My Meizu M1 Note was shipped with the U firmware, so I wanted to change it to the A firmware because of flyme 4.5 and the keyboard bug, then I noticed that my cellular network doesn’t work. After testing many firmware I found that the cellular network only works with the U firmare. Does anyone have a solution ?
Hello, I had the same problem. My M1 came with U firmwere. When I installed A firmwere, I had to manually enter my career settings, I think only the APN has to be modified. Only in U versions the settings were automaticaly detected corectly, so try to manualy enter your career settings. Hope that helps.
