1 - Download the file above and put in the root of your internal storage.
2 - Go to bootloader mode, choose recovery option. Once in recovery option, you'll see NOTHING. Don't worry, press the power button and click in Volume +. Will appear some options, choose "apply update from Sd Card" (or anything like that).
3- Your phone will reboot and you will get the 6.0 Brazilian Marshmallow
4- BE HAPPY!
PS: If there any modifications to the system folder (Root, xposed, any system app removed) won't work. You have to be on a 'clean' stock version.
