I'm using the LG Optimus L90 d41510e and today I got the update for Android Lollipop, I downloaded the update and pressed on install, it went to the android logo with the loading bar. After a few minutes of waiting for the update to install, it booted back up but it didn't update, I'm back on 4.4.2 and it says there is no new update anymore. Any solutions? My phone isn't rooted.
