BigJapan Well, I do not know, some firmware on the 6 android I have given the performance not worse than others.
The first time when I went into the recovery, he gave me something about the Offical TWRP, after installing something about the modified TWRP and Ruth, not allowing to reboot. Then I put the root and re-installed, all the rules. Introduced these errors in the search, I did not find anything. Previously, and without them, the result was the same. TWRP 3.0.3 from Fedor
