Why Users Want to Reverse Xiaomi Firmware and When to Really Need It
MIUI updates often bring not only new features, but also unpleasant surprises, from sudden bugs to critical performance declines. According to surveys among Xiaomi owners, one in five users at least once thought about rolling back to the previous version of the firmware after a failed update. But before rushing to extremes, it is important to understand that rollback is not a panacea, but a forced measure with its own risks.
The main reasons for returning to the old version of MIUI are:
- ๐ข Slowdown โ the firmware started to โbrakeโ after the update (especially relevant for budget models like Redmi Note 8 or Poco X3)
- ๐ Increased battery consumption โ Autonomousity dropped by 20-30% for no apparent reason
- ๐ Critical bugs: sensors fail, communications go missing, apps crash
- ๐ Undesirable changes: Deleted a favorite feature (e.g., Second Space in MIUI14)
- ๐ฑ Incompatibility with important applications (banking services, games)
However, before rolling back, check:
- Reset to factory settings via Settings โ About Phone โ Resetting โ Sometimes it solves problems without losing data
- Install all available patches in Settings โ Update Center โ bugs could fix after
- Check the forums (4PDA, XDA) for alternative solutions for your model
You should only consider rollbacks if other methods have not worked, and remember, the procedure will reset all the data on the phone if you don't backup in advance.
Method 1: Recovery (for power users)
The most common way to get your old firmware back is to use Recovery mode, which is suitable for most Xiaomi, Redmi and POCO models, but requires pre-preparation. An important condition is that you must have a bootloader unlocked (if not, see Method 4).
Step-by-step:
- Download the official firmware for your model from MIUI Download. Choose the Recovery ROM version (not Fastboot!)
- Rename the file to update.zip and place it in the root directory of the phoneโs internal memory
- Turn off the device. Press Volume up + Power to enter Recovery
- From the Recovery menu, select Install update.zip to System.
- Confirm the installation and wait for completion (10-15 minutes)
Download the correct version of Recovery ROM|Rename the file to update.zip|Put the file in the root of the memory|Charge your phone at least to 50%|Unlock bootloader (if required)-->
โ ๏ธ Warning: If after rollback the phone is stuck on startup the MI logo for longer than 20 minutes:
- Forced reboot it with a clamping Power + Volume down for 15 seconds
- If it doesnโt work, repeat the procedure or try the Fastboot method (Method 2).
What if Recovery doesnโt see update.zip?
Method 2: Recoil through Fastboot (the most reliable way)
Fastboot is considered the most reliable, but also the most complex, and it works for all Xiaomi devices, including those that have a system damaged, youโll need a computer with ADB/Fastboot drivers installed and the original USB- cable.
Algorithm of action:
- Download Fastboot ROM for your model from the official website. the file will be in.tgz or.zip format.
- Unpack the archive into a folder on your computer (no Cyrillic path!) and inside it should be an image folder with firmware files.
- Connect your phone in Fastboot mode: Turn off the device, then press Volume Down + Power
- Open the command line in the firmware folder and execute the command: fastboot flash all (new models may require fastboot update name file.zip)
- Wait until it is completed (the process will take 5-10 minutes).
| Xiaomi model | Features of Fastboot firmware | Is it necessary to unlock the bootloader? |
|---|---|---|
| Redmi Note 11/Pro | Use the fastboot update command instead of flash all | Yes. |
| POCO F3/F4 | The archive must have a flash_all_lock.bat file to lock the bootloader. | Yes. |
| Mi 11 Ultra | You need to disable the antirollback check (see Method 5) | Yes. |
| Redmi 9A/9C | Supports firmware without unlocking bootloader (official ROM only) | No. |
โ ๏ธ Warning: Models with a MediaTek processor (e.g., Redmi Note 10S) may require an additional SP Flash Tool. A standard fastboot is sufficient for Qualcomm devices (most flagships).
๐ก
If the fastboot command is not recognized, install the Android SDK platform or use the portable version of ADB/Fastboot from XDA Developers.Tool link: [XDA ADB/Fastboot Tools](https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot.2317790/)
Method 3: Recoil through the MI Flash Tool (for Windows)
MI Flash Tool is Xiaomi's official Fastboot firmware utility, which automates the process and reduces the risk of errors, and is suitable for all models, but requires an unlocked bootloader.
