How to unlock the bootloader on Xiaomi Redmi Note 7 Pro

Modern smartphones, especially popular ones like the Xiaomi Redmi Note 7 Pro, often come with limited access to the system partition, which prevents enthusiasts from fully realizing the potential of the device. Unlocking the bootloader is the first and most important step for those who want to install custom firmware, obtain superuser rights or simply clean the device of preinstalled garbage. This process opens the door to a world of deep customization, allowing you to change the system fonts, animations and even the operating system core.

However, before starting the procedure, you need to be clear about the risks: interference with the bootloader will void the manufacturer’s official warranty and can lead to data loss if you do not back up. In addition, some banking applications may stop working normally, although this limitation is also necessary. In this article, we will discuss in detail each stage of preparation and implementation of unlock to minimize possible errors.

Preparation of the device and account Mi

You need to log in to the About menu, click on the MIUI build number several times to activate the developer mode, and then find the appropriate item in the advanced settings.

In the Developer menu, you should activate the Factory Unblock and link your account, then alert you to the risks and require confirmation via SMS or password, and it is critical not to delete your account from your device or log out until you have completed unlocking, otherwise you will have to start over.

⚠️ Warning: After you have your account tied, you have to wait 168 hours (7 days) before you try to unlock.If you try to unlock the device earlier, the timer will reset and the wait will start again.

Make sure your Redmi Note 7 Pro has a stable version installed. MIUI, It's not a beta if you're not sure what you're doing, but also check your battery level, which is at least 60 percent so that the device doesn't turn off at the most inopportune time.

Required tools and drivers

For a successful procedure, you will need a computer running the Windows operating system, since the official Mi Unlock Tool does not have full versions for macOS or Linux without using emulators. You need to install special ADB and Fastboot drivers on your computer that allow the system to recognize the smartphone in bootloader mode. Without properly installed drivers, the utility will see the device as an unknown gadget or will not see it at all.

Download the latest version of the Mi Unlock Tool program from the official MIUI website. Using third-party versions or modified builds can lead to account lock or malfunction of the smartphone. Unpack the archive in the root folder of the disk so that the path does not contain Cyrillic characters, which sometimes causes errors in older versions of the software.

The unlocking process automatically erases all user data, so having a fresh backup is a must before you start.

Installation of custom TWRP Recovery

Immediately after unlocking the bootloader, it is recommended to install custom recovery, such as TWRP, to have full control of the system. Standard Recovery mode does not allow you to install unsigned firmware or make full partition backups. Redmi Note 7 Pro (codename guava) must download a specific version of TWRP that is compatible with the Snapdragon 675 processor.

Put the phone back into Fastboot mode and connect to the PC. In the command line, while in the platform tool folder, type a command to firmware the recovery image. Make sure the image file has an.img extension and is loaded into the correct directory. After the firmware, you need to immediately switch to Recovery mode, clamping down the power buttons and increasing the volume so that the standard firmware does not overwrite TWRP back to stock.

Addressing common problems

One of the common problems is the error "Couldn't verify update package" or hanging on the Mi logo after unlocking.

Security and Return to Stock Firmware

Many users wonder if you can get it back. Yes, you can lock the bootloader back, but you have to be very careful. If you lock the bootloader with custom firmware installed or modified recovery, the device will go into a hard brick, and you can only restore it through the paid service tool EDL.

To return to the original state, you first need to install the official MIUI stock firmware corresponding to your region. After that, while in Fastboot mode, you can execute a lock command, but the safer approach is to simply use a phone with an unlocked bootloader, unless you are confused by the lack of some security features, such as Google Pay in standard mode (although there are ways to bypass).

Remember that an unlocked bootloader makes the device vulnerable to physical attack if it falls into the wrong hands. An attacker can reset the screen password and access data if it is not properly encrypted. So use complex passwords and biometrics, as well as the Find Device feature.

⚠️ Attention: Locking the boot loader (re-lock) on the modified system will make it impossible to boot the OS. Perform this operation only on a fully stock firmware!
