It seems that LG is taking far too long to launch the highly anticipated Android 5.0 Lollipop update for the old G2 and there is a risk that the firmware update might not come at all.
So instead of fearing for the worse, LG G2 users should head over to XDA instead as there is already an Android 5.0 Lollipop update made available for them there. The Lollipop can be found in a custom ROM that is developed by Rashed97 and it is made specifically for the G2 D800, D801, D802, LS980 and VS980 variants.
Of course, G2 users should note that the custom ROM is still in its early build so there are going to be some issues with it. The good news is that Rashed97 has already promised to fix the issues with the ROM in the near future.
So, if you are among the many G2 users, you are highly recommended to install the custom ROM on your device. All you have to do is go to XDA and download the custom ROM together with the Google Apps Package. Once done, refer to the following instruction:
1. Make sure a backup is created and the device is already rooted with CWM. We recommend doing so with NANDROID.
2. A minimum of 50% battery life to ensure no disruption when installation is taking place.
3. CM12 ROM ZIP downloaded for the G2.
4. Google Apps Package downloaded.
1. Transfer both the Custom ROM and Google Apps Package to your G2.
2. Boot device into recovery mode and wipe cache, data and system partition.
3. Flash the CM12 ROM.
4. Then, Flash the Google Apps Package.
5. The G2 should reboot and it will run on the Lollipop OS.
