Here are the early preparations:

Make sure that your device is exactly as mentioned above. To check out what device you have, go to Settings > More/General > About Device or Settings > About Device and match the model number. Be careful about the device model number, flashing a file on a device not listed here might result in bricking it up.

2. Battery should be charged at least 60%!

Your device’s battery shouldn’t be weak. In case your device goes dead during the flashing process, your device may get soft bricked and you might be in need of flashing stock firmware and that will ultimately result in wiping up your data as well. So, make sure that you charge your device before you start the flashing process.

Always use the original data cable to establish connection between your Android device and your computer / laptop. Using ordinary data cables might interrupt the flashing process, so to avoid any mishap, you need to meet this requirement as well.

4. Enable USB debugging

Your phone must have the USB debugging enabled. In order to enable it, go to Settings > About device > tap the build number for 7 times. The developer options will be enabled, now go back to the menu screen in settings and open developer options. Once opened, enable USB debugging from within the developer options.

5. Backup everything!
