Downgrading From Version 2.6
 

Hi,
I was wondering if it was possible and safe to downgrade my software from version 2.6 to 1.5?

Can anyone help please?

at this time there is no way to downgrade a 2.6 psp to 1.5 because the gta exploit will not allow access to the flash of the psp

the way the 2.0 downgrade worked was it altered the flash to make the psp think it was 1.0 then it would let you run the 1.5 upgrade so without flash access the 2.6 cannot be downgraded
