Gaming Is it possible to update a psp without a power cable?

[ChuckBartowski]

I have a psp 2000 here, and ive been needing to update for haxx ore W/E, problem is i have no charging cable, and have been charging through USB. Is there a way to bypass the need for a charging cable?

You should be able update if your battery is charged high enough

I think you just need to have the battery at 75% if i remmeber correctly
