Hey!
I bought a Moto X, it turned out to be the X1053 model. The system version is 161.44.35.ghost_row.nii.en.mx, which is Nextel Mexico. When I try to update to 4.4.4 it keeps telling me that there is no update available (4.4.2). I assume it's because of the system version, or Nextel to be more...
