While on final approach; shortly after passing 2;000 FT AGL; the Captain called for flaps 25. As pilot not flying I moved the flap handle to the 25 detent and we received an EICAS message; TE FLAP DISAGREE. We were at approximately 135 KTS; and the flaps stopped at just beyond 20 degrees. The Captain continued to fly and I started running the QRH checklists. We were not fully configured at 1;000 FT AGL; so the Captain initiated a go around. We were instructed by ATC to climb to 4;000 FT MSL; and were given radar vectors while we continued to run our checklists. After completion of the checklist; we discussed our options and called [Operations] to come up with a plan for the best place to recover the aircraft. Due to our longer landing distance with our flap position we decided to divert to [a suitable nearby airport]. The Captain talked with [Operations] on the SATCOM and we were given fuel burn numbers for diverting at FL230 and 190 KTS. We elected to land on the longer runway. We decided not to declare an emergency due to the long runway. We landed uneventfully and taxied to our parking spot where we turned the aircraft over to maintenance.
A B757-200 First Officer reported receiving a TE FLAP DISAGREE EICAS message on final approach. A go-around was executed; procedures run; and after consulting with Operations; a diversion plan was implemented.
