Before doing anything else, watch this video first, it will clarify pretty much everything. # Check First *** Before you start, it's crucial to be aware of the following when recovering from an error: - **USB Cables\:** Check that they work and firmly connected. The best way to test is to connect your controller directly to your PC or console and see if it detects correctly. - **No Scripts or GamePacks\:** Ensure no Scripts or GamePacks are loaded. Why? Because sometimes, these can be the cause behind the fault you’re wrestling with. If you find a script or GamePack causing havoc, give a shout out to its creator to get any bugs squashed. - **Protect Your MK Profiles\:** Ensure that all MK profiles are securely backed up, to avoid losing any of your tailored settings. - **Script Safeguarding**\: Unfortunately, scripts cannot be backed up directly. Ensure that you retain a separate copy of any script you've been utilizing to avoid any potential gaming disruptions. OK, let's get after it.... ![](https://api.archbee.com/api/optimize/IwUlH55FdaPsVELSqm1Fc/77tE7xrp73S7wZkyKNKwd_image.png "Cronus Zen - CONSOLE/PC USB Cable to PC") Here's the complete list of firmware errors and verified solutions. # No Devices Found *** This error usually happens due using the wrong USB port, or a faulty USB cable. Here's a list of proven solutions. If these don't resolve the issue, it might be best to get a replacement. 1. Ensure the USB cable is good and plugged into the correct `CONSOLE/PC` USB port. 2. Test with a different USB cable; yours might be faulty. 3. If your PC USB port isn't supplying enough power, use a [powered USB hub](https://cronus.shop/collections/cronus-zen/products/cronus-mk-switch). 4.
