I just upgraded an original (unused) OnlyKey to the Beta 7 standard firmware using Teensy.
It worked, but when I opened the Desktop app to do the initial configuration, it asked me to upgrade the firmware again (that was the only tab showing), so I did, but then it got stuck with the LED in bright white and showed the “Please connect your OnlyKey” message for over a minute.
I disconnected and reconnected the OnlyKey, the Windows OS plays the “deviced connected” sound and Teensy continues to recognize it, but the app keeps showing the “Please connect your OnlyKey”, and the LEDs stopped working.
I tried loading the Beta 6 firmware version with Teensy, but still no LEDs are flashing and the app does not recognize it.
Any help is greatly appreciated.
