I just tried the 55 IU EXT downloaded from here http://www.coolhawk.com/gsmhawk/5510-UI-DSP.zip and computer don`t found phone (error: Fail to communicate with EXT_UI board!). I try to flash with Fbus cable and when i got no sucess then i tried to interchange rx and tx but anyway the error ir the same... Maybe this package ist`t right... Where i can download some other version of 55 IU EXT??
