Nubia z5S flashing

Flashing refers to the process of installing firmware or an operating system onto a device. In the context of an Android smartphone like the Nubia Z5S, flashing typically involves replacing the device's existing firmware with a custom version of the firmware or with a completely different operating system, such as CyanogenMod or LineageOS.
Flashing can be useful for a variety of reasons. For example, flashing a custom firmware can give you access to additional features or settings that are not available on the stock firmware. Or if your phone has a hardware issue and can't be fixed by regular reset or software update, flasing to original firmware can restore the phone's functionality.
However, flashing can also be risky if not done correctly, as it can permanently damage the device or cause it to stop working altogether. It's important to research the specific firmware or operating system you plan to flash and make sure that it is compatible with your device. Additionally, you'll need to backup your data before proceeding flashing process.
You also may have to have unlocked bootloader, also some specific software like flashtools and drivers installed in your computer.
It is recommended to follow the instructions provided by the firmware developer or follow the steps provided in a tutorial specifically for the Nubia Z5S.
