Downgrading a 3.80

[feydaway]

hello, could someone help me to downgrade a 3.80 to 1.50.

i have a fat psp, and always find good guides that miss out things other guides say, so i dont know who is right.

i just need to know a few things.   do i need 2 batteries, do i need 2 psps, one already having custom firmware.

any help would be great thanks.

Hi,

First you will need a Pandora battery
that can be obtained in a few ways:
1. Soft mod:
you find someone with homebrew, he executes the 'open source pandora battery tool' and converts his battery temporary to a pandora battery. after you dont need it anymore you can convert it back to a normal battery RECCOMENDED
2. Hard mod:
You check if your battery is compatible (i dont know where a current list of compatible batteries is). then crack the case open und seperate one line of a chip. thats quite risky. your battery could be a reviewed version, you could shortcircuit something, you could damage the batterypack and expose you to that lithium metal hybrid whatdoiknow stuff.
3. buy a ready made pandora (tool) battery.
well for a one-time ting that is quite expensive i belive...

Second a magic Memorystick
that can be obtained in a few ways:
1. you find someone with a homebrew enabled PSP he executes the installer (i reccomend DC8 (despertar del Cementerio v8 that installs 5.00M33-4))
2. you find some sneaky easy installer that contains all the files on the internet.
since that contains copyrighted material you wont find it here.
with that you can make a magic stick via USB cable.

Third execution:
take everything from the PSP that is to be modded (UMD, Memory, battery)
insert the Magic stick (be shure you know how to use it DC8 boots straught away, some easy installers need special keypresses)
insert the battery. (-> the power LED turns on by itself, the MS LED starts flashing if not something is wrong
choose from the Menu what you want to isntall.
