Today when I turn on my LibreELEC, this lighting icon appears permanently and my HDD cannot be recognize. I've read that it's under-voltage. I've been using this charger for 2 years and I've never had this problem before. I have a RP3b+. Tried three different chargers all of 5.0v but still nothing. I've also updated the version to 2.6.7 as I thought it was bug but still. Thanks for your help
