After seeing multiple users brick their MAG devices or lose working configurations from unnecessary firmware updates, here is my guide on when updates are actually needed.
Legitimate reasons to update:
1. A specific bug you are experiencing is confirmed fixed in a newer version.
2. Your provider requires a minimum firmware version.
3. A security vulnerability has been announced for your current version.
4. You are experiencing the known URL-not-persisting issue that was fixed in later releases.
When you DO decide to update:
1. Screenshot or note your portal URL and custom settings.
2. Download firmware only from infomir.eu for your specific model.
3. Use USB flash drive method, not over-network update.
4. Have the factory reset process ready in case of issues.
5. Do not interrupt power during the update.
Moderator reminder: if you experience firmware-related issues, document your MAG model, old firmware version, and new firmware version when asking for help. This information is essential for accurate advice.
