When your Xiaomi Redmi Note 3 suddenly stops responding to commands, the screen goes out or a logo followed by a black screen appears, it causes panic. In enthusiastic circles, this is called a βbrickβ, and for owners of this model, this is a familiar problem. The device can hang in an endless reboot (bootloop), show only the icon of the battery with lightning or not show any signs of life when connecting to the charger. Before you carry the phone to the service center, you should try to conduct software resuscitation yourself, since in most cases the problem lies in the firmware failure.
Recovery requires composure and strict follow-up. There are several levels of βbrickingβ: mild when Recovery or Fastboot mode is running, and tough when only Emergency Download (EDL) mode is available. It is critical to determine the current state of the gadget to choose the right treatment. Mistakes in the diagnostic phase can make things worse, so carefully examine the symptoms before starting any software manipulation.
In this article, we will discuss all possible scenarios for the failure of the Redmi Note 3 (both the Prime version on Snapdragon and the usual version on MediaTek). You will learn how to enter special bootloader modes, what drivers are necessary for the computer and how to use the Mi Flash utility correctly. Also pay attention to hardware problems that are often found in this model, for example, a CPU dump or display plume, which can be mistaken by the user as a software failure.
Diagnosis of the condition: determine the type of "brick"
The first step is to determine exactly where the boot stops, and if you press the power button and volume down and you see a hare fixing an android, or you say FASTBOOT on an orange background, you're lucky, it's soft brick, and in that case, the bootloader is intact, and it takes a minimum of time to recover, and you just need to reflash the device in a standard way through the computer.
A more complicated situation arises when the phone responds to the connection to the PC with sound, but the screen remains black. In Windows Device Manager, in this case, the Qualcomm HS-USB QDLoader 9008 port can be determined. This is the EDL mode, which says that the main bootloader is damaged or the firmware is destroyed. To enter this mode on the phone turned off, you usually pin both volume buttons and connect a USB cable. If the computer makes a connection sound, but the screen is silent, this is a good sign for recovery via Mi Flash.
β οΈ Warning: If the phone is warming up in the area of the camera or processor with no apparent load and does not turn on, the problem may be hardware.
There's also a state where the phone shows the Mi logo, then the screen goes out, and the cycle repeats. This is a classic bootloop, and it can be caused by either broken system files or a conflict of installed Magisk modules or custom recovery. For diagnosis, connect your phone to your PC and see if itβs defined as a drive or as a device. ADB. If ADB You can try to clear the data section with the adb shell recovery command. --wipe_data, It's easier to use Fastboot.
Preparation of tools and drivers for firmware
Before you start restoring the Xiaomi Redmi Note 3, you need to prepare the workplace. You will need a computer running Windows (on macOS and Linux tools are unstable or require complex configuration), serviceable. USB-cable, preferably original or high-quality analogue, and stable Internet connection.The software must be installed in advance to avoid timeouts during the critical phase of data recording.
The main tool is the Mi Flash Tool, which should be downloaded only from official sources or trusted forums, such as: 4PDA or XDA Older versions of the program may not support some types of blockers or newer versions of Android, so it is recommended to use the release no older than the previous version. 2018-2019 You'll also need drivers: Qualcomm. HS-USB QDLoader for mode EDL and standard drivers ADB/Fastboot loader-mode.
βοΈ Checklist before firmware
Special attention is paid to the choice of firmware file. For recovery from the "brick" only the version of Fastboot, which has the extension.tgz. Files with the extension.zip are designed to update through Recovery and Fastboot mode via Mi Flash do not work. When downloading, make sure that you take the global version (Global) or Chinese version (China) depending on your preferences, but remember that changing the region (for example, from China to Global) requires an unlocked bootloader.
Recovery through Fastboot mode
If your Redmi Note 3 is in Fastboot mode, the recovery process is the easiest and safest. Run the Mi Flash Tool on your computer and press the Refresh button. If the drivers are installed correctly, the device with its unique code will appear in the list. Press the "Select" button and specify the path to the unpacked firmware folder. Importantly, the path must not contain Cyrillic characters or spaces, otherwise the program will give an error.
At the bottom of the Mi Flash Tool, you'll see three options. To completely delete all data and clean install, choose clean all. If you want to save user data (which is risky when you recover from a crash), you can choose to save user data, but with a brick, you'd better do a full cleanup. The third option, clean all and lock, will lock the bootloader again. Use it only if you're sure of regional firmware compatibility, otherwise the phone will go into a hard brick.
