The situation when your Xiaomi Redmi Note 8 Pro suddenly stops responding to commands, hangs on the logo or goes into an endless reboot is familiar to many users. In the enthusiastic community, this state is called βbrickβ, and it can occur for various reasons, from a failed system update to the accidental deletion of system files.
The process of resuscitation of the smartphone requires care and strict adherence to the instructions, as any wrong actions can aggravate the situation. USB-The key is to identify the type of brick, because the treatments for soft and hard blocking differ dramatically.
In this article, we will go through all the steps of diagnosing and restoring your gadget. We will look at working with Fastboot mode, installing Qualcomm drivers and using specialized software from Xiaomi. Even if the deviceβs screen is completely black, there are ways to make it work again.
Diagnostics of device status and types of locks
The first step before any active action should be to accurately diagnose the current state of the smartphone. Not all freezes are fatal, and sometimes the problem lies in the banal discharge of the battery or a failure of the software interface. Understanding exactly what mode the Redmi Note 8 Pro is in will determine the future strategy of your actions.
There are several main symptoms that can be classified as a problem: If the device vibrates but the screen remains black, or if the display displays the Mi or Redmi logo, followed by a reboot, it is a classic Bootloop, in which case the system cannot boot due to damage to system files or application conflicts.
A more serious situation is considered a complete failure of the device to respond to the on buttons when the phone does not give signs of life even when connecting to the charger. However, even in this case, a low-level boot mode often works, which allows you to restore the firmware.
- π Connect the phone to the charger on 30-40 Check if the charge indicator or vibration will appear.
- π₯οΈ Connect the device to the PC and listen to the sound of the connection USB Check the Device Manager for new ones. COM-port.
- π Press the volume and power buttons at the same time. 15-20 Seconds to force the system to restart.
β οΈ Note: If an unknown device with a yellow exclamation point appears in Device Manager when connecting to a computer, this means that the drivers are not installed or the device is incorrectly defined. Do not try to flash your phone right away until you make sure your computer "sees" the hardware.
It's important to distinguish between a software failure and a physical failure, and if a phone falls into water or is subjected to a severe mechanical impact before it stops turning on, the software techniques may not help, and in such cases, the hardware may be damaged and a diagnosis at a service center will be required.
Tool preparation and driver installation
The success of the Xiaomi Redmi Note 8 Pro recovery operation depends on 90% of the workspace preparation, and you will need a computer running Windows, as most specialized utilities do not have versions for macOS or Linux. Quality is also critically important. USB-cable, preferably original, which is guaranteed to transmit data, not just current.
The most important step in preparing is to install all the drivers you need, and without them, your computer won't be able to communicate properly with your phone in boot modes. ADB/Fastboot And, most importantly, for bricks, Qualcomm drivers. HS-USB QDLoader 9008.
βοΈ Preparations for recovery
Installation of drivers often requires disabling driver signature verification in Windows, especially for older OS versions.This allows the system to accept Qualcomm drivers that do not have a Microsoft digital signature. Once the drivers are installed, it is recommended to restart the computer so that the changes take effect.
You also need to download the current firmware version for your particular model. Pay attention to the region of the device (Global, China, Russia, Europe), as firmware from another region may not stand up or lead to new errors.
Enter Fastboot and EDL mode
Fastboot mode is a low-level interface built into the Android bootloader that allows you to perform various actions with the device, including flashing. To enter this mode on the Redmi Note 8 Pro turned off, you need to press the volume button and, holding it, connect the USB cable to the computer. The logo of the hare in the eardress hat fixing the android should appear on the screen.
If the phone doesnβt respond to the usual button combinations and the screen is black, you may need to enter EDL (Emergency Download Mode) mode, which works at the level of the Qualcomm processor and allows you to restore the device even when the bootloader is completely damaged. Entering the EDL on the Redmi Note 8 Pro often requires disassembling the case and closing test points on the board, or using a special ADB command if the phone is somehow determined by the system.
In Windows Device Manager with a successful entry into mode EDL under βPorts (COM and LPT)" Qualcomm device should appear HS-USB QDLoader 9008. If it is displayed instead"QUSB_BULK", drivers installed incorrectly or manual driver updates are required through Device Manager.
