How to flash Xiaomi Redmi Note 7 through MiFlash: a complete guide to unlock the bootloader

Why Redmi Note 7 owners choose firmware through MiFlash

Xiaomi Redmi Note 7 (codenamed lavender) remains popular even years after its release โ€” its robust Qualcomm Snapdragon 660 platform and balanced specs allow the device to compete with modern budget models. However, over time, users face slowdowns, MIUI bugs or the desire to install custom firmware. This is where the official MiFlash tool, a utility from Xiaomi, allows you to โ€œcleanโ€ reflash the device through EDL (Emergency Down Mode) mode, comes to the rescue.

Unlike updates over the air or via Fastboot, firmware through MiFlash has a number of advantages:

  • ๐Ÿ”„ Brick recovery โ€“ if the smartphone doesnโ€™t turn on or gets stuck on the Mi logo, MiFlash is often the only solution.
  • ๐Ÿงน Clean installation โ€“ all user data is deleted, factory settings are returned without traces of previous firmware.
  • ๐Ÿ”’ Bypassing locks โ€“ helps with failures after unsuccessful attempts to get root or install TWRP.
  • โšก Downgraid version MIUI โ€” the ability to roll back to a more stable build if the new firmware is working with errors.

But it is important to understand that the process requires unlocking the bootloader and is fraught with risks when you do the wrong thing. This article will help you avoid errors and execute the firmware the first time.

Preparation for firmware: what to do before the start

Before you start running your firmware through MiFlash, there are a few critical steps that need to be taken: neglecting them can lead to data loss, device lockdown, or even physical damage (in rare cases), starting with the most important thing: unlocking the bootloader.

Xiaomi has a security policy that locks the bootloader by default, and to flash the device through MiFlash, it must be unlocked in the official way:

  1. Link your Mi Account to your device in Settings โ†’ Xiaomi Account.
  2. Go to Settings โ†’ About Phone โ†’ MIUI version and tap 7 times on the line to activate Developer Mode.
  3. Return to Settings โ†’ Additional โ†’ For developers and enable OEM Unlock and USB Debugging.
  4. Download the official Mi Unlock Tool and follow the unlock instructions (it may take up to 720 hours to wait!).

โš ๏ธ Note: If you have previously unlocked the bootloader, but more than 30 days have passed without firmware, the lock may return. Check status via the command fastboot oem device-info - Device unlocked: true must confirm unlocking.

In addition to unlocking, prepare:

  • ๐Ÿ”Œ Original. USB-cable (preferably from the kit) โ€“ cheap cables may not provide stable connection in mode EDL.
  • ๐Ÿ’ป Computer on Windows 7/10/11 (64-bit) with Windows Defender disabled and antivirus (they can block drivers).
  • ๐Ÿ“ฅ Firmware for your model - download only from official sources (see section below).
  • ๐Ÿ”‹ Battery charge of at least 60% โ€“ a sudden power outage during firmware can turn a phone into a brick".

Selection of firmware: official MIUI or custom?

The choice of firmware depends not only on the functionality, but also on the stability of the device. For the Redmi Note 7, two main types of firmware are available:

Type of firmwareAdvantagesDeficienciesWhere to download
Official MIUI (Fastboot)โž• Full compatibility with iron โž• Support OTA-update โž• Minimum risk of bugsโž– Closed source code โž– Advertising in system applications โž– Limited Customization OpportunitiesOfficial MIUI website
Castomic (AOSP)โž• No advertising and no bloatware โž• More recent versions of Android โž• Advanced settingsโž– Possible bugs with camera/sensors โž– No. OTA-update โž– Requires an unlocked bootloaderXDA Developers
Port from other devicesโž• Unique features (e.g, MIUI from Redmi K20)โž– High risk of non-functioning modules โž– No guarantee of stabilityThematic Forums (e.g. 4PDA)

For beginners, we recommend starting with the official firmware in.tgz (Fastboot) format.

  • ๐ŸŒ Global โ€“ for international devices (Google Services support).
  • ๐Ÿ‡จ๐Ÿ‡ณ China โ€“ without Google services, but with additional features for China.
  • ๐Ÿ‡ช๐Ÿ‡บ EEA โ€” European version GDPR-compatible settings.

If you downloaded firmware in.zip format, do not unpack it โ€“ MiFlash only works with.tgz archives or folders with.img files.

Step-by-step: Redmi Note 7 firmware via MiFlash

When all the preparations are complete, you can start firmware. Follow the instructions in strict order - skipping steps or changing the sequence can lead to errors.

