Hei @gdpurplefi

I’ll leave this link if you want to read and see if there is a solution in it
Updating firmware T one

Otherwise just hang in there and community support will come.

This would happen if you actually downgraded your firmware instead of upgraded.

If that is the case, you will be able to get rid of the message by going to bootloader mode (hold left button while plugging in) and doing the firmware installation again.

If that does not help, you’ll need to contact support and either get a RMA (if you’re still under warranty) or get a new unit.
