Please help me why i can find any firmware to upgrade my phone to other versions above lollipop. Hope to get good news from you soon.
Have a nice day.
If you cant find a lollipop version upgrade for your phone it means there is no firmware upgrade release yet.
Or your phone will not be able to support newer version of firmware.
@ianblared is right I'm afraid. Most times phones stop getting support a couple Android versions after their launch.
