Could you please clarify:
- When you say “could not connect” do you mean the radio could not register on the network? Or, could not establish a data session?
- Could you confirm you SIM is active with the proper LTE technologies?
- Could you confirm your APN is correct for your SIM?
Let’s try an FX30 factory reset. Power off your device. Press and hold the reset button, apply power while holding the button for another 10-12 seconds.
If you ssh to 192.168.2.2 and you’re prompted to create a new password, you know the factory reset has occurred properly.
Regarding the firmware update, could you please try fdt2 using a Windows machine to install the full image, if the factory reset doesn’t work?
