I downloaded and updated the firmware from your firmware link that says newest version. I show it updated to 1.17.03, however I am seeing posts stating there is a 1.19 version. Did I download from the wrong link?
Currently, 1.17.03 is the most recent firmware available for download through Surety. While 1.19 should be available soon, there is no ETA just yet when it will be posted. 1.19 is available for OTA update however. Release notes on 1.19 can be found here.
