In the new window:

on the "PORT SETUP" menu tab (which you are on already)just select the "Serial COM Port" (you need to choose the one that says that is your 3G Application Interface, not the one that says PC UI Interface whatever the COM Port), then select the "baud speed" (This varies depending on the computer speed and windows OS, default speed is 115200), and thats all you have to do for the setup menu tab. Next go to the (2) "DIAG Port (QC)" menu tab and click on (3) "send" this should now show some numbers on the open space box below, On the 'Diag Functions box' (box below the "send" button box) you wanna select (4) "Read EFS" instead of Save memory to file then tick (5) "Alternative Method" then on (6) "max page" type: 200 , then click (7) "lets go", this will ask you to save a file so just save file as E583C_yourebayid onto desktop ( file size is appox 300kb)
