Nokia 7 Plus official firmware: how to flash



Updated: June 25, 2024

Nokia 7 Plus official firmware restores your phone to its default factory state after successful installation. The firmware removes root access (unroot), eliminates virus infection, and repairs your device if it’s stuck on boot logo. Also, if the phone lags, after flashing it should function better.

Additionally, you should consider making a backup of your current firmware, and all other important data on your phone. Flashing will completely erase your phone. So, you should only flash your device if you actually know what you’re doing; to avoid messing up your device, or turning it into a brick.

It’s also important that the device battery is charged to at least 30%, so the process is not interrupted due to low battery.
