Hello. Blue TEF without a download button, I can’t flash it. When you press start on the keyboard and then turn on the receiver, it plays, the firmware does not work. The question is when should the receiver be turned on when flashing the firmware immediately or later during the operation.
1. If you could not tune when bought from new, then return it for a refund or replacement 2. If it does not tune because of a firmware update, try re-flashing to another firmware version 3. Join the TEF Discord group & ask there as it is the best place for questions on this radio
