In case you’ve got previously installed versions of TWRP, download and extract TWRP_Hydrogen_126.96.36.199_All. Move the folder to your phone storage and flash the image using already installed TWRP recovery. Don’t forget to reboot after flashing and voila, the new TWRP is installed.
Download Global ROM for Recovery and also move it to the phone storage.

Clear all caches after successful flashing.
Don’t reboot now and return to “Flash zip” menu and install Super SU by selecting .zip archive.
Press “Reboot in OS” and wait for system to start.
Now we’ve got Global ROM flashed, with root and TWRP. All data on flash memory is saved, including backup.
