After I purchased my LG G3 in a little while, LG started rolling out the Andriod Lollipop 5.0 update, tried effortlessly but couldn’t get to update it OTA as it says “You have the latest version installed”.
So I searched around a little, and apparently you can get the update via downloading PC Suite and upgrading through there.
NB: With me it only worked on windows 8 or older (Will not work on windows 8.1 and crashed 2 of my PCs – something to do with the drivers installation), also you cannot update using Macbooks and you will loose USB connectivity to your LG G3 from your Mac after the 5.0 update.
All you have to do is :
1. Read the Note above!
2. Backup your phone contents to your memory card or PC (Not mandetory but highly recommended).
3. Download the LG Mobile Support tool and the LG drivers from the LG website (Link here).
4. Update your phone through the LG Mobile Support Tool.
5. Follow through the update and update playstore and all the other apps that require updates through the Google play store.
