Issue description: Inch Duo is in booting stage and the reboot of the station doesn't help.
Sometimes this happens due to voltage fluctuations on the motherboard. The SOM then becomes corrupted and stays in boot loop, so it needs to be replaced.
To prevent the voltage fluctuations we recommend replacing the motherboard (H-1029-A), a guide how to replace the motherboard in INCH Duo can be found here: https://etrelchargingsolutions.atlassian.net/wiki/spaces/TSFP/pages/3924838004.

Install PCB spacers on motherboard and align new SOM with PCB spacers and multi pin connectors on motherboard.
