I own a LG G Pro Lite which came with default android version 4.4.2 (Kitkat)
sometime back, it was upgraded to lollypop and was working fine.
Recently I had to reset the phone to restore factory settings which rolled back the upgrade.
In software update section, it is saying "Not updated yet" but when I try to upgrade the OS It is saying "You are using the latest software version for current OS." What is causing this issue and how can I upgrade to latest android version?
