Is it constant red LED light still available after folowing this procedure (and executing sudo dmesg
):
Please check as well: “A flashing green light is a symptom of the bootloader starting followed by a reset as a result of insufficient power.” Commenting about insufficient power here just while using another USB port on your laptop/computer might/should help. Also, are you sure that used USB cable provides enough current to your Librem 5 from there used USB port, as some USB cables use higher AWG value (increasing gauge numbers denote decreasing wire diameters)?
P.S. As add-on, not even sure if Thunderbolt USB-C cables usable with Librem 5, if such cable/port connected?
