Meizu 3 is broken. How to check my previous emails?

Hello, you can press and hold the power button and volume button until the machine vibrates, and then restart. Let go when you see the sign of Meizu. At this time, connect the mobile phone to the computer, and you will recognize a storage disk. Then you can download the latest firmware and upgrade it in official website. After the upgrade, it can be started normally. You can also try this method if you can't enter the system normally due to software reasons. (Extension: firmware before flyme3.0. After entering the upgrade interface, the connected computer can read the data stored in sd. Users with broken touch screen can try to connect to the computer to back up data after entering the upgrade interface. )
