PurpleDrake is a set of scripts that will root your LG G3 device and optionally install TWRP recovery by TeamWin.

It works with just about all variants of the LG G3. You can see the PurpleDrake supported devices in their spreadsheet on Google Docs.

TWRP will allow you to easily apply new ROMs to your device. Which is especially helpful, since it is recommended that after you root you should disable OTAs.

1. 
   

   You will need the USB drivers if you are on Windows:

   
   
   


2. 
   
   

   Download PurpleDrake Scripts (currently R03)

   
   


3. 
   

   Extract the files to a folder you can easily get to.

   
   


4. Open the folder


5. 
   

   Run PurpleDrake

   
   
   
   
   • a. OSX: Doubleclick purpledrake_osx
   
   
   
   • b. Linux: In a terminal.
     
     
     
     1. chmod +x purpledrake_linux.sh
     
     
     2. ./purpledrake_linux.sh
     
     
     
     
   
   
   • c. Windows: Doubleclick purpledrake_windows
   
   
   
   


6. 
   
   

   Follow the instructions from within PurpleDrake.

   
   


7. 
   

   After running PurpleDrake, you will still have to install an app like SuperSU, as PurpleDrake does not include one.

   
   


8. Disable OTA [Source]
   
   
   
   • You will probably want to disable the OTA's. From here on out, if you get an update Over-The-Air, you may lose root, or worse, your unlocked bootloader.
   
   
   • From Dialer: 3845#*851# [Replace 851 with your device model number, 850, 855, 990]
   
   
   • Go to WLAN Test => OTA Setting => OFF
   
   
   
   
   

If you install TWRP, then you must be aware, you may run in to issues if you do not disable OTAs.

Some "patches" that come down from the carrier will still notify you even if OTAs is disabled. DO NOT INSTALL OTAs IF YOU INSTALL TWRP, YOU WILL GET STUCK IN A RECOVERY LOOP.

If you get stuck in a Recovery Loop because of an OTA, do not panic, these things always have a fix.

From the TWRP recovery terminal commands enter the following:

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
PRESS ENTER, THEN TYPE

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
PRESS ENTER

REBOOT
