1. Root De La Vega does not work to gain ROOT after the update. Correct
2. Kingo will give you ROOT after the update, but Kingo is baaaad and you don't want to leave it installed. Correct, not Long Term.
3. Kingo can be removed after using it to gain ROOT by downloading Chainfire's SU 1.65 APK and flashing it using Flash Gordon to flash w/ no Recovery required. Incorrect/Mostly.
With Root enabled through Kingo go ahead and install Safestrap current version 3.64. Next, download SuperSU Pro zip and store to your Internal/External card (as you will need to install it at a later point). Go ahead and Install Safestrap, this requires you downloading the app and installing same as any other app. With app Installed make sure that Safestrap says it is Installed Recovery and then exit out. Next go into your App Drawer and find SuperSU and find Settings, VERY CAREFULL WITH THIS STEP> scroll down to Switch superuser app (towards the bottom) and select it. YOU WILL LOSE KINGO'S ROOT. IMPORTANT> DO NOT FREAK OUT, REBOOT AND WHEN THE DEVICE RELOADS> AT THE SAFESTRAP SCREEN HIT "RECOVERY" GO IN AND HIT "INSTALL" FIND THE SUPERSU.ZIP AND BAM!!! PERFECTLY NEW!!! BETTER THEN EVER ROOT! Open SU and Grant SuperUser! Enjoy!
The rest is History!
