Antwoord op "How to remove retail mode?"I also had few AT&T note 4 on retail mode but this passcodes was able to disable it and i am using it with t-mobile now. Passcode: 5444 and M729Q16K8546. This codes only work for AT&T. I have a sprint note 4 but can't still disable the retail mode. Anyone with an idea on how to disable it?