Instructions for use:
- ๐ฅ Download and install MI Flash Tool (version no lower than 2023.4.18.0)
- ๐ Download Fastboot ROM for your model and unpack it into a folder without Cyrillic.
- ๐ Connect your phone in Fastboot mode (as in Method 2)
- ๐ฑ๏ธ In MI Flash Tool, press Select, specify the firmware folder, then Refresh
- โ๏ธ At the bottom, select Clean all (full reset) or Clean all and lock (reset + lock bootloader)
- ๐ Press Flash and wait until it is completed (green tick)
The advantages of the MI Flash Tool:
- โ Automatic Integrity Check of Firmware Files
- โ Support for all official Fastboot ROM from Xiaomi
- โ Ability to lock bootloader after firmware (important for security)
๐ก
MI Flash Tool is the only officially supported way Xiaomi firmware through Fastboot. Using third-party tools (such as SP Flash Tool) can lead to loss of warranty.
Method 4: Unlock the bootloader before rolling back
Most rollback methods require an unlocked bootloader. If you have never unlocked it before, you will have to go through the official procedure through the Mi Unlock Tool. Importantly, Xiaomi has introduced unlock restrictions for new devices (released after 2022).
How to unlock bootloader:
- Link your Mi-account to your phone in Settings โ Xiaomi account
- Activate USB debugging in Settings โ About Phone โ MIUI version (click 7 times), then in Additional โ For Developers
- Download Mi Unlock Tool and log in to the program
- Connect your phone in Fastboot mode and follow the instructions in the utility
- Wait for the SMS with the confirmation code (may come in 3-7 days for new devices)
โ ๏ธ Warning: Starting with MIUI 14, Xiaomi has tightened the rules:
- For devices under 30 days, unlocking is prohibited
- For devices 30-60 days requires 72 hours of waiting after the account is linked
- On some models (for example, Xiaomi 13T) unlock is completely blocked by the manufacturer
Bypassing Unlocking Restrictions for New Devices
Method 5: Bypassing the anti-rollback (for advanced users)
Since MIUI 12, Xiaomi has implemented an anti-rollback system that blocks rollbacks on older firmware versions. If you see an anti-rollback check fail error, this section is for you.
Ways to bypass Anti-Rollback:
- ๐ง Modified firmware: Some custom ROM (e.g. Xiaomi.eu) have anti-rollback disabled. Only download from trusted sources!
- ๐ ๏ธ Firmware editing: Delete the antirollback.db file from the firmware archive (requires knowledge of working with 7-Zip and Notepad++)
- ๐ Use EDL- Mode: Firmware through emergency mode with Mi Flash Pro (power users only!)
โ ๏ธ Warning: Bypassing an antirollback can lead to:
- Loss of warranty on the device
- Unstable operation of the system (accidental reboots, overheating)
- Problems with future updates (the phone may refuse to accept new firmware)
On Xiaomi 12/13 series and Redmi K50, bypassing the antirollback often results in hard brick (irreparable damage), as these devices use Secure Boot 3.0 protection.

Before trying to bypass the anti-rollback, check your model at the [XDA Anti-Rollback Database](https://forum.xda-developers.com/t/xiaomi-anti-rollback-protection-list.4268957/).
What to do after a successful firmware rollback
You've brought back the old version of MIUI, but the work doesn't end there.
System inspection:
- ๐ฑ Reboot your phone and check the basic functions: calls, internet, camera
- ๐ Record battery life โ if the discharge is too fast, calibrate (discharge to 0%, charge to 100% without interruption)
- ๐ฏ Make sure the issues you were pulling back for are gone.
Data recovery:
- ๐ฒ Restore Contacts and SMS via Settings โ Google โ Restore
- ๐ท Move your photos/video from your computer or cloud (donโt use Mi Cloud โ it can automatically update your firmware!)
- ๐ฎ Manually reinstall applications โ automatic backups (e.g., via Titanum Backup) may contain incompatible data
Protection against re-updating:
- ๐ซ Turn off automatic updates in Settings โ About Phone โ System Update โ โ๏ธ โ Auto Update
- ๐ If the bootloader is unlocked, lock it back through fastboot oem lock (this will protect against random firmware)
- ๐ก๏ธ Install Magisk and Disable Force Encryption if you plan to use custom firmware
๐ก
Once the firmware is rolled back, never recover data from MIUI backups! They contain system settings of the old version that can cause conflicts. Use only backups of individual applications (for example, Swift Backup for user data).
