Maybe, But thought the more experienced on here would know?
I upgraded the original firmware to the latest last release, then rockbox'd his ass lol.
I will rockbox my son's without updating original firmware and see if it is that causing the issue.
Any views on this?
UPDATE AFTER THIS ABOVE POST:-
I connected player via usb and started EASEUS partition master home edition in order to format the player, of which i did as i never trust window own format.
Then i safely disconnected the usb and message came up asking to connect to usb, of which i did, the screen then shown Bootloader USB
I then proceeded to run the ROCKBOX UTILITY and start flash again.
Now the player loads much faster, No slowness, music playing well, no freezing, which would have been doing so if i had left it.
I will leave 2 days of playing and come back so i know for sure this method i chose worked.
Best wishes
