T-Mobile LG G3 White Upgrade to Lollipop Successful (FINALLY!!!!!)

I waited patiently for 4 days for the Lollipop OTA update on my White LG G3 Android 4.4.2 KitKat Software Version D85110r, but I am too impatient and couldn't wait any longer! I tried the LG Support Tool solution but when I plugged in my phone, it kept saying I had the latest version! I did some digging online and saw that other owners of the White G3 were having the same problem. Some threads suggested going to the Upgrade Recovery on the Options menu of the LG Support Tool, but I kept getting a message to check the model and serial number. WTF!!

I finally came across this thread and tried some of the recommended steps to upgrade the phone, while it didn't work initially, I pieced together a solution based on the original steps and subsequent user suggestions. FINALLY!!! I have officially upgraded my White LG G3 to Android 5.0.1 Software Version D85120b!

For those still trying to figure out how to upgrade their White LG G3 Android 4.4.2 Software Version D85110r, here is how I did it:

NOTE: While these steps worked for me, I have no idea whether this will work for anyone else. There are no guarantees here. Continue at your own risk!

If your phone is connected to your computer via USB, unplug the USB connection from your phone.

Open the Lg Mobile Support Tool.

Click on Options, then go to Upgrade Recovery.

Click the bottom circle box for IMEI/ESN/MEIND

Entering my IMEI number did not work for me. A user posted their IMEI number 014088000837418 which worked for them with the LG Mobile Support Tool, so I tried that number. SUCCESS!!

NOTE: I do not know if using another devices IMEI has any negative effects, but it seemed to have worked for me. I saw others comment that the IMEI is only used to determine if the device has an upgrade available. While successful, I am not sure if there will be issues later down the line but I am willing to take that risk!

The LG Mobile Support Tool will prompt you to plug in your phone. Power off your phone. Once powered down, push and hold the Volume Up button, then plug the USB cable into your phone, which should already be connected to your computer. Your phone should enter Download Mode.

NOTE: I saw some posts that indicated the LG Mobile Support Tool had issues if the phone was plugged into a USB 3.0 port, but should work on USB 2.0. I am not sure which USB port version my phone was plugged into. If you have any problems after this step, try plugging the USB cable into another USB port on your computer.

Click Retry on the LG Mobile Support Tool. The LG Mobile Support Tool should start downloading the update and then flash it on your phone. You will see the flash progress on your device screen.

Once flashed, the phone will restart. It took longer than usual to restart, which worried me for a sec, but it finally loaded Android 5.0.1 Lollipop Software Version D85120b. The OS upgraded existing apps to run on the new version, which took a little time. After updating stock LG apps and accepting the LG Terms and Conditions, I was all set!

That's it! I finally upgraded my G3 to Lollipop!

Good luck with your upgrade!!
