How to roll back the update on Xiaomi Redmi Note 7: the full guide

Owners of the popular smartphone Redmi Note 7 often face a situation when after the arrival of the next OTA-update, the device begins to work unstable. The battery drains faster, there are “glitches” of the interface or completely stop working properly familiar applications. In such cases, the only right solution is to return to the previous, more stable version of the MIUI shell.

The rollback procedure, or downgrade, requires careful follow-up and instructions. Wrong actions can lead to a bootloader lock or a system that is completely inoperable, but if you are careful, you can get your phone back to its previous speed and get rid of the changes that have been imposed.

In this article, we will take a look at all the methods available to return old firmware, how to prepare the device, where to download the necessary files and what risks exist, the main thing is to take your time and carefully read each step before it is executed.

Analysis of the reasons for returning the previous version of the software

Before you start technical manipulation, it is worth understanding why a new version of the software can cause problems. Often, Xiaomi developers optimize the system for new features, forgetting about the old models, which leads to the fact that the Redmi Note 7, released several years ago, ceases to cope with heavy updates.

One of the common reasons is a change in the algorithms of energy saving: after updating, the phone can aggressively “kill” background processes, which stops receiving notifications from messengers, users notice that autonomy decreases, and the heating of the case becomes noticeable even under light load.

There are also critical code errors that affect the operation of communication modules: Wi-Fi can shut down on its own, and the cellular network can disappear in areas of confident reception, and if you encounter such a situation, rolling back the system is the only way to return comfortable use of the gadget.

• 📉 A sharp decrease in battery life after installing the update.
• 📱 The appearance of system errors, freezes and spontaneous reboots.
• 📡 Deterioration of signal reception and operation of wireless communication modules.
• 🐛 Unstable operation of familiar applications and shell interface.

⚠️ Warning: Before starting the procedure, make sure to make a full backup of the data. During the rollback, all information from the internal memory will be permanently deleted.

Preparation of the device and search for the appropriate firmware

The most important step is to find the right version of the software, and you'll need a Recovery firmware (which has the.zip extension) rather than a Fastboot (the.tgz extension) if you plan to use the standard method through the recovery menu, which can be found on the official MIUI forum or the archives you've reviewed.

When selecting a file, focus on the region of your device. If you had a global version (Global), you can not install a Chinese (China) or Indian (India) without unlocking the bootloader. mismatch regions will lead to installation error or “bricking” the smartphone.

Make sure the battery is at least 60 percent, the process of writing data to the disk takes time, and a sudden power outage can interrupt a critical operation, and check the integrity of the downloaded file by comparing its checksum with the one listed on the site.

Once you download the file, rename it to update.zip and move it to the root folder of internal memory. Don't put the file in deep directories, the system may not see it in recovery mode.

Recoiling through the standard recovery menu

This is suitable for situations where you want to go to a neighboring firmware version or go back a step, but the bootloader is locked. The standard MIUI update mechanism has built-in protection, but it allows you to roll back if the file version is lower than the current one.

To start, go to the phone's settings. You need to activate the hidden feature. Open the About Phone menu and click on the MIUI version several times until "Additional Features Enabled" appears. Then go back to the main settings menu and select "Extended Settings."

In the list that opens, look for System Update. Click on the three dots in the top right corner and select Select firmware file. Find your prepared update.zip and confirm the selection. The system will check the file and suggest rebooting for installation.

If the system produces an error called “File Failure to Verify” or “Cannot Verify Update,” you are trying to install an older version than the current one, but the security is blocking this action, in which case you will need to unlock the bootloader or use special commands.

💡

If the standard method doesn’t see the file or forbids installation, try renaming the file to any other name and then back to update.zip. Sometimes this resets the system check cache.

Use Fastboot Mode and Mi Flash Tool

If the standard path is closed, you will have to use a more powerful tool, the Mi Flash Tool. This method requires an unlocked bootloader. If your bootloader is locked, first apply for unlock through the official Xiaomi website and wait for the code.

Download and install drivers ADB/Fastboot You'll also need a Fastboot firmware (.tgz extension) that you'll need to unpack into the root of the C disk to keep the path short, like the one you're going to use: C:\rom_redmi_note_7_global.

Turn off your phone and press down and power at the same time. When the bunny in the earpiece appears on the screen, plug the cable into your PC. Open Mi Flash, select the path to the firmware folder, and press the Refresh button. Make sure the device is identified.

At the bottom of the program, select the option clean_all. This will completely delete all data and install a clean system «clean_all_and_lock» It's dangerous if the firmware version is older than the one that was installed before, the phone will go into a bootloop.

⚠️ WARNING: When running through Fastboot, never turn off the cable. USB And don't turn off the computer. Interrupting the sector recording can permanently shut down the device.

Solving Common Errors When Systems Recoil

In the downgrade process, users often encounter a message that says, "Updated package verification failed." This means that the signature of the file does not match the expected one, which happens if you downloaded firmware for another region or a modified file from the forum.

Another problem is hanging on the logo. MI If the phone is hanging on the screensaver for more than 10 minutes, try entering Recovery mode. + Power) and make Wipe Data. If that doesn't work, you'll have to go through the Fastboot clean.

Sometimes the computer stops seeing the phone in Fastboot mode. In this case, check the Windows Device Manager. If there's a "Unknown Device" or exclamation point device there, reinstall the Xiaomi USB Driver drivers. Use the original cable that comes with the bundle, as cheap counterparts often only work on charging.

• 🔓 Verification error: check the firmware region and bootloader status.
• 🔁 Bootloop: Complete the Wipe All Data reset).
• 🔌 PC can't see phone: Replace USB-cable.
• 📉 Not enough space: free up the minimum 3-4 GB in internal memory before updating.
