ok guys i got permanent root there is one pre qualification you will need to accomplish this you must be on software version LS775ZV3 currently this is the only version that can get temp root from kingroot which is what you will need to start this process. ok so if your one of the lucky ones that have that software version and didnt update go here http://xdaforums.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461 and download the latest version of kingroot which i believe is 4.9.6 install it and run it and get temp root, after you verify that your phone is rooted what we need to do now is replace kingroot with super su without rebooting the phone a softboot is ok the temp root will stick with a softboot your going to have to go to the link and follow the guide there to replace kingroot with super su using terminal emulator http://xdaforums.com/a310/general/how-to-remove-replace-kingroot-kinguser-t3308989 . so after you follow that guide kingroot will be gone and super su is now on your phone. super su will ask you to update the su binary make sure to use the normal option, after you press that button it will start to update but will fail so what your going to have to do next is install (Root) FlashFire to install the su binary update manually which can be found here https://play.google.com/store/apps/details?id=eu.chainfire.flash&hl=en and the su binary zip file can be found here http://xdaforums.com/showthread.php?t=1538053 . i recommend the stable version, download that zip and put it at the root of your internal memory after you do that and install FlashFire on your phone its time to get down to business open FlashFire when it asks for root permission make sure to grant it after that hit the + symbol then press the button that says "flash zip or ota" when it opens it will show the content of your internal memory locate the su binary zip file that you put there earlier and press it to load it up to flash, make sure the only thing checked is the "mount/system read/ write" and hit the check mark to ok it then hit the wipe button and make sure the only two things checked are the "Dalvik cache" and the "Cache partition" hit the check mark to ok it. after that scroll down to the very bottom and hit the flash button after that it will start to flash the updated su binary and then it will reboot and i know it seems scary but the red notification light will stay on until it reboots all the way and there will be red text that pops up and says boot verification fail it scared the hell out of me i thought i bricked my phone again anyway give it a minute or two to boot and once its done and boots into android you have a fully rooted LG Stylo 2 like i said i have the boost variant not sure about the other versions but these steps are pretty universal on any android device also just so i don't get blamed do this at your own risk im not responsible for you messing your phone up but it worked for me perfectly i have restarted my phone normally a hundred times and root is there every time anyways enjoy im not much of a developer so please don't ask me about custom recoveries or custom roms i don't do that but now that we have root maybe a developer might come in and help or something.
