I have a sprint galaxy tab 3 and I atempted to root the device the other night and obviously it did not work I do not have root access and now I can not do OTA updates because it says that my device has been modified. Also I have a constant notification that says preparing network yet I have full access to 4G and wifi. I have already dome the steps to get rid of this notification yet not of them worked and its slightly annoying with a check mark lingering up top. If anyone can help me either restore my tab to stock, complete the root or even get rid of this notification permanently that would be amazing thank you very much.
