How to properly upgrade Xiaomi Redmi phone: 4 proven ways + error solving

The Xiaomi Redmi firmware update is a procedure that can both improve the device’s performance and lead to serious problems if something is done wrong. With each new MIUI release, the manufacturer fixes bugs, adds features and optimizes power consumption, but not all users know how to upgrade safely. In this article, we will analyze all current upgrade methods (including hidden ones), tell you how to avoid errors like ERROR 7 or Couldn’t verify update, and give a checklist to prepare the phone.

Redmi’s feature is that even budget models (like Redmi Note 12 or Redmi 10C) support multiple update channels: stable, beta, and custom firmware. The choice of method depends on your model, current version of MIUI, and even the region (Chinese, global or European builds are updated in different ways), and we have compiled instructions that are suitable for both beginners and experienced users who want to reflash the phone via Fastboot or EDL.

1.Preparing the phone for an update: 5 mandatory steps

Before you update Redmi, you need to do a few critical things to keep you from losing data or “bricking” your device, and even if you upgrade through the standard menu, ignoring these steps can cause you to crash.

First and most important, check the battery. The upgrade process can take anywhere from 10 to 40 minutes (depending on the method), and if the phone turns off in the middle, the consequences will be dire. The optimal charge level is at least 60%, but you better connect the device to charge for the duration of the procedure. Also make sure you have backups of important data: contacts, photos and applications. An update via Recovery or Fastboot can erase user files.

• 🔋 Battery charge: at least 60%, ideally 80%+
• 📱 Free space: at least 3 GB on internal storage
• 🔗 A stable Internet connection (for the OTA-update)
• 📝 Backup data (via Mi Cloud or locally)
• 🔧 Disable root access and unlock the bootloader (if any)

If you are upgrading from custom firmware (like LineageOS or Pixel Experience), return to the official MIUI via Fastboot. Otherwise, there is a high risk of an Anti-rollback error that will lock the phone. To check the current firmware version, go to Settings → About Phone → MIUI Version. Write down or take a picture of this information – it will be needed to select the correct update file.

⚠️ Note: If your Redmi was purchased in China (suffix version) CN In the model, do not try to flash it with global firmware without unlocking the bootloader. IMEI loss of network.

Make a backup using Mi Cloud or Google Drive

Check the vacant space (minimum 3 GB)

Disable VPN and proxy (can block Xiaomi servers)

Make sure the phone is not rooted

2. Method 1: Air Update (OTA) is the easiest method

Most Redmi users update their phones through OTA (Over-The-Air), which does not require a computer and is suitable for installing both stable and beta versions of MIUI. The main advantage is to save all data and settings. However, there are limitations: OTA is only available for official firmware, and the upgrade weight usually does not exceed 1.5-2 GB (full firmware weighs 3-4 GB).

To check for updates:

1. Open the Settings. → The phone.
2. Slip on the item System Update (or MIUI version in English firmware).
3. Click Check for updates.
4. If you find an update, click Download (Wi-Fi required).
5. After downloading, select Install Now or Install Later.

If the update isn’t there, but you know it’s out for your model, try the following:

• 🔄 Restart your phone and check again.
• 🌐 Connect to another Wi-Fi network (sometimes the provider blocks Xiaomi servers).
• 📅 Check if the beta has expired (if you are in the tester program).
• 📦 Manually download. OTA-package from the Xiaomi Firmware website and install it through Settings → Updating the system → Three points. → Select the update file.

⚠️ Attention: If after OTA-The phone has been stuck on the Redmi logo for more than 10 minutes, don't panic. Give it another 15 to 20 minutes -- sometimes the first boot after the upgrade takes a long time. If the screen stays black, try pressing the power button for 20 seconds to force a reboot.

3. Method 2: Update via Recovery - if OTA doesn't work

If your Redmi doesn’t see an update through OTA or if it’s an error when you install it, you can use Recovery Mode, which is suitable for installing full firmware (weighing 2-3 GB) and often helps in cases where the phone is stuck on the old version.

Instructions for updating through Recovery:

1. Download the official firmware for your model from Xiaomi Firmware. Look for a file with the.zip extension and the Recovery tag.
2. Rename the file to update.zip (required!) and move it to the root of the phone’s internal memory (not folders!).
3. Turn off the phone.
4. Press the Volume Up + Power combination and hold for 5-10 seconds until the Mi logo and Recovery menu appear.
5. Select the language (if you have a choice) from the menu, then tap on Install update.zip (or similar).
6. Confirm the installation and wait until the process is completed (don’t interrupt!).
7. After successful installation, select Reboot → Reboot to System.

If the phone is unable to verify the update after the reboot, you probably didn’t download the firmware for your model or region. Check the version in the file name (e.g., ingres is global, xmcn is Chinese).

4. Method 3: Fastboot Firmware for Power Users

Updating via Fastboot is a more difficult but also more reliable method, especially if your Redmi is not booting or has a damaged firmware.This method requires a computer with Xiaomi drivers installed and the Mi Flash Tool utility. The main advantage is the ability to flash the phone even in a “brick” state (if the bootloader is not damaged).

