These recoveries can root your device by flashing a zip file or an exploit on your device using the recovery mode. However, they may require you to unlock your bootloader first and they may not work on all devices or firmware versions.



Whichever method you choose, make sure to follow the instructions carefully and do not interrupt the rooting process until it is completed. You should also backup your data before rooting and install a root manager app after rooting to manage the root access and permissions on your device.

However, this method may not be available for all devices or regions and it may take some time for the update to reach your device.
