    Just a heads up, there’s a mistake in the guide.
    When you’re flashing the recovery you gotta enter “fastboot flash recovery twrp.img”, the “recovery” part is missing from the guide.

      Buddy there no need to relock bootloader .I assume you followed above guide and able to boot in costume recovery twrp,there you have option to backup,make sure you back up to your external store rather than internal.

    Hi Everyone. I solved the SuperSu installation problem downloading the last apk from internet (2.79) and installing it manually.
    Just google “SuperSu latest version zip file”.
    Now my phone is rooted.
