How to reset your settings on Xiaomi Redmi 9C: a complete guide with photos and nuances

Why do you need to reset your settings to Redmi 9C?

Hard reset on the Xiaomi Redmi 9C is a radical but sometimes necessary solution to get your smartphone back to “clean” status, most often when the phone crashes, whether the interface hangs, apps shut down spontaneously, or the battery drains in a matter of hours, and 80% of these problems are solved by reset, because they involve cache accumulation, software conflicts, or viruses.

Another common reason is to prepare the phone for sale, and even if you delete all files manually, personal data (logins, passwords, message history) can remain in the system folders, and a factory reset is guaranteed to clear internal memory, including hidden partitions where app backups are stored, which is especially important if you've used features like Mi Cloud or Google Autocomplete.

Less obvious cases where a discharge is required:

• 🔒 Forgot the pattern lock or PIN-code - without reset, you will not be able to unlock the phone (if you do not have a Mi Account tied).
• 🐢 System updates were made with errors after a failed update MIUI The phone can be rebooted cyclically.
• 📱 Conflict after manually removing system applications – for example, if you deleted com.miui.securitycenter via ADB.
• 🚀 Customization Preparation – A clean system is required before installing custom firmware (e.g. Pixel Experience.

But resetting is not a panacea; if problems are caused by physical damage (such as a bloated battery or an oxidized motherboard), it won't help; it's also useless to reset when hardware is constrained, such as if the phone is overheated by a thermal paste.

Preparation for resetting: what to do in advance

Before you start resetting, make sure you don’t lose important data. On Redmi 9C, reset removes ALL from internal memory, including photos in the DCIM folder, downloads, and even files hidden from the user (such as system application logs).

Here is the checklist of mandatory actions:

Pay special attention to Xiaomi account (Mi Account), if you forget the login details, after reset, the phone may require you to enter them for unlocking (Mi Cloud Activation Lock function), which is protection against theft, but it can also lock your own phone, to avoid problems:

• 📌 Make sure you remember the email and password from your Mi Account.
• 📌 Check if your account is linked to your phone: go to Settings → Xiaomi account.
• 📌 If your account is not yours (for example, the phone was bought with your hands), be sure to delete it before reset via Settings. → Account. → Delete the account.

If you are planning to sell your phone, don’t be lazy to log out of all accounts in advance:

• 📱 Google: Settings → Accounts. → Google → Delete the account.
• 📱 Mi Account: As stated above.
• 📱 Social Media: Application settings → Exit/Delete data.

⚠️ Note: If you don’t delete your Mi Account before resetting, the new owner won’t be able to use the phone without your login details.

Method 1: Reset via the settings menu (soft reset)

This is the easiest and safest method if the phone turns on and you remember the unlock password, which is suitable for most users, as it does not require additional tools.

Step-by-step:

1. Open Settings (the gear icon on the main screen).
2. Scroll down and select About Phone.
3. Click on Backup and Reset (in some versions of MIUI, this item may be called Settings Reset).
4. Select Resetting → Delete all data.
5. If requested PIN-code or pattern lock, enter it.
6. Confirm the action by clicking Reset Settings (usually the red button).

The phone will reboot and start the cleaning process, which will take 3-10 minutes, and when you complete it, you will see the screen of the initial setup, as after you purchase it.

⚠️ Note: If after resetting the phone requires you to enter Mi Account data that you did not delete in advance, do not try to find the password repeatedly. After 5 unsuccessful attempts, the device will lock for 24 hours. In this case, only an official appeal in support of Xiaomi with proof of purchase will help.

💡

If the phone slows down and does not allow you to open the settings, try to run them through the search: swipe down the main screen and enter “reset”.

Method 2: Hard Reset with Recovery Mode (if the phone is not turned on)

This method comes in handy if the Redmi 9C does not load beyond the logo, cyclically reboots or is locked with a password. Recovery Mode is a service mode built into the firmware that allows you to control the phone without fully booting the system.

To enter Recovery:

1. Turn off the phone (press the power button for 10 seconds if it freezes).
2. Press and hold the buttons at the same time: Volume up + Power (for Redmi 9C with MIUI 12 and newer). If it doesn't work, try Volume up + Volume down + Power.
