I unlocked one T639 (in freeze state) with Easy Unlocker Box, try to read codes first. If you canīt read codes try use direct unlock, select model as Samsung Z240 (itīs very similar)
.....
PD: if you have freeze phone state use the option for un-freeze, everytime select z240 model...use e210 cable!!!
Sorry for my english!!!! i am from Uruguay....
100% WORKS!!! POST RESULTS.
Regards to EU Box Team, good works!!!!
