I'm very sorry, but the official website of Samsung mobile phones does not provide flashing software. Due to the risks associated with flashing, such as mobile phone problems caused by self-flashing, it may also affect the repair, so we do not recommend that you flash your phone by yourself.

If the mobile phone cannot be used normally due to system failure or causes problems with the mobile phone after flashing the phone by itself, it is recommended that you send the machine to the after-sales service center for the help of the engineer to check and deal with it.

Supplements: 1. Some third-party** or the flashing package provided by the forum, due to the non-Samsung official original system, there are instability and compatibility problems, if you are not a professional, it is not recommended to try to flash the machine.

2. In order to make users have a better experience, Samsung mobile phones provide system update services, if there is a new firmware, there will be a push update notification. You can do the following: Settings - (About Phone About Device) - System Update - Automatic Update - On.

What phone? If you are a rookie, it is best not to brush it yourself, it is easy to brush into bricks.
