Anyone having issues with firmware version 1.0.4 ? The device becomes a fancy brick. Had to downgrade to 1.0.3.

how do I update firmware via CLI, serial console ?

Thanks Daniel. 1.0.5 works fine. Ish. I still have problems and lack of trust with this device. It burned 5V USB-C devices before, by sending them much higher voltage. And now says that battery health is 79%. Support told me that I can't get replacement anytime soon, due to demand. So I keep on reserving it for soldering only. Otherwise I have zero trust in this device, just wish iFix it team did better. Put it this way, if this was apple - they would have slaughtered it for what I experienced.
