Someone Suggested that:
Turbo sim should be taken-off while executing query in Mobile Terminal. I say this because our 3G kept rebooting before I could get my eyes on the results. Only after taking off the turbo sim and leaving carrier sim, could we capture a snapshot of the results.

After installation, run the WinSCP available in Start menu under Programs.
Step 2

Then hit the Login button

Step 5
Select BBUpdaterExtreme file from left pane and drag it to the right pane (/bin)
Step 6

Step 7
