Narrative:

After we returned aircraft to the gate for a departure trip, we got a call to call the logan tower supervisor (XXXX). He said we crossed an active runway without clearance and they would take action against us. Technician YYY (left seat) and myself (right seat, radios) were called upon to take a B757 out for a power run test of #1 engine due to 2.5 bleed actuator change. Taxi instructions were as follows: taxiway a, hold short taxiway C. Amended to give way to a jetstream. Approaching taxiway C, we received further instructions. Taxiway a, taxiway K1 to taxiway B. When approaching taxiway B hold point, we were told to contact ZZZ tower (119.10). After contact with tower we were told to proceed to runway 4R dogleg for engine runup test. After successful test we were cleared to taxi taxiway a, taxiway K1, taxiway B, taxiway south, hold short of runway 9. Then cleared to cross runway 9 and runway 22R, contact ground 121.90, taxiway a to the gate, give way to company B737 before going to gate. They are accusing us of the runway incursion when we were going out and were told to switch frequencys from 121.90 to 119.10 and told to proceed to runway 4R dogleg for runup, at which time we crossed active runway 27 to get to runway 4R. At no time during the taxi did we feel we messed up and I wrote down all taxi instructions. Perhaps the ZZZ ground (121.90) should have let us hold at taxiway B hold point before switching us over to ZZZ tower (119.10). And I feel we are innocent of the accused runway incursion.
