Owning a Xiaomi Redmi 7 offers a lot of customization opportunities, but standard MIUI limitations often prevent advanced users from fully accessing the file system, and it is the first step to installing alternative firmware like LineageOS or TWRP custom recaps.
In this article, we will discuss in detail how to untie the device from the account, get a special unlock key and successfully conduct the procedure through the official Mi Unlock Tool utility. It is important to realize that unlocking the bootloader will forever change the security status of your gadget, but for enthusiasts this is the only opportunity to unlock the potential of the Snapdragon 632 hardware.
Before you start, make sure your device is fully functional and has original firmware. Any manipulation of the system partition requires a stable connection and a charged battery.

Device preparation and data backup
The first and most critical step is to preserve personal information. The process of unlocking the bootloader on Redmi 7 involves a complete formatting of the internal storage. All photos, contacts, messages and installed applications will be permanently deleted immediately after the unlock command is executed, so creating a full backup is a prerequisite for starting work.
Use built-in tools MIUI Or third-party cloud backup services, and the most reliable way to do this is to copy data to a computer through a computer. USB-cable or use Mi Cloud. Don't rely on Google contacts sync alone, as it doesn't save media files and most apps' settings.
⚠️ Warning: Once the bootloader is unlocked, security features such as Find Device and Pay Through NFC (if supported by a bank, may not work properly or be blocked by banks due to a breach of the integrity of the system.
The battery must be charged at least 60% so that the device does not turn off at a critical time of reprogramming the memory chip. USB-A faulty port or cable may cause a 99% error, requiring the entire procedure to be repeated.
- 📱 Make a full backup of all important data to an external medium or to the cloud.
- 🔋 Charge the Xiaomi Redmi smartphone 7 minimum 60-70% steady-work.

☑️ Checklist before kick-off
Account binding and waiting for activation period
Xiaomi’s security policy requires that the Mi Account be linked to the device for a certain period of time before unlocking, which is usually 168 hours (7 days), but in some cases the system may request a wait of up to 30 days, this is done to protect against theft and unauthorized access to previous owners’ data.
To start, log into your smartphone settings and go to Advanced Settings → For Developers. If the item is hidden, click on the MIUI version 7 times in a row in the About Phone section. Find the Device Status option and click Add Account and Device. The system will request confirmation via SMS, and then start countdown.
It's important to stay in your account and not reset during this period. If you reset your phone before the timer expires, the countdown will start again. In 2026, activation servers are stable, but sometimes require re-authorization. Make sure that the date and time are set automatically, as desynchronization can cause a status check error.
After successful binding, the device status menu will display the words "Unlock permitted" with the remaining time, wait until this time period expires. Only after this period, the Mi Unlock utility will be able to execute the lock reset command.
Installation of drivers and PC configuration
To interact with the smartphone in bootloader mode, special drivers are needed, without which the Windows system will not recognize the device in Fastboot mode. It is recommended to install the full Mi Unlock Tool package, which will automatically tighten the necessary components, or use universal drivers. ADB/Fastboot.
Download the current version of Mi Unlock from the official website. When you run it will require authorization in your Mi Account. Make sure your computer has the antivirus and firewall disabled for the duration of the procedure, as they can block low-level access to USB ports.

If the command line window is empty or gives an error, reinstall the drivers manually through the Device Manager.
| Component | Appointment | Status |
|---|---|---|
| Mi Unlock Tool | Official utility for removing the lock | I'll be sure. |
| ADB Drivers | Basic drivers of debugging over USB | Recommended |
| USB Cable | High-quality cable for data transmission | Critically. |
| Wi-Fi / 4G | Stable Internet for checking the server | I'll be sure. |
Unlocking process with Mi Unlock Tool
When the wait period has expired and the drivers are installed, you can move to direct unlock. Put the Redmi 7 smartphone in Fastboot mode, holding the power and volume buttons at the same time. The image of a hare in a hat-hushanka repairing an android will appear on the screen, or the inscription FASTBOOT.

Installation of custom recavery and Root-right
Once the bootloader is unlocked, Redmi 7 owners often seek to gain superuser rights (Root) to take full control of the system, using custom recavators, most commonly TWRP, which allows you to install modified firmware, make full system backups and clear the cache.
Download the current TWRP image for your model (codename onyx). Connect your phone in Fastboot mode and execute the recovery firmware command. Importantly, after the first TWRP installation, you can't immediately boot into the system, otherwise the stock recap will overwrite the custom one.

Tip: Once you have Root rights, hide the Magisk app in its settings and rename it to bypass checks on banking apps. Some banks may block their apps from running on superuser-enabled devices.
Possible mistakes and ways to solve them
Despite the smoothness of the process, users may encounter difficulties. One of the common problems is the "Couldn't verify device" error or endless waiting. This is often due to network problems or the wrong firmware version. Make sure the phone is running a stable version of MIUI, not a beta or Chinese build without a global certificate.
Another common situation is that you lock your account for 7 or 30 days after you try it, and it's not a mistake, it's a security measure, and if you run the timer, you can't get around it, you'll have to wait, and you'll have to wait until you try again before the deadline.
If the phone has gone to Bootloop after unlocking, try a full Wipe Data reset via the Recovery menu. In extreme cases, you will need to flash the device through the Mi Flash Tool in Clean All mode.
⚠️ Note: Using informal patches to bypass the wait (Bypass) may result in the device being blocked by the device. IMEI Use only the official methods described in the instructions.
💡
The main conclusion: Unlocking the bootloader is an irreversible process in terms of data security and security, but it gives you complete control of the device.
