M7350 stuck on 'Connecting'
My M7350 has been working well for many months but recently it randomly stopped working without any interference from me. After turning it off and on again it would not connect to the 4G or 3G network. It will just display the message 'Connecting' indefinitely. It still responds to button inputs but will not start the WiFi hotspot and so I cannot connect the web-management page. I have used the SIM card in this device for many months without significant problems and it still works when I transfer to another device. I have also tested another working SIM in the M7350 with the same results. I have turned the M7350 off and on again and also reset the device several times with no change.
Is there anything else which can be done?
