Firmware Xiaomi smartphone through Recovery with a locked bootloader is a task that seems impossible for most users. the manufacturer imposes strict restrictions: without unlocking the bootloader, official tools (Mi Flash, Fastboot) refuse to work, and attempts to circumvent the protection often end in brick (turning the device into a βbrickβ).
In this article, we will discuss all working methods of firmware through Recovery β from official recovery through Mi Recovery to the use of modified ones. TWRP-You will learn what files are needed for a particular model, how to avoid errors like E:footer is wrong or Error 7, and what to do if the phone does not turn on after the firmware. The procedure requires precise follow-up to instructions β even a small error can result in data loss or device breakdown.
Why Xiaomi is blocking the bootloader and can it be bypassed?
The bootloader is a security measure that Xiaomi has implemented to prevent unauthorized changes to the system partition. Officially unlocking is only possible through the official Mi Unlock tool, but it requires:
- π Linking the Mi Account to the device (with confirmation by SMS/email).
- β³ Expectations 7-360 days (depending on model and region).
- π± Connect to the Internet during the procedure.
However, the firmware through Recovery allows you to upgrade or restore the system without unlocking the bootloader, if you use the right files.
- π§ Mi Recovery (stock) β supports only official firmware in.zip format with a digital signature Xiaomi.
- π οΈ TWRP (Custom β allows you to install informal firmware, but requires pre-installing via Fastboot (which is not possible with a locked bootloader).
β οΈ Attention: Firmware through TWRP With a locked bootloader, Recovery is only possible if Recovery is already installed before locking or through exploits (e.g., for older models on Qualcomm).+ year, this method does not work.
The bottom line is that if the bootloader is locked, your only safe option is official firmware through Mi Recovery. All other methods involve risks and require deep technical knowledge.
What firmware can be installed through Recovery with a blocked bootloader?
With the bootloader locked, the device will only accept official firmware signed by Xiaomi, which is divided into two types:
| Type of firmware | Format | Appointment | Is it good for Recovery? |
|---|---|---|---|
| Fastboot (.tgz, .zip) | Archive with files for firmware through Mi Flash | Full flashing (including bootloader) | β No. |
| Recovery (.zip) | Archives for installation through recovery mode | Update/restore system without affecting bootloader | β Yes. |
| OTA (.zip) | Incremental update | Updating the current version to a new one | β Yes (for compatible versions only) |
Only Recovery ROM or OTA files are suitable for firmware through Recovery.
- π On the official Xiaomi website (select a version for your model and region).
- π Through third-party resources such as Xiaomi Firmware Updater (there are archives of old versions).
- π₯ From update packages received by air (OTA) β They can be extracted from the system cache (/cache).
β οΈ Note: Do not use firmware for other regions (e.g. Global instead of China) - this can lead to problems with the modem, camera or sensors. EU ROM, But they require an unlocked bootloader.
Critical detail: Firmware through Recovery does not affect the boot and recovery section, so it will not help if the problem is related to damage to the bootloader (for example, after a failed overclocking or rooting).
Preparation for Firmware: What to Do Before Starting?
Before you run through Recovery, follow the mandatory steps to minimize the risks:
Charge the battery to 50% or more |
Download the correct firmware (Recovery ROM) for your model |
Transfer the firmware file to the root of the internal memory or to SD-map|
Disable Mi Account protection (if enabled)|
Backup important data (photos, contacts, messages) |
Make sure the phone model matches the firmware (check in Settings) β The phone)-->
Pay special attention to firmware compatibility, for example, the firmware for the Redmi Note 10 Pro (sweet) will not work for the Redmi Note 10 (mojito), even if the models are similar.
- Open the settings β About the phone β version of MIUI.
- Tap 7 times on the MIUI version line to activate Developer Mode.
- Return to Settings β Additional β For developers and find the item Codename of the device.
If you are flashing a device with a damaged system (for example, after a reset or virus attack) and it does not turn on normally, use the button combination to log in to Recovery:
- π Turn off the phone.
- π Squeeze the power. + Volume up for 5-10 seconds.
- π± Release buttons when the Mi logo or Recovery menu appears.
π‘
If the device doesn't respond to the buttons, try plugging it into charging for 10 to 15 minutes, then try again. Sometimes a dead battery blocks the entrance to Recovery.
Step-by-step: Firmware through Mi Recovery
This method is suitable for all Xiaomi models with a locked bootloader, if you have an official firmware in.zip format for Recovery.
- Download the firmware for your model (see section above) and rename the file to update.zip (this will make it easier to navigate in Recovery).
