So you have updated your Mi 4i phone onto latest MIUI 22.214.171.124 either using OTA mechanism or flashing it through your computer and then you have lost root access of it. Well, that’s obvious since each time you’ve updated your phone’s operating system (OS) then the installed root exploit would also be removed. It means, you have to do the rooting again. For your information, Xiaomi have pushed an update to most of their devices to MIUI 7.1.1 including to the Mi 4i.
Previously, you might simply root your phone using either Kingroot or Mi4i Toolkit. But with the newly pushed MIUI update you no longer be able to use the same method to gain root access. On the other hand, root access might be necessary for you to run root-only apps. Luckily, you can now make use of the latest SuperSU binary to infiltrate inside your phone’s system and gain full root access.
Before you proceed, I should warn you that rooting may void your phone warranty (even though it’s cool) and basically Xiaomi has provided root access by default on MIUI 7.1.1. So proceed if only you are sure and really, really want to do so (getting full root).
- Make sure your Mi4i is running MIUI 126.96.36.199.
- Make sure your phone has at least 80% battery power remaining
- Create full backup of your data. Just in case something went wrong.
- Install TWRP Custom Recovery on your Mi 4i
- About 30 minutes of your time
Step 1 – Download Update SuperSU v2.65 binary package into your computer.
Step 2 – The file is in .zip format but make sure you don’t extract it which simply that is not necessary. Now connect your phone to computer and transfer that newly downloaded .zip file into your phone’s internal storage. Make sure it is not inside and folder.
Step 3 – Restart your phone into Recovery mode. Doing so is easy: go to Settings > Updater > Menu (the three dots in top right corner). Finally choose Reboot to Recovery Mode.
Step 4 – Now you should have already been in TWRP Recovery screen. Choose / tap on Install then locate the Update-SuperSU .zip file you copied earlier.
Step 5 – TWRP may ask you to Swipe to Flash. Simply do that swiping so the SuperSU file will be flashed.
Step 6 – Sit tight and wait till the flashing process finished. Your phone may reboot and probably it take longer than usual but don’t worry it’s normal.
Voila! Your Xiaomi Mi4i MIUI 188.8.131.52 is now rooted. You can confirm it by installing Root Checker app from Play Store.
You may also find new app namely SuperSU installed and placed on your apps drawer. But if not, you can download it manually from Play Store as well.
How to unroot
Simply launch SuperSU app, go to Settings, find the Full Unroot option then tap on it to proceed. Your phone may reboot.
p.s: If somehow the root process failed, also do try using Update SuperSU v2.46 instead of v2.65.
