Users of Xiaomi and Redmi smartphones often face a situation where the device suddenly falls into a specific diagnostic menu known as Main Menu.The screen appears a list of options in English, and the touchscreen stops responding to usual touches or works incorrectly. This condition causes panic, especially if you do not know how to return the gadget to normal operation without losing data.
Main Menu mode on the Xiaomi Redmi Note 9 is a hidden engineering interface designed to test hardware components in a factory or service center, which can be accessed by accident, by pinching certain buttons when you turn on, or due to a software failure, exiting it is usually simple, but requires accurate knowledge of the sequence of actions so as not to activate unnecessary tests or a complete reset.
In this article, we will discuss in detail all possible ways to exit this menu, from standard methods to forced reboot, and will discuss the causes of this situation and preventive measures that will help to avoid a recurrence of the problem in the future.
What is Main Menu and why does it appear?
The Main Menu interface is part of the Android system layer adapted by the MIUI shell. It is not intended for everyday use by the average smartphone owner. The main function of this section is to diagnose the display, sensor, speakers and other modules before selling the device.
The Redmi Note 9's menu is most often hit by accidentally clamping the volume and power key combination while the phone is on, but there are also software reasons, such as system file failures or damage to the recovery partition, which can cause this mode to start automatically.
⚠️ Warning: Main Menu does not mean your phone is broken, it is a routine situation that is solved by software without contacting the service.
Sometimes the cause is a physical button sticking, and if the volume button is damaged or contaminated, it can send a continuous signal to the system, which is perceived as a command to enter diagnostic mode, in which case the software output can be temporary until the mechanical malfunction is corrected.
State exit via the Reboot button
The safest and most correct way to leave Main Menu on the Xiaomi Redmi Note 9 is to use the built-in reboot function. Most menu versions have a button labeled Reboot at the bottom of the screen or at one of the top corners, which is designed to normally terminate the diagnostic mode.
To perform this operation, you will need to use volume buttons to navigate the menu, as the touch screen in this mode is often turned off or operates in a special test mode. Select Reboot by moving the highlight, and confirm the action with the power button.
☑️ The algorithm of the standard exit
Once confirmed, the system initiates a normal reboot, and if there are no software errors, the smartphone will start as normal and you will see the lock screen. It is important not to panic if the process takes a little longer than usual, which is normal for exiting diagnostic modes.
💡
The Reboot button is the only standard way to exit, saving all user data and settings unchanged.
Forced resetting of the device
If the menu is frozen, the Reboot button is not responding or the screen is not updated, you need to use the forced reboot method, which simulates the extraction of the battery, which allows you to reset the state of the power controller and the processor.
The Redmi Note 9 is a combination of pressing and holding the power button for 10 to 15 seconds, and in some cases, you may need to press the power button and the volume button simultaneously, and hold them until the screen goes out and the Mi logo appears.
This is universal for all Android devices, and is file-safe because modern smartphones have protection against data corruption when power is cut off, but it is often not recommended to use this method to avoid putting too much strain on the memory controller.
💡
If the phone doesn’t respond to a long push of buttons, plug it into the original charger for 5-10 minutes, then try again to force the reboot.
Using Recovery Mode to Exit
In situations where standard methods don't work, you can try to go to Recovery mode. This is a deeper level of system recovery. To get there, turn off the device (if it's stuck in Main Menu, use forced reboot and when you turn off, immediately press the combination).
To log into Recovery on Xiaomi, you usually use the power button and volume button. In the menu that opens, select Reboot and then Reboot to System. Navigation is done with volume buttons and selection is done with the power button.
| Action. | Navigation button | Confirmation button |
|---|---|---|
| Up/down movement | Volume +/Loudness - | - |
| Choice of menu item | - | Power (Power) |
| Getting out of the regime | Reboot's pick | Power (Power) |
Recovery allows you to bypass the hanging processes in Main Menu. However, be extremely careful: selecting items like Wipe Data will lead to the complete removal of all data from your phone. Always choose only Reboot options if your goal is simply to exit the menu.
Diagnostics of hardware buttons
A common cause of cyclic hits to Main Menu is a physical button malfunction. If the volume button is stuck inside the case or has oxidized contacts, the phone will perceive this as a login command to the engineering menu each time it is turned on.
You can check this visually and tactilely, and the presses should be clear, with a very palpable click, and if the button fails, or if it fails, or if it doesn't return to its original position, the problem is the hardware, and then the software methods will only have a temporary effect.
⚠️ Warning: Attempts to disassemble the phone to clean the buttons yourself can lead to loss of warranty.If the device is warranty, it is better to contact an authorized service.
For a temporary solution, you can try tapping your finger gently on the button area or pressing them several times quickly to try to "clasp" the mechanism, if this does not help, you will need to replace the button plume or the module as a whole.
Resetting settings as a last resort
If the software failure is deep and the phone is constantly returning to Main Menu after a reboot, a full reset (Wipe Data) may be required.This action will delete all user data, photos and applications, returning the phone to a factory state.
You can reset via the Recovery menu. Select Wipe Data, then confirm the action. Once the process is complete, select Reboot. The phone will reboot as new, and the cyclic login problem should disappear if it was caused by corrupting system files.
Sequence for discharge:
1. Turn off the phone.
2. Clamp Power + Volume Up.
3. Select Wipe Data.
4. Confirm and wait for the end.
5. Select Reboot.Before doing this, if possible, try to copy important data to your computer or to the cloud, although this is almost impossible in Main Menu mode, so regular backups are the best protection against loss of information.
