Xiaomi Redmi 5 Plus, also known under the code name Vince, has been pleasing users for several years with its reliability, but time takes its toll. Device owners often face the need to reinstall the operating system when official updates stop coming, and the current version of MIUI begins to work unstable or contains errors. Flashing allows not only to return the phone to its former frolicity, but also to install a more recent version of Android, gaining access to new features and security improvements.
The process of replacing software with Redmi 5 Plus can range from simple installation through the update menu to a complex procedure through Fastboot with a complete memory cleanup. It is important to understand that any manipulation of the system partition carries certain risks, and they must be approached by the prepared. In this article, we will discuss in detail all the steps necessary to successfully install the firmware, and also consider how to restore the device in the event of critical errors.
Before you start taking action, you need to be aware of the difference between the types of firmware available for your model. There is a Recovery version that can be installed with standard means, and a Fastboot version that requires a PC connection and special software. The choice of method depends on the current state of your gadget and the goals you set for yourself.
Preparation for firmware: Tools and files
The success of the operation depends on 90% of the correct preparation of the workplace and the collection of the necessary tools. USB-It is also critical to make sure that the battery is at least 60% charged so that the device does not turn off at the most inopportune moment.
To work with Fastboot mode, you need to download and install the ADB and Fastboot drivers on your computer. Without them, the system will not be able to correctly recognize the phone in bootloader mode. In addition, you will need an archiver, such as 7-Zip or WinRAR, to unpack downloaded firmware images, since they often come in compressed format.
The most important step is to select and download the right firmware file. Vince has many builds, from stock global versions to custom ROMs based on LineageOS or Pixel Experience. You should only download files from trusted sources, such as the official MIUI website, the 4PDA forum or XDA Developers, to avoid the introduction of malicious code.
☑️ Checklist before the start of firmware
Remember to make a full backup of all important data. When you flash it, especially through Fastboot, your internal memory will be completely cleaned. Save your contacts, photos and documents to the cloud or to your computer so you don't lose them forever.
Unlocking the Bootloader bootloader
Xiaomi’s official policy requires unlocking the Bootloader to install global firmware on Chinese versions or custom recavers, a mandatory procedure that cannot be avoided by simple methods. The process of linking a Mi Account to a device can take from 7 to 168 hours of waiting, so you need to start in advance.
To start, activate Developer Mode. Go to Settings → About Phone and quickly press 7 times on MIUI Version until you notice that you have become a developer. Then go to the advanced settings and find the Developer option where you need to enable the Factory Unlock option and link an akkaMi account.
⚠️ Note: Once you have enabled the bootloader unlock and account binding, the system will require you to wait a certain time (usually 168 hours.
After the waiting time, connect your phone to your PC in the off state by pressing the Volume down + Power to log in to Fastboot. Launch the Mi Unlock Tool utility on your computer, log in to the same account and follow the instructions on the screen. Successful unlocking will be confirmed by the corresponding message, and the phone will automatically restart.
What to do if the Mi Unlock Tool is in error?
Install firmware through Recovery (without PC)
The most gentle method of updating or changing the firmware region is using the built-in Recovery mode, which is suitable if you already have a bootloader unlocked or you are updating within the same region (for example, from Global to Global). The firmware file must have the.zip extension and be renamed to update.zip.
Place the update.zip file in the root directory of the smartphone's internal memory. Then go to Settings → About Phone, click on the MIUI version icon and select three dots in the corner. In the menu that appears, select Select the firmware file and specify your archive. After confirmation, the file verification and installation process will begin.
- 📂 Make sure that the firmware file is at the root of the memory, not in the folder.
- 🔋 Do not interrupt the installation process, even if the screen is out – the phone may vibrate.
- 🔄 After completion, the device itself restarts to the new system.
If the standard menu method doesn't work, you can use Recovery mode manually. Turn off your phone and press Volume Up + Power. From the menu that appears, select a language (usually English/Chinese), then go to Wipe Data and clear the data, then select Install Update.zip.

Before installing via Recovery, rename the firmware file to update.zip, otherwise the installation menu may not see it.
Firmware via Fastboot with MiFlash
Fastboot is the most powerful and versatile method of firmware, allowing you to completely reassemble the operating system, fixing file system errors and replacing all system partitions. To do this, you will need to download the official MiFlash Tool utility and the firmware archive with the.tgz extension (do not unpack unless otherwise specified in the instructions, but usually MiFlash requires an unpacked folder).
Unpack the firmware archive in the root of the C disk so that the path is short and does not contain Cyrillic, for example: C:\rom_vince_global. Run MiFlash on behalf of the administrator, press the Refresh button and make sure the device is identified (serial number will be displayed). In the upper right corner, select firmware mode: clean all (complete cleaning) or clean all and lock (clean and lock bootloader).
| Firmware mode | Data retention | BL lockdown | Recommendation |
|---|---|---|---|
| clean all | No (full reset) | No. | To change the region or version of Android |
| save user data | Yes. | No. | Update only within one version |
| clean all and lock | No. | Yes. | Only for return to stock (Global to Global) |
Once you select the mode, press the Flash button. It takes 200 to 600 seconds. At this time, you can absolutely not turn off the cable or pull the device. Once you complete the status, you will see the word success, and the phone will go into a reboot. The first download can last up to 10 minutes.
Installation of custom Recovery TWRP
For advanced users who want full control of the Redmi 5 Plus, a third-party TWRP recavator is required. This allows custom firmware, full system backups, and Root rights to be installed. The process requires an unlocked bootloader and a twrp.img image file for the Vince model.
Connect your phone in Fastboot mode to your computer. Open the command line (CMD) in the adb driver folder and enter the command to check the connection: fastboot devices. If the serial number is displayed, you can go to the recover firmware command: fastboot flash recovery twrp.img.
An important nuance for Xiaomi: after firmware TWRP You can’t just reboot your phone to the system, otherwise stock Recovery will overwrite. TWRP. Immediately after the flash command, you either need to pinch the button combination to log in to Recovery, or execute the command: fastboot boot. twrp.img. It'll load up the temporal. TWRP, Where can you install it permanently or flash it? ZIP-patch-box.
⚠️ Attention: When installed TWRP On devices with data encryption, you may need to format the Data partition. In the Wipe menu, select Format Data and type "yes" to delete all files, but allow you to fully work with internal memory in the data. TWRP.
Possible mistakes and ways to solve them
The Xiaomi Redmi 5 Plus flashback can cause various failures, from a logo hover to a complete failure. One of the common problems is the Anti-Rollback error. It is a security mechanism that prevents you from rolling back on an older version of Android if a new one has already been installed. Trying to sew through the old firmware can lead to a “brick” of the device.
If the phone is stuck on the MI (Bootloop) logo, try entering Recovery mode and doing a Wipe Data/Factory Reset, which often helps if the conflict is caused by residual files from the old system. If the reset doesn't help, the system partition may be damaged and you'll need to flash through the Fastboot with a cleanup.
- 🚫 MiFlash's "Missmatching image and device" error means you're trying to flash firmware from another model.
- ⏳ A 3% or 99% freeze in MiFlash is often solved by a replacement. USB-cable.
- 🔒 The “Locked bootloader” error when trying firmware indicates the need to unlock.
In the worst case scenario, if the phone does not respond to buttons and is not included in the Fastboot, you will need to disassemble the device and close the test points on the board to enter EDL mode (Emergency Download), this will allow you to flash the phone even with a completely non-working bootloader, but you need an authorized Mi Account or a special patch for the firmware utility.
💡
The main reason for most firmware errors is the use of incompatible firmware files or interruption of the data writing process. Always check the model and battery power.
