My LTE extender will not switch to OPEN. It is stuck on Closed and when I try to select OPEN I get an error message ("Your changes cannot be saved due to system error. Please try again later")
The problem is, when I try to add numbers to my LIST is also gives me an error message. After trying to add a number to the LIST it gave me an error message and seems to have deleted my other numbers.
Now, with the device in CLOSED mode and no names being able to be added to the LIST, it is basically a brick.
Any thoughts?
