Factory reset does not wipe APN test settings

Legato Application Framework
1

Hi,

I’ve been using target tools like ‘cm data apn’ and ‘cm sim’ to add some test settings to my WP76xx devices.
After executing ‘Erase user partition’ with DS5.3.1 or ‘swiflash -r’ via command line, my test settings are still there (read via cm data or cm sim info).
How can I make sure my device is completely set back to ‘factory defaults’ ?
How can I clear these settings?

Greetings,
annaertd

not sure if AT!RMARESET=1 will help in your case.
Please have a try.

This returns ERROR.

Is this AT command supported on WP7607?
Is there an alternative in Developer Studio?

I guess you can try to go into microcom without the echo option (-E)

microcom /dev/ttyAT

or another solution can be to use it like this but with it you wont be able to see the response:
echo “AT!RMARESET=1” >> /dev/ttyAT

Also WP7607 does have reset command supported according to the AT command Reference document provided by SierraWireless.

Also I think there is a file in legato (some .json) where apns are stored, and clearing that file would make the chip forget the APNs used

I managed to execute the AT!RMARESET command.

microcom /dev/ttyAT
AT!RMARESET=1

The AT command reference explained me that I first had to enter the module password.
After a reboot, my APN were deleted as expected.
