Why might a MIUI upgrade require a rollback?

Smartphone manufacturers rarely acknowledge the problems of new firmware, but Xiaomi users regularly face:

• 🔋 Increased battery consumption - background processes of the new MIUI They can consume up to 30% of their charge per night.

According to the statistics of the 4PDA and XDA Developers forums, most often a rollback is required after updates to MIUI 12.5→13 and Android 10→11. The reason is a change in the logic of the memory management system (RAM), which causes applications to spontaneously close or restart.

⚠️ Attention: Retracement to the version MIUI older than the one installed on the smartphone when you buy, can lead to loss IMEI (This will make it impossible to make calls and mobile Internet. Before the procedure, check the current version in Settings → The phone. → Version. MIUI.

Method 1: Recoil through Fastboot (official method)

The most reliable method, but requires an unlocked bootloader and PC with ADB/Fastboot drivers installed. Suitable for rollbacks to any official version of MIUI, including older builds.

Step-by-step:

1. Download the firmware for Fastboot (file with.tgz extension).
2. Unpack the archive in a folder on the disk C:\ (for example, C:\miui_fastboot).
3. Turn off your smartphone and press Volume Down + Power to enter Fastboot mode.
4. Connect your phone to your PC and launch the file flash_all.bat (for Windows or flash_all.sh (for Linux/Mac).

It takes 5-10 minutes. When it's done, it automatically restarts. Importantly, the first run after the firmware can take up to 15 minutes -- don't interrupt it!

⚠️ Note: If the smartphone is stuck on the Mi logo after rollback, then the firmware is incompatible with your version of the bootloader. Solution: run the anti-rollback patch (see the error section).

💡

Before you run through Fastboot, turn off driver signature verification in Windows. To do this, restart your PC in the check-out mode (click F8 when booting and select "Disable Mandatory Driver Signature Verification").

Method 2: Recovery (without PC)

If you don't have access to a computer, you can try rolling back through a standard Recovery, which is less reliable, because not all versions of MIUI support downgrades through the air.

Algorithm of action:

1. Download the firmware for Recovery (file with.zip extension) to your phone.
2. Rename the file to update.zip and move it to the root of internal memory.
3. Go to the recavery: turn off the phone, then press Volume up + Power.
4. Select Install update.zip to System (navigation – volume buttons, confirmation – power button).

If there's no such item on the Recaveri menu, your version of MIUI doesn't support it, so you'll have to use Fastboot or TWRP.

Method 3: Recoil through TWRP (for power users)

TWRP Castom Recovery allows you to flash any version of MIUI, including modified assemblies.

• 🔓 Unlocked loader.
• 📱 Established TWRP (The version should support the Redmi Note 7).
• 📂 Backup copy of the persist section (or you will lose it) IMEI).

Instructions:

1. Download the firmware in.zip format and place it on the memory card.
2. Go to TWRP (Put Volume Up + Power on your phone).
3. Backup of the current system (Backup) → Select the System, Data, Boot sections).
4. Click on Wipe → Advanced Wipe and tick Dalvik, Cache, System, Data.
5. Sweep through Install and restart.

After the reboot, you may need to re-assign your Mi Account, as the data reset removes all authorizations.

💡

Use TWRP only if you are confident in your actions. An error in choosing a partition to wipe can result in loss of IMEI or inoperability of the NFC module.

Even with the correct following of the instructions, problems can arise, and here are the most common ones and ways to fix them:

If after the rollback stopped working mobile networks, check the settings APN In Settings → SIM-maps and mobile networks → Access points (APN). Often they are reset to standard ones that are not suitable for your operator.

Data recovery after rollback

If you have backed up via Mi Cloud or locally, you can recover your data in a few steps:

1. After the first start of the new firmware, skip the setting (click Skip on the welcome screen).
2. Connect to Wi-Fi and log in to your Mi Account.
3. Go to Settings → Additional → Recovery and Reset → Restore with Mi Cloud.
4. Select the right backup and wait for the process to be completed.

For local backups, use the backup.ab file (located in the MIUI/backup/AllBackup folder). Transfer it to your phone and restore it through Settings → Additional → Backup.

⚠️ Note: Do not restore system application data (e.g. com.android.providers.settings) – this may lead to conflicts with the new firmware, SMS.
