Hi there.
Did you look on the Celestron site?

The hand control of my new scope shows the message “Bootloader invalid package 0080” or “Bootloader invalid package 0002”. How can I fix this and make the mount work?

Sorry if you already had this information.
There are quite a few hits come up from a Google of that Error. Seems pretty common for some reason.
