How to get out of Main Menu on Xiaomi Redmi 7A: a step-by-step guide with a security guarantee

Why Smartphones Are Stuck in Engineering Menus and What to Do About It

Owners of Xiaomi Redmi 7A sometimes face a situation where, after accidentally pressing a button combination or unsuccessfully updating the device, the device is loaded not into the usual MIUI interface, but into the so-called Main Menu (engineering menu), a service mode designed for testing hardware components and low-level diagnostics, it looks like a text menu on a black or blue background with items in English such as Reboot, Wipe Data or Advanced.

The main problem is that without knowing special commands or key combinations, it is impossible to exit this mode in the standard ways. Many users in panic try to reboot the phone with the power button, but this only brings them back to Main Menu. Moreover, careless actions in this menu (for example, selecting the Wipe Data item) can lead to complete loss of data without the possibility of recovery, even if you did not plan to reset.

In this article, we will discuss 5 working ways to exit Main Menu on Redmi 7A, including methods without loss of data and with minimal risk to the system. You will also learn how to prevent re-entry into the engineering menu and what to do if none of the methods worked. All instructions are tested on current versions of MIUI 12-14 firmware and adapted to the features of the Qualcomm Snapdragon 439 hardware platform on which the Redmi 7A is built.

Method 1: Standard menu reboot (without data loss)

The easiest and safest method is to use the built-in reboot option in the Main Menu itself.It is suitable if the menu is displayed correctly and you can control the selection of items using volume and power buttons.

Instructions:

• 🔄 Use the Volume Down button to move the output to Reboot or Reboot System Now.
• ✅ Press the power button to confirm the choice.
• ⏳ Wait for the reboot (may take up to 2-3 minutes). If the screen is out and does not turn on for more than 5 minutes, proceed to the next method.

If the Reboot option is missing or inactive, it may mean that the menu is running in emergency mode (for example, after a firmware failure).

1. Select Advanced → Reboot to Bootloader.
2. After switching to Fastboot mode (black screen with the Mi Bunny logo), hold the power button for 10-15 seconds for a forced reboot.

💡

If the volume buttons don't respond, check if they're software-locked, and then plug your phone into charging, which will sometimes unlock the control.

Method 2: Forced reboot with hardware buttons

If the menu doesn't respond to presses or the screen is frozen, you can try to exit Main Menu in a "hard" way, which works even if the touch screen or volume buttons are not functioning.

Follow the following steps:

⚠️ Note: On some firmware, prolonged button retention may result in automatic resetting (e.g., if Safe Mode is activated:

• 🔋 Make sure the battery is over 30%.
• 📴 Turn it off. SIM-card and memory card (if installed).

If the phone hits Main Menu again after the reboot, it indicates damage to the boot sector, in which case you will need to flash it through Fastboot or EDL-The regime (which will be discussed further).

Method 3: Exit via Fastboot (for power users)

If standard methods don’t work, you can try rebooting your device via Fastboot mode, which requires connecting your phone to your computer and using the fastboot utility from the Android SDK package.

Step-by-step:

1. Hold the Power + Volume Down buttons until the screen with the Fastboot logo appears.
2. Get Redmi on board. 7A PC-only USB-cable.
3. Open the command prompt (Windows) or terminal (Linux/macOS) and type:

fastboot devices

If the device is determined (the serial number will appear), follow the reboot command:

fastboot reboot

If the command fails or if it gives an error waiting for the device, check:

• 🔌 Quality. USB-Cable (Try the Original Xiaomi Cable).
• 🖥️ Have Qualcomm drivers been installed? HS-USB QDLoader 9008 (you can download it on the official Xiaomi website).
• 🔄 Reconnect the cable by changing the port USB PC-only.

Method 4: Reset settings via Recovery (extreme case)

If none of the previous methods worked, the option of resetting settings through Recovery Mode is left, which removes all data from the device (photos, contacts, applications), so use it only as a last resort.

How to perform the reset:

1. Turn off the phone (hold the power for 10-15 seconds).
2. Hold the Power + Volume Up combination until the Mi logo appears and you move to Recovery.
3. In the Recovery menu, select: 🌐 Wipe Data → Wipe All Data (complete reset). ✅ Confirm the action (usually you need to select Confirm).

Reboot

Reboot to System

⚠️ Note: On some versions MIUI Recovery menu items may be called differently (e.g. Clear Data instead of Wipe Data).If you're not sure, take a picture of the screen and check the official Xiaomi documentation for Redmi. 7A.

Method 5: Firmware through EDL (to restore the “brick”)

If Redmi 7A After manipulation with Main Menu, it stops turning on or loads only in mode EDL (Black screen, defined by PC as QHSUSB_BULK), It's a complicated and risky method, but it's the only one that can bring the phone back to life in the case of a software brick».

What you need:

• 🖥️ Windows computer 7/10/11 (For the Mi Flash Tool).
• 📁 Official firmware for Redmi 7A (download from Xiaomi website).
• 🔧 Mi Flash Tool (last version).
• 🔌 Original. USB-cable (preferably with data transmission support).

Step-by-step:

1. Unpack the firmware in a folder without Cyrillic characters (for example, C:\redmi7a_firmware).
2. Install Qualcomm drivers (if the PC doesn’t see the device in Device Manager).
3. Open the Mi Flash Tool, press Select and point the path to the firmware folder.
4. Connect Redmi off. 7A To PC, holding Volume Up + Volume Down (the phone must be determined as a phone) COM-port).
5. In the Mi Flash Tool, press Refresh, then Flash. Wait for the process to end (10-15 minutes).

⚠️ Attention: Firmware through EDL erase IMEI, Serial number and eMMC data. Recovery may be required after the procedure IMEI using engineering codes (e.g. #4636##) or utilities SN Writer Tool.

💡

Firmware through EDL is the last chance to bring the Redmi 7A back to life, but it requires strict adherence to instructions, and errors at this stage can lead to irreversible loss of functionality of the communication module or memory.

How to prevent re-entry into Main Menu

To avoid accidentally entering the engineering menu in the future, follow these guidelines:

• 🔐 Turn off the developer mode if you don't use its features. → The phone. → Version. MIUI and tap 7 times on the build number, then go back to Settings → Additionally. → For developers and deactivate the switch.
• 🔧 Do not press volume and power buttons for longer than 5 seconds at the same time – this can trigger Main Menu or Fastboot.
• 📱 Install protection on the boot menu via the Security app (in some firmware) MIUI There is an option “Protection of the download»).
• 🔄 Regularly update the firmware: in new versions MIUI Bugs leading to spontaneous start of engineering menu are eliminated.

If you often work with custom firmware or system modifications, back up your NVRAM (IMEI and serial number partition) using the MTK Droid Tools utility or SP Flash Tool.
