So ive been struck by the camera and wallet glitch regarding the gps update, and i discovered that i bought a xiaomi 13 that already has xiaomi.eu rom which is non official i think, and ive seen that the only way for me to solve without root is to update it to the weekly/bet version so id like to pls ask how do i do it, pls note that i dont know nothing about custom roms, so please explain in simple terms, cause my phone is completely useless rn.
