fat psp unbrick using slim psp CFW 3.90 ?

people, if you do not know, do not answer.

yes, have your friend turn your battery into a pandora.

once youve unbricked, have him restore your battery

no, gui will not help.

you need to use the despertar cementerio to make the magic mem stick.

Unfortunately, a slim Pandora Battery wont work on your phat PSP.

if your friend has a 3.90m33 custom firmware, you should get a slim tool battery from datel, so you don't mess up your friend's battery

I found this, try to see what works best for you two:
