In such cases, it is logical to return the old firmware - but the manufacturer does not provide official tools for rollback. Fortunately, there are workarounds, and in this article we will analyze all the current methods, including the nuances with the unlocked and locked bootloader.

This article is aimed at users with different levels of training, from beginners who hear about Fastboot for the first time, to experienced enthusiasts looking for the best way to roll back without losing data. If you are not sure about yourself, contact a specialist or use the safest method (via Recovery with the official package).

Why you might need to roll back firmware on the Redmi Note 7

Changing firmware to an older version is not a whim, but often a must-do. Here are the typical reasons Redmi Note 7 owners face:

• 🐢 Performance: New versions MIUI (especially global) can "brake" on the old iron, for example, after updating to MIUI 13/14 Users complain of hanging out when multitasking or launching a camera.
• 🔋 Autonomy: Optimizing energy consumption in fresh builds sometimes leaves much to be desired. The battery sits down in 4-5 hours instead of the usual 8-10.
• 🚫 Remote Features: Xiaomi regularly removes useful chips (for example, Game Turbo in its old form or settings) DC Dimming for AMOLED-screen).
• 🔒 Errors and bugs: Critical bugs like random reboots, problems with the Wi-Fi/Bluetooth System applications (Google Play Services, Mi Account).
• 🛡️ Security: In rare cases, a new firmware may contain vulnerabilities (e.g., problems with the bootloader after an update via a new firmware.) OTA).

Before you start rolling back, check if the reset will solve the problem (via Settings → About Phone → Resetting). If the lags and bugs remain, start choosing the rollback method. But remember: on models with a locked bootloader (most official devices), the rollback is possible only through the Fastboot with complete flashing and data loss.

Preparing for a rollback: what to do before the start

Regardless of the method you choose, preparation is a critical step, and if you skip one item, you risk losing data or getting a broken phone, and we start with the mandatory steps:

1. Create a backup copy: 📱 Application Data: Use Mi Cloud (enable sync in Settings) → Xiaomi account) or Google Drive (for contacts, photos, notes). 💾 Full Backup: For root users — TWRP + Nandroid Backup. without root, Xiaomi program ADB/Fastboot Tools (Backup mode). 📂 Manual Files: Copy folders DCIM, Downloads, Pictures on PC.

Check the bootloader version.

adb reboot bootloader

In the command line, type this command (the phone must be connected over USB with debugging enabled). If the answer is Device unlocked: false, the bootloader is locked.

Download the right tools.

• 🖥️ MiFlash Tool (official firmware utility via Fastboot).
• 🔧 ADB and Fastboot (for command line).
• 📦 Firmware archive (select the version strictly for lavender!).

For example, if your Redmi Note 7 was running MIUI 12.5 and you upgraded to MIUI 13, you can only roll back to the version that is not lower than the current Android number (for example, Android 11 to Android 10 can not roll back due to anti-rollback).

⚠️ Note: If you use banking applications (Sberbank, Tinkoff, etc.), after a rollback, they may stop working due to changes in security certificates.

Method 1: Recovery (the safest way)

This method is suitable if:

• ✅ You have an official firmware (not customized).
• ✅ You are going to go back to the same version. MIUI (for example, from 12.5.3 to 12.5.1).
• ✅ The bootloader is unlocked or you are ready to unlock it.

The advantage of the method is that it has minimal risk of bricking, because the firmware is installed through the standard Recovery, but it will not work if:

• 🚫 You are trying to upgrade to an older version of Android (e.g. 11 to 10).
• 🚫 You have custom Recovery (for example, TWRP), but not a good firmware.

Step-by-step:

1. Download the full firmware package (.zip format) from the Xiaomi Firmware Updater. the file name must contain the lavender and version. MIUI (for example, miui_LAVENDERGlobal_V12.5.1.0.RFGMIXM_...).
2. Rename the file to update.zip and transfer it to the root folder of the phone’s internal memory (not to folders!).
3. Turn off the phone. Press Volume up + Power to enter Recovery.
4. In the Recovery menu, select Install update.zip to System (navigation – volume buttons, choice – power button).
5. Confirm the installation and wait for the completion (5-10 minutes).