Before starting, make sure that:

• 🖥️ Xiaomi drivers are installed on the computer (you can download via Mi). PC Suite).
• 🔌 You have the original. USB-cable (cheap cables may not transmit data to Fastboot).
• 📁 Downloaded the correct firmware for your model (file with the extension.tgz or.zip for Fastboot).
• 🔓 Unlocked bootloader (if you are streaming the unofficial version).

Step-by-step:

1. Unpack the downloaded firmware in a folder on your computer (for example, C:\MiFlash\rom).
2. Turn off your phone and press Volume Down + Power to enter the Fastboot (a rabbit in a hat will appear on the screen).
3. Connect your phone to your computer via USB.
4. Start the Mi Flash Tool (you can download from the official website).
5. In the program, click Select and specify the path to the folder with the firmware.
6. Press Refresh – your Redmi should appear in the list of devices.
7. Select firmware mode: Clean all - complete clean (removes all data); Save user data - saving user files (not always stable); Clean all and lock - cleaning + locking the bootloader (only for official firmware).

Flash

After successful firmware, the phone will restart automatically.

⚠️ Note: If the Mi Flash Tool gives an error critical partition flashing is not allowed, it means that you are trying to flash the phone with the bootloader locked with an unofficial firmware. Unlock the bootloader through the Mi Unlock Tool or use the official firmware.

1. Reinstall the driver manually through Device Manager (select "ADB Interface").

2. Use another USB-port (preferably) USB 2.0).

3. run the program on behalf of the administrator.

4. disable the antivirus (it can block access to the firmware).-->

5. Method 4: Firmware via EDL (Emergency Mode) - if the phone does not turn on

EDL (Emergency Download Mode) is the last chance to bring Redmi back to life if it doesn't respond to buttons, doesn't load, or issues a Qualcomm HS-USB QDLoader 9008 error. In this mode, firmware is low, bypassing the Android bootloader. However, EDL requires a special cable or testpoint (on some models), as well as knowing the exact model name.

Warning: Firmware via EDL erases all data without recovery and can result in a loss of IMEI if something goes wrong, a method recommended only in extreme cases where other methods have failed.

Instructions for firmware through EDL:

1. Download firmware for EDL (usually a file marked EDL or firehose) and the Mi Flash Tool (2018 or later).
2. Turn off the phone. If it doesn't respond, remove and insert the battery back (if it's removable).
3. Connect the phone to your computer by holding the buttons Volume up + Volume down (on some models you need to close the testpoint).
4. The Qualcomm HS-USB QDLoader 9008 should appear in Device Manager. If it is not available, install the driver manually.
5. Launch the Mi Flash Tool, select the firmware folder and press Flash.
6. Wait until the process is completed (it can take up to 30 minutes).
7. After successful firmware, the phone will restart in normal mode.

If the phone fails to turn on or gives an Invalid IMEI error after running through EDL, you will need to restore the IMEI using an engineering menu or programs like Maui META (for MediaTek processors) or QCN Rebuilder (for Qualcomm).

💡

Firmware through EDL is a last resort, and if you're not sure what you're doing, you'd better take your phone to the service, and if you don't have the right firmware in this mode, it can permanently shut down your device.

6.Typical errors when updating Redmi and how to fix them

Even when following the instructions, Xiaomi Redmi users often encounter errors, and let’s look at the most common ones and how to fix them.

If your Redmi has stopped turning on or boots into an endless bootloom (cyclical reboot) after a failed update, try the following:

• 🔄 Reset with Recovery: Select Wipe Data → Wipe All Data.
• 📥 Swipe your phone through Fastboot with a full clean (Clean all).
• 🔧 If nothing helps, use it. EDL-the regime (see previous section).

If the update has lost sound, the camera is not working or the mobile network is missing, most likely the firmware was installed incorrectly or not for your region.

1. Check the firmware version in Settings → About the phone.
2. Download the full firmware for your model and region from the official website.
3. Swipe your phone through Fastboot with a full clean.

7. How to roll back to the previous version of MIUI

Sometimes a new update brings more problems than benefits: bugs, brakes or app incompatibility. In this case, you can return the previous version of MIUI, but there are a few nuances. First, Xiaomi blocks the rollback of older versions through the Anti-Rollback mechanism. Second, a rollback can lead to data loss if you do not backup.

To safely roll back:

1. Download the full firmware of the desired version from the official website (make sure that it is older than the current one).
2. Unpack the file and find the Fastboot firmware folder inside.
3. Connect your phone in Fastboot mode and run through the Mi Flash Tool with a full clean (Clean all).
4. If an Anti-rollback error appears, a rollback is not possible – you will have to stay on the current version or wait for a new update.

On some Redmi models (such as the Redmi Note 10 Pro or Redmi K40), rollbacks are only possible within one MIUI branch. For example, if you have a MIUI 14 installed, you can only roll back on MIUI 13, but not on MIUI 12. Before rolling back, check the compatibility of versions on forums like Xiaomi.eu or XDA Developers.

⚠️ Note: Retracement to the old version may result in loss of internal memory, including photos and apps. Always backup before such a procedure.
