After the Galaxy S4, there are some other AT&T devices that have been getting software updates, one of which is the AT&T LG G3 (D850) which has been updated to software version D85010f. If you were expected to get the Android 5.0 Lollipop update with this OTA, you should be a little disappointed because it is still loaded with Android 4.4.2 KitKat.
Maybe you already know that LG had planned to give a Lollipop update in the fourth quarter of 2014, but most likely it isn’t for AT&T variants, but for the Unbranded version of the LG G3, since this phone must go through the carrier certification procedure which requires a long time.
According AT&T Changelogs, the update brings some improvements such as Google Mobile Services (GMS) update, Google security patch, stability improvements, and more pre-installed apps like Mobile TV and Skyfire toolbar removal. Additionally, there’s a user who said that now his phone has better reception after run the 10f software, there must have been some sort of update to the LG G3 radio.
In addition, there is still good news for Android enthusiast, the root remain intact after the D85010f updates. But based on the experience of several users on xda, the root will be retained if you use Stump root utility by jcase before the 10f update.
However, if you used IOroot or towelroot, then you will lose superuser access after OTA installation is complete.
For those who still want to have a root after updating their LG G3 to 10f firmware, here we provide a quick tutorial for you:
- Restore the AT&T LG G3 to stock firmware with LG Flash Tool, it’s required since the official OTA update won’t work when the phone has custom recovery like TWRP.
- After running fully stock firmware, now root the phone with Stump root and then install SuperSU.
- Take the official D85010f OTA update and apply it, it should install without problem.
- After reboot the SuperSU will remain installed, including the su binaries.
- Open Titanium Backup to verify the root on the D85010f firmware for the AT&T LG G3.
