Nokia XL is a very popular smartphone, especially in developing countries. However, this Android phone was heavily criticized for having non standard user interface. This lead to development of Nokia XL AOSP ROM and so on. Now we have a firmware that brings you vanilla android experience.
This ROM is Deodexed, Zipaligned and pre rooted, so no need to root Nokia XL again once this firmware is installed.
If you are coming from a custom Nokia XL ROM, then simply download the ROM from the link given below and install it using custom Lewa recovery. If you are from stock ROM, you must have custom recovery installed and have root permissions.
