Recover Firmware

The following section goes into detail of the firmware recovery process for Mango when it does not boot any further than U-Boot. This can happen during an accidental shutdown during the firmware upgrade process or any corrupted system files. Some recovery methods will require LAN and serial access. Note: any configuration changes made previously will be cleared!
