First of all u need a cfw. to get that u need a pandora's battery and a magic memory stick. How to make that? well here's a guide for firmwares 1.50 to 3.60here Full credit goes to lounger for this guide.

PART 1: Create a pandoras battery and magic memory.

REQUIREMENTS
- A spare PSP Battery.Using a spare is best, as it
will not be possible to boot the PSP in its normal state with the
modified battery.
- A spare Memory Stick Pro Duo of less than 4Gb. (256Mb should be
enough for all applications).
- A PSP with a Custom Firmware, or a PSP with
the 1.5 original kernel.

1. Download the files from the links given in the tutorial.

2.Connect the PSP to the PC with the Memory Stick inside via the USB
Connection.

3.Use mspformat to format the Memory Stick logically.

4.Remove the Memory Stick and disable the USB connection.

5.Connect the Memory Stick again via the USB connection of the PSP

6.Manually create the PSP/GAME (optionally PSP/GAME150) folders on the Memory Stick.

7.Copy the "battery" and "installer" programs to the PSP/GAME
(optionally PSP/GAME150) folder.

8.Copy the 1.50 official updater as UPDATE.PBP to the root of the
Memory Stick.

9.Remove the Memory Stick and disable the USB connection.

10.Run "installer" through the firmware on the PSP. This application
will create the firmware files on the root of the Memory Stick, as
well as msipl.bin.

11.Connect the Memory Stick again via the USB connection of the PSP.

12.Execute "msipl" application on the PC with the msipl.bin to write
the IPL to memory stick.

13.Remove the Memory Stick and disable the USB connection

14.Execute "battery" application on the PSP to modify the battery.

Congratulations, you are now in posession of a "Magic Memory Stick"
and a "JigKick Battery".

PART 2: Using them to mod your psp.

1. Insert Memory Stick into the PSP
2. Remove power cord and insert the JigKick Battery into the PSP.
3. A menu appears when the PSP boots. Follow the onscreen information
and instructions.

Credit goes to Dark_alex for the cfw, and to me for this guide ;)
