How To Fix Root Permissions After Upgrading To MIUI 1.9.9 ROM

MIUI version 1.9.9 started rolling out for select Android devices couple of days back. Our friends at Android Spin discovered that after flashing MIUI 1.9.9, some phones lose root rights! It was discovered while some users tried to restore their apps from Titanium Backup after a fresh MIUI 1.9.9 installation. This is a really simple tip but will save you from the trouble of re-rooting or flashing your phone altogether.

Here are the step by step instructions to re-enable root access on your Android phone after flashing MIUI MIUI-Root=-Fix1.9.9:

  1. The first step is to unlock your phone and go to Tools folder.
  2. In the tools folder, tap on SuperUser icon.
  3. Once SuperUser launches, tap on Menu and select settings.
  4. In the settings menu, you will see a really small and smart Root Permissions On / Off Toggle.
  5. If it is set to off, tap on it to turn Root Permissions on.
  6. Once done, open Titanium Backup or any other app requiring root and see if that fimiliar SU allow / disallow prompt appears.
  7. In case you are still facing the issue, then reboot your device and again check SuperUser settings to see if Root Permissions are enabled.

And there you go! If everything goes as planned, you will certainly have you rooting rights back. We believe that this method is pretty generic and you can deploy it in any MIUI version facing similar issues.

Here is a video of this workaround if you weren’t able to follow written instructions:

In case the above method didn’t work for you, which is very unlikely, then we believe that you will need to re-flash MIUI 1.9.9 or revert back to older version.

Thanks, AndroidSpin


  1. Worked. That was easy. It’s interesting that the default is “off”, when, given the fact that you just flashed MIUI, you’re clearly a root user….
