We told you the software update was coming. Back then it was the ZV26 since that’s the name on the page. However, if we look at the file name it says ZV6. We don’t know if that’s a typo on LG’s front or if they decided to change the name. Anyhow, it’s the same update we were talking about last week and today we’ve reported on the OTA already here. It is not the Android 5.0 Lollipop that is coming to Korea as we speak. However, it does come with more than just Google security patches including International WiFi calling for Sprint subscribers.

Updating your G3 is not complicated. But, there are different ways you can install software and firmware on your smartphone. You can use the OTA release that’s coming or flash the update manually. The steps are the same as the earlier ZV4 update.


You must have the flash Tool to update manually if you don’t wish to wait for the official OTA notification. Note that all of you should have the over the air waves coming. Some of you will have root access and other reasons that make you prefer having the file manually. It’s always risky accepting OTA’s when you are on root except for the odd occasion. Flashing manually is the safest option.

  • The warranty stays by flashing official firmware and those with root access find the warranty working once more.
  • You must download the up to date USB Drivers from the official LG website or use third-party links. Some of you have the drivers working already do you don’t need to search for them again. If you are connecting to the computer and accessing the pictures from the drive you know the drivers are up to date.
  • You must enable USB Debugging mode by visiting the Developer Options menu from the Settings menu.
  • You must have a computer to follow the steps. Correspondingly, you want to stop the antivirus protection running on the computer. Also stop the security on the Android handset.
  • This guide only works for the Sprint phone carrier network. It has a unique model number that you will find from Menu > Settings > About Device. Each file is released for a specific model number. Flashing the wrong file can harm your device.
  • Use this tutorial only if you are an advanced Android user. Find a family member or friend to aid you if you don’t know what you are doing. It’s always best to start with guidance instead of being alone for the first time.
  • Check the battery charge level is over 55% from the status bar. You can see the status bar by turning on the phone and looking across the top of the screen. The status bar is all white to suit KitKat.
  • The following is one of the last stages of KitKat and not 5.0 Lollipop. If you wish to reserve your efforts for Lollipop you should wait a while longer as it’s coming soon. As I mentioned before, it’s rolling out in Korea today.
  • Before installing the new Android 4.4.4 KitKat you should create backups so you aren’t losing data if you must do a factory reset. No data is expected to be lost during an official update. It’s if something goes wrong. Make copies of the phone contacts, SMS texts and market applications using Helium from the Google Play Store if you don’t have a preferred method already. Others may wish to look into signing up with Google Drive and using their free space for a limited amount of GB’s. You can back up to the internal memory because only the ROM is wiped during factory resets. You don’t need to back up to the external SD card

There is no root access on the Zv6 firmware version yet. That means if you wanted to keep the internal system unlocked you must not follow the guide. Furthermore, the ZV6 file blocks the Stump Root. Those wanting to keep root running the Zv6 must be on the ZV4 firmware version and run the Bump’d TWRP. You can check if you still have the default factory restrictions removed by installing the Root Checker and Unroot Pro.
