Xiaomi phone is constantly rebooting and does not turn on: what to do in 2026

Xiaomi smartphone suddenly turned into a “brick”: the screen flashes the logo MI, It goes into an endless reboot, and sometimes it doesn't respond to the power button at all. Is it familiar? Cyclical bootloop is one of the most common hardware problems on Redmi phones, POCO And Mi lines, but 90 percent of the time, you can fix it yourself, and the causes range from firmware failure to physical damage to the board, and the solutions range from basic reset to soldering of components.

In this article, we'll look at all possible scenarios, from software to hardware, with step-by-step instructions, risk warnings, and a method compatibility table for different models.°C when you try to turn on, immediately go to the section about hardware malfunctions - here it is already impossible to do without repairs.

1. Causes of Xiaomi's cyclical reboot

Infinite rebukes rarely occur "just like that." 75 percent of the time, system files are corrupted, but there are other triggers:

🔹 Programmatic failures:

• 📱 Failed update MIUI — interrupted firmware or “raw” version of the software (especially relevant for beta versions).
• 🗑️ Application Conflict – Viruses Modified APK system utilities (for example, Magisk after an incorrect root).
• 🔄 Reset to factory settings via Recovery, made with errors.

🔹 Hardware problems:

• 🔋 Faulty battery – bloating, short circuiting, or failure of the power controller (often after a fall).
• 🔌 Damaged charging connector – contact oxidation or chain break.
• 💻 CPU/memory failure – overheating, chip dumping or eMMC defect (found in Redmi Note) 8/9).

Critical information: If the phone reboots after falling into the water or a heavy impact, DO NOT TRY to turn it on - this can lead to a short circuit and a complete failure of the motherboard.

🔹 Other factors:

• ⚡ Unstable charging voltage (use of non-original adapters).
• 🛠️ Failed acceleration/undervoltage through the engineering menu (MTK Engineering Mode).

2.The first steps: what to do before the discharge

Before you start taking any drastic measures, do the basics that will help you 30 percent of the time and save you time.

✅ Check the charging and battery:

• 🔌 Connect the phone to the original charger (not the original charger) USB-Let's stand for 15-20 minutes - sometimes a discharged battery does not allow you to start.
• 🔋 If the charging indicator is not on, try another cable or charge from the power bank.

✅ Forced reset:

• 🔄 Press the power button. + Volume up by 10 to 15 seconds for some models (POCO F3, Mi 11) combination - Nutrition + Turning down the volume.
• ⚠️ If the phone vibrates but does not turn off, the battery can be in deep discharge mode (requires charging 1-2 hours).

✅ Physical injury check:

• 👁️ Inspect the body for the presence of battery bloating (raised cover, slots).
• 💧 If the phone was in contact with liquid, do not turn it on - immediately carry it to the service.

3. Log in Recovery Mode and reset settings

If the phone has any response to the buttons but doesn't load beyond the logo, try hard resetting via Recovery, which will delete all the data, but will return the workflow in 50% of cases.

📌 How to log in to Recovery:

1. Turn off the phone (if it doesn’t respond, press the power supply). + Volume up 20 seconds).
2. Press Power + Volume up until the Mi logo appears, then let go.
3. In the Recovery menu, select the language (volume buttons) and tap Wipe Data.
4. Confirm the reset by using Wipe All Data → Confirm.
5. After completion, press Reboot.

⚠️

⚠️ Note: On some models (Redmi Note 10 Pro, POCO X3) Recovery resets can block the bootloader, and if the phone requires you to enter the Mi Account password after the procedure, and you don't remember it, you'll need to unlock it through the phone. EDL (see section 5).

🔧 If Recovery doesn't open:

• 🔌 Try connecting your phone to your PC and use it. ADB (instruction).
• 🛠️ On older models (Redmi) 4X, Mi A1) You may need to re-flash through Fastboot.

💡

If the phone goes back into reboot after reset, the cause may be a damaged firmware, in which case only firmware (section 5) will help.

4. Diagnosis through ADB and Fastboot

If the phone is detected by the computer but does not turn on, use the tools ADB It's a more advanced method that requires drivers and Mi Flash Tool.

