Greetings MIUIers
With Anti-Rollback being the trending topics these days many of you on Android 8.0+ versions might have a question if your device is affected by this or not. But before beginning lets see what this feature actually is.
It's pretty clear by its name Anti- Rollback, which means you cannot go back to a previous version of an OS. Basically, the overall goal is to help keep your smartphone or tablet safe against vulnerabilities that have already been patched. So here I am with some simple steps to check if your device is affected by this new security feature or not.


Prerequisites

  • Mi Phone (Bootloader Locked/ Unlocked)
  • Computer with ADB Drivers installed (LINK)

Steps to Follow

  • Turn off your smartphone and boot into fastboot mode (Vol down + Power).

  • Open Command Prompt/ Power Shell in your ADB folder. On Windows, this can be done by holding Shift and Right-clicking then selecting the  “Open command prompt here/ Open PowerShell here” option.

  • Type this command to check if your device is connected :
    1. fastboot devices
    Copy the Code

  • If you get a confirmation like the above image then type this command to check:
    1. fastboot getvar anti
    Copy the Code

  • On your screen, you will get an output as anti x ( x refers to a number).


If you get a number as 1, 2 and 3 then your device is not yet supported with anti-rollback protection.
If you get a number as 4, 5 and ... then your device has anti-rollback protection enabled.


So this lets you know about the status of ARB on your Device.