- Transfer the file to the root of the internal memory or to the SD-Card (if the phone is not turned on, use it) ADB Sideload - see below).
- Go to Mi Recovery: 1. Turn off the phone. 2. Press <power button> + <volume up>. 3. Wait for the menu to appear in English/Chinese.
- Select a language (if available) and go to the Install update.zip to System menu (or similar).
- Confirm the installation and wait until the process is completed (usually 5-15 minutes).
- Restart the device via Reboot to System.
If the Recovery menu does not have the option to install update.zip, then your firmware is incompatible with the current version of Recovery.
- π Try to sew it. OTA-Update (if available for your version).
- π§ Use it. ADB Sideload (instruction below).
β οΈ Warning: If the phone has been stuck on the Mi logo for more than 10 minutes after you have been firmwareed, don't try to turn it off with the power button. Wait 20 to 30 minutes - sometimes the first download takes a long time. If nothing has changed after that period, repeat the firmware or try another file.
What if Mi Recovery doesnβt see update.zip?
Firmware via ADB Sideload (if Mi Recovery does not work)
ADB Sideload is an alternative way to install firmware through Recovery, which bypasses the restrictions on menu selection. It works even if Mi Recovery can't see. update.zip, but requires a computer and USB-cable.
You'll need:
- π₯οΈ Computer with installed ADB and Fastboot.
- π± USB-cable (preferably original).
- π The firmware in.zip format (same as for Mi Recovery).
Instructions:
- Download the firmware and rename it rom.zip (for convenience).
- Place the file in adb.exe folder (for example, C:\platform-tools\).
- Start your phone in Recovery mode and select Connect with MiAssistant (or ADB Sideload).
- Connect the phone to the computer.
- Open the command line in the adb folder and execute: Adb devices Make sure the device is identified (its serial number should appear).
- Enter the command to install: adb sideload rom.zip The process will take 5-15 minutes. Don't turn off the cable.
- Once completed, select Reboot system now.
If the adb sideload command is error: closed or device not found:
- π Check it out. USB-cable and port (try another cable or port) USB 2.0 instead of 3.0).
- π Reinstall Xiaomi drivers on your computer.
- π± Reboot your phone in Recovery and reconnect.

ADB Sideload is the only working method for firmware through Recovery if Mi Recovery doesnβt see the update.zip file or if it shows errors during installation.
Common mistakes and their solutions
When you run through Recovery with a locked bootloader, users often encounter errors, and here are the most common ones and how to fix them:
| Mistake. | Reason. | Decision |
|---|---|---|
| E:footer is wrong | A damaged or incomplete firmware file. | Download the firmware again and check its hash (MD5). |
| Error 7 | Incompatibility of firmware with the device (incorrect model or region). | Use firmware strictly for your model and region. |
| Couldn't mount /system | The system partition is damaged or there is not enough space. | Run the reset (Wipe Data) in Recovery before the firmware. |
| This package is for "xxx" devices; this is a "yyy". | The firmware is designed for another model. | Check the coded name of the device and download the correct firmware. |
If after firmware the phone does not turn on or loops on the logo:
- Try repeating the firmware with a full reset (Wipe Data in Recovery).
- If it doesnβt work, run the old version of MIUI, then upgrade to the new one.
- In extreme cases, use Mi Flash in Clean All mode (but this will require unlocking the bootloader).
Important: If the device has become a βbrickβ (no response to buttons, no computer-defined), the only way to recover is a service center or use of a computer. EDL-Mode (requires an authorized Xiaomi account and special equipment).
Can I use a custom firmware with a blocked loader?
Installing unofficial firmware (such as LineageOS, Pixel Experience or Xiaomi.EU) on a device with a locked bootloader is almost impossible.
- π Blocked boot ad does not allow you to modify the boot and recovery partitions that are necessary for the work of custom firmware.
- π‘οΈ Xiaomi uses DM-Verity, which blocks the launch of unsigned images.
- π§ Even if you can flash the system, the device will not boot due to a bootloop error.
Exceptions:
- π± Some older models (before 2019) on Qualcomm processors had exploits to bypass locks (e.g., via a Qualcomm processor). EDL).
- π Devices already installed TWRP (before blocking the loader) can accept custom firmware, but after restarting will return to the drain Recovery.
If you need custom firmware, the only legal way is to unlock the bootloader through the official Mi Unlock tool. Alternative methods (like using Fastboot with lock-bypass) often result in hard brick and loss of warranty.
π‘
If you need custom firmware features (such as no ads in MIUI or advanced settings), try the official firmware from Xiaomi.EU. They are based on the stock MIUI, but with remote bloatware and optimizations, but they still require an unlocked bootloader to install them.
