i am actually stuck on that with needing decking 6 i really dont want to start the mission over to

Thats what I had to do. Restart and take your rigger with you. I have found no other way.

Berkeley doesn't require a rigger or decker, I just finished it without either one!
To disable the cameras you don't need drone control 6, you can just destroy them by starting combat and attacking them.
To destroy the machine you don't need decking 6, just go to the top floor of the last building and use the console in the very first room you enter.
