Fixing Frozen Screen After Firmware Update on Ampero Stomp II

A frozen screen post-firmware update can render the Ampero Stomp II unresponsive. To resolve this:

• Power Cycle: Turn off the device, wait a few seconds, and then power it back on.

• Safe Mode Boot: Power off the pedal, then simultaneously hold down the MENU/VALUE knob and the 2nd and 3rd foot switches before turning the power back on. This can initiate a safe mode, allowing for troubleshooting.

• Reinstall Firmware: If possible, attempt to reinstall the firmware using the official Hotone firmware update tool.

These steps can help restore functionality to your device after a problematic firmware update.
