To restore your Nokia 4.2 (TA-1152) smartphone to its default factory state, you need to flash its stock firmware (flash file) from a PC. This file will remove root, virus infection, and un-brick/fix your device if it’s stuck on boot logo. Also, if there’s an issue of lag when using the device, a complete flash should fix that.
Before flashing, you should consider making a backup of your current firmware, and all other important data on your device. Flashing will completely erase your phone.
We advice that you should only flash your device if you actually know what you’re doing. You should take this information seriously, to avoid messing up your device, or turning it into a brick. It’s also important that you charge the device to at least 30%, so the process is not interrupted due to low battery.
