2.60->1.50 without pandora battery. Flash dump help plz

[S6A6T6A6N]

My friend's got a psp he wants to downgrade from 2.60->1.50
I searched around and it said that you need some program that is copied from a 1.50.
Nobody that we know has a 1.50... however we do have Dark Alex Custom firmwares. So can we use the Dark Alex firmwares to obtain the 1.50 flash dump?
Thanks.

Please upgrade to 2.71 first.
Rename EBOOT_271.PBP to EBOOT.PBP
Then Put it into folder PSP\GAME\UPDATE :
Go to memstick,there will be folders PSP,VIDEO,MUSIC.Go into PSP.
Go into GAME folder after you go into PSP.
Create a folder UPDATE,it has to be all capital letter.
Then put the EBOOT.PBP into the UPDATE folder.

If you successfully downgraded then congratulations and tell me how it goes.
Do you want me to tell you how to upgrade to custom firmware?
I'm here to help!

 

[S6A6T6A6N]

Yea... we cant do it yet because his psp is on low power. And we're still not sure how to upgrade to custom... thanks again.

 

[dennis96411]

I don't see why going through the trouble of downgrading using old downgraders when you can simply make a "magic" stick and pandora bettery considering you have acess to cfw installed psps.

 

[dennis96411]

Dude he got a 2.60 official before he downgraded, he can't change it with that psp.
