How to flash Xiaomi Redmi Note 8 Pro without unlocking the bootloader

The process of restoring or updating software on the Xiaomi Redmi Note 8 Pro smartphone is often alarming to users, especially when standard methods are used. OTA-The device owners face the necessary firmware procedure, but not everyone has the desire or the ability to spend time waiting for 168 hours to unlock the bootloader. Fortunately, there is an effective way to install official firmware through Recovery mode that doesn’t require superuser rights or open system restrictions.

In this guide, we will discuss how to return to work with your gadget using only the computer and the original cable. You will learn about the nuances of choosing a firmware region, the features of the transition between versions of MIUI and methods for eliminating critical errors that occur in the process. Data security in this process is not guaranteed, so preparation is a key step that can not be ignored.

Before you start taking action, it is important to understand that firmware without unlocking the bootloader means installing only official versions of the software signed by the manufacturer, which means that you will not be able to downgrade (roll back to an older version) without losing data or using special workarounds that may be unstable, but for upgrading to the current version of MIUI or restoring the system after a failure, this method is the most reliable and safe.

Preparation of the device and choice of firmware

The first and most important step is to find the right firmware file. There are many modifications to the Redmi Note 8 Pro (codenamed ginkgo) and installing an inappropriate file can cause the device to fail. You need to determine the current version of the system and region to select the appropriate archive. You can download files from official resources or trusted third-party storage, focusing on the.zip extension for the Recovery method.

• 📱 Make sure your phone model is a Redmi Note 8 Pro, not a regular version or a Redmi Note. 8T.
• 💾 Download Recovery firmware (type Recovery) ROM) with a.zip extension, not a Fastboot ROM.tgz-extensioned.
• 🔋 Charge your smartphone to at least 60% to avoid a sudden power outage during the critical recording phase.
• 💻 Prepare quality. USB-cable, preferably original, for stable connection to the computer if necessary.

It is important to distinguish between firmware types: Global, EEA (Europe), Russia and China. When you change region (for example, from China to Global) through Recovery, data will be deleted automatically, even if you did not choose the cleaning point. China ROM firmware does not have built-in Google services, they will have to be installed manually after launch. If you are not sure about the region, you should choose the Global version that supports all the necessary languages and frequency bands.

After downloading the archive, do not unpack it. the file should lie in the root directory of the internal memory of the smartphone or on the external memory of the smartphone. SD-The computer is only used at this stage as a storage for downloading a heavy file, which is then transferred to the device.

Instructions for Firmware through Recovery Mode

The Built-in Recovery Menu update is a feature of Android and MIUI, which allows you to replace system files without using complex tools like ADB or Fastboot on a PC, ideal when the phone is turned on but not running smoothly, or when you need to upgrade to a new version of MIUI that didn’t come by air.

To begin the procedure, move the downloaded ZIP-archive to the root of internal memory. Then go to the Settings menu → About the phone and click on the version MIUI. In the window that opens, click three dots in the corner and select Select firmware file. Find your archive and confirm the action. The phone will restart and start the installation process.

If the phone doesn't load properly, you can use Recovery mode, which is called by a combination of buttons. Press the volume button and the power button at the same time. After the logo appears, release power, but keep the volume until the menu appears. Here the navigation is done with the volume buttons, and the choice is the power button. Select the language (if any) and press Wipe Data, and then Install Update (or a similar item depending on the Recovery version).

⚠️ Note: With Wipe Data, all photos, contacts and applications will be permanently deleted. Back up important data in the cloud or on your computer in advance.

Use Fastboot and Mi Flash Tool (without unlocking BL)

There is a common misconception that the Mi Flash Tool requires you to unlock the bootloader. flash_all, However, if your bootloader is locked, you can still use Fastboot mode for certain operations, although full-fledged flashing through the cable in this mode without unlocking it. BL It is often impossible to change the region or version (Global) <-> China).

However, Fastboot mode is useful for diagnostics. To get into it, turn off your phone and press the volume button along with the power button. A hare in a hat-earner repairing an android will appear on the screen. By connecting the device to a PC, you can check its visibility in Windows Device Manager.

If you try to flash a Fastboot firmware (.tgz) onto a locked bootloader, the program will give you an error. BL Unlock is the firmware of the same version and region that is already there, and then not always. So for users without unlocking the main method remains through Recovery (ZIP-archive) described above.

Possible mistakes and ways to solve them

Unforeseen situations can occur when you run a Redmi Note 8 Pro firmware, and one of the most common errors is "Can't verify update." This message means that the firmware file's digital signature is not the same as expected or the file is corrupted when downloaded, so you need to re-upload the archive, preferably from another source, and check its checksum.

Another problem is getting stuck on the Mi logo after installation. If the phone is hanging on the screensaver for more than 10-15 minutes, try to force the reboot by holding the power button for 15-20 seconds. If that doesn't work, you'll have to repeat the firmware procedure, but with the mandatory data cleanup (Wipe All Data), as the conflict of the old settings and the new system causes a reboot cycle.

• 🔌 Connection Error: If your computer can't see your phone in Recovery mode, try another one USB-port.
• 📉 Not enough space: Make sure that the internal drive is at least free 5-6 GB space.
• 🔋 Voltage surge: Do not perform the procedure in the cold or with a discharged battery, this may interrupt the recording.

💡

Use a file manager with access to system folders to check if the antivirus does not block the writing of firmware files to the root directory.

Sometimes users are faced with a situation when the fingerprint or camera stops working after the firmware. This is rare for official firmware, but possible when switching between different versions of Android (for example, from Android 9 to 10). In such cases, only a complete reset (Clean All) through Fastboot helps, which, alas, requires an unlocked bootloader. If BL is closed, you can only hope for a patch or call the service.

Recovery after a failed firmware

If experiments have left the phone a brick (black screen, only charging reaction) but the bootloader hasn't been touched, there's a chance to save the device. EDL (Emergency Download Mode) mode allows you to flash the phone even with a locked bootloader, but this requires an authorized Xiaomi account with engineer rights.

The average user's entrance to EDL-A mode (screen with cable) without a special rule of the account will not help, since the Xiaomi server will reject the request for firmware. So the main recommendation is not to interrupt the process of regular updates. If the phone goes into an endless restart (bootloop), try to log into Recovery and make Wipe Data. This will delete all data, but often brings the device back to life.

⚠️ Attention: Attempts to use third-party tools to remove bootloader lock (Bypass Unlock) on modern versions MIUI Often lead to a complete lock of the motherboard (Hard Brick) with the inability to restore even in the service.

The Redmi Note 8 Pro also has a problem with a network dump after running the Chinese version on the global version without unlocking (if questionable methods were used). In normal mode, this situation is excluded through Recovery, since the system simply will not allow you to install an incompatible image. If the network is lost, check the IMEI settings in the engineering menu (available under the code # #3646633#), but be careful when changing the parameters of the radio module.
