Samsung SM-T707A Firmware Update Availability Through AT&T Servers
I performed a factory reset on a Samsung Galaxy Tab SM-T707A which is now only being used as a WIFI device. The plan was to run firmware upgrades after that, but I am getting a message the device is already on the latest firmware version which is the stock firmware now.
I thought those updates could be obtained from Samsung as well, but it looks like they are only available from AT&T. Do I have to be an AT&T subscriber to be able to receive firmware updates for my device? I have switched to another carrier, so I am not with AT&T anymore.
