-Now I installed the TWRP recovery into the boot partitions: //TWRP// => //Install// => **twrp-installer-3.3.0-2-tissot.zip**. The installation warns about //Running boot image patcher on slot// A and B, and spit some harmless warnings about the **/vendor** mounting point.

It is necessary to install TWRP before Magisk, otherwise TWRP will unroot the phone during its install.

 Finally I repeated the procedure to **backup** the patched **boot_a** and **boot_b** partitions.
 **NOTICE**: the ADB client required to perform the ''adb pull'' command is active when I boot TWRP using ''fastboot boot twrp-3.3.0-2-tissot.img''. If instead I boot TWRP from the phone, the ADB client is not active.
+Once rebooted the phone into normal system, I installed the root permissions manager: **MagiskManager-v7.5.1.apk**.
