GTA Online – tablet and microdevice, FIB headquarters – Criminal Enterprises

The microdevice is to the right of the elevator, the location is random, and there are several, if not a dozen, locations in total – look for an open suitcase with a small device inside. The suitcase may be at the very end of the floor (on the right) in the last room where there are two FIB agents, or it may be in one of the offices that have a long table, a few chairs and a couple of laptops on the table.
