Huawei Mate 20 Lite is a part of the flagship series. The phone is designed for mid-range users with the premium looks of the Mate series. This device was released in 2018 running EMUI 8.1 out of the box. 2018 was the year when Huawei stopped providing bootloader codes and users were stuck in the process of rooting this phone. Because bootloader unlock is mandatory for rooting this phone. Now we have a service to unlock the bootloader see here. But Huawei has disabled the bootloader unlock possibility in EMUI 10 so users are left only with 1 option which is EMUI 9.1 for obtaining root rights.
