I have 8,4'' LTE version (SM-T705) and problem with loggining to lte.
After root imei was change and now unable to network connect. Now i cant update check at orginal firmware because i have message: unable to check, server unavainable.
I go to servis but now warranty is void and they can install new mainboard.
How to come back to orginal imei, condition?
I was unroot, load orginal firmware and that same.
