How to Get Out of Infinite Bootloop on Xiaomi Redmi 9: 5 Working Methods

Xiaomi Redmi 9 is one of the most popular budget smartphones, but even it is not immune to system failures. If your device is getting stuck on the Mi logo, constantly rebooting or unable to complete the Android bootloop, you are in a bootloop. This problem can occur after a failed update, firmware experiments, resets, or even for no apparent reason.

In this article, we will look at all the current ways to get out of the bootloops on Redmi 9 (including Redmi 9A/9C/9T models), from the simplest to the most radical. You will learn how to diagnose the cause of a failure, what tools you will need, and how to avoid repeated failure. Importantly, the methods are different in complexity - start with the safest and move on to the next ones if the previous one did not work.

1.The reasons behind the bootloop on Xiaomi Redmi 9: why did it happen?

Bootloop rarely occurs out of the blue, and 90 percent of the time it's caused by:

• 🔄 Interrupted software update – if the firmware has not downloaded completely or the phone turned off during installation.
• 🛠️ Incorrect root or system modification - deletion of system files, installation of custom recavery (TWRP) kernel.
• 📱 Hardware malfunctions – damage to the power connector, battery wear or memory problems (eMMC).
• ⚡ Resetting settings via unstable Recovery – especially if you installed Magisk patches before.
• 🦠 Viruses or conflicting applications are rare, but some programs can damage the boot partition.

On Redmi 9, the most common bootloop occurs when you try to upgrade to MIUI 14 on unofficial firmware or when you use utilities like XiaomiTool without unlocking the bootloader. If the phone doesn't turn on beyond the logo but responds to the power button, the problem is software. If the screen is black and there is no vibration, the motherboard may be damaged.

⚠️ Warning: If the bootloop occurred after a phone drop or moisture hit, don't try to stitch the device! First check the hardware - plug it in to charge and see if the case is warming. Overheating in the CPU area (Snapdragon 662) may indicate a short circuit.

2.Recovery preparation: what will be needed?

Before you start the repair, collect everything you need:

Important: Download firmware strictly for your model! 9 (codename lancelot) only the firmware with a marker will fit lancelot_global or lancelot_ru. Installation of firmware from Redmi 9A (dandelion will lead to a full brik of the device!

Also check:

• 🔌 Signature drivers disabled on PC (if Windows is disabled).
• 📱 The phone is defined in Device Manager as Qualcomm HS-USB QDLoader 9008 (for the EDL) Android Bootloader Interface (for Fastboot).
• 🔒 Is the bootloader unlocked? If not, the Fastboot firmware methods won't work.

Method 1: Hard Recovery Reset (without PC)

If the phone responds to buttons and enters the recovery menu, try resetting. This method does not require a computer and is suitable for cases where the bootloop is caused by an application conflict or an unsuccessful reset through settings.

Instructions:

1. Turn off the phone (press Power + Volume up for 10 seconds).
2. Press Power + Volume up until the Mi logo appears, then let go.
3. From the Recovery menu, select Wipe Data → Wipe All Data (use volume buttons for navigation, power for confirmation).
4. Confirm the action and wait for the completion (5-10 minutes).
5. Reboot your phone with Reboot → Reboot to System.

What if Recovery doesn't open? If you press the buttons, the screen is black, or if the logo appears and the boot is rebooted again, the bootloader is corrupted, and only the firmware through Fastboot or EDL (see below).

⚠️ Warning: Recovery reset deletes all data, including photos and messages! If the phone was enabled Mi Account and tied to Xiaomi account, after reset, you will need to enter a username / password to unlock (FRP).

Method 2: Fastboot firmware (if the bootloader is unlocked)

If the bootloader on your Redmi 9 is already unlocked (you previously enabled OEM Unlock in the developer settings), you can flash the phone through Fastboot.This method saves data if you do not use the fastboot erase userdata command.

Step-by-step:

1. Download Fastboot ROM For your model and unpack the archive into a folder without Cyrillic characters (e.g, C:\Redmi9_Fastboot).
2. Open the Command Prompt in this folder (Shift + right mouse button → Open the PowerShell window here).
3. Connect the phone to the PC, press Volume down + Power before the rabbit appears in the hat-eared (Fastboot mode).
4. Enter the command to check the connection: fastboot devices Must appear serial number of the device.
5. Run the firmware: fastboot flash all Or for selective firmware (saves data): fastboot flash boot.img fastboot flash system.img fastboot flash vendor vendor.img
6. Upon completion, type in fastboot reboot

Mistakes and solutions:

• 🚫 Waiting for Device – Check the cable, ports USB Or install Qualcomm drivers.
• 🔒 Device is locked – bootloader is locked, unlock is required (see Method 5).
• ❌ FAILED (remote: 'Flashing is not allowed' - download the firmware for your regional version (Global/RU/EEA).

