Hi guys,
I have issue that my CLUE stopped being recognized as Adafruit CLUE, i probably uploaded bad sketch from Arduino ide.
Before it was working all fine and detected fine as Adafruit CLUE, Port 5 on Windows 10
Once I uploaded sketchy sketch it stopped being recognized.

BUT when I do double tap on reset it turns into Adafruit Feather nRF52840 and Flash drive showing as FEATHER840 and I can upload stuff but as Feather 52840 and Port 7. Which is bizarre ! What is this about?
So how can I get it back into Adafruit Clue ?

Hitting reset once just keeps running Blinky ( uploaded as Feather board in previous step ) but board it not detected by any Windows !

Please help

Tried also on Windows 7 same story.

Windows 10, Arduino IDE 1.8.19, 16Gb Ram, i5 Cpu
Windows 7, Arduino IDE 1.8.19, 32Gb Ram, i7 Cpu

You are doing the right thing with the double tap 'reset' and getting into bootloader mode.

Your PC is still recognizing the bootloader USB drive name and just seeing the device on the next available COM port. You should not be concerned about the bootloader drive name or COM port switch.

Thank you @mikeysklar
Sure, it still sort of works. But before it was USB accessible right after regular single reset, but not anymore.
Do you know if there is a way of hardware resetting it back to how it was ?
Reflash bootloader perhaps?

Good work getting the bootloader installed. Glad to hear it resolved the programming issue.
