I’m having issues with my T-Mobile App Unlock, what can I do?
Some troubleshooting to do before redoing the process.
Must Update to the latest OS = Android 7.0 or latest (for most devices)
Update the Play store & Device Unlock App [Latest Version].
Some other Troubleshooting for APP Unlock FAILED message:
1) Try doing a hard reset (memory reset) so the cache of device is clear and also try taking out / swapping sim cards if possible.
2) APP unlock “fail”: We found a fix if anyone else complains of the unlock “failing”. It looks like the app remembers the last attempt of the unlock or remembers the last “invalid sim” entered in the phone and will stay in the “failed” response until the app is cleared:
How to do that?
- app manager
- look up “device unlock” in app manager
- clear cache
- also clear data.
- exit out.
Now restart device unlock app and the unlock will complete without errors! as always thanks for the support hope this helps future customers problems/questions.
If this still doesn’t work, we will work on further troubleshooting instructions
