Menu does not work
In some cases, the application or software does not work.
No response after entering *#0011#
Possible causes:
- That it might not be available if used with Verizon.
- On older devices: an important step of installation might not have been done yet. To manually have it be done, while the phone is off, hold power, volume up, and home. In the recovery menu, simply choose Reboot.
- That *#0011# was entered in another app that's not Samsung's Phone app.
*#0011# disappears after entering it, no other response
Possible causes:
- That its app was deactivated, if it was deactivated with the PC program ADB, which may sometimes be called debloating with ADB, the app can be re-activated with
adb shell pm install-existing --user 0 com.sec.android.RilServiceModeApp
Application opens, but all lines are empty
In order for the application to work, it must communicate with the modem software over the RIL. In the event that the application is unable to communicate, all lines are empty, and Airplane Mode in the status bar may be stuck in a half-activated state. This does not affect the Airplane Mode toggle in the settings. Airplane Mode is also known as Flight Mode.
- If you changed the Debug Level in *#9900# to MID or HIGH, change it to LOW.If this does not solve the issue, and it is already on LOW, do not change it to MID or HIGH. Doing so enables Upload Mode, which, during an applicable error, causes the phone to enter a mode similar to a BSOD (blue screen), instead of attempting to automatically recover from the error without notification. Therefore, if the modem software crashes on startup, you might not be able to access your files.
- Get the phone repaired or replaced.
- For advanced users: The advice given by some when cellular does not work is to restore a backup of the EFS. Do not restore a backup of the EFS unless you know what you're doing. There are battery-related files that are not to be rolled back; the restoration may fail, resulting in a broken EFS; and it is safer to change the modem software version, doing so is also more likely to solve the problem.
