Lenovo A789 how to revert to uncracked after cracking

Obtaining root access through third-party software can access and modify almost all files in the phone's operating system, 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.

Therefore, it is not recommended to root, otherwise it is easy to bring serious consequences, and the hardware problems caused by root are not guaranteed, please understand.
