I have an ISR 4431 router that is stuck in Controller Mode, running IOS XE 16.12.03 Gibraltar.
The command
controller-mode disable
does not exist in this IOS XE version.
Also, having the file
ciscortr.cfg
in
bootflash:/
and it doesn't seem to make a difference.
The only documentation I found refers to IOS XE 17.2 and later: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/install-upgrade-17-2-later.html#switch-modes-using-cisco-cli
How do I change the ISR 4431 back to Autonomous Mode on 16.12.03?
Thank you!
Jason

I was able to recover the unit using a 2nd ISR 4431 that had IOS XE 16.06.04. I copied the older IOS image to
bootflash:/
and the
startup-config
from the working 2nd router to
nvram:/.
Then I reloaded the bad router and interrupted the boot process to enter rommon and executed the following command:
boot bootflash:/<ISR_4400_16.06.04_image>.
When the system booted, I confirmed it was now operating in autonomous mode.

If the router is in ROMMON, post the complete output to the command
set
If the router boots into IOS, post the complete output to the command
dir

I still want to see the complete output to the command
set
to make sure the settings is permanent.

I have confirmed that the settings are permanent.
Here is the output from the set command:
romon 1 > set
PS1=rommon 1 >
THRPUT=
MCP_STARTUP_TRACEFLAGS=00000000:00000000
BOOT=bootflash:/isr4400-universalk9.16.06.04.SPA.bin,1;
LICENSE_BOOT_LEVEL=
BSI=0
RANDOM_NUM=19058…
RED_2_RTS=20:32:50…
RED_2_RCALTS=16710…

In ROMMON, do the following:
DEVICE_MANAGED_MODE autonomous
or
DEVICE_MANAGED_MODE = autonomous
And then reboot.

Both
DEVICE_MANAGED_MODE autonomous
and
DEVICE_MANAGED_MODE = autonomous
have the error message monitor: command "DEVICE_MANAGED_MODE" not found.
However, "DEVICE_MANAGED_MODE=autonomous" is accepted and I can see new entry in the output of the "set" command. When I reboot the router and go in to ROMMON, I notice that the "DEVICE_MANAGED_MODE=autonomous" setting is not persistent.

Post the complete output to the command "dir flash:".