Step 1: Install drivers and MiFlash

  1. Download and install Qualcomm drivers (required for EDL mode).
  2. Install the MiFlash Tool (the 2020 version is the most stable for the Redmi Note 7).
  3. Unpack the downloaded firmware in a folder without Cyrillic characters (for example, C:\MIUI\lavender_global).

Step 2: Transfer your phone to EDL mode

There are two ways:

  1. Through Fastboot (if the phone turns on): adb reboot edl Or manually: turn off the phone, press Volume up + Volume down and plug into USB.
  2. Testpoint (if the phone doesn't respond): How to activate EDL Take the back cover off the phone, take the mediator off the phone, and find a dot on the board that says, EDL or TEST And you can plug them in with tweezers. USB-computer-wire.

The successful transition to EDL will confirm the appearance of the Qualcomm HS-USB QDLoader 9008 in Device Manager.

Step 3. Firmware through MiFlash

  1. Run MiFlash on behalf of the administrator.
  2. Press Select and specify the folder with the unpacked firmware.
  3. At the bottom, select firmware mode: clean all โ€“ complete cleaning (recommended for bug fixing). clean all and lock โ€“ cleaning + lock the bootloader (only if you are sure that you will not be flashing!). save user data โ€“ saving user data (risky, can lead to errors).

Refresh

Flash

โš ๏ธ Warning: If the process is stuck on waiting for a device, turn off the phone, restart MiFlash and repeat the steps. USB-cable.

๐Ÿ’ก

Use clean all mode when switching to another version of MIUI (e.g. 12 to 13) to prevent system file conflicts.

Common mistakes and their solutions

Even with the correct instructions, users encounter errors, and here are the most common ones and how to fix them:

Mistake.Reason.Decision
Couldn't find deviceDrivers are not installed or the phone is not in EDL mode.Check Device Manager for QDLoader 9008. Reinstall the driver manually (specify the path to the folder with Qualcomm drivers).
Flash is not doneDamaged firmware files or version mismatches.Download the firmware again (check the MD5 checksum). Try a different version of MiFlash (e.g., 2018).
Anti-rollback errorTrying to install an older version of MIUI than the current one.Check the current firmware version in Settings โ†’ About Phone. Download the firmware with the build number above.
The phone does not turn on after the firmwareIncompatible firmware or interrupted process.Repeat the firmware with clean all mode. If it doesn't work, run through Fastboot using the miflash_unlock.

If you encounter an error not mentioned in the table, check the MiFlash logs (file) flash_log.txt Often, it contains a specific error code that you can Google on the forums. XDA or 4PDA.

๐Ÿ’ก

If the phone is stuck on the Mi logo after firmware, wait 10-15 minutes โ€“ the first download after a clean installation can take a lot of time.

What to do after a successful firmware

When the firmware process is complete and the phone has successfully booted, do a few important things:

  • โš™๏ธ Setup: Go through the initial setup (select language, connect to Wi-Fi). Log in to your Mi Account to restore backups (if any). Disable unnecessary system applications via Settings โ†’ Annexes.

Verification of updates:

Go to Settings โ†’ About Phone โ†’ System Update and check for current security patches.

Data recovery:

If you've been backing up Mi Cloud or Google Drive, restore contacts, photos and apps. Titanium Backup is good for root users.

Additional tweaks (for advanced):

List of useful settings after firmware
Activate Developer Mode and enable Windows Animation x0.5 to speed up the interface. Install Magisk to get root permissions (if needed). Turn off battery optimization for frequently used applications (Settings โ†’ Battery โ†’ Battery Optimization).

If the firmware was made to eliminate bugs, watch the phone for 2-3 days.

  • ๐Ÿ”‹ Battery consumption โ€“ inadequate discharge may indicate background processes.
  • ๐Ÿ“ถ Communication โ€“ check Wi-Fi, Bluetooth and mobile network.
  • ๐ŸŽฎ Performance โ€“ run heavy games (such as Genshin Impact) for stability testing.

Alternative ways to install Redmi Note 7

If firmware via MiFlash is not suitable (for example, due to EDL issues), consider alternative methods:

  • ๐Ÿš€ Fastboot firmware: Suitable for installation of official and custom firmware without EDL. Use commands: fastboot flash boot boot.img fastboot flash system system.img fastboot flash recovery recovery.img fastboot reboot The complete list of commands depends on the firmware structure.
  • ๐Ÿ”„ TWRP + Custom ROM: To install custom firmware (for example, LineageOS or Pixel Experience) you will need: TWRP Recovery via Fastboot. backup of the current system (Backup) โ†’ System + Switch a.zip archive with firmware through Install.
  • โ˜๏ธ OTA-Update: If you need to upgrade to a new version MIUI without full flashing, download.zip from the official site and install through Settings โ†’ Updating the system โ†’ Select the update file.
