On the T-1, a factory reset is done by erasing all banks and settings:

• Run from the menu bar of T-1 Config: “Tools” → “erase banks and settings”
• The script will now erase the file system on your T-1.
• After the process is completed the T-1 will reformat with the LEDs lit in orange. This can take up to 1 minute before the reformatting is completed.

Tip: If your T-1 crashes upon startup, it might be due to a corrupt bank. Use safe-mode to check if this is the case, and use factory reset to fix the issue
