My CCGX has worked fine for 5 years together with two MPPT 100/50 BlueSolar charge controllers and Phoenix Inverter 12/3000/230, with the latest firmware v. 2.0.6. Some time ago it started booting on its own, without any external reasons. Suspecting firmware problem, I downloaded the latest firmware 2.3.3 to a micro-sd card and followed the procedure given in the manual (with LAN and VE cables disconnected). The software update went fine, but the device does not boot up properly, it remains in the blue page with Victron logo. What to do?
