>>5936191highly depends on the phone model. often carrier specific. see if cf-autoroot supports it. best one right now. I used it on 4.3 then unrooted, went to 4.4, used it again. worked flawlessly. set all my xposed stuff back up. it doesn't trip knox either if you care about that. unless you use a custom bootloader if you want to run another rom, but stock is stable and nice and root opens so much more up.
