Xiaomi’s firmware is a process that can both bring a brick back to life and turn a working smartphone into a useless piece of plastic. The difference between success and failure is often in the little things: a mischosen version of MIUI, an interrupted connection to a PC, or ignoring the bootloader’s unlocking. This article will not just list the ways to firmware, but explain what is right for your situation, how to avoid typical mistakes, and what to do if something goes wrong.
We’ll look at all the current methods, from the safest (update over the air) to the most risky (handheld firmware via Fastboot), and focus on unlocking the bootloader, a mandatory step for most methods that many users miss, and you’ll find a firmware compatibility table with Xiaomi models, a training checklist, and answers to questions that arise after a failed firmware.
If you've never flashed a smartphone before, start with "What firmware to choose." Power users can immediately go to the instructions on Fastboot or firmware through Recovery, and those who have already encountered errors will be helped by a block with common problems and their solutions.
What Xiaomi firmware method to choose: a comparison of methods
The choice of firmware method depends on three factors: the purpose (update, downgrade, recovery), the state of the device (if it works, if the bootloader is unlocked) and the model (some Xiaomi smartphones have limitations).
| Method | When to use | Do you need to unlock the bootloader? | Risk of "bricking" | Are the data stored? |
|---|---|---|---|---|
| OTA (over the air) | Update of the current version of MIUI | No. | Minimum | Yes. |
| Recovery (through stock recovery) | Recovery after failure, installation of official firmware | No (but I need an official firmware) | Low. | No (unless you do the wipe) |
| Fastboot (via PC) | Installation of custom firmware, downgrade, unlocking | Yes. | High-pitched | No (full reset) |
| EDL (Emergency mode) | Recovery of bricks if other methods do not work | Yes (and Mi Account authorization) | Very tall. | No. |
For most users, the best option is to upgrade through Recovery — it does not require unlocking the bootloader and is suitable for restoring the system after crashes. Exception: if your device is already unlocked and you want to install custom firmware (for example, LineageOS), Fastboot is not necessary. EDL is only a last resort — it requires authorization through a Mi Account and can lead to complete loss of data.
⚠️ Note: Firmware via Fastboot or EDL On devices with a locked bootloader, you will cause an anti-rollback error and possible loss of warranty. → The phone. → Version. MIUI (Press 7 times on "Core Version").
Preparation for firmware: what to do before the beginning
Regardless of the method chosen, preparing the device reduces the risks by 3 times.
- 🔋 Charge your smartphone to at least 60% when running through Fastboot or EDL The device should not turn off – it is guaranteed to turn it into a brick".
- 📱 Back up. Even if the firmware promises to save data, a failure can wipe everything out. Use Mi Cloud, Google Drive, or TWRP (if established).
- 🖥️ Prepare the PC. For Fastboot and EDL You will need Qualcomm or MediaTek drivers (depending on the processor), as well as Mi Flash Tool or fastboot utilities.
- 🔗 Download the right firmware. Xiaomi has 3 Firmware type: Recovery ROM — for installation via stock recovery (.zip file). ROM — for firmware through PC (folder with.img files). Global/China/EU ROM — The scaling area (set the one that was originally!).
Where do I download firmware? Official sources only:
- The official MIUI Downloads website (choose your model!)
- Xiaomi.eu Forum (for European firmware).
- Telegram chats (such as Xiaomi Firmware Updater) are for batch files and unofficial builds.
Downloaded the firmware for your model (check in Settings → About phone → Model)
Charged the phone ≥60%
Backup of contacts, photos and applications
Installed ADB/Fastboot drivers on PC (for Windows – Platform Tools)
Disabled antivirus (it can block firmware files)
Connected the phone to the PC and checked detection (adb device team)
-->
If you are running an informal build (like Pixel Experience), check out:
- Compatible with your model (see XDA Developers themes).
- The presence of bugs (such as a broken NFC or camera)
- Requirements for MIUI version (some custom firmware requires a specific stock version as a base).
💡
If you're flashing the Redmi Note 10 Pro or a new model on the Snapdragon 8 Gen, check out the anti-rollback (ARB) version. Installing the old firmware on the new device will lock it permanently!
Unlocking the bootloader Xiaomi: without it anywhere
Most firmware methods (except OTA and Recovery with official firmware) require an unlocked bootloader. Xiaomi blocks it by default to protect against viruses and unofficial firmware. Unlocking erases all data and requires binding to a Mi Account.
Here's how to do it:
- Link your Mi Account to your phone: Go to Settings → Mi Account. Sign in to your account (if not, sign up). Activate the "Find Device" option (this is a must!).
