It works on most phone with new LG stock recovery. In new v20 Stock recovery LG allow user to adb sideload zip and flash anything to our phone. That script just flash su and root your phone.
PS. You cannot use it with old LG recovery.

I know this is an old question but, will i be able to still receive software updates for my Optimus G after i root it with this method? and does this method unlocks the BootLoader?

No, you need to unroot it first. But most unroot method leave some files that make LG OTA fail. So if you root your phone when you need to upgrade with official LG OTA, you need to flash stock kdz back.

ok thanks i just want to clarify that, maybe ill just wait for now. Hoping LG would bring another upgrade before i decide to finally root my phone. Android L maybe? what do you think? would LG ever care to upgrade our G?

IMO, LG will not update our phone to Android L but we will get it from dev anyways. Kitkat v20b update is stable and battery friendly, it maybe last update from LG for our 2 years old phone.

It's such a shame that they are already considering it as kind of Obsolete. The OG still packs a formidable specs(still better than most of Mid-Tier phones lately), and it's an ex-Flagship of LG to start with. I understand they should ditch the OG for their newer products to sell out but it's pretty unfair for those who have the G. Unfair to the fact that the Xperia Z(which has the same specs with OG) is still supported by SONY and it is now on 4.4.4

Help with Root

Guys i recently purchased Verizon VS985 model made in Korea. I am confused about rooting it.
1st thing is I am from India and its unlocked one... If I root it and flash any rom under Verizon Lg forum,,what would happen...do my phone got locked again?
Which method Should i use to root it and flash recovery and roms?

Rooting and flashing a ROM will not affect the unlock. Assuming the phone is running lollipop, use the first method in this thread...

If the script in the first method doesn't work for you, then use the second method. If using the second method, extract the contents of the New_LG_Root_v0.1_by_dig.zip (the link is at the bottom of the OP), and open a command prompt from within the extracted directory. Then run the posted commands in the OP from there. The easiest method of installing TWRP is w/ the TWRP Manager app...

If I downgrade to Lollipop from Marshmallow can I root?

Hi Guys,
I tried rooting my Marhsmallow LG G4 now and I couldn't get passed the step where you type in "ID" in accordance with this guide: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765.
I read somewhere that it was because I upgraded to MarshMallow.
Now - I want to know - If I downgrade to Lollipop can I follow the above root again and it will work?
Thanks!

Yeah.its possible. I returned lollipop from mm using LG up. Used to inject root and I'm using currently my g4 with root access.my recommend try to inject root. You don't need to open bootloader lock.

how to root or downgrade LG G3 D85130e

Alright so i got me a LG G3 and decided i wanted to root it but realized i was on software verison D85130e so there was no root so i found a thread that said downgrade using KDZ well i follwed the insructions to downgrade to D851020E 00 and when i use LG flash tool 2014 it does bot recognize my phone also it will start doing the upgrade stop at 3% pop a error up and try to restart . Now my question is there a way too root or downgrade D85130e ?
thanks in advance

The only way your going to downgrade from 30E is by using LG UP to flash official TOT file. Then from there you will be on KitKat 4.4.2 Google search for the Official build from this link: http://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667

Yes thank you i actually figured it out

I did the same as you, I cannot root 30e, I downgrade to 30d with lg flash tool 2014 and the kdz. then temp root, then twrp, then root.

I managed to successfully downgrade D85130e to D85130d flashing KDZ with LGUP and I'm still on MM 6.0. I've attached a screenshot of the Software info after flashing kdz.
I haven't yet attempted root, so for the time being I disabled OTA Updates by entering 277634#*# into the dialer. From there select Wifi Test, OTA then Disable.
For those that would like the links to the files I downloaded, I will update with those later tonight.

I used NewKingroot ver. 4.9.6. It got me initially got me temp root, then Full root after flashing TWRP, installing LG-D85130D-Flashable.Boot -AUTOREPACK.zip & SuperSu.

Why? If you flash supersu in twrp then you'd have a rooted 30e!

Based upon what I read on other threads, I had the impression it was not currently possible to root 30e. I saw several posts advising to downgrade to 30d because root was only temp with 30e.
I am now on 30d but I suppose could always return to 30e and root again if I feel the need.
The main reason I rooted is so i could remap my MOGA Gamepad to play touch only games with Tincore Keymapper or BT/USB Joystick Center but now I need to find a compatible ROM and Kernel.

Refer to my thread
http://forum.xda-developers.com/tmo...ck-d851-30e-kdz-flashable-zips-t3478560/page1

Yea when i first tryed it i could not get the flash tool to work with 30e and i realized you can only go back so far so i used lg flash tool 2014 and flashed to 30d and temp rooted with kingroot downloaded flashify and flashed TWRP then went into TWRP flashed the Autorepack theb SU cause going throough ADB shell would not flash TWRP correctly for some reason. But i think it is because i did not flash the AUTOREPACK in twrp only SuperSu and that was messing me up cause i thoigh adb shell was installing the repack but i figured it out .

Friends, i'm trying to downgrade my g3 to 30D and when I try to flash through LG Flash tool 2014, nothing happens. I don't see any update progress in my phone and in the tool, it is stuck at 10%. appreciate your help here.
