hi fraser, for now, i would recommend making a copy of /etc/reachview/current_config.json
cp current_config.json current_config.json.backup
if red led occurs, just copy the backup to original file again and reboot;
according to Red LED on Reach, where is the log file for the error? - #4 by savvy0816
@dicky i’m afraid you will have to reflash your device again…