- Connect your phone to your PC and enable USB Debugging (Settings → About Phone → MIUI Version → Press 7 times on MIUI Version, then go back to Settings → Additional → For Developers).
- Download Mi Unlock Tool from the official website and run it on PC.
- Follow the program instructions: Log in to the same Mi Account as on your phone. Connect your phone in Fastboot mode (turn off your phone, then press Volume Down + Power) Wait for the check (may take up to 72 hours for new accounts!).
⚠️ Note: Once the bootloader is unlocked, Xiaomi may block some features, such as Mi Pay or Widevine L1 (This means that Netflix will not be working in the HD). Also unlocking resets the device to factory settings.
If the Mi Unlock Tool is running a "Couldn't unlock" or "Waiting for device" error, check:
- The last version of the utility (must be the last).
- Fastboot drivers on PC (try reinstalling through Google USB Driver).
- Account status (new Mi accounts can’t unlock the bootloader right away – you have to wait 3-7 days).
What if the Mi Unlock Tool can’t see the device?
Xiaomi firmware via Fastboot: step-by-step instructions
This method is suitable for installing official and custom firmware, but requires an unlocked bootloader. We will use the Mi Flash Tool for Windows.
What you need:
- Fastboot ROM firmware (.tgz file or folder with.img).
- Mi Flash Tool.
- Qualcomm or MediaTek drivers (depending on your phone’s processor).
Firmware steps:
- Run the Mi Flash Tool on behalf of the administrator.
Press "Flash"
After successful firmware, the phone will restart. The first launch can take up to 10 minutes - don't turn it off or press the buttons!
1. Repeat the firmware with a different mode (Clean all instead of Save user data).
2. Swipe through EDL (if the device does not respond at all).
3. check whether the firmware is suitable for your model (for example, Redmi Note 11 has several modifications: spes, fleur, etc.).

Firmware through Recovery: the safest way
This method does not require unlocking the bootloader and is suitable for installing official updates or restoring the system after a crash.We will use stock Recovery, not TWRP (for custom firmware you need TWRP, but this is a separate topic).
What you need:
- Firmware in Recovery ROM format (.zip file).
- A memory card or PC for transferring a file.
Instructions:
- Download the firmware for your model from the official website.
- Transfer the.zip file to your phone: Either through a memory card (put in the root). or through ADB Sideload (if the phone doesn't turn on but goes into Recovery).
Get in Recovery.
1. Turn off the phone.
2. Press <Loud up button> + <Power button> before the Mi logo appears.Choose a language
Click "Install update.zip"
Select a firmware file
Wait till it's over.
If the firmware is interrupted or there is an error E:footer is wrong, check:
- Integrity of the downloaded file (compare the MD5 hash with the official one).
- File name (you should update.zip if you transfer it to a memory card).
- Free space on the phone (needs a minimum of 4 GB).
💡
If Recovery doesn't have "Install update.zip," your firmware is too old. Update it first via OTA or Fastboot, then try again.
Common Mistakes in Xiaomi Firmware and Their Solutions
Even with the correct instructions, errors can occur, and here are the most common ways to correct them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Couldn't unlock the Mi Unlock Tool | Mi Account is not linked to a phone or new account (less than 7 days) | Wait 3-7 days, link the account again, check "Find the device" |
| Anti-rollback check fail | Trying to install the old firmware on a new device | Just make a new version. MIUI (check ARB-The version of fastboot getvar anti) |
| This package is for "xxx" devices; this is a "yyy" | The firmware is not suitable for your model. | Download the firmware specifically for your model code (for example, Redmi Note 10 Pro has a code sweet) |
| The phone does not turn on after firmware (black screen) | Mi Flash Tool or Misfunction in Firmware | Repeat the firmware in Clean All mode or run through EDL |
| E:unknown command [log] error in Recovery | A damaged firmware file or unofficial recovery | Check the hash of the file, download the firmware again, use stock Recovery |
If your device has turned into a brick (no button response, no Recovery or Fastboot), try:
- Swipe through EDL (requires authorization of the Mi Account from the official partner).
- Use testpoint (for devices on Qualcomm – you need to close contacts on the board).
- Contact the service center (if there is no experience in soldering).
⚠️ Note: On Xiaomi devices with MediaTek processor (e.g. Redmi) 9A, Poco M3) firmware EDL Without authorization, it can lead to a complete lockdown. IMEI. In this case, the phone can be restored only in the official service with access to the Mi Authorized Account.
