This is the most practical method for many technicians. While the exact schematic for the OSAMU2 board is not available, a closely related model—the —is known to be extremely similar. This board shares the same core components, particularly the primary power management chips. In complex repair scenarios, expert technicians often use the NM-A804 schematic as a reference to reverse-engineer and interpret the signals on the OSAMU2 board.
