Owners of popular Xiaomi smartphones often face situations when the device stops responding to commands after a failed software experiment. You can even scrape the device at home if you act consistently and do not panic. Most often the problem lies in an interrupted update or attempt to install custom firmware without proper preparation.
There are several levels of "severity" of a breakdown, from a simple reboot cycle to a complete failure of the screen and buttons. In the first case, standard reset methods are sufficient, in the second case, you will need to use specialized software and go to deep diagnostic mode. It is important to understand that the recovery EDL-The mode is the only way to revive the phone when the bootloader is damaged, but requires authorization.
Before you start to take action, you need to assess the scale of the disaster and choose the right tool. Don't be afraid of complex terms like fastboot or recovery, because the recovery process is set up by the manufacturer and the community of enthusiasts. USB-cable and computer with Windows operating system.
Diagnostics of device status
The first step is always to determine exactly what state your Redmi 5 Plus is in. If the phone vibrates, makes sounds, but the screen remains black, that's a good sign - the processor is alive. In the case of complete silence and no response to charging, most likely the problem lies in the hardware or deep battery discharge.
Try to press the power button and one of the volume keys. Volume Down + Power should put the smartphone in Fastboot mode, as an image of a hare repairing an android will tell you. If you press Volume Up + Power, the device should try to enter the Recovery menu. The lack of response to these combinations often indicates the need to use EDL mode.
- 🐰 Screen with a hare – Fastboot mode, bootloader damaged or blocked.
- ⚙️ Recovery menu - system section intact, it is possible to reset settings.
- 🔌 Black screen when connecting to the PC - mode EDL (Qualcomm HS-USB QDLoader).
- 🔄 Infinite reboot – damage to system files or module conflict.
Accurate diagnosis saves time, because the treatments for each condition are dramatically different, and you shouldn't flash your device through Fastboot if it's loading normally in Recovery, and vice versa.
Preparations for system rehabilitation
90% of the success of the operation depends on the correct preparation of the workplace. You will need a Windows computer (preferably version 7, 8 or 10), installed drivers. ADB Fastboot and original or high-quality analogue USB-The use of damaged cables often leads to a connection break at a critical point in firmware.
For Redmi 5 Plus (codename vince), it is important not to confuse the versions, since the firmware from the global version may not stand on the Chinese version and vice versa. The firmware archive must be unpacked, and the path to the folder must not contain Cyrillic characters or spaces so that the firmware utility correctly counts files.
☑️ Checklist of preparations
It is also recommended to disable all unnecessary USB-It's all from the computer, leaving only the keyboard, the mouse and the smartphone, and it minimizes the risk of port conflicts. Before starting any manipulations, back up important data if you can get into the system or restore menu, as the firmware process is guaranteed to delete all user data.
Using the Fastboot mode
Fastboot mode is a low-level protocol that allows you to interact with your phone’s memory directly, bypassing the operating system. If your Redmi 5 Plus shows a rabbit, then this is the preferred recovery method.
After running the program and connecting the device in Fastboot mode, the computer must determine the device. In the Windows Device Manager, the corresponding entry will appear in the "Android Bootloader Interface" or "Android Bootloader Interface" section. If the “Unknown Device” is displayed instead, you must manually update the drivers by indicating the path to the driver folder. ADB/Fastboot.
⚠️ Warning: When choosing a firmware method in the Mi Flash Tool, be extremely careful. the "Clean all" option will completely clear the data, and the "Clean all and lock" will block the bootloader, which can lead to a re-brick if the firmware does not match the region of the device.
The firmware process takes from 300 before 600 It's strictly forbidden to turn off the cable or interrupt the program at this time, and when the process is complete, the phone will automatically restart. 10-15 second-on.

Use it. USB-port located on the back of the system unit, as they provide more stable power and connection than the ports on the front panel or hubs.
