Used this method on previous Sprint LG Optimus G. Do NOT USE, update failed midway and device was never quite the same!
I would also like to share that in the past few years I have had the LG optimus s as well and one of our two phones had problems after an OTA system update.
To those who don't have the update, why don't you install it yourself? Its much much faster and easy. [STOCK] Sprint LG G3 LS990 ZV8 TOT, OTA and &hellip; | Sprint LG G3 | XDA Forums
I wont be thanking Sprint for not having this update. Im switching to somebody else because my experience with Sprint customer service has been terrible.
