Download the regular version of SuperSU from the Play Market (Register on the Play Market) orsavagemessiahzine.com(no registration on the Play Market) -В® SuperSU (Post Displax # 56909507)
I took version 2.82 from here -В® SuperSU (Post Displax # 61917252)
apk -//savagemessiahzine.com/forum/d…3336/SuperSU_v2.82.apk

1. Through the Pro Key
For 7.1.2 in Multi-MEmu we create an image, here is the gear - we change the number of processors and RAM, on the fourth tab we look at Root Mode and Sync Time - enable. We start. Close the assistant. Adjustment (wheel) on the emulator screen, langwich (globe), plus, Russian, drag the mouse for five lines from the right and rearrange it to the first place. You can add to the physical keyboard in two lines where MEmuIME is Russian.
Security (lock) - Unknown sources - allow.
For ease of installation, we set up shared folders (on the right side of the screen, on the daddy panel, or press three points and look for them there) for ease of installation (using Download is best, best without Russian letters). Reboot.
We post two files
//savagemessiahzine.com/forum/d…3336/SuperSU_v2.82.apk
//savagemessiahzine.com/forum/d…/SuperSU+Pro+v2.82.apk

Find them in Download and run. When you start Google offers protection - we refuse !!!!!
We go to SuperSU - Start, writes that it is busy (and suggests how to solve), an arrow to the left in the right panel below, offers to install something (I refused), go to the settings tab - Default access (I set to provide),
Create a name space divided - I removed the tab (lacquers padcher), then we press the installation to the system (otherwise there will be errors), we are overloaded. SuperSU received.

2. Through LuckyPatcher by ChelpuS
Download LuckyPatcher by ChelpuSВ® LuckyPatcher by ChelpuS (Post chelpa # 10727871)
Depending on the installed (or not installed) xposed, select the desired one from the topic header (After delete, leave or reinstall).
I set off from here -В® LuckyPatcher by ChelpuS (Post Cobra111111 # 62132852). This is optional.
Reboot.
Go LuckyPatcher by ChelpuS and apply a custom patch to SuperSU. We leave.
Go to the settings of the SuperSU application - clear the cache.
Then run SuperSU.
Go to the settings SuperSU and set
Permissions - to provide (you can request, but I do not see the point).
Run at startup.
Distributed space - turn off if there is LuckyPatcher by ChelpuS
SuperSu is able to transfer itself to the system partition — to transfer to the system area,
But you can LuckyPatcher by ChelpuS find SuperSU, click next tools - transfer to the system / app.
Reboot.
After transferring, SuperSU is deleted via LuckyPatcher by ChelpuS (Yes, yes, delete! It is in the system area).
LuckyPatcher by ChelpuS can then be deleted or left (depending on the programs used).

We put two applications in order and you will be SuperSU.
//savagemessiahzine.com/forum/d..._patched_Cobra1111.apk
//savagemessiahzine.com/forum/d…489/Enable_SuperSU.apk
We go in the interior to the left. If it requires an update - we update in the normal way.
Download and install the PRO-key (the last -//savagemessiahzine.com/forum/d...e.supersu.pro_2.66.apk )
Reboot the device. Is done.
We go inside the right, if you want to change the settings inside SuperSU (it’s better that you don’t need IMHO).
Go inside in the left.

SuperSU -//savagemessiahzine.com/forum/…3336/SuperSU_v2.82.apk
SuperSU Pro -//savagemessiahzine.com/forum/…/SuperSU+Pro+v2.82.apk

In the settings - Security - turn on Unknown sources and remove the Device Administrators. Root do not forget to enable.
I copied SuperSU and SuperSU PRO via adb (21503 for zero, 21513 for the first, etc.), the paths on the PC indicate our

adb connect 127.0.0.1:21513
adb push "D: \ Downloads \ start \ SuperSU_v2.82.apk" /system/app/SuperSU/SuperSU.apk
adb push "D: \ Downloads \ start \ SuperSU + Pro + v2.82.apk" /system/app/SuperSUPro/SuperSUPro.apk
adb remount

It is possible through any conductor with Root enabled. Create the program and key in the / system / app folder and put the programs there.
If you use CyanogenMod, then you open it, press the three bars at the top left side, a window opens - wheel, basic settings, Access Mode - either Query Mode or Superuser Mode. It may not be possible to go to the internal memory. Log in through the root folder - either SDCARD or (preferably) storage, sdcard0, Download.
Define "Shared Folder" on the toolbar on the right side, the paths where you will upload files.
Easy further. You find the desired SurerSU file ... you click on the box (a bird appears, it writes the selected file), at the top right there are eight points - add to bookmarks, click a rectangle with a circle, the root folder is system-app, click eight dots - there is a "New folder" , create a folder (read the link), go to a new folder, click eight points - Copy the selected ... and for the second file only the folder is a different name.

Reboot. We go to SuperSU - Start, writes that it is busy (and suggests how to solve), an arrow to the left in the right panel below, offers to install something (I refused), go to the settings tab - Default access (I set to provide)
Create space by name - I removed the tab (lacipadcher), do not install it in the system (this button is not active with this method). Reboot for reliability (optional). SuperSU received.
