Xiaomi Redmi Note 4 is one of the most reliable low-end devices released a few years ago, but over time, even the most stable gadget can face software errors, a severe decline in performance or the accumulation of system debris that cannot be removed by conventional cleaning methods.
Often referred to as hard reset, the reset procedure completely deletes all user data, including contacts, photos, installed apps and account logins. It is critical to back up all valuable information before any manipulations, since it will be impossible to recover files after a reset without a pre-created backup.
There are several ways to perform this operation on a MIUI-enclosed device: through the standard settings menu if the phone is turned on and responding to commands, or through Recovery mode if the system is not booting. The choice of method depends on the current technical condition of your gadget and access to the interface.
Preparation of the device for the discharge procedure
Before you start active memory cleanup, you need to make sure that the battery is at least 50-60% charged. The partition formatting process is energy intensive, and a sudden power outage in the middle of the operation can damage the system files or even completely fail the motherboard. If the charge is low, connect the device to the original charger and wait for the set of capacity.
Be sure to extract SIM-microSD card and memory card before the procedure, although modern versions MIUI The memory card usually does not affect external drives during a standard reset, the risk of accidental formatting or damage to the file system of the memory card still exists.
Owners of devices with an unlocked bootloader or someone who has previously logged into a Mi Account or Google Account need to know their credentials. After the reset, the security system will require you to enter a login and password to confirm ownership, otherwise the phone will remain locked.
☑️ Checklist before reset
💡
Take pictures of screens with important settings or passwords from Wi-Fi before resetting – this will save time to restore the usual network configuration.
Method 1: Reset via MIUI system settings
The safest and easiest method is available to users whose phone is functioning normally and allows you to log in. First, open the Settings app and scroll down to About, which is where the basic system management tools hide.
In the menu that opens, select the option “Reset”; the system will warn you that all data will be deleted; if the device has a lock screen, you will need to enter a pattern lock or a digital code; then click “Erase all data” or “Reset settings”.
Once confirmed, the smartphone will restart and start the cleaning process, the screen can go out and light up, and the progress bar will display the status of the operation, and it is important not to interrupt this process and not press buttons until the device itself is turned on in the initial setting.
Method 2: Hard Rescue via Recovery Mode
If the operating system is not booting, freezes on the logo or the touch screen does not respond, the recovery mode is used. To enter it on the Xiaomi Redmi Note 4, you need to turn off the device completely. Then simultaneously press the volume button and the power button.
Hold both buttons until the Mi logo appears, then release the power button while holding the volume button. In a few seconds, the Recovery menu will open, where the control is carried out by the volume buttons (up/down), and the choice is confirmed by the power button.
In the menu list, select "Wipe Data"; in some versions of Recovery, you may need to select "Wipe All Data" option. Confirm by selecting "Confirm". After cleaning, select "Reboot" to restart the system.
⚠️ Attention: In Recovery mode, the touch screen is not working. All actions are performed strictly mechanical volume and power buttons.
💡
Using Recovery Mode is the only way to regain access to the system if the phone is not turned on or locked.
Removing Forgotten Passwords and Blocks
Often users are looking for ways to reset to unlock the device, forgetting the pattern lock or password. On modern versions of Android and the MIUI shell, a simple reset via Recovery does not always remove the screen lock due to embedded data protection.
If, after resetting and booting, the system requires you to enter a password that you do not remember, it means that FRP (Factory Reset Protection) protection has worked, you can only bypass it by entering a Google or Mi Account that was synced with the phone before locking.
When accounts are completely lost, official service centers can only unlock a device with a purchase receipt and a box of proof of ownership. Third-party methods of circumventing FRP often require complex software and do not guarantee the result.
| Type of lockdown | Method of decision | Data security |
|---|---|---|
| Forgot screen password | Reset via Recovery | Data deleted |
| Blocking Mi Accounts | Entering account password | Internet is required |
| Google Blocking (FRP) | Entering a Google account | Internet is required |
| System failure (Bootloop) | Hard Reset / Firmware | Data deleted |
Common Errors and How to Resolve Them
One common problem is that you're stuck on the Mi logo after a reset, which may indicate damage to the system partition or incompatibility with the installed firmware version, and you may need to flash the device through your computer using the Mi Flash Tool.
Another error is the message “Update failed” or “Can’t verify update” when trying to reset, often because there is too little free memory left in the storage for system operations. If the phone turns on, try removing some of the heavy files or applications manually before resetting.
If the phone is constantly rebooted after reset (cyclic reboot), check the status of the power button. Sometimes it will fuse or become contaminated, which is perceived by the system as a constant retention and a command to restart. Mechanical cleaning or replacing the button plume solves the problem.
What happens if Recovery does not open?
Data recovery after cleaning
Once you have successfully completed the reset and set up the device, you can start restoring information. If you have used Google services or the Mi Cloud, the process will take place automatically when you log in to your account, and contacts, notes and calendar are synced in the background.
Photos and videos can be returned if Google Photos or Mi Gallery has been enabled with sync, and apps can also be downloaded again through the Play Market or GetApps store by going to the Library or My Applications section, where installation history is stored.
Recovery from a memory card, if formatted, will require specialized PC programs such as Recuva or DiskDigger, but success depends on whether memory sectors were overwritten with new data after formatting.
⚠️ Do not install questionable antiviruses or “accelerators” on a newly dropped phone – they often cause new system failures.
