use it.

How to install new verions if you already have a previous version set up

Whenever you download a new version of DevHook you can insatall it without having to re-install the dump. When you have downloaded the latest version of devhook go into the MS_ROOT\PSP\GAME and remove the DevHook installer eboots. Now go back into the MS_ROOT folder so you are just presented with the folders dh and PSP, now just copy these two folders into the root of your mem-stick and then if a message comes up saying something like "If the files in the folder have the same name do you want to replace them?" click "yes to all".

Sound doesn't work in the flash player
Go to Settings->Sound->Keytone, and turn it on.


Step by step guide on how to setup DevHook 0.44 (firmware 2.50)

Before you start make sure you have a PSP with firmware 1.50

1. Download DevHook 0.44 from here

2. Go into the MS-Root folder in the DevHook download and copy the dh and psp folder onto the
root of your mem-stick

3. Download pbp unpacker from here

4. Download 2.50 update from here

5. Open the update with pbp unpacker and extract all the files to wherever you want (the file needed is the data.psar)

6. Get the data.psar from the extracted update and put that onto the root of your mem-stick

7. On the psp choose devhook installer and start that, then when you are in the eboot start the installer, at the end if you want to copy your flash1 read what is says on the screen, which should be something like "press O to copy flash1 registry files"

8. When everything is done open DevHook and use these settings:
UMD Select: (choose your iso, cso or --UMD DISC--)
UMD Mount: ISO ANYUMD
UMD Version: 2.xx > 2.00
Firmware: 2.50
CPU Clock: 222MHz / 111MHz (that is what I always use no problems)
Boot Select: Reboot XMB
Other: preload address: 0x88E00000 (tell me if this address doesn't work with 2.50)
*****REMOTE CTRL: Kprintf(115kbps) (not compulsary, unless you want to use the music remote)

When selecting a UMD Disc with the UMD Select option the other settings will be changed automatically so the UMD will run, the settings can be changed back later by pressing O when DevHook is auto-starting.

Step by step guide on how to setup DevHook 0.44 (firmware 2.60/2.71)

Before you start make sure you have a PSP with firmware 1.50

If you are planning on doing 2.71, you must first install 2.6, then install 2.71 next.

1. Download DevHook 0.44 from here

2. Go into the MS-Root folder in the DevHook download and copy the dh and psp folder onto the
root of your mem-stick

3. Download pbp unpacker from here

4. Download 2.60/2.71 update from 2.6/2.71

5. Open the update with pbp unpacker and extract all the files to wherever you want (the file needed is the data.psar)

6. Get the data.psar from the extracted update and put that onto the root of your mem-stick

7. On the psp choose devhook installer and start that, then when you are in the eboot start the installer, at the end if you want to copy your flash1 read what is says on the screen, which should be something like "press O to copy flash1 registry files"

8. Download the decrypted 2.60/2.71 dump from somewhere I have a link but cannot provide it (the reboot.bin will be what is needed from the decrypted dump)

8.5. (Only if you're setting up 2.71). Copy ms0:\dh\260\flash1 to ms0:\dh\271\.

9. Now from the decrypted 2.60/2.71 you downloaded you will need the reboot.bin, copy the reboot.bin into ms0:\dh\260\flash0 (or ms0:\dh\271\flash0 for 2.71) and also copy it into ms0:\dh\kd and replace the one that is currently in there

10. Now use the following settings to start up 2.60/2.71:
UMD Select: (choose your iso, cso or --UMD DISC--)
UMD Mount: ISO ANYUMD
UMD Version: 2.xx > 2.00
Firmware: 2.60/2.71
CPU Clock: 222MHz / 111MHz (that is what I always use no problems)
Boot Select: Reboot XMB
Other: preload address: 0x88E00000
*****REMOTE CTRL: Kprintf(115kbps) (not compulsary, unless you want to use the music remote)

When selecting a UMD Disc with the UMD Select option the other settings will be changed automatically so the UMD will run, the settings can be changed back later by pressing O when DevHook is auto-starting.
