Narrative:
Aircraft returned to gate with logbook page item 1 'engine 2 hp valve low pressure at idle.' customer service said the flight crew would be ineligible to continue in 30 mins. 2 mechanics did the mechanical lockout procedure per MEL 36-1107A. Myself and another mechanic did the logbook. Per the MEL, I pulled circuit breakers D12, D11, Z22 and Z23. My partner installed the 'inoperative' sticker in the cockpit and I finished the logbook entry. I handed the logbook into the crowded cockpit and we dispatched the aircraft to ZZZ1. Back in the office, neither my partner nor I could recall resetting the circuit breakers.
