In the event of System errors, software corruption, or display issues, recovery firmware can be applied as a final troubleshooting step. By running the recovery program, the Compressor will be defaulted and reverted to an older version of its firmware, resolving most operational issues. Once the recovery is complete, the system can be upgraded back to the latest release.
This firmware recovery guide is intended for users who encounter system startup failure or experiencing symptoms of file system corruption.
Note: It is recommended to avoid the use of Kingston and San Disk brand USB sticks, as the Compressor may experience an issue while allocating the firmware files from the USB.
