How to bring Xiaomi Redmi 9A back to factory settings: the full guide to 2026

When to Reset Redmi 9A and What It Gives

Resetting the Xiaomi Redmi 9A to factory settings is a radical but sometimes necessary solution. This budget smartphone, released in 2020, may eventually start to “brake” due to accumulated debris in the system, application conflicts or failed MIUI updates. Restoring factory settings helps return the device to “second life”, but it is important to understand that the procedure removes all user data – photos, contacts, messages and installed programs.

The main reasons for discharge are:

• 🐢 The smartphone is strongly slowing down or spontaneously rebooting
• 🔒 Forgot a graphical key or unlock password
• 📱 Preparation for sale or transfer to another user
• 🛠️ Fixing Errors After Failed Update MIUI
• 🦠 Viral infection or suspicious activity in the system

Before starting the procedure, make sure that the phone has enough battery charge (at least 50%). Interrupting the reset due to discharge can lead to a device "brick" - a state where the Redmi 9A stops turning on or loads only before the Xiaomi logo. Also prepare backups of important data: after reset, their recovery will be impossible without prior backup.

Method 1: Reset via MIUI settings (most secure)

If your smartphone is switched on and you remember the unlock password, use the built-in reset function. This method requires no additional tools and is minimally risky. MIUI 12/13/14 on the Redmi 9A:

1. Open the Settings app (the gear icon on the home screen).
2. Go to the About Phone section. → Backup and reset.
3. Select Resetting → Delete all data.
4. Enter. PIN-Mi Account Code or Password if requested.
5. Confirm the action by clicking Reset the phone.

It takes 5-10 minutes. Upon completion, the device will automatically restart and prompt you to configure MIUI as after purchase. Importantly, if the phone has a Mi Account attached, you will need to enter its unlock details after reset (FRP protection).

Backup your contacts (via Settings → Google → Backup)

Save photos to your computer or cloud

Remember the username/password from Mi Account

Charge your phone to at least 50%

Delete the memory card (if you do not need to format)

⚠️ Attention: If on Redmi 9A root access or custom firmware installed, resetting through settings can lead to a download cycle. In this case, use the method through Recovery (method 2).

Method 2: Hard Resetting with Recovery Mode

If the smartphone does not turn on, hangs on the Xiaomi logo or you forgot the password, resetting through Recovery mode will help. This method works even on a locked device, but requires care: improper actions can damage system files.

Step-by-step:

1. Turn off Redmi 9A with a long press on the power button (10-15 seconds).
2. Press the Power button + Volume up simultaneously and hold for 10-15 seconds until the Mi logo and Recovery menu appear.
3. Select a language (e.g. English) from the menu, then go to Wipe Data → Wipe All Data.
4. Confirm the action by selecting Confirm (some versions of MIUI may require you to enter a password from Mi Account).
5. Once you have finished, select Reboot → Reboot to System.

If the Recovery menu is in Chinese, focus on the location of the items:

• 📛 The first point is the choice of language
• 🧹 Third point: data reset ()
• ⚠️ Fourth point - confirmation of discharge
• 🔄 The last point is a reset.

Method 3: Fastboot Reset (for power users)

If the first two methods fail (for example, due to damaged firmware or the absence of the Recovery menu), the option of resetting through Fastboot mode remains. This method requires a computer with Xiaomi drivers installed and the Mi Flash Tool utility.

What you need:

• 💻 Windows computer 7/10/11 (64-bit)
