Mistake on Xiaomi: how to diagnose and fix the problem yourself

Xiaomi smartphones, tablets and smart devices are known for their value for money, but even they are not immune to crashes. Errors can manifest themselves in various ways, from sudden reboots to complete system failure. Most often, users encounter error codes (for example, E:Foot is wrong in recovery mode), freezes on the Mi logo, or messages like “App has stopped.”

In this article, we will look at the most common Xiaomi errors, their possible sources and specific steps to solve – from simple reboots to flashing through Fastboot. Particular attention will be paid to devices based on MIUI (including Redmi, POCO and Black Shark), as well as typical problems after updates. If your gadget stopped working correctly, do not panic: in 80% of cases, the problem can be fixed without going to the service center.

Xiaomi’s Common Mistakes and Their Codes

Errors on Xiaomi devices fall into two large groups: software (related to software, applications or firmware) and hardware (iron damage), the former most often accompanied by code or a message on the screen, the latter by physical symptoms (overheating, lack of charging, artifacts on the display).

If one of these codes appears on your Xiaomi screen, don’t rush to carry the device for repair. In most cases, the problem can be solved by yourself, following the instructions from the following sections.

The “App Stopped” Error – How to Fix

The message “App has stopped” (or “Unfortunately, [app name] has stopped”) is one of the most common software errors on Xiaomi, which arises from cache conflicts, corrupted app data, or incompatibility with the MIUI version. System services (com.android.phone, com.miui.home) or popular apps (WhatsApp, Instagram) are most commonly affected.

Here is a step-by-step algorithm to eliminate:

• 🔄 Restart the device. Sometimes the error disappears after a simple reboot.
• 🧹 Clear the app cache: Go to Settings → Annexes → Application management. Select a problem application → Warehouse → Clear cache. If the error repeats, click Clear data (Warning: this will delete all application settings!).

Update the app

Google Play

Reset the application settings

Settings → About the phone → Resetting settings → Resetting app settings

If the error appears after the MIUI update, try retracing to the previous version via Recovery.

Download the stable version of MIUI for your model from Xiaomifirmwareupdater.com

Rename the file to update.zip and place it in the root of the memory.

Press Power + Volume Up to log in to Recovery

Select Install update.zip and confirm the installation

After restarting, reset the settings (Wipe data)

A critical com.android.phone error (related to the mobile network) often occurs after a failed modem update, in which case only a complete flashing through Fastboot with a Clean all and lock checkmark will help.

Xiaomi does not include: black screen or stuck on the logo

If your Xiaomi doesn’t respond to the power button, hovers on the Mi/Redmi logo, or shows a black screen, the reasons may be:

• 🔋 Battery discharged (even if the indicator was on fire when charging is connected).
• 🤖 Firmware failure after a failed update or rooting.
• 💥 Hardware failure (damage to motherboard, display plume).
• 🔌 Problems with the charging port (oxidation, mechanical damage).

Diagnostic and Recovery Actions:

1. Check charging: Connect the original cable and power supply. Leave at least 30 minutes on charging - sometimes the device shows no signs of life due to deep discharge. Try another charger (preferably with Quick Charge support).
2. Perform Forced Reboot: Press Power + Volume Up for 15-20 seconds. If the Recovery menu appears, select Reboot.
3. Enter Fastboot mode: Press Power + Volume Down before the hare appears in the eardress cap. Connect the device to your PC and check if it is determined by the command: fastboot devices

Refuse the device.

• Download the firmware for your model from the official website.
• Use the Mi Flash Tool (for Windows) or fastboot commands to install.
• ❌ Error 67 (network registration): Check if your account supports SIM-VoLTE card (settings) → SIM-map → Enable VoLTE. Update the modem firmware via Fastboot (PC required). If the error occurred after the update MIUI, Reset network settings: Settings → System system → Resetting settings → Resetting network settings

If the network has not recovered after all the manipulations, check the device's IMEI (type *#06#). If the number shows zeros or "Invalid", this indicates damage to the modem part of the firmware, in which case only flashing through the Fastboot with the Clean all tick will help.

💡

If the mobile network goes missing after the reboot, try disabling the dual app feature (Settings → Apps → Dual apps).Some Redmi Note 10 Pro users reported that this solved the problem.

Mistakes after the MIUI update: how to roll back or restore the system

MIUI updates often bring not only new features, but also unforeseen bugs, from minor interface glitches to complete device failure. If after the update your Xiaomi began to slow down, overheat or give out errors, there are several ways to restore stability:

1. Cache clearing via Recovery: Turn off the device. Press Power + Volume Up to log in to Recovery. Select Wipe & Reset → Wipe Cache. Reboot the device. This method helps 60% of the time and doesn't delete user data.
2. Retract to previous version of MIUI: Download stable firmware for your model from xiaomifirmwareupdater.com. Rename the file to update.zip and place it at the root of internal memory. In Recovery, select Install update.zip. After installation, run Wipe data (this will delete all data!).

Fastboot flashing through Fastboot

• Download Mi Flash Tool and firmware in.tgz format.
• Connect the device in Fastboot mode (press Power + Volume Down).
• In the program, select Clean all and start the firmware.

If after updating MIUI 14 on Xiaomi 12/13 series sound was lost in the speaker, check the settings of the Atmos Doll (Settings → Sound → Sound Effects).

Charging errors: Xiaomi does not charge or discharges quickly

Charging problems are one of Xiaomi’s most common hardware problems, and they manifest themselves in different ways:

• 🔌 The device does not charge at all (even when connected to the network).
• ⚡ Charging is very slow (for example, 1% in 30 minutes).
• 🔋 The battery discharges quickly (from 100% to 0% in a few hours).
• 🔥 The phone overheats during charging.

Causes and solutions:

If your Xiaomi is older than 2-3 years and the battery is less than half a day, most likely, you need to replace the battery. For models with a non-removable battery (for example, Redmi Note 11, Xiaomi 12T), this procedure is better entrusted to professionals – self-replacement can damage the plumes.

💡

If the phone is not charging above 1% or shows "Charging suspended" at high temperature, this may indicate a malfunction of the power controller.

When to contact the service: signs of hardware malfunctions

Not all Xiaomi errors can be fixed on their own, but there are a number of symptoms that clearly indicate hardware problems and require the intervention of specialists:

• 💥 Physical injuries: Cracks on the motherboard after falling, traces of oxidation or corrosion (for example, after moisture enters), fallen or bent contacts (visible when disassembling).
• 🔥 Overheating for no apparent reason: The device heats up to 50°C+ Automatic shutdown due to overheating.
• 📵 Display problems: Artifacts (strips, flickering, broken pixels) touches don't work or they work on their own ("phantom taps").
• 🔊 Sound malfunctions: The speaker is wheezing or not working at all.
• 📡 Problems with antennas: No signal GPS even in open areas. Wi-Fi/Bluetooth They don’t catch the network, although everything works on other devices.

⚠️ Note: If your Xiaomi device has been hit by water or has been subjected to severe vibration (for example, after a fall), do not turn it on, even if it is externally whole:

1. Remove the battery immediately (if it is removable).
2. Place the device in a silica gel bag for 24 to 48 hours.
3. Do not try drying with a hair dryer or putting it on the battery – this will aggravate the damage!
4. Contact the diagnostic service.

The cost of repairs in official service centers Xiaomi depends on the model and type of malfunction. For example, replacing the display with the Redmi Note 10 Pro will cost 5-8 thousand rubles, and repairing the motherboard – from 10 thousand rubles and more. If the device is warranty, repair can be free (but not always – the warranty does not cover damage from moisture or mechanical breakdowns).
