When restoring the configuration, several parameters will return "Warning: Argument 0 Read
Only!". This is expected operation.
If for some reason the upgrade process fails, you can log into the radio to see the status using the
"VER" command. If the images you attempted to upgrade (APP, MCU, and DSP) are all filled in and
the currently running image is the one you upgraded, the upgrade succeeded. If an image is not
filled in, you will need to restart the upgrade process at step 1.
If the utility seems to hang when rebooting to the new firmware, you can attempt logging in via a
terminal program to see what state it is in. When you do an upgrade, the Application processor
has to perform an internal upgrade of the DSP and MCU. This takes a few minutes when first
rebooting to the new firmware during which the command line will be non-responsive.
Sometimes the Remote Upgrade Utility never reports that the radio has booted to the new
firmware even though it has, so you can also check this by logging into the radio with your
terminal program. In this case, it is probable that the utility did not get to restore your
configuration, so you should verify the configuration vs. the file retrieved.
There have been cases reported when the instructions are not followed correctly that the radio
does not boot up. In this case, at 115,200 bps when the radio is first powered up you will see
"Booting to Application Image N" and nothing more for over 10 minutes. In this situation, the radio
must be returned to the factory for recovery.
IMPORTANT: You should verify a few important parameters after the upgrade:
