If the system UI crashes or a bootloop occurs in Huawei Y6II LYO-L01 mobile, then factory reset is not possible due to FRP lock. In such a case, the FRP partition is forcefully erased with the help of the DA file so that the mobile can restart without any lock. This is the file that bypasses Google's protection layers and empowers the technician to solve the problem.
Some users want to install custom recovery like TWRP or OrangeFox on their Huawei Y6II LYO-L01 mobile, but the mobile's bootloader is locked. This lock can be temporarily disabled using the DA Auth File and custom images can be flashed. This allows the user to use full rooting, custom ROMs, and advanced mods. Without the DA file, all of these things are almost impossible to achieve.