If after the reboot the phone is stuck on the Redmi logo for more than 15 minutes, reset the settings through the same Recovery (Wipe Data).

💡

If Recovery doesn’t have Install update.zip, you have custom Recovery, in which case select Install, specify the path to update.zip, and make Wipe Cache after installation.

Method 2: Fastboot firmware (for a locked bootloader)

This is the only working method for locked bootloaders, but it requires complete flashing and erases all data.

• 🖥️ Windows PC (Mac/Linux Not supported by MiFlash).
• 🔌 Original. USB-cable (better from the set).
• 📦 Firmware in.tgz or.zip format (download Fastboot version!).

Algorithm of action:

1. Unpack the archive with firmware in a folder without Cyrillic characters (for example, C:\MIUI\lavender_fastboot).
2. Install the MiFlash Tool and Xiaomi drivers (if the PC can’t see the phone in Fastboot mode).
3. Turn off the phone. Press Volume down + Power to enter the Fastboot (a screen with a rabbit and the words Fastboot).
4. Connect your phone to your PC. In MiFlash, press Select and specify the folder with the unpacked firmware.
5. At the bottom, select Clean All mode and press Flash.
6. Wait until it's finished (the process will take 5-15 minutes) and the phone will reboot automatically.

If MiFlash is making a mistake flash_all_lock.bat So failed:

• 🔹 You did not download the firmware for your model (check the code name lavender).
• 🔹 The bootloader is locked and the firmware is not signed for your region (you need to take Global or EEA version).
• 🔹 On the way to the folder with firmware there are gaps or Cyrillic.

⚠️ Note: After Fastboot, the phone may require a link to your Mi Account if you previously enabled Mi Cloud Lock. Make sure you remember your username and password!

Method 3: Recoil through TWRP (for power users)

This method is suitable for those who already have custom Recovery (TWRP) installed and unlocked the bootloader.

• ✅ You can roll back to any version (within the same Android).
• ✅ Data is saved (if you do not use Wipe).
• ✅ Supports custom firmware (e.g. Pixel Experience, LineageOS).

Instructions:

1. Download firmware in.zip format (for example, from SourceForge for Redmi Note 7).
2. Reboot your phone to TWRP (adb reboot recovery command or Volume up + Power buttons).
3. In TWRP, click Install, select the downloaded file and swipe for confirmation.
4. After installation, run Wipe Cache/Dalvik (required!).
5. Reboot the system (Reboot System).

If the phone does not load after rollback:

• 🔹 Try to stitch the core (boot.img) Fastboot: Fastboot Flash boot boot.img
• 🔹 Delete the folder. /data/system/package_cache through TWRP (Sometimes it helps when you hang on the logo).

How to avoid mistakes when rolling back firmware

Even when following instructions, users often encounter problems, and here are the typical mistakes and how to prevent them:

1. Incompatible firmware: Download files only for the Redmi Note 7 (lavender) model. The firmware for the Redmi Note 7 Pro (violett) or Redmi Note 8 (ginkgo) will not work!

If you see an error, this package is for "lavender" devices; this is a.

• 🔹 You downloaded firmware for another model (check the file name).
• 🔹 The updater-script file inside the archive indicates the wrong device (you can fix it manually, but it is for experienced users).

💡

Always check the hash amount (MD5) of the downloaded firmware! Compare it to the official Xiaomi Firmware Updater website.

What to do if the phone does not turn on after rollback

If the screen is black or the phone is stuck on the logo, don't panic. 90 percent of the time, the device can be restored.

1. Wait 15-20 minutes: The first download after the firmware can take a long time (especially if you did Wipe Data).
2. Try logging in to Recovery: Press Volume Up + Power. If you get to Recovery, run Wipe Data and restart.
3. Fastboot: If Recovery is not available, then swipe the same firmware again through MiFlash in clean all mode.
4. Use it. EDL-Mode (extreme): If the phone doesn't respond to buttons, connect it to the PC, press Volume up + Loud down and insert USB-In the Device Manager should appear Qualcomm device HS-USB QDLoader 9008.

• 🔹 Have you used a firmware from third-party developers (for example, with a XDA) non-compatibility-check.
• 🔹 Is your phone memory damaged (try flashing another version) MIUI).
