Why Downgrade the Firmware?
Before we get into the process, let’s quickly talk about why you might need to downgrade your MikroTik CRS125-24G-1S firmware:
- Compatibility Issues: New firmware may not work with your existing network devices or configurations.

Downgrading isn’t something you’ll do often, but when it’s necessary, knowing how to do it safely is key.
Pre-Downgrade Checklist
Before you proceed, make sure you’ve checked off the following items:
- Backup Your Configurations: Downgrading firmware could reset your device to default settings. Save your current configuration by exporting it via Winbox or WebFig.
- Download the Desired Firmware Version: Visit the official MikroTik website (www.mikrotik.com) and download the specific version you want.
- Ensure Stable Power and Connection: Power interruptions during the downgrade can brick your device, so use a UPS or other backup power source.
- Understand the Risks: Downgrading may void warranties or introduce vulnerabilities. Proceed only if necessary.
