    1. Instructions says.. if you see your device serial number printed in command windows then your device is ready to be flashed.
      But the main problem is volte.img file is not opening it says.. error: cannot load 'volte.img'

      Now wht to do ?? :(

      Delete
    2. That is a common problem with CMD and ADB..
      while giving path for VoLTE image make sure that there must be no GAB in between the lines
      like
      "fastboot flash modem "c://users/haxx/desktop/new folder/VoLTE.img"
      it should be like
      "c://users/haxx/desktop/new_folder/VoLTE.img"
      no gap..

    1. hy Ezaj!
      I am sorry i was unable to reply you, Because my Semesters are on going..
      The problem you are facing is because you didn't have Asus Mobile Drivers.. I will update the blog with the drivers tomorrow.. Then you have to install them. Then you will be able to see your device in CMD..
      Installing drivers will be a little tricky so try it, if you not able to do so them comment back here and i will connect you with team viewer and i will show you how to do so..
      Thanks..
