Updating firmware is important — but before you even think about doing it,
you need to know what version you’re currently running.
Here’s how to check the firmware version on different types of devices — step by step.
✅ 1. On Windows PC (BIOS/UEFI)
-
Press
Windows + R -
Type
msinfo32and press Enter -
Look for BIOS Version/Date in the System Information window
✅ Tip: This shows your motherboard firmware (BIOS/UEFI). For SSDs or devices, check manufacturer tools (e.g., Samsung Magician, Intel Toolbox)
✅ 2. On macOS
-
Click the Apple menu → About This Mac
-
Click System Report
-
Under Hardware, check the Boot ROM Version or SMC Version
These reflect your Mac’s internal firmware version.
✅ 3. On Android devices
-
Go to Settings → About phone
-
Tap Software information or Hardware info
-
Look for Baseband version, Build number, or Firmware version
These vary by device, but all represent firmware identifiers.
✅ 4. On iPhone (iOS)
-
Go to Settings → General → About
-
Scroll to see Modem Firmware
-
This is the cellular radio firmware, often updated with iOS updates
✅ 5. On routers and smart devices
-
Log into your router via browser (e.g.,
192.168.1.1) -
Go to Firmware, Advanced, or System Info tab
-
The current firmware version is usually shown on the home page
For IoT or smart home devices, check the app (like SmartThings, Home Assistant) for firmware status.

You should always check your firmware version before updating
