After a full code install from USB finishes, the game restarts, shows 'game code update resuming', then keeps rebooting through the Stern logo (with a crackle from the speakers each time) and never gets further.

Code update stuck in a 'game code update resuming' reboot loop: re-download and reinstall

Cause: The update had not taken: the files on the USB drive were bad.

Checks

• Power the game off, remove the USB drive and power on again: it should boot on the old code.
• If a QR scanner is fitted and the game keeps rebooting, unplug the scanner to rule it out.

Fix

• Delete the downloaded update files, download them again, copy them to the USB drive and run the install again.
• If it still fails, re-image or replace the SD card with the image from Stern support.

Systems

• Spike 2

Games

• Iron Maiden: Legacy of the Beast (Pro)
