There is no BB8000. Perhaps it is a 9000?
See the FAQ for the two articles on Jl_Cmdr. one on how to wipe, the other on what to do if it doesn't connect.

Go to the yellow sticky at the top of the 9000 section (if it is indeed a BB 9000) and get the latest OS and the instructions for installing. Follow them exactly and be patient.
