Owners of the Redmi 5 Plus smartphone, also known as Vince, often face restrictions imposed by the standard MIUI shell. The desire to obtain superuser rights, install a clean operating system or simply restore access to data after a forgotten password leads to the need to flash the device. The main obstacle in this way is a locked bootloader, which can be officially unlocked only after a certain period of time after the account is attached.
There are several methods to do this, each of which requires some preparation and care. In this article, we will discuss how to circumvent standard restrictions and install new firmware even when official methods are unavailable or time-consuming, and you will learn about the necessary tools, risks and technical nuances of working with eMMC partitions.
The process of changing system software always carries the risk of turning the device into a brick, so it is extremely important to carefully monitor each step. Wrong version of drivers or interruption of data recording can lead to irreversible consequences. We will look at proven algorithms of actions that minimize the likelihood of error and help bring the gadget back to life.
To start working, you will need a computer running the Windows operating system, which is serviceable. USB-You also need to download specialized software, including Mi Unlock Tool, Fastboot drivers and firmware images. Without this toolkit, further manipulation is technically impossible.
Tools and drivers preparation
The first step is to organize the workspace and install the software, and the computer must recognize the device in different modes of operation, which requires specific drivers, and often problems arise during the installation of the ADB and Fastboot drivers, since Windows may not have them in the standard set.
You need to download and install the Minimal ADB and Fastboot package, which contains the basic console utilities for interacting with Android. Also critical is the availability of Qualcomm HS-USB QDLoader 9008 drivers, which you will need if the phone goes into emergency boot mode. Without these components, communication between the PC and the smartphone will be impossible.
☑️ Firmware readiness check
Make sure your computer has disabled driver digital signature verification if you are using older versions of Windows.This will allow the system to accept drivers from unknown publishers, which are often used in tools to bypass locks. Once all components are installed, it is recommended to restart the computer to apply the changes.
⚠️ Note: Using drivers from unverified sources can lead to malware infection of your computer.
Unlocking the loader by official method
The safest way to access system partitions is through official unlocking via Xiaomi servers, which requires linking your Mi Account to your phone’s settings and applying for unlocking via a dedicated app, which can take anywhere from a few days to a week, depending on the region and the company’s current policies.
Once you get permission, you need to put your smartphone into Fastboot mode, holding the volume down and power button at the same time, and in this mode, the device connects to the computer, and through the Mi Unlock Tool utility, you request to unlock. Successful execution of the command will open access to the modification of the boot sector.
What do you do when you say "Couldn't verify device"?
It is important to understand that unlocking the bootloader leads to the complete removal of all user data. Android security automatically resets (Wipe Data) when the bootloader status changes to prevent theft of information. Therefore, backing up contacts, photos and messages is a must before starting the procedure.
| Phase | Action. | The result |
|---|---|---|
| 1 | Account binding | The account is displayed in the status of the device |
| 2 | Waiting. | 168 hours (7 days) pass |
| 3 | Launching Mi Unlock | Log in to your PC account |
| 4 | Unlocking | Bootloader Unlocked |
Alternative methods and EDL mode
If the official method is not available or requires too long of waiting, users often turn to alternative methods that exploit vulnerabilities in the Qualcomm bootloader. One such method is to switch to EDL (Emergency Download Mode) mode, which allows you to reflash the device at a low level, bypassing standard checks.
In this mode, Redmi 5 Plus often requires opening the case and closing certain contacts on the board (Test Point) or using special ADB commands if access to the system is still saved. In EDL mode, the device is defined by the computer as Qualcomm HS-USB QDLoader 9008, which allows you to use specialized software to write firmware.
However, it is worth noting that with the release of new versions of the security of MIUI, many vulnerabilities have been closed. Using old exploits may not work on devices with the updated system. In addition, there are authorized service accounts that allow you to run firmware in EDL mode remotely, but this method is usually paid and requires finding intermediaries.
⚠️ Note: Trying to get through the EDL Using unauthorized accounts can cause the device to be locked by serial number.
Installation of custom TWRP Recovery
After successfully unlocking the bootloader, the next logical step is to install a custom recovery menu, such as the TWRP (Team Win Recovery Project). Standard recovery has limited functionality and does not allow you to install modified firmware or make full system backups.
The installation process is done through the command line. First, you need to download the current image. twrp-3.x.x.x-vince.img, Then, in Fastboot mode, you run a command to fastboot flash recovery. twrp-3.x.x.x-vince.img. After completion of the recording, you must immediately switch to recovery mode so as not to overwrite the custom recapvery stock.
This is done using a combination of power and volume buttons, or the fastboot boot command. twrp-3.x.x.x-vince.img It's on the menu. TWRP It is recommended to back up the current system by selecting the Boot, System and Data partitions. This will create a rollback point in case the new firmware is unstable.An exact copy of stock firmware is the only guarantee of returning to the factory state without losing warranty seals (if they are software).
💡
After the first install of TWRP, be sure to go to the Advanced settings and turn off the “Prevent System Read Only” option, otherwise the firmware may not install correctly.
TWRP supports touch control, which makes navigation much easier, so you can format partitions, patch Root rights, and clear cache. It's important to choose format data, not just Wipe, if you change file system type or go from encrypted partition to unencrypted partition.
The process of installing firmware and patches
Direct installation of the new operating system occurs through the Recovery menu.A pre-downloaded archive with firmware (usually in the format.zip) is placed in the internal memory of the phone or on the phone. USB-The storage device. TWRP Select the Install item, then the path to the firmware file is indicated.
Before installing, you need to clean the Data, Cache, and Dalvik partitions completely, and this is done through the Wipe → Advanced Wipe menu. Ignoring this step can lead to a cyclic reboot or application error, especially when switching between different versions of Android or changing the regional version of the firmware.
Once you select the firmware file and swipe to confirm, the writing process will begin, at which time the log of operations will be displayed on the screen. Do not interrupt the process or turn off the device until the message "Successful" appears. After that, you can press the Reboot System button for the first run.
- 🔹 Select the firmware file in the Install menu.
- 🔹 Run the Wipe. Data/Factory Reset.
- 🔹 Run the swipe installation to the right.
- 🔹 Wait for completion and restart the device.
If you plan to get a Root, you can flash the Magisk archive after installing the firmware, but before you boot it up for the first time, which allows you to modify your system files and access secure Android features. However, remember that having Root rights can block some of your banking applications and Google Pay services.
Recovery and problem-solving
Even if all instructions are followed, errors can occur, and the most common problem is that the device goes into an endless restart or hangs on the Mi logo. In such cases, you need to use kembali in Recovery mode and perform a re-cleaning of the data (Format Data), often the problem lies in the conflict of the residual files of the old system.
If the phone stopped responding to buttons and the screen didn't turn on, the boot partition might be damaged, in which case only the firmware through Fastboot in fastboot flash all mode will help. This command completely overwrites all memory partitions, returning the device to the factory state, but with the bootloader unlocked.
💡
Fastboot (Clean All) is a radical but most effective method of solving software errors after unsuccessful experiments.
In cases where even Fastboot does not help, EDL mode remains. Redmi 5 Plus is characterized by a problem with the dumping of the Wi-Fi module after incorrect firmware, since the calibration data is stored in a separate partition. Saving the Persist partition backup before any manipulations can save from loss of functionality of wireless modules.
⚠️ Note: The Persist section contains unique calibration data for sensors and communication modules. its loss or damage can cause Wi-Fi, Bluetooth and accelerometer to fail.
