I have 3 GX440s verizon, actually I have about 20, but three of them are having similar problems.
The power light goes green and stays on, but nothing else. I can log in and have attempted firm ware upgrades, but cannot seem to get past 4.3.3.014.
I have swapped sim cards x 2 with no change. I’ve done resets and reboots. There is no radio activity on either wifi or wwan.
Any thoughts or help would be appreciated.
