Should your badge stop working there are three ways to fix it. Please make sure you have a backup of whatever you've been working on, you might lose all the data stored on your badge.
It's best to try these in sequence, however if you just want to factory reset your badge skip to option (3).
- Try deleting the file you have been working on, "safely eject" the badge and then press the reset button.
- Delete all other files apart from
bootstrap.py, "safely eject" the badge and then press the reset button.
- Factory reset the badge. Press and hold 'MENU' and then press the reset button on the back. Keep the MENU button held down, then release it when both the green light is on and the screen is white.
All these steps should finally get you to a screen saying "Downloading TiLDA software". It should take less than a minute until the bare badge functionalities are restored.
P.S. The micropython documentation on factory resetting is here. On the TiLDA MK3 the USR button is the MENU button, and the orange light is the screen going white.