Recovery through EDL mode
If the phone doesn’t respond to buttons and doesn’t enter Fastboot, the last chance is EDL (Emergency Download Mode) mode, which is Qualcomm’s emergency boot mode, which allows you to reflash the device even with a completely damaged bootloader.
To transfer the phone to EDL without inclusion, you need to remove the back cover, turn off the battery plume, close special test points (Test Points) with tweezers and, holding the circuit, connect USB-The device manager should have a Qualcomm device HS-USB QDLoader 9008. Only after the appearance of this device, you can open contacts.
| Parameter | Meaning/Description | Importance |
|---|---|---|
| Mode of work | EDL (9008) | Critically. |
| Required software | Mi Flash Tool | Tall. |
| Type of account | Authorized Mi Account | I'll be sure. |
| Driver. | Qualcomm HS-USB QDLoader | Tall. |
The main challenge of EDL is that you need an authorized Xiaomi account, and the official utility requires you to log in with a service employee's license or a special permit, and without authorization, the firmware process will be interrupted at the verification stage, and there are workarounds, but they require deep technical knowledge and are risky.

Problems with the bootloader and Mi Account
A common reason for not being able to restore is a locked bootloader. If you try to install custom Recovery or firmware from another region on a locked device, it will go into a brick. Unlock the bootloader is only possible through the official Mi Unlock utility, but you need to wait 7 days (168 hours) after you link the account.
If the phone was bought by hand, the previous owner could not untie his Mi Account, in which case, after the firmware and reset, the device will require a password from the account, without which it will be impossible to log in, this is protection against theft, and it is almost impossible to circumvent it by legal means. Checking the status of the account lock and the bootloader is a mandatory step before buying used equipment.
- 🔒 Blocked bootloader will not allow you to install custom software.
- 🔑 Mi Account Lock requires the previous owner to enter the password.
- 🌐 The firmware region should coincide with the loader region (Global/CN).
- ⏳ Unlocking the bootloader takes at least 7 days of waiting.
In some cases, only full soldering of memory or the use of paid service programs such as Octoplus or Chimera helps, but this is already the level of a specialized service center.
💡
Successful recovery of Redmi 5 Plus is possible only if the firmware version matches the bootloader type and the correct drivers on the computer.
Frequent mistakes and their solution
In the process of firmware, users often encounter error codes. For example, the error 0x80004005 in the Mi Flash Tool is often solved by renaming the firmware folder in a short name without spaces (for example, C:\rom) and running the program on behalf of the administrator. Missmatching image and device error indicates that you are trying to flash the firmware from another model.
If the process is stuck at a certain percentage (e.g., 54 percent or 99 percent), don't be in a hurry to turn off the cable. Sometimes the processor just takes a long time to process memory partitions. However, if the timer is longer than 10 minutes, it's likely that the firmware file is corrupted or the USB port is unstable. Try the port or cable.
⚠️ Warning: Never interrupt the process of writing persist or modem partitions. Damage to these partitions can result in loss of IMEI, Wi-Fi and Bluetooth, the restoration of which requires the most complex manipulation of backups NV-memory.
Also worth mentioning is the driver problem: Windows 10 and 11 sometimes automatically update Qualcomm drivers to newer versions that don't work with older firmware utilities, in which case you manually roll the driver through Device Manager to the 2016-2017 version.
Preventing future problems
To avoid wondering how to unburrow your phone in the future, you should follow simple rules of operation: Do not disconnect your device from the network during system updates. If you decide to experiment with custom firmware, always do a full backup through TWRP Recovery before any action.
Use only trusted sources to download firmware files. The official miui.com or authorized mirrors are the safest places to go. Avoid questionable builds for gamers or battery savers, which often contain errors in installation scripts.
Check file system integrity and battery status regularly. An old battery can cause your phone to suddenly shut down when you write system files, which is the most common cause of software bricks. Following these guidelines will prolong your Redmi 5 Plus life and save your nerves.