🖥️ Preparation of the PC:

1. Download and install the Mi Flash Tool (the official tool from Xiaomi).
2. Install the drivers. ADB Fastboot (for example, via Android) SDK Platform-Tools).
3. Connect your phone to your PC in Fastboot mode (clip Power + Volume down).

🔍 Diagnostic teams:

fastboot devices # Check the connection of the device


fastboot getvar all # Getting device information




fastboot reboot-edl # Translation to EDL mode (for firmware)

📊 Decoding errors:

💡

If the fastboot reboot-edl command is not working and the phone is not identified in the Mi Flash Tool, the problem may be a damaged bootloader, in which case only soldering or replacing the board will help.

5. Flashing through EDL (emergency)

If the reset and Fastboot did not help, the firmware remains in mode. EDL (Emergency Download Mode – This method works even on dead phones, but requires an authorized Xiaomi account and a special cable (or soldering contacts).

🔧 Step-by-step instruction:

1. Download the full firmware for your model (.tgz format) from xiaomifirmwareupdater.com.
2. Unpack the archive and launch the Mi Flash Tool.
3. Put the phone in mode. EDL: 🔌 For most models: Press the Volume up + Loud down and plug in. USB-cable. 🛠️ For the Redmi Note 8/9: you will need to close the test points on the board (instructions for each model are different!).

Mi Flash Tool

Flash

Wait for the end (10-15 minutes) and the phone will reboot automatically.

⚠️

⚠️ Attention: Firmware through EDL drop off IMEI and serial number on some models (POCO F1, Mi 8: Recovery may be required after the procedure IMEI via the engineering menu (#4636##).

📌 Where to find testpoints for EDL:

• 🔍 For the Redmi Note 7/8/9: Look for contacts near the charging connector (usually signed) EDL or TEST).
• 📱 For POCO X3/F3: Disassembly and closure of contacts on the motherboard is required.

6. Hardware malfunctions: when soldering is needed

If all software methods have been tried and the phone still doesn't turn on, the problem is guaranteed to be hardware.

🔋 Battery:

• 🔌 The phone does not respond to charging, but when connected to a PC is defined as Qualcomm. HS-USB QDLoader 9008.
• 🌡️ The body is swollen or smells of burning.
• 🔄 Forced reboot leads to instant shutdown.

Solution: Replacement of the battery (cost - from 1,500) ₽ service).

💻 Maternity pay:

• 🔥 The phone gets hot when you try to turn on.
• 🛠️ Artifacts appear on the screen (stripes, flickering).
• 🔌 Fastboot is defined as an unknown device.

Decision:

• 🔧 Supplier of the power controller (from 3 000) ₽).
• 🖥️ Replacement eMMC/UFS-accumulator 5 000 ₽).
• 🔄 Full replacement of motherboard (from 8000) ₽).

📶 Antenna module/connectors:

• 📵 Phone is turned on but does not catch the network or Wi-Fi.
• 🔌 Charging is only in one position of the cable.

Solution: Cleaning/replacement of connectors (from 1 000) ₽).

💡

If the phone only turns on when the charger is connected, but turns off when disconnected, it is the power controller or battery that is to blame.

7.Prevention: How to Avoid Bootloop in the Future

To Xiaomi phone does not go into eternal reboot, follow the simple rules:

🛡️ Updates and firmware:

• 📱 Install updates only through official software (Settings) → The phone. → Updating the system).
• 🚫 Avoid custom firmware (such as LineageOS) if you are not sure of its stability.
• 🔄 Before updating, check the reviews on the forums (4PDA, XDA Developers).

⚡ Charging and battery:

• 🔌 Use original chargers (especially for Quick Charge models).
• 🔋 Do not allow a deep discharge (below 10%).
• 🌡️ Do not leave your phone on charge for longer than 2-3 hours after 100%.

🛠️ Physical security:

• 💧 Avoid getting moisture (even condensate).
• 📦 When falling, immediately check the operation of the vibromotor and speakers - their failures can signal damage to the board.

💡

If you are using custom software (Magisk, TWRP), Do backups regularly through adb backup or OrangeFox Recovery, which will save your data when you crash.
