[G3 Q&A, Help & Troubleshooting] :
Dear Denizens of XDA!

I've finally fixed my phone upon giving up hope a few months ago. In short points, here is my story:

Installed Freedom.apk (by-pass in-app purchases)

Updated to the latest firmware without removing apk

Could no longer connect to official Google servers (ie playstore, gmail) BUT internet worked

Went to LG for quote on fix, stated that I need to replace motherboard ($250)

Gave up for months until TODAY.

Disclaimers:

I did not develop any of these programs but merely stumbled upon them. I do hope that this solution works for you but I cannot guarantee anything.

Do these at your OWN risk. I cannot and will not be held liable for any further damages caused by following my steps.

My phone:

LG G3 D855K from Telstra August 2014.

(crappy) 2GB ram, 16GB storage model.

I'll give special thanks to these people; I did NOT receive any consult or speak to them but they have provided the tools in which I used to fix my LG G3 which would no longer connect to the Playstore and other important Google services. Many thanks to:

'How I did it':

1 - Download and install the LG USB drivers from [Link 1]

2 - Download and extract [Link 2]

3 - Download your relevant LG G3 Firmware from [Link 3]! Type in your IMEI code to find the exact software/firmware that you require.

4 - Copy the downloaded .kdz file (should be ~1GB) into the same folder as the [Link 2].

7.5 - Please note that the language settings are not necessary. I've simply set it to English so I could read the messages/notifications.

8 - LG Software will pop-up again and let it do its own thing.

9 - An error message of Server couldn't be connected or something of the like will appear. Do NOT press exit.

10 - Look at your phone and you'll see that the firmware updating logo/downloading.

11 - Once your phone reaches 100%, the program on the computer may freeze and be required to be shut down. (This is okay once it's complete).

12 - Allow your phone to reboot, this may take 5-10 minutes.

13 - You'll get the applications being optimized.

14 - Just before you press start the phone may reboot, that's fine as well.

15 - Enjoy!

Unfortunately, I did not expect this to work for me so I do not have any video footage of me actually attempting this procedure.

If you have any other questions or queries please do leave a comment below. I am not an avid user of XDA but will try and respond when I can do so.

Worked? Thank me? (Sorry if I'm optimistic!)

The only thanks I would like to receive if this works is if you can download the firmware from [Link 3], keep a backup, and re-upload it somewhere to share with other users in need.

If you do decide to re-upload, please do keep the details of the firmware.

I hope that this solution does work for you.

And one final reminder that if you do copy what I did, you proceed to do so at your own risk.

Good luck.
