Histórico de "How to fix lens error"

ive tried the standard troubleshooting. i.e. taking a piece a paper and sliding it around each level of the lens barrel. using pressurized air to force debris  out to no avail. My next step was to open it up, but since this is my first time dealing with cameras ( normally work on destops) I wanted some advise.
