If you flash the stock ROM, you also unroot your Samsung Galaxy Tab A 9.7 at the same time. The stock firmware doesn’t come pre-rooted and unless you root it manually like you did before, you won’t be able to access root-requiring apps on your device.
There are several reasons why you may want to unroot your device. Maybe the apps are crashing too often or maybe you’re just sick of the current ROM running on your device.
Whatever the reason is, here’s how to unroot the Samsung Galaxy Tab A 9.7:
