Brick your IQI™? Here’s the fix.

If your IQI is not working because you have tried to update your IQ-Series amplifier through the IQI, this update will get you up and running.
Just download the IQI Update Tool to your PC and follow the directions to restore your IQI to its original condition. AND REMEMBER – if you want to update the firmware in your IQ amps, connect your PC directly to the amplifier, not the IQI. Download (IQIFlashUpdater.exe)
