UpRev FATAL FLASH ERROR | Any ideas?

NissanTracker · 07-10-2018, 07:28 PM

Ever since updating UpRev, I have been having connectivity issues with my ECU. I called in and support mentioned disabling any firewall/anti-virus. I actually did not have anything running. I uninstalled UpRev and removed the driver from device manager.

After re-installing, I was connecting again. Then I updated UpRev as it had asked. I started again with connection problems. Uninstalled and refused the update the next time. Was running fine up until I got a flash from my tuner and it failed in the middle. FATAL FLASH ERROR

Fans on the car are constantly on. I am able to reconnect, but VIN number does not show up. When trying to flash, it warns me about losing a license. Even accepting this, does not flash.

This connectivity issues happens on all 3 of my laptops. Sometimes it just hangs on "Checking ISO". Will stop randomly logging. Can't clear CEL codes... will state "Clearing" and will just hang indefinitely.

Any ideas?
