Angry 8500ci Plus Firmware Update Issue

Hello Everyone,

I have been having difficulty trying to update the firmware on my 8500ci Plus.

The first part of the update appears to work fine (using the "Update All" function on the advanced settings tab) and then the 2nd stage displays the following error message:

"Unable to remove older version"

Has anyone seen this before?

I have tried the update with the latest Detector Tools on Mac OS X and Windows 8.1, the results are the same.

In addition, I did a factory reset and still the same error message.

Thank you in advance!

Default Anyone out there from Escort?

Wanted to see if someone from Escort might be able to help with this issue? Or should I call customer support directly?

Make sure the system is powered off when you update it (which is not true for our other products). Other than that it should update without errors. If you continue to receive an error message then please contact our service department at the number in my signature below.

Escort Radar customer service is available from 9am-5:00pm Eastern Time Mon-Fri at 1-800-543-1608 or you can fill out a repair form and we will contact you.
