downgrading help

[hellraizer]

Hi, my friend has updated an already downgraded 1.5 psp, is it possible to downgrade again, many thanks in advance for any help

what version did he update it to?

[hellraizer]

firmware 2.6

[Axelius]

Then there's no problem. Just update to 2.80 and use the 2.80 downgrader.

BTW: Yes, I know there is even a downgrader from 2.60, but the 2.80 downgrader is a lot safer.
