Hello I want to ask for help
Well some time ago I decided Rooting my phone (Galaxy S4 Mini) and everything was fine, in fact or not because I did not favor me absolutely nothing, now a few months ago I noticed an update, I really liked
I did everything to remove the root, as I followed the tutorials and my phone is not rooted, and App Root Checker confirms that the Root does not exist.
But I could not update my phone, no way :(
And when I go to update the software I get this:
'' THE OPERATING SYSTEM OF YOUR DEVICE changed without authorization tried to download software updates using Samsung Kies on your PC. ''
How do I do? Can I get help to upgrade my phone?
