I'm sorry, Samsung official website didn't provide the software to refresh the computer. Because there are risks, such as mobile phone problems caused by brushing your own machine, which may also affect the warranty, it is not recommended that you brush your own machine.

Supplement: 1. If the mobile phone can't be used normally due to system failure or there is a problem after the mobile phone is self-brushed, it is recommended that you send the machine to the after-sales service center, and the engineer will help you check and handle it.

2. Some brush packages provided by third-party websites or forums are unstable and have compatibility problems due to non-Samsung official original systems. If you are not a professional, it is not recommended to try to brush the machine.
