[Jomapika]

hello,

i am gonna update my ps4 from 3.50 to 4.01 via usb

the problem its i have downloaded on ps4 the update 4.05 (yeah it was automatic download but not to install, so everything its cool) can i delete since its using my HDD space and dont need it?

and if there is a problem and will mess with usb update if i have the 4.05 on the HDD?
