just go to youtube and search.i used this one to downgrade mine so it must be good:=-fHri9JJH-I
good luck
FYI:u need a pandora battery (instructions also given on youtube) and a magic mem stick(u know where to look)
Here is what you need:Pandora Battery and a magic memory stick.
It is not possible if you have a slim, but if you have the old one your friend can have either one.THE PSP WITH 3.90 m33-3 must be a phat.
1) First download this file.
2) Then download this file
3) Okay here is where it gets tricky, go into the first download there should be two folders, you see the folders, seplugins and 3.95 gen docs, dont pay any attention to them at all.
4) Go inside the psp folder, there should be a folder called game in there. Go inside game, there should be another folder called update. Go inside that.
5) Once your inside update, there should be a file called eboot.pbp. Dont touch that.
6) Now go into the 2nd download. There should be another eboot.pbp. rename it to 395.pbp
7) Put the 395.pbp into the update folder with the eboot.pbp
Now drag and drop the UPDATE folder into PSP, Game on your psp memory stick. (turn your psp on to usb mode, on the computer it should show your psp, in the root of your memory stick, the starting place you should see a couple folders, PSP, MUSIC, VIDEO ect. drag the psp folder with the UPDATE folder in it into the root, overwrite all files. It should look like this. PSP,GAME,UPDATE, 395.pbp and eboot.pbp)
9.) (just a reminder you should be doing this and the already custom firmware psp) Take your psp out of usb mode. Then go into the game icon then memory stick and click x
10) There should be an icon that says 3.95 gen update. Click x
11) Follow the installer on the cfw(custom firmware psp)
12) okay once you have that installed turn off your psp completely
13) Now hold the r button and turn on your psp. There should be a menu. Go to advanced.
14) Go to create pandora battery, press x.
15) Now this is a little crazy. You now have your pandora battery. Dont worry you can always turn it back into a regular one, just go back into the menu that created it and then select make it normal. Connect your psp to the power cord, and take out the pandora battery.
16) your psp should have no battery in it and it still turns on. Go into usb mode.
17)Now download this file
18)Now download this file
19) Inside the first download there should be a folder called DC7 Put that into PSP, GAME, where the update folder is.
20) On the other download rename it to 401.pbp, put it in the root, where the PSP folder is.
21) On your psp go into game and memory stick.
22) Go the Depertar del cementario v 7
23) Run that.
24) If it asks you to to select a button just hold left trigger, so that when you put in the pandora battery and hold L this program will come up.
25) On your friends psp put in your memory stick
26) Hold L while putting in the battery, it should turn on by itself.
27) Press x and install 4.01 m33-2.
28)When that is done your friends psp should have custom firmware.
29) Dont worry you can always turn it back into a regular one, just go back into the menu that created it and then select make it normal.
Wow, all of these answers are wrong so far…First you need to find magic memory stick files online. Find those using google/yahoo.Put those files on a formatted memory stick. Then use pandora battery creator (homebrew file) by putting in an extra battery and running the program it will make a pandora battery. Now all you have to do is insert the magic memory stick into his psp. Then insert the pandora battery into his PSP and now he has custom firmware.
Hope I helped,
