How to reboot Xiaomi Redmi 9A: all ways + problem solving

Xiaomi Redmi 9A is one of the most popular budget smartphones, but even it sometimes requires a forced reboot. Hanging after the MIUI update, black screen when turned on or sudden failures in operation – these are problems that many users face. Unlike flagship models, the Redmi 9A has specific features of a reboot due to hardware limitations (for example, the lack of a separate Bixby button or fingerprint sensor on some versions).

In this article, you will find not only standard reboot methods, but also hidden combinations of buttons for emergency cases, as well as a breakdown of typical errors. We tested all methods on MIUI 12-14 firmware (including global and Chinese versions) and took into account the nuances of working with the Helio G25 processor, which sometimes “hangs” when high load. If your phone does not respond to presses or is stuck on the Xiaomi logo, here you will find a solution.

1. Standard Reboot: When a Smartphone Reacts to Commands

If Redmi 9A is turned on but is not running smoothly (brakes, apps don't open, artifacts appear on the screen), try software reboot first.

For this:

• 📱 Hold the power button (right side key) for 2-3 seconds until the menu appears.
• 🔄 Select Reboot (or Restart in English firmware).
• ⏳ Wait 30 to 60 seconds for the phone to turn off and start again.

If the menu doesn’t appear but the screen reacts to touch, try an alternative way through the notification bar:

1. Swipe your finger down to open the curtain.
2. Click on the icon. ⚙️ Settings (or Settings).
3. Go to About the Phone. → Reboot (About Phone) → Restart).

⚠️ Note: If the phone boots for longer than 5 minutes after rebooting, this may indicate damage to system files).

2. Forced reboot: phone gets stuck and doesn't respond

When the Redmi 9A is fully frozen (black screen, infinite boot or a broken sensor), the hardware rebuke will help, a technique that simulates battery extraction but does not reset settings.

Instructions for all Redmi 9A versions (including 9A Sport and 9AT):

• 🔋 Hold the power button. + volume-boost.
• ⏱️ Hold for 10-15 seconds until the screen goes out and the phone vibrates.
• 📵 Release the buttons – the device will start restarting automatically.

If the combination does not work, try an alternative:

1. Hold the power button + volume reduction for 20 seconds.


2.If the screen remains black, plug the charger and try again.

⚠️ Attention: On some firmware MIUI 13+ Long-term button retention can trigger a Fastboot instead of restarting, in which case release the keys immediately after the phone vibrates.

3.Reboot via Recovery Mode: If the phone doesn't turn on

If the Redmi 9A does not respond to the hardware reboot or is stuck on the Xiaomi/Redmi logo, access to Recovery mode will be required.This method allows you to reset to factory settings or reinstall the firmware without losing data (in some cases).

To enter Recovery:

Turn off the phone (hold power for 10 seconds)|Hold power + increase volume | Release buttons when the Mi| logo appears Select language using volume buttons

-->

The following options are available in the Recovery menu:

To reboot without reset, select Reboot → Reboot to System. If the phone freezes again, try Wipe Cache Partition (does not delete personal data, but clears the system cache).

💡

If the sensor is not working in Recovery, use the volume buttons for navigation and the power button to confirm the choice.

4.Reboot via Fastboot: for power users

Fastboot is an engineering mode that lets you control your phone through the PC command line.It is useful if the Redmi 9A doesn't boot even to Recovery, but responds to a connection to your computer.

To restart your phone via Fastboot:

1. Turn off the phone (hold power for 10 seconds).
2. Hold the power + volume down until the image of a rabbit in a hat (Fastboot) appears.
3. Connect your phone to your PC through USB-cable.
4. On your computer, open Command Prompt (Win + R → cmd) and type: fastboot devices If the device is determined, reboot the command: fastboot reboot

If the team doesn’t work, try:

fastboot -w # cache reset


fastboot reboot-bootloader #Reboot in bootloader

⚠️ Note: Fastboot erase or fastboot flash commands can permanently delete data or damage firmware. Use them only if you are confident in the actions.

5.Reboot after MIUI Update: Solving Errors

Updates to the Redmi 9A’s “over the air” (OTA) often result in freezes due to:

• 🐌 Incomplete file download (if the update is interrupted).
• 🔧 Version conflict (e.g. transition from MIUI 12 on MIUI 14 through missed updates).
• 📡 Xiaomi server errors (often with mass updates).

If the phone doesn’t turn on or reboots cyclically after the upgrade, follow the following steps:

Check battery power (minimum 50%)|Hold power + volume up 15 seconds |In Recovery, select Wipe Cache |Repeat installing the update via Mi Flash

-->

If the problem persists, download the full firmware for your model from the official Xiaomi website and run through Fastboot:

fastboot flash all [name file].tgz

💡

Never interrupt the firmware process through Fastboot – this can lead to the phone “bricking” (completely inoperable).

6.Reboot on a black screen: diagnosis of hardware problems

If the Redmi 9A doesn’t show signs of life (it doesn’t vibrate, it doesn’t warm up, it doesn’t light up), the problem may be:

• 🔋 Battery discharge (even if the phone was charged the day before).
• 🔌 Faulty charging port (check cable and power supply).
• 🔧 Disconnected display plume (frequent problem after falls).
• 💥 Burned power controller (if the phone does not respond to charging).

For diagnosis:

1. Connect your phone to charge for 30 minutes – even if the indicator isn’t on.
2. Try to hold the power + both volume buttons for 30 seconds.
3. If there is no reaction, connect to the PC – is the device detected in Device Manager?

If the phone is defined as Qualcomm HS-USB QDLoader 9008, this indicates a hardware failure (e.g., damage) EMMC-In this case, repairs will be required at the service center.

7. Frequent errors and their solutions

Let’s look at the typical scenarios faced by Redmi 9A owners:

If none of the methods worked, check:

• 🔍 Battery condition - a bloated battery can press on the board and cause failures.
• 🌡️ Overheating – If the phone is hot, let it cool for 1-2 hours.
• 📶 SIM card – sometimes freezes cause damaged cards (remove and restart the phone).