💡

If the firmware through fastboot flash all doesn’t help, try clearing the partitions first with the command fastboot erase cache and fastboot erase userdata, and then repeat the firmware.

5. Method 3: Firmware via EDL (Emergency Mode)

If the phone doesn't go into the Fastboot or the bootloader is locked, the last software method is EDL (Emergency Download Mode), which works even on bricks, but requires a special cable or short circuit of contacts on the board.

Important: For Redmi 9 (Snapdragon 662), EDL is activated:

• 🔌 Through Testpoint (closing contacts on the motherboard).
• 📱 With cable. EDL (jumper GND and EDL plug-in USB).
• 🔄 Automatically with 3 crashes in a row (if the phone goes into reboot after the logo).

Instructions:

1. Install the Qualcomm 9008 driver (you can download it on XDA).
2. Connect your phone in EDL mode (see spoiler below).
3. Open the Mi Flash Tool, select the folder with the Fastboot unpacked firmware.
4. Press Refresh – the COMX device should appear.
5. Select Clean All (total erasure) or Clean All and Lock (if you want to lock the bootloader back).
6. Press Flash and wait until it is completed (10-15 minutes).

⚠️ Note: Firmware through Clean All deletes all data without recovery, including IMEI! If the network is lost after the procedure, it will be necessary to restore the system. IMEI through QCN-File or Engineering Menu (#4636##).

Method 4: Unlock the bootloader (if it is locked)

If you try to flash through Fastboot you see a device is locked error, the bootloader is locked. Xiaomi blocks it by default for security, but unlocking is possible through the official Mi Unlock Tool utility.

Conditions for unlocking:

• 📱 The phone must be turned on at least before the Mi logo (to contact Xiaomi servers).
• 🔑 Mi Account must be linked to the device (introduced in the settings before the bootloop).
• ⏳ At least 7 days must pass from the moment of attachment of the account (the rule of Xiaomi for new devices).

Instructions:

1. Download the Mi Unlock Tool and install it on PC.
2. Press Volume Down + Power to enter Fastboot.
3. Connect your phone to your PC and start the Mi Unlock Tool.
4. Sign in with the same Mi Account as you do on your phone.
5. Press Unlock and wait until it is completed (5-10 minutes).
6. After unlocking, run your phone through Fastboot (see Method 2).

If the phone doesn’t turn on even before the logo, unlocking through the Mi Unlock Tool is impossible, in which case only the firmware through the EDL with full erasure (see Method 3), but this voids the warranty and can lead to a loss of IMEI.

💡

Unlocking the bootloader through the Mi Unlock Tool is only possible if the phone has any response to the power button, and on completely dead devices, this method does not work.

7. Method 5: Hardware Repair (if nothing worked)

If all software methods have been tried and the Redmi 9 still doesn't come out of the bootloom, the problem could be hardware.

• 🔋 Faulty battery – if the phone turns off at 20–30% charge or does not hold voltage.
• 🔌 Damaged charging connector – oxidation of contacts or break of the supply chain.
• 🧠 EMMC memory problems – the memory chip “dies” after multiple recordings (typical for budget smartphones).
• 📱 Chip dump - after falling or overheating, the contacts of the processor or memory module depart.

How to diagnose:

• Connect your phone to charging – if the indicator doesn’t light up or flashes red, there’s a power problem.
• Check if the body is warming - overheating indicates a short circuit.
• Listen to sounds – clicks or squeaks when connecting to a PC can talk about problems with the board.

In this case, self-repair is not recommended - contact the service center.

⚠️ Warning: If the phone is warranty, do not open it yourself! Xiaomi service center may refuse repairs under warranty if they find traces of autopsy or unofficial firmware.

8. Bootloop prevention: how to avoid the problem in the future?

To prevent Redmi 9 from getting into the bootloom again, follow these rules:

• 🔄 Update the firmware only through official channels (Settings) → The phone. → Updating the system).
• 🛡️ Do not install custom firmware without unlocking the bootloader - this leads to a brick.
• 🔋 Keep an eye on battery power – don’t let it fall below 10% during updates.
• 📱 Regularly do backups through Settings → Additionally. → Backup.
• 🔒 Do not remove system applications without root rights – this can damage boot partitions.

If you like to experiment with the scalp:

• Use only proven sources (e.g. XDA Developers).
• Before you run the firmware, check the hash sums of files (MD5).
• Have a NANDroid backup (can be done via TWRP) on hand.

💡

The most common reason for a bootloops on Redmi 9 is to try to downgrade the MIUI version without unlocking the bootloader. Always check the firmware compatibility with your model!
