How to reset Xiaomi Redmi 9C to factory settings: 3 working ways

Resetting the Xiaomi Redmi 9C to factory settings is a procedure that can solve many problems, from slowing down to fixing bugs after a failed upgrade. But not all users know that a full reset removes all data from the device, including photos, contacts and installed apps. If you did not back up in advance, it will be impossible to restore information.

This guide will explain in detail how to properly reset the Redmi 9C in three ways: through phone settings, Recovery mode, and even if the device is locked. We will also look at what pitfalls can occur and how to avoid them, such as why the phone may not turn on after a reset or why certain features (such as unlocking the bootloader) require additional manipulation.

⚠️ Critical warning: Xiaomi models with Mi Account binding may require login and password entry after reset. If you forget the data, restore it before the procedure begins, otherwise you risk getting a brick".

1.Resetting preparation: what to do in advance

Before you reset Redmi 9C, follow a few steps that will save you from losing important data and unforeseen problems.

First, back up. Use the built-in Mi Cloud (if your account is tied) or copy files to your computer.

• 📸 Photos and videos – can be transferred through the Gallery → Choose. → Exports.
• 📞 Contacts – sync them with Google Account in Settings → Accounts.
• 🔑 Wi-Fi passwords – write them down separately (after resetting the network, you will have to configure again).
• 🎮 Game saves – if the game supports cloud backup (e.g. via Google Play Games).

Second, check the battery power. Make sure the charge level is at least 50%. If the phone runs out during a reset, it can damage system files and require firmware through the Fastboot.

Third, untie your accounts (if you plan to sell your phone). Go to Settings → Accounts → Mi Account and remove the link. This will save the new owner from having to enter your data after the reset.

2. Method 1: Reset via the settings menu (the easiest)

This method is suitable if the phone is turned on and you have access to the menu.Instructions are relevant for the Redmi 9C on MIUI 12/13/14.

Open Settings (the gear icon on the home screen) and follow the following steps:

1. Go to the About Phone section (usually at the bottom of the list).
2. Slip on Reset (may be called Reset and Reset).
3. Select to erase all data (reset to factory).
4. Enter. PIN-code or pattern lock, if requested.
5. Confirm the action by pressing Erase Everything.

The phone will reboot and start the cleaning process. It can take 5 to 15 minutes -- don't interrupt it! -- when you're done, you'll see the screen of the initial setup, just like after you've bought it.

Make sure your phone is at least 50% charged

Backup of important data

⚠️ Warning: If after a reset, the phone requires you to enter the Mi Account password, but you do not remember it, do not try to guess. After 5 unsuccessful attempts, the device will lock for 24 hours.

3. Method 2: Reset via Recovery Mode (if the phone is not turned on)

If the Redmi 9C is stuck on the logo, does not respond to touch or is locked, use Recovery mode, which works even without access to the system.

For entrance to Recovery:

1. Turn off the phone (press the power button for 10 seconds if it freezes).
2. Press the Power button and the Volume up simultaneously.

2. Confirm the action by selecting Wipe All Data.
3. Wait for the process to be completed (Success will appear on the screen).
4. Go back to the main menu and select Reboot to reboot.

⚠️ Note: If the Recovery menu does not include Wipe Data, it means that the phone has custom firmware installed. IMEI Or other errors, you better go to the service center.

Method 3: Reset via Fastboot (for power users)

This method will come in handy if the first two methods didn’t work, or if the phone is in a bootloop state (infinite reboot), it will require a computer with ADB/Fastboot drivers installed and a USB Type-C cable.

Procedure:

1. Download and install Google’s Platform Tools.
2. Turn off Redmi 9C and put it in Fastboot mode: Press the Power + Volume buttons down for 10 seconds.
3. Connect your phone to your PC and open the command prompt (cmd) in the folder with the platform-tools.
4. Enter the command to check the connection: fastboot devices If the phone is determined (serial number will appear), continue.
5. Run reset: fastboot erase userdata fastboot erase cache fastboot reboot

Once the phone is restarted, it will be in factory condition, and this method doesn't remove the firmware, but it erases all user data.

💡

If the fastboot device command doesn’t show your Redmi 9C, install the drivers manually through Device Manager (Other Devices section).

⚠️ Note: If you have disappeared after the discharge IMEI (show Null/Null), Do not attempt to restore it through third-party programs, this may lead to permanent loss of the network.

6.How to recover data after reset (if there was no backup)

If you forgot to back up, the chances of getting your data back depend on whether the memory sectors were overwritten after the reset. The less you used your phone after cleaning, the higher the probability of recovery.

Recovery methods:

• 🔍 Memory scanning software: DiskDigger (for photos and videos) EaseUS MobiSaver (for contacts and messages) ⚠️ It only works if the phone is unlocked and root rights are available.
• 🖥️ Lab call: Specialists can extract data from a memory chip (eMMC), but it is expensive (from 5,000) ₽) It does not guarantee 100% results.
• ☁️ Checking Cloud Services: Sometimes photos are automatically synced to Google Photos or Mi Cloud, even if you didn’t enable this feature.

⚠️ Important: Don't install recovery software on the phone itself, it will overwrite deleted data. Use only the computer!

💡

The only reliable way to save data is to keep a regular backup, so even if your phone is stable, backup once a month.
