Narrative:
As we entered georgetown airspace we lost both left and right weather radar. Captain used emergency authority to reset weather circuit breakers at maintenance control suggestion to no effect. We flew around weather in vicinity with the aid of nearby aircraft. In the course of the next 45 minutes; there were several altitude and routing requests which involved four control areas. With the poor quality of the radios and the language issues; there were concerns about confusion between us and controlling agencies. We experienced no loss of separation or adverse weather encounters. We were recleared on a weather safe route suggested by our dispatch and the remainder of flight was uneventful.
