Xiaomi Redmi Note 3 Pro (codenamed Kenzo) remains a budget legend, but the standard MIUI shell can limit the capabilities of advanced users. Obtaining superuser rights and installing custom recavators are impossible without first unlocking the bootloader. This process opens access to deep customization of the system, but requires care and preparation.
The Bootloader unlocking procedure on Xiaomi devices is officially supported by the developer, but it imposes a number of restrictions: you will need a stable Internet connection, a Mi Account that will be associated with the device, and special software. It is important to understand that after successful completion of the operation, all data on the internal drive will be irretrievably deleted.
In this guide, we will discuss each step in detail, from obtaining rights in the account to the final unblocking through the Mi Unlock Tool utility. We will look at typical errors, how to fix them and the nuances of working with drivers in the Windows operating system. Waiting time can be from 72 hours to 360 hours (15 days) from the date of filing, so be patient.

Installation of drivers and preparation of PC
The correct drivers are needed to successfully communicate with your computer in Fastboot mode. Windows 10 and 11 often automatically install the basic drivers, but it is better to use specific versions from Google or Xiaomi to work with Mi Unlock and ADB.
Download and install the SDK Platform Tools platform, which contains adb.exe and fastboot.exe utilities.It is also recommended to install the universal Google USB Driver driver or the specialized Xiaomi USB Driver package. If the device is determined with a yellow exclamation mark in the Device Manager, the drivers will have to be manually updated.
☑️ Verification of PC readiness

Going to Fastboot Mode
Fastboot mode is a low-level interface that allows you to flash memory partitions and control the bootloader. On the Redmi Note 3 Pro, this mode is entered by hardware, making it available even if the operating system is not booting.

If instead of a hare, you see the Mi logo and the phone just turns on, you didn't have time to press the button or it was too late. Try again, making sure the button is pressed until the cable is connected. In some cases, it helps to press the power and volume buttons at the same time, but for Kenzo, the method with a single volume button is standard.

Consequences of unlocking the loader
An unlocked bootloader gives you complete freedom of action, but it has its disadvantages, primarily the loss of warranty (if it was still in effect) and the deterioration of data security. Bank applications can fail due to a violation of system integrity, although this is often bypassed by hiding root rights.
The Widevine function L1, high-resolution content reproduction (HD/4K) in streaming services like Netflix, after unlocking, usually downgraded to the level of L1. This means that the video will be played in standard quality (SD).
💡
Unlocking the bootloader is irreversible without flashing the locking stock firmware, but returning to its original state does not restore the Widevine L1.
On the other hand, you get the option to install any modified firmware, such as LineageOS, Pixel Experience or custom MIUI builds. This allows you to extend the life of the device, getting fresh versions of Android, which are not officially released for the Redmi Note 3 Pro.
