This worked for me when the reset trick refused to.It is possible when using the USB board. You just have to go about it in a different manner.1. Take the module out of the interface board.2. Connect the interface board to the computer.3. Open X-CTU4. Go to "Modem Configuration"5. Put a check in the "Always update firmware" box6. Select proper modem from drop down menu,7. Select proper function set and firmware versionfrom drop down menus.8. Click on the "Write" button. After a few seconds oftrying to read the modem, you will get an Info boxthat says Action Needed. At this point, CAREFULLYinsert the module into the interface board.9. You may get the info box again a short while after,just use the reset button on the interface board.This should get you back up and running.It can take a couple of tries but it worked for me.
