Flashed my car back to stock so I can update the X4, but there was an error during the update and now all I see is " Device Comm Error unable to establish communication. Make sure device is operating with proper firmware." Any ideas what I can do?

If you tried to do the update wireless lyrics try plugging it into your computer and use the SCT Updater software. If you did it on the computer try wireless.

If neither work you will have to call SCT, they will have you down load a bit of software that let's them remotely access the device. I had a similar issue a couple of years ago and SCT was able to fix it remotely.

Do it on the computer and it should fix it. Mine has done it before also.