β οΈ Attention: Entering mode EDL Test Point requires you to disassemble your smartphone, and only do this if you are confident in your abilities, because there is a risk of damaging the plumes or static electricity to permanently disable the board.
There's also a software way to log in to EDL via ADB, if the phone is even turned on before the developer menu. The adb reboot edl command sends the device into emergency boot mode. However, for a completely broken phone, this method is not suitable.
What if your computer canβt see your phone in Fastboot?
Recovery with the Mi Flash Tool
The main tool for restoring Xiaomi Redmi Note 8 Pro is the official utility of Mi Flash Tool. This is a program developed by Xiaomi specifically for firmware of its devices in Fastboot and Fastboot modes. EDL. Before starting, make sure that the firmware archive is unpacked into the root folder of the disk, and the path to it does not contain Cyrillic symbols or spaces, for example: C:\mi_flash\ginkgo_global.
After you run the program and connect your phone to Fastboot, click the Refresh button. If the drivers are installed correctly, your device's serial number will appear in the list. Next, you need to choose the firmware method. To completely reset and clean all data, select the clean all option. If you want to save data (which is rarely possible with a brick), choose save user data, but this method may not solve the problem with the bootloader.
Press the Flash button to start the process, at which point new system files will be written to the phone's memory, the progress bar will show the execution status, the whole process can take 200 to 500 seconds, and once completed, the phone will automatically restart.
| Parameter | Description | Recommendation |
|---|---|---|
| clean all | Complete data cleanup and firmware | Recommended for recovery after failures |
| save user data | Data-saving firmware | Use only if the system is loaded |
| clean all + lock | Cleaning, firmware and locking the loader | Only to return to stock with an official BL |
It's important not to interrupt the firmware process or shut down the cable until it's complete. If it's stuck at a certain percentage or has an error, try it. USB-port or reconnect cable. Errors are often associated with unstable connection.
π‘
Only use the 2018 or later version of the Mi Flash Tool for the Redmi Note 8 Pro, as older versions may not work properly with new partitions of this device.
Solving typical firmware errors
During the recovery process, users often encounter various errors, coded by Mi Flash. One of the most common is the error "Miss matching image and device", which means a firmware mismatch of the phone model. This happens if you are trying to flash the global version on a Chinese device or vice versa, or use firmware for another Xiaomi smartphone.
Another common problem is the βAnti-rollback check failedβ error, which is a security mechanism that prevents you from rolling back to an older version of Android if the new version has an increased anti-rollback index.
- π« Flash fail: Often caused by a bad cable or driver. USB 2.0.
- π« Unspported image error: The wrong firmware file is selected or the path to it contains special characters.
- π« "Can't find serial" error: The computer can't see the phone. Check Device Manager and drivers.
If Mi Flash is a bug, but the process is more than 50%, there's a chance the phone will still boot. Try manually pressing the power and volume buttons to exit the firmware mode. If the phone goes into cyclical reboot, the procedure will most likely have to be repeated with another firmware version or cable.
Sometimes it helps to clean the Windows temporary file folder and run the program on behalf of the administrator, and it is also worth checking whether the antivirus does not block the work of the Mi Flash utility, adding it to the exceptions.
Alternative methods and recovery of the loader
If standard methods don't work, you can use console commands through ADB and Fastboot, which requires more technical knowledge, but gives you full control of the device, and you first need to unblock the platform tool folder and open the command line in this directory.
Check communication with the device command fastboot devices. If the serial number is displayed, you can try to clean critical sections manually. For example, the command fastboot erase persist or fastboot erase userdata can help in some cases of getting stuck on the logo. However, use these commands with extreme caution.
β οΈ Attention: The fastboot oem lock command locks the bootloader. If you don't have the original firmware or a modified core, after that command, the phone will stop loading. Use only to return to a fully stocked state.
The Redmi Note 8 Pro also has a problem with the Mi Account lock, and if you drop your phone or reset it with a lock, when you turn it on, it will require you to enter the password from the Mi Account that the device was previously attached to, and it's officially impossible to get around it without a password, it's anti-theft protection.
In the most difficult cases, when software recovery is not possible, only the hardware method with soldering of the memory chip or the use of programmers, such as: UFI Box or EasyJTAG. This requires professional equipment and soldering skills BGA-component.
