Now accepting donations to get my own LG G3 ​
How-to:
Easy as 1-2-3!
1 Run ioroot.bat, ioroot.sh, ioroot.tool or open command prompt/terminal, cd into /ioroot/bts/ and type;
Code:
adb reboot recovery
If you DO NOT have this menu in stock recovery IOroot will not work for you!
2 Select "Apply update from ADB" w/power button. Sideload mode is now enabled.
3 Continue with the script or manually sideload;
Code:
adb sideload datroot.zip
DAT ROOT means JAILBREAK!
Extended info and FAQ below...
Download and extract the latest ioroot.zip... datroot.zip is inside /ioroot/bts/
ioroot also jailbreaks other LG devices. Supported devices are found in the device list in this thread.
Enable "USB Debugging" on phone. Accept RSA certificate to allow ADB access. Not accepting RSA will cause ADB device to show as "offline"
Verizon users must also enable "Ethernet" for USB mode.
Windows:
Install drivers.
Double-click on ioroot.bat
Linux:
Open terminal and cd into ioroot folder
chmod +x ioroot.sh
./ioroot.sh
Mac:
Double-click the ioroot.tool file to launch script.
May need to chmod +x ioroot.tool file first.
FAQ
Q: Will this jailbreak other LG devices?
A: It will jailbreak any LG device which can be booted into stock recovery with menu. Confirmed devices are found in the device list in this thread.
Q: Why do I see an android with a red x or just reboot when I try to get into recovery?
A: Your device has a lame recovery and may have issues jailbreaking w/current IOroot 4.4.2. Use a cooler device or send me a LG G3 so I can work on a real phone.
Q: Will this root non-LG devices?
A: Probably not.
Q: The script doesn't work for me, can you help?
A: No, use terminal to manually enter the commands or ask for help in the thread.
Q: I can't get 'adb devices' to see me phone, can you help?
A: learn2android
Q: Know any hip places to hang out and talk with other nice people about the LG G3?
A: Check us out on IRC: #lg-g3 on Freenode
Q: Which LG G3 do you have?
A: I don't have one yet... you should send me one.

IOroot was originally a Windows script to root the LG G2 on 4.2.2 [URL="http://forum.xda-developers.com/showthread.php?t=2448887"]made by IOMonster[/URL].
It was based on the original adb backdoor found by GiantPune and later [URL="http://forum.xda-developers.com/showthread.php?t=2169117"]posted by jcase[/URL].
The script has grown to support various other LG devices on Android 4.0 - 4.4.2...
Supported devices include LG Optimus G, G2, G3, G Pro, G Pro 2, G Flex and G Pad just to name a few.

4.4.2 method should work for any G3 that can be booted into stock recovery. "adb reboot recovery" should take you to a stock recovery screen with a menu. If you get an Android figure with an error this 4.4.2 root will not work for you.
Anyone with a G3 that is not a F400 please test IOroot25r1 on your phone and report if you can get into the stock recovery menu and if you can root your phone!
LS990 is Sprint's G3, VS985 is Verizon's G3, D850 is AT&T's G3, D851 is T-Mobile's G3, D852 is Canada's G3, and D855 is International.

Open iTunes >
Hold the option key while clicking the "Check for updates" button >
Locate stock .tot file and select it >
iTunes will pop up saying the device will be updated to 4.4.2; hit ok.
If that doesn't work... RMA.

both ioroot and towelroot works on LG G3 100%. towelroot is awesome and works on just about all LG phones period.
ioroots only "advantage" is that if LG patches towelroot in future builds(which won't happen for awhile)... ioroot may still work on new builds.
ioroot also has the option to temproot(not void warranty) 4.2.2 builds with the LG Optimus G, G Pro, G Pro 2, G2 and G Flex. Obviously irrelevant in a G3 thread though.

Will it work on the Verizon GPad with 4.4.2? Some say they have the update, some say they don't.

I dunno why, but I can't backup my EFS.
After typing su, all the commands I type repeat itself and doing nothing. Any idea of why?
Edit : Never mind XD it was a adb server problem. Tried it again and it works perfectly Thank you for the root tool!
