Recover firmware preference
The diag test app lted 15 command enables you to restore the preferred modem firmware image.
Sometimes you need to change the modem firmware images to work with different carriers. While writing new images
to the modem, it is quite possible that something unexpected could happen, causing the modem to stop working. To
prevent such accidents from happening, you must always store the original firmware preference in the system before
making any changes on the modem. Usually the system is able to automatically restore the original firmware
information when the firmware upgrade fails, so you do not need to do anything. However, if you experience something
unexpected such as loss of power, you must use this command to restore the modem to its working order after the
modem comes back.

No original modem image information found, no need to recover!
Modem will now reboot!
Set internal USB configuration
It is possible, though rare, that the USB interface composite and device ID can be changed with certain modem
commands, causing the modem to malfunction. If that happens, you can use the diag test app lted 16
command to reset the USB composite and device ID to what you expect them to be.
FortiWiFi-40F-3G4G # dia test app lted 16
Modem USB configuration succeeded! Please reboot the device now.
Your must reboot the modem after using this command. This command has become obsolete
and is no longer applicable to the internal LTE modem in the latest models of the devices.
Get stored images
The diag test app lted 17 command allows you to get the stored images in the modem.
There are two types of images in the modem: a modem image and a carrier profile. The former is like a FortiOSimage
while latter is similar to a configuration file.
The following output shows all the modem images and carrier profiles stored in the modem.
