Determine if an update is needed
Within the Web User Interface (WebUI), navigate to Administration - Execute a command, and issue
the modem status command: modemstat ?
Note All WebUI Administrative commands can be issued at the Command Line Interface (CLI) using
SSH, Telnet, or serial.
Within the results, the modem firmware version will be listed next to "Firmware:". If this data shows
20.00.**4 or lower, then the modem needs to be updated.
Refer to the image below as a reference:

Update the Modem Firmware
Prerequisites
The following is required to complete this update:
nTransPort device firmware (SarOS) must be running 6.1.3.8 or later, but it is strongly
recommended that the device is running 7.0.0.6 or later.
n50 MB of free storage required by the cellular modem firmware file. If storage is low, contact
Tech support for guidance on freeing space on your router.
nTo allow the appropriate files to be placed onto the device, the local FTP server must be
enabled on the TransPort for all methods that do not involve using Digi Remote Manager for
the upgrade: LAN or WAN.
nAll upgrade methods will need the applyAPN.py Python file as part of the upgrade.
nRecord the APN of the SIM card. If you do not know the APN, you can obtain it by running
modemstat ? command from a command line interface. The APN value is in the APN is use
field.
To determine how much space is available on our router:
1. Within the WebUI, navigate to Administration - Execute a command.
2. Issue the directory command: dir
The last line shows the number of Flash Free bytes.
Best practices
When upgrading your cellular module, any momentary loss of power or event that causes the router or
modem to reset can result in an unrecoverable router. The following should be considered when
performing the update:
nDo not remove power during the modem firmware update process.
nTerminate any operation that may interfere with the modem firmware update process,
including:
lPython applications that programmatically control the cellular modem, for example to
reset the modem, to do fail-over or to enable/disable the modem based on custom logic.
lSureLink recovery mechanisms (i.e., link_retries, check_reg, rebootfails) or dual SIM
failover features.
lRouter recovery mechanisms, like the cloud watchdog feature (cloud 0 watchdog).

Update the Modem Firmware Where to find the updated modem firmware

7
Where to find the updated modem firmware
Using the Public Support site method
You can find the updated modem firmware by using the Public Support site method of upgrading
firmware, which means you have direct access to ftp1.digi.com.
If your router has access to the Digi public support site (ftp1.digi.com), the update can be done using a
single command.
You can test whether you have access to the Digi Public Support site.
1. Within the WebUI, navigate to Administration - Execute a command.
2. Initiate the ping command: ping ftp1.digi.com
3. If you can resolve and connect to ftp1.digi.com, the ping command will return immediately
and show 100 % success.
Not using the Public Support site method
If you are not using the Public Support site method, the updated modem firmware can be found in the
locations specified below.
You can manually pull the modem firmware, which is then written to your router’s Flash drive, and is
then written from Flash to the modem. After the write is completed, you should delete the binary, as it
is large and does not need to be retained.

Note All upgrade methods will need the applyAPN.py Python file as part of the upgrade.
Updating the modem firmware on your router
There are three methods shown below that can be used to download modem firmware and update
your router:
