To cut the long story short, i will suggest you all to get your pockets ready this friday because there is now a way to root android devices v5.0 and v5.1 with the latest version of kingroot.
Before now, android v5.0 devices could only be rooted with kingroot v4.5 whereas android v5.1 requires you having Clockworkmod or TWRP recoveries in order to install SuperSU. But now, with the new kingroot v4.6.2, android users running android v5.1 lolipop can now easily root their android devices.
