Cisco ISR4331 Router Firmware Upgrade Failure 21 Feb 2025 Friday

Subject: Cisco ISR4331 Router Firmware Upgrade Failure 21 Feb 2025 Friday

Good day from Singapore,

I have used the following guide to upgrade the firmware of my Cisco ISR 433=
1 router.

Reference Guide: Upgrade Firmware on Cisco Devices (Step-by-Step Guide)
Link: https://appuals.com/upgrade-firmware-cisco-devices/

I was trying to upgrade the firmware from isr4300-universalk9.03.16.10.S.15=
5-3.S10-ext.SPA.bin to isr4300-universalk9.17.12.04a.SPA.bin.

In the course of upgrading the firmware, I have executed the following comm=
and.

boot system flash isr4300-universalk9.17.12.04a.SPA.bin

I have also executed "write memory".

However, after rebooting my Cisco ISR 4331 router, I get the following erro=
rs:

[CODE]
unable to open bootflash:/isr4300-universalk9.03.16.10.S.155-3.S10-ext.SPA.=
bin (14)

........

autoboot: boot failed, restarting...

Resetting .......
[/CODE]

Do I need to break into ROMMON and edit the startup configuration file?

Please advise.

Thank you.
