NOTICE:
I TAKE NO RESPONSIBILITY FOR ANY DAMAGE OR 'BRICKING' THIS GUIDE MIGHT DO TO YOUR PSP, BATTERY, MEMORY STICK, PC made by gameunreal

Requirements:

1-A normal (fat) psp running custom firmware or the original 1.5 firmware.
2-A battery that is compatible with Pandora( see my compatibility thread) http://www.pspmod.com/forums/firmware/2166...ility-list.html (Pandora's Batery Compatibility list)
3-Memory Stick Pro duo, (MS Duo's won't work, so the stock 32 mb card won't work). Any other card, 64mb up to 4mb will work.

FILES YOU NEED:

- 3.60M33 Custom Firmware: http://dl.WE TRY TO STEAL PSP-SPOT STAFF/M33-PSP-Slim-Custom-Firmw...14521/catid/114
- Download Official 3.40 and 3.50 Updates here: http://www.psp-hacks.com/file/1130 and here: http://www.psp-hacks.com/file/1164


INSTALLATION:
1)Use this guide to create a Pandora's Battery and Magic Memory stick: http://WE TRY TO STEAL PSP-SPOT STAFF.WE TRY TO STEAL PSP-SPOT STAFF/Tutorial-How-to-u...g/49/aid/100693

2)Once you have a funcional Pandora's Battery and Magic Memory stick ( the FAT psp boots into service mode when you insert the battery with the memory stick already inserted.)

3)Extract the 3.60M33 Custom firmware archive.

4)Run the fat psp with the Magic MS inserted but WITH A NORMAL BATTERY.

5)Select USB mode on the fat psp and from inside the archive you just extracted copy pandora_slim and pandora_slim% to PSP/GAME, or if your
1.5kernel is set to game150, PSP/GAME150 (by default it is set to PSP/GAME, but you can check in Recoverymode->Configuration->1.5kernel folder)

6)Extract "EBOOT.PBP" from the 3.40 and 3.50 update packages you downloaded and rename them "340.PBP" and "350.PBP", then copy them to the "pandora_slim" folder you just copied to the PSP.

7)Run the program you just copied on the fat PSP (pandora-slim creater).

8)Insert the Magic Memory stick and then the pandora battery into the slim. The green light will turn on, but the screen will not, THIS IS NORMAL: DO NOT PRESS ANY BUTTONS

9)To install press X, ONCE. Wait until the green battery light turns off. this should only take a few seconds, as you are only copying a few custom prxes and team m33's custom ipl.

10)Break open a beer and pat yourself on the back: you slim psp is now homebrew compatible!!
Other Stuff

There is no permanent unbricker for the psp slim, only the usual recovery mode, so be careful when you mess in the flash.
Not all homebrew will work as the 1.5 kernel can not run on the PSP
