For those of you who keep asking for OTA updates, here’s a better way to update, just install this CWM-zippable LG8 OTA with root. It will give you everything that comes with the latest LG8 OTA and root for your Sprint Galaxy S3 SPH-L710.
To install, just flash it in CWM and wipe cache after installing then reboot, you should be on the latest LG8 stock ROM with root.
*Note – PLEASE DO NOT FLASH ON ANY OTHER GALAXY S3s!!!!
