Narrative:

Approximately 1 hour elapsed flight time at XA15, first officer and I were working out a bleed air problem with dispatch and technician, when we received a saaru (backup standby att reference unit to adiru) status message along with a 'no land #3' EICAS message, and an amber 'att' (symbol that replaces the 'glass' standby attitude indicator, not available) box in place of the standby attitude indicator. In complete corporation and coordination with technician, the relief pilot attempted to restore the saaru (backup standby att reference unit to adiru) in the east&east compartment, unsuccessfully. Decided to divert to ZZZ1. Declared an emergency, and with the advice of dispatch dumped fuel to maximum landing weight. Normal landing at ZZZ1. Note: kudos to relief pilot and extra relief pilot for efforts above and beyond, and also, an outstanding job by our entire flight attendant crew. Callback conversation with reporter revealed the following information: decision made by all participants to divert to ZZZ1. Reporter stated that there was no way that the flight could proceed on a 12 hour flight over the northwest territories and polar rtes with the lack of a standby attitude indicator and backup navigation and instrument display system. The bleed air problem was a repeat item that was not fixed with the repairs made prior to departure. The aircraft was turned over to maintenance, another aircraft was used with a new crew after a 3 hour delay. Reporting crew and flight attendants went off schedule, deadheading home. Reporter stated that this was his first 'solo' trip after completing his IOE on the B777.
