      Hello Marko,
      I don’t have a huawei device right now with me, so can
      you tell me if there is a wipe or reset kind of option in the update
      menu??

      • Marko Veselinovic

        Hello, i cant get to the update menu trough the Dial *#*#2846579#*#* when i do that nothing happens. I update it by holding volume buttons when powering on the device.
        I think that is because i never got to install the update_data_full_hw_eu.zip so i cant accses the secret menu..
