How to reset the factory settings Xiaomi Redmi 9A: full instructions

Budget smartphones such as the Xiaomi Redmi 9A can accumulate software debris over time, leading to slowdowns in MIUI or periodic freezes. Often users are faced with a situation where the device stops responding to touch or forgets the previously installed screen lock protection code.

The return procedure removes all user information, including contacts, photos, installed apps and account settings, a radical but often necessary step to restore the device without going to the service center. It is important to understand that once you complete the process, you will get a clean system similar to the one that was immediately after unpacking a new device in the store.

Before you start to take action, you need to understand the irreversibility of the operation and be prepared carefully. If you just want to speed up the phone, maybe less radical methods of cleaning the cache will help, but for deep system failures or selling the device, a complete reset is the standard. Let's take a look at all the nuances of preparation and the algorithm of actions for your model.

Preparing the device for a complete data reset

The first and most critical step is to save important data, because it will be impossible to restore it after formatting internal memory using standard means: back up your contacts by syncing them with your Google or Mi Account account, and transfer the photos and documents to your computer or cloud storage, ignoring this step will lead to irretrievable loss of personal information, which is especially true for users who have not done backups before.

Be sure to check the battery level, which should be at least 50-60%.The process of formatting and reinstalling system files can take 10 to 30 minutes, and a sudden power outage at this point is fraught with damage to the bootloader or damage to the file system.If the charge is low, plug in the original charger and leave the phone on charge before the procedure begins.

First, open the main application menu and find the Settings icon, which usually looks like a gear.

In the options list that opens, scroll down to About Phone or Advanced Settings, depending on the firmware version.

Next, you may need to confirm via SMS or password from the Mi Account. Once confirmed, the phone will restart and begin the cleaning process, which will take a few minutes.

Method 2: Hard Reset with Recovery Mode

This is a bootloader-level method that doesn't require access to the operating system. To enter this mode on Redmi 9A, turn off the device completely and wait for the vibration to occur.

Press the power and volume buttons at the same time ("Loud Up"). Hold them until the Mi logo appears, then release the power button, but continue to hold the volume button until the Main Menu menu appears. The navigation in this menu is done with volume buttons (up/down), and the choice of item is made by the power button.

Select Wipe Data from the list, then confirm the selection and go to Wipe All Data. You can again warn about the consequences. You can select Confirm and wait for the process to be completed. After a successful reset, you will see the message "Data wiped successfully", and then you will select Back to Main Menu and then Reboot to restart.

Otherwise, the new owner will face an activation screen where your email and password will be required, which can be interpreted as locking the stolen device.

To delete your account, go to Settings β†’ Accounts and Sync β†’ Google. Select your email address and click on Delete Account or Sign Out. Repeat the procedure for all added accounts, including Mi Account, if used.
