BEFORE you erase all your personal data (which would cost you time in restoring them later on), you may want to
move apps to your SD Card, or
uninstall apps that are taking up space
in your phone (not in your SD card) first. You can view the space which the apps are taking up under Settings > storage sense > phone > apps+games > [list is here]. You may bulk-uninstall them from that page, too. If needed, you may also want to
delete media files (Photos, Music, Videos) from your phone (
if they're not saved on your SD card) - just be sure to back them up first to your PC. This should free up enough space to be able to install the new updates - worked with my sister's HTC 8s, which has similar memory specs to the L520. Hope this helps.
