Or have you tried a factory reset and then updating firmware? > [@Reset to factory settings?](https://forum.snapmaker.com/t/reset-to-factory-settings/23058/3): > > To perform a **Full Factory Reset** to the currently installed version of firmware, you need to **Factory Reset** both the **Touch Pad** and the **Controller** : > > 1. Connect your computer to the **Controller** via USB (must be USB). > 2. Issue an `M502` factory reset to the **Controller**. > 3. Put the **Touch Pad** into **Developer Mode**. This is done via the **About** page, and tapping the printer image 5 times. You’ll see a popup window when it changes modes. > 4. Reset and clear out the **Touch Pad**. You will need to navigate around to find this, as it seems to change with each version of firmware. > 5. Reinstall the currently installed version of firmware from a USB drive (must be from a USB drive). All versions of the firmware are available in the [Snapmaker 2.0 Firmware Updates and Downloads](https://forum.snapmaker.com/t/snapmaker-2-0-firmware-updates-and-downloads/5443) thread. > 6. Update all of the modules. -S --- _[View the full topic](https://forum.snapmaker.com/t/a350-will-not-connect-after-an-interrupted-firmware-update/32604)._
