However, the upgrade process on this device has nuances, from Android version restrictions to specific installation errors.

In this article, you will find all the current ways to update MIUI to Redmi 7A (including manual method through Recovery), deal with typical problems (for example, the error "Cannot verify update") and learn how to check the compatibility of the firmware with your model. We will also tell you what to do if the smartphone stopped turning on after a failed update – this information is critical for owners of devices with an unlocked bootloader.

Before updating, you need to know exactly which firmware is installed on your device, which will help you avoid errors when choosing a file for manual installation and understand whether your version is relevant.

To get a version of the software:

1. Open Settings (the gear icon on the main screen).
2. Scroll down and select About Phone.

4. To check the Android version, click several times on the Android version bar and more information will appear.

Look for the code name for the device (pine for Redmi 7A), which is useful when searching for custom firmware, and check the firmware region (Global, China, EEA) - this is important for compatibility.

2. Automatic update of MIUI through settings

The easiest and safest way to do this is to upgrade to an over-the-air (OTA) update, which is suitable for most users if:

• 📶 The device is connected to stable Wi-Fi (update weighs 1.5-2.5 GB).
• 🔋 Battery charge of more than 50% (80 recommended%+).
• 📱 There is enough free space on the phone (at least 3 GB on the system partition).
• 🔒 No root rights or custom recaveri (in this case) OTA may not work).

Step-by-step:

1. Go to Settings → About the phone → System update.
2. Click Check Updates. If the update is available, a notification will appear.
3. Click Download and wait until the download is complete (don’t interrupt the process!).
4. After downloading, click Install and confirm the reboot.

The device will restart to Restore mode, where the update will be installed, which takes 5-15 minutes. Do not remove the battery and do not press the buttons at this time!

⚠️ Note: If after clicking "Install" the phone hangs on the logo MIUI For more than 20 minutes, it's a sign of firmware incompatibility, in which case force the device to restart (press the power supply). + Volume up for 10 seconds and try the manual method.

Manual updates via Recovery: when and how to use

Manual installation of firmware through Stock Recovery (standard recovery) is required if:

• 🔄 Automatic updates do not find a new version (for example, due to regional restrictions).
• 📦 You downloaded the firmware from the official Xiaomi website and want to install it manually.
• 🔧 Previous attempt OTA-The update ended in error.

Important: This method does not require unlocking the bootloader, but is only suitable for official firmware in.zip format for your model (pine).

Instructions:

1. Download the firmware from Xiaomi’s official website (select Redmi 7A, region and stable version).
2. Rename the file to update.zip and move it to the root folder of internal memory (not to folders!).
3. Turn off the phone, then press Power + Volume up to enter Recovery Mode.
4. In the Recovery menu, select the language (if available), then: Install update.zip to System One → confirm the selection.
5. Wait until the installation is completed (the progress bar should reach 100%).
6. Select Reboot to System to restart.

⚠️ Note: If you downloaded firmware for another region (e.g. China instead of Global), Google services may disappear after installation, and the system language will change to Chinese. To return Google services, you will need to manually install GApps through a custom recaveri.

💡

If you have a "Cannot verify update" error when you manually install it, try renaming the firmware file to update.zip (that's right, no numbers at the end) and repeat the process, which solves the problem 80 percent of the time.

Update via Fastboot: for power users

The method via Fastboot is used if:

• 🔓 You have unlocked the bootloader (bootloader).
• 📥 You need to install firmware that is not installed through Recovery (for example, downgrade version).
• 🛠️ The device "bricked" (not turned on) after a failed update.

This method will require:

• 🖥️ Computer with Xiaomi drivers installed and Mi Flash Tool.
• 🔌 Cable USB (preferably original).
• 📁 Firmware in.tgz or.zip format for Fastboot.

Step-by-step:

1. Download Fastboot firmware for Redmi 7A (the file will weigh ~2.5 GB).
2. Unpack the archive in a folder on your computer (for example, C:\MIUI\pine_fastboot).
3. Turn off the phone and press Power + Volume down to enter Fastboot Mode (a hare in a hat-out-of-the-box will appear).
4. Connect your phone to your PC and start the Mi Flash Tool.
5. In the program, click Select, specify the folder with the unpacked firmware, then select Clean All (complete cleaning) or Save User Data (data saving).
6. Press Flash and wait until it is completed (10-15 minutes).

Once the firmware is successful, the phone will automatically restart. The first run can take up to 10 minutes -- that's okay.

5. Typical update errors and their solutions

Even when following the instructions, Redmi 7A users encounter errors, and here are the most common ways to fix them:

If the phone stopped turning on after the update (the so-called “brick”), try:

1. Log in Fastboot Mode (Power + Volume Down) and flash the device through the Mi Flash Tool.
2. If Fastboot is not available, use EDL Mode (Emergency Mode) with the Qualcomm 9008 box (requires soldering skills).

💡

If Google's Play Market (Gmail) services are missing after the update, you've installed Chinese firmware, so you can run the Global version through Fastboot or install GApps manually through TWRP.

6.How to roll back the MIUI update to the previous version

Sometimes the new MIUI version is worse than the old one: it has lags, it goes down faster, or it loses functions, and then you can do a downgrade, a rollback to the previous firmware.

For this:

1. Download the desired version of MIUI from the official archive.
2. Rename the file to update.zip and place it in the root of the memory.
3. Log in to Recovery Mode and select Install update.zip.
4. Confirm the installation and wait for completion.

Important: When downgrade, be sure to reset (Wipe Data in Recovery), otherwise errors in the system may occur. Also note that rolling back to a version older than the one installed out of the box can lead to problems with the anti-rollback module.

⚠️ Attention: On Redmi 7A recoiling MIUI 12.5 on MIUI 11 or lower – this will lock the device (reflashing through the device is required). EDL). Only recoils within one major version are allowed (for example, with a MIUI 12.5.1. MIUI 12.5.0).

• 📱 LineageOS (Android 10/11) — pure Android MIUI.
• 🔄 Pixel Experience – firmware with Google Pixel interface.
• 🛡️ Havoc-OS - customizable firmware with advanced settings.

The advantages of custom firmware:

• ✅ Support for new versions of Android (up to Android 11 for Redmi) 7A).

If you decide on custom firmware, follow this algorithm:

1. Unlock the bootloader through the Mi Unlock Tool (it will take 7-14 days to wait for permission from Xiaomi).
2. Install custom TWRP recavators for Redmi 7A (you can download on the official website).
3. Backup your current firmware in TWRP (Backup → Select Partitions → Swipe to Backup).
4. Sweep through custom firmware and GApps (if you need Google services).
