Please help. I tried kingroot it goes until 97 present and said 1 issue optimize system improvement engine. Ask to purify and then failed. I have a android 6.o Lenovo A2016a40.
Some devices are tougher to root than others. I checked on Root checker, and it said that my samsung tab is very hard to root. And they gave it a rank of 8508 (total 11,943 devices). Higher rank higher toughness. Vivo phones are hardest to root.
In order to install TWRP you need to ensure that your bootloader is unlocked, which mostly new devices dont allow (there are methods to force unlock tho)
