Narrative:

During our pre-takeoff briefing; the captain; who was to be the flying pilot briefed that we would conduct a flaps 20 takeoff. Upon nearing our turn for takeoff; the captain called for the 'flaps 8 before takeoff checklist'. I executed and we confirmed the 'flaps 8 before takeoff checklist' using the challenge and response method. Our EICAS displayed a 'takeoff config ok' message which we confirmed upon being cleared for takeoff in the 'takeoff checklist'. During the beginning of our takeoff roll I noticed that although the EICAS displayed a 'takeoff config ok' message; our ACARS was flashing a 'set flaps' message. Due to this conflict I called for an immediate abort. The captain safely stopped the aircraft. I notified the tower that we had aborted; there was no emergency; did not need assistance; and that we would be exiting the runway with the intent to be re-sequenced for takeoff. There were no injuries to the passengers; no damage to the aircraft; nor was there any damage to other property. We were re-sequenced and departed without issue after notifying our dispatcher and receiving a re-validation of our release.
