[POCO M3 Pro / Redmi Note 10 / 10T 5G] bg0169:
The best tool for this is Magisk - I'm not fully sure how to describe it but it's a root implementation that integrates in the boot/recovery image instead directly in the Android image.

It's a bit tricky, you just need:

PC/Mac;

Android Tools (adb/fastboot);

Android drivers;

Xiaomi Account (Mi ID);

The official Mi Unlock tool or the 3-rd party one - XiaoMiTools;

Magisk APK

Your OS's boot image aaaand, just in case, your vbmeta image.

The Magisk APK you can get from the Dev's GitHub: topjohnwu/Magisk

If you don't have them, the Android Tools you can get from here: Android Tools

The official unlock tool is here: Mi Unlock (direct link), and the 3-rd party one here: XiaoMiTool Dowload page

I couldn't find link with the drivers, so I uploaded them here in the attached files. (Only for Windows)

Also want to mention: I'm not responsible for carelessly bricked and boot looping devices. I'm not a professional, but I've done it before! This tutorial only applies to any Mi/Redmi/POCO devices with MIUI 12 and higher. That's all. :)

Now to setup everything:

Step 1: Asociate Account w/ device (Mi Unlock)

If you want more detailed-on step-by-step turtorial w/ screenshots you can read the Official Xiaomi Unlock Guide.

1. Go back and sign into a Mi Account if you haven't already

2. Go to the setting > About phone > Spam the MIUI Build number 7 times, until a popup says that you're a developer.

3. Go back and scroll down > Additional Settings > Developer options > enable "OEM Unlocking", "USB Debugging" and "USB Debugging (Security Settings)"

4. Go to Mi Unlock and click "Add Account and device" and follow the instructions.

Once the account is successfully added, you should get a message "Added successfully. Mi account is associated with this device now."

5. You may have to wait sometime before your device gets accepted for unlocking

(Mine took an hour, but some people have reported waiting a week. Sheesh!)

6. After that's done,

MAKE SURE YOU HAVE A SIM CARD INSIDE THE PHONE! It will be important to make sure it's yours.

:/

Step 2: Unlock the bootloader

1. Open the folder with the Android tools and start Command prompt/Terminal instance.

2. Type adb devices to check if your device is connected. On your phone you will receive a popup asking for Debugging permissions. Click OK and check again if it shows on the screen.

If you don't see it but receive a popup, open the "Computer Management" app on your PC and go to Device Manager. You will see a unrecognized device with a name corresponding to the product number. Right-click and select Update driver > Browse my computer for drivers > Browse > select folder w/ drivers from the archive > Next > Android ADB Interface > Next > Finish.

Now you should see it. :)

3. Type in adb reboot bootloader. Your phone will restart to a screen with a Russian Mi bunny tweaking the f**ked up Android robot.

From here, I'll be talking about unlocking it w/ XiaoMiTool v2. For the official tool, look at the guide from the link above.

4. Open the app and select Agree > your device's Region

5. Select the option "I want to mod it"

If the app doesn't see the phone, open the "Computer Management" app on your PC and go to Device Manager. You will see a unrecognized device with a name corresponding to the product number. Right-click and select Update driver > Browse my computer for drivers > Let me pick an installed driver/software > Android Bootloader Interface > Next > Finish.

6. Select Unlock Mi Bootloader and follow the steps to log in and verify device.

Step 2: Check Build and version

Go to the settings, "About phone" and look for the MIUI Version and the region on the build number. If your build number has:

MI-Global ROM

EU-European ROM

CN-Chinese ROM

IN-Indian ROM

Example: xxxEUxx means its European ROM.

Also check if it is MIUI 12, 12.5 or 13.

If the boot/vbmeta image is different, the phone may not boot.

Go to MIUIROM, or any other trustworthy source and find the firmware for RN 11SE

In MIUIROM, I saw there are just China and India ROMs for your Note 11, sooo... check for yourself. :/

If you don't find the correct file, you can download the FW for RN 10 5G, BUT ONLY IF IT'S CODENAME IS CAMMELIAN!

Important: Download the FASTBOOT version, because only this package contains the boot/vbmeta images

.

Step 3: Install the Magisk APK on your phone

1. Download it on your PC/Mac and copy it or download it directly to the phone.

2. Install it using any package installer of choice.

3. On your PC/Mac extract the archive and find the boot (boot.img) and vbmeta image (vbmeta.img).

4. COPY the boot image to your phone (preferably Documents because it's the default location). Do not move it, or else you'll need to download it again if something goes wrong!

5. Open the app on your phone and click the "Install" button on Magisk:

6. After successful installation, under the title will be displayed "Done!" (Just in case)

7. Look to make sure where the new boot image is located on the phone.

8. Copy it to your PC/Mac (just in case rename it to boot.img and delete the old one)

Step 4: Installation

1. On your PC/Mac extract the Android Tools folder and copy to it the new boot.img and the vbmeta.img from before.

2. Start a new Command prompt/Terminal instance and type "adb devices" to check if the device is recognized.

3. If it is, type adb reboot fastboot. On your phone, you should see a screen with a blue FASTBOOTD screen.

4. Type "fastboot devices" to check if it's recognized in fastboot mode. If it isn't, follow the steps from Step 1.5.

6. Now run the following set of commands one by one:

fastboot set_active a
fastboot erase boot
fastboot flash boot boot.img
fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
fastboot flash vbmeta_b vbmeta.img
fastboot set_active a
fastboot reboot recovery

7. After the last command, you should be on the recovery screen. Select Reboot > Reboot System.

8. If everything succeeded, your phone should boot straight to MIUI and show as system-as-root in the Magisk app.

If something went wrong, and the phone doesn't boot, run the same commands again, but replace the modded boot.img with the factory one.

Have fun with your rooted Redmi!
