9300 How to completely unroot one click Root

You can go to the forum to find the post to swipe the machine. It's cumbersome. To flash a software, clear it.

Because every time you root, there is a counter in the coal digging mode that is turned on. Therefore, it makes no sense to simply brush the official firmware, and the after-sales will check it. I've been mixing in the Witty forums.

I remember looking for this post once last year. You can search for root for yourself.

Hello dear Samsung users:

According to your description, you can access and modify almost all files in the phone's operating system by obtaining root access through third-party software, but this operation may affect the stability of the phone, and there will be artificial failures such as crashes and restarts. In addition, after obtaining permissions, it usually causes problems to major components of the motherboard, such as memory and CPU. Root is a modification of the operating system software, and according to the regulations, it does not belong to the scope of the warranty.

In order to improve customer satisfaction, Samsung provides free firmware upgrade service to root customers, and if the root has affected the hardware of the mobile phone and needs to replace the motherboard, the motherboard fee will be charged. If you need to restore your machine to the original system version after rooting, please send your machine to a Samsung service center for after-sales engineers to help check and process. It is not possible to unroot the device by resetting the device to factory settings by yourself.
