Firmware updates on MAG devices need to be done carefully. Wrong update = bricked device. Here is the safe process.
 
Before anything, identify your exact MAG model. MAG 254, 256, 322, 524 all have different firmware.
 
On the back sticker of the device or in Settings → Information → About.
 
Download firmware only from the official Infomir website: infomir.eu/eng/products/iptv-stb/.
 
Firmware update methods: via USB stick or through the portal menu if the portal supports it.
 
Never download firmware from unofficial sites — risk of malicious code or wrong firmware version.
 
For USB update: format USB as FAT32, place the firmware file in root directory, follow device instructions.
 
Settings → Information shows your current firmware version. Compare with the latest on Infomir site.
 
If using a portal, the portal admin can push firmware updates remotely — contact your provider.
 
After a firmware update, re-enter your portal URL. The update may clear saved portal settings.
 
I recommend noting down your portal URL and MAC before any update in case you need to re-enter.
 
The MAG startup screen shows current firmware version. Check it immediately after any update.
