I have an e-series electron but it doesn’t blink yellow, will they have any help for this?



What device OS version?
How have you tried to enable DFU Mode?


I sent the firmware through the flash and loaded version 1.2.1
I tried to enable DFU Mode pressing the reset and mode button, and released the button reset.
