Method 2: Hard Reset via Recovery Mode

If the phone doesn’t turn on, freeze or lock during the boot phase, you’ll have to use Recovery Mode. This method is also useful if you forget your pattern lock or password. The Mi A3 has Google’s stock Recovery (due to Android One), so the interface may be different from MIUI Recovery on other Xiaomi smartphones.

Step-by-step:

1. Turn off the phone (press the power + Volume increase for 10 seconds).
2. Press Power + Volume Up and hold for 10-15 seconds until the Android logo appears.
3. In the Recovery menu, use volume buttons for navigation and power to select.
4. Select Wipe data/factory reset → Yes.
5. Once completed, select Reboot system now.

If you don't have Wipe data on the Recovery menu, you have custom Recovery installed (like TWRP).

• 🔧 Choose Wipe. → Advanced Wipe.
• 📋 Check Dalvik, Cache, Data, System (if you need full formatting).
• 🔄 Swipe to Wipe (Swipe to Wipe).

Method 3: Formatting via Fastboot (for power users)

This method is the most radical and is used if:

• 🔄 The phone doesn’t even load in Recovery.
• 🔓 You need to remove the custom firmware or return the stock.
• 🛠️ You need to unlock the bootloader or flash a modified Recovery.

The work will require:

• 💻 Computer with drivers installed ADB/Fastboot (Download from the official Google website).
• 🔌 Original. USB-cable (better from the set).
• 🔓 Unlocked bootloader (if you plan to stitch custom software).

Instructions:

1. Turn off the phone.


2. Squeeze Power + Volume down before the Fastboot screen appears (robot with open stomach).




3. Connect the phone to the PC.




4. Open the command line (Windows) or terminal (macOS/Linux) in the folder with the platform-tools.




5. Enter a command to check the connection:


   fastboot devices


(Serial number of the device must be displayed).




6. For full formatting (remove ALL, including firmware!) do:


   fastboot erase userdata
   fastboot erase cache
   fastboot erase system


7.Reset the phone:


   fastboot reboot

⚠️ Warning: The fastboot erase system or fastboot flash system will destroy the operating system. Once executed, the phone will not boot without the firmware of the stockware via the Mi Flash Tool!

💡

If the phone does not respond after the commands in Fastboot, try using fastboot oem unlock (requires prior unlocking of the bootloader through the official Xiaomi website).

5. Features of Xiaomi Mi A3 formatting: what you need to know

The Mi A3 has several unique nuances that are important to consider when resetting:

Another critical feature of the Mi A3 is that there is no memory card slot, which means that all the data is stored in internal memory, and the loss of it when formatted is irreversible without a backup, and this model does not work on OTG in Recovery, so you can not restore the firmware from the flash drive.

💡

On the Xiaomi Mi A3, you can’t use fastboot format commands for boot or recovery partitions without first unlocking the bootloader.

6.Recovery after formatting: the first steps

After a successful reset, the phone will return to factory status.

1. Language and region setting: Select Russian (Russia) or another language you want.
2. Wi-Fi Connection: Use the same network as before the reset (the password can be viewed on the router sticker).
3. Sign in to Google Account: Enter the same account that was linked before the reset (otherwise, FRP may work).
4. Data recovery: ☁️ From Google Drive (Contacts, Calendar). 📱 From local backup (if saved on PC). 🎵 Music and photography – through USB-cable.

If your phone is running slower than before, check:

• 🔄 System Updates: Settings → System system → Update of the PO.
• 🧹 Background Processes: Disable Autoboot of Unnecessary Applications in Settings → Annexes → Auto-start.
• 🔋 Energy Saving: Activate Adaptive Battery Mode in Power Settings.
