How to flash the Nokia G42 official firmware?

The firmware is designed to be flashed to the phone under fastboot mode. So, first of all, put the phone in fastboot mode. You can do so by turning off the phone and pressing and holding the Volume Down and Power Buttons together. The phone will restart to fastboot mode.

Now, check the bootloader state of your Nokia G42. Look for the details after the entry “Device state –” in the fastboot screen. It will be either locked or unlocked. Follow the relevant option below as per your device’s state.

If the bootloader is unlocked (device state: unlocked)

Download the firmware file.
Extract all files within the romAll.zip file inside the firmware zip file.
Use Android Platform Tools (Minimal ADB and Fastboot) to flash all the images to the phone. For example:
fastboot flash abl_a abl.elf fastboot flash boot_a boot.img
And so on…
Finally, set slot a as the active slot and reboot the phone:
fastboot set_active a fastboot reboot
