Updating Cisco ISR4331 from Everest (16.06.04) to Fuji (16.09.04)

[stingus]

Hello.

Having trouble updating Cisco ISR4331 from Everest (16.06.04) to Fuji (16.09.04)

Simply copying the firmware to the router and changing "boot system" image isn't helping.

The image is verified.

Router just won't boot into the new firmware and I don't know why. Same thing is going on when I try to downgrade to 16.05.X, but little steps like 16.06.04 -> 16.06.05 or 16.06.06 -> 16.06.04 are working both ways.

I feel that I might be missing something, am I? Maybe there are some extra steps required to update/downgrade to a different major version?

Here's what I have in boot:

Router#sh run br | i booboot-start-marker
boot system flash:isr4300-universalk9.16.09.04.SPA.bin
boot system flash:isr4300-universalk9.16.06.04.SPA.bin
boot-end-marker

Here's what I get when I do the:

verify isr4300-universalk9.16.09.04.SPA.bin

Hey,

I haven't touched an ISR in a while but since it's running IOS XE I have to ask the question.
Is the router running install mode or bundle mode?

Because the bundle mode is where the bin file is still intact and can use the boot system command, but install mode is different.

If you do a dir in priv exec and you see a bunch of .pkg files and a packages.conf file you're in install mode and you'll need to do the install commands.  Please refer to the support page how to perform the upgrade.

Hi!

The router operates in the Bundle mode.

Selecting different boot flash works if I'm moving between the Minor versions (16.06.04->16.06.06->16.06.05 and backwards).

As far as I understand, Bundle mode is on if I have a "boot flash" stated. If it's not stated - router will be working in the Install mode, right?

Router#sh boot
BOOT variable = flash:isr4300-universalk9.16.09.04.SPA.bin,12;flash:isr4300-universalk9.16.06.04.SPA.bin,12;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

Standby not ready to show bootvar

I have not heard of any problems like this. What is your:

config register setting

ROMMON version

also, I don't think it makes much of a difference, maybe it's just habit after all these years, but i typically define the boot statement as:

boot system flash bootflash:filename

again, not sure if any of this is overly relevant but since I've not heard of a problem like this I'm just suggesting the most basic things.

[Leo Laohoo · Accepted solution]

Please read the Release Notes very carefully.
It is not possible to upgrade from 16.6.X to 16.9.X without upgrading the ROMMON first.
WARNING: Upgrade ROMMON to version 16.12(2r) or else you'll brick the router due to CSCvr18589.

[cmarva]

OUCH!

guess I'll be re-doing rommons this weekend.

Hello!
Thank you for the information!
Special thanks for the warning! But doesn't seem to affect my 4331 model.
