Mistakes on Xiaomi (including Redmi models, POCO The first is divided into software (software failures, application conflicts) and hardware (memory, contacts, chips), the first is eliminated by rebooting, resetting or flashing, the second requires repair. In this article, we will analyze all the typical errors (from "Application Stopped" to bootloop) and give step-by-step instructions for their elimination, including hidden functions. MIUI and recovery regimes.

Warning: some actions (for example, unlocking the bootloader or firmware through Fastboot) can lead to data loss or cancellation of warranty. If the phone is warranty, first contact the authorized Xiaomi service. For other readers, we have prepared a unique table of methods compatibility with smartphone models so that you do not waste time on useless manipulations.

1. Typical Xiaomi Mistakes and Their Causes

Mistakes on Xiaomi rarely occur “just like that,” usually preceded by specific user actions or hardware failures.

• 📱 "Application Stopped (e.g. com.android.phone or com.miui.home) – Update conflict, corrupted cache files, or version incompatibility MIUI.
• 🔄 Bootloop – a consequence of unsuccessful update, partition damage /system or hardware memory failure.
• ⚠️ "No Command with a recumbent robot – bootloader failure or damage to recovery files).
• 📵 "SIM card not supported – an error IMEI, failure of the communication module or blocking by the operator.
• 🔋 "Battery not charging" - problems with the power controller, connector or firmware Battery Manager.

Models with a particular vulnerability are particularly vulnerable MIUI Global Stable after automatic updates – often new versions contain bugs that do not appear immediately. 2023 com.google.process.gapps errors occurred after the update MIUI 14 on the Redmi Note 10/11. The manufacturer has released patches only through 3 month.

⚠️ Warning: If the error occurred after a phone fell, moisture hit or self-disassembly, do not try to sew the device. First check the hardware (display, plumes, battery".

2. Charging check. Connect the original cable and power supply, wait 10 minutes. A discharged battery can block the power.
3. Extraction SIM and SD-Sometimes errors cause conflicts with memory cards or SIM cards (especially if they are damaged).
4. Cache reset via Recovery.Clutch power + Volume up, select Wipe & Reset from the recovery menu → Wipe Cache.

If the phone is switched on but is not working properly:

• 📲 Check the space in the memory (Settings) → Storage? Less than 1GB - delete unnecessary files.
• 🔄 Update problematic apps via Google Play or reinstall them.
• 🛡️ Turn off battery optimization for system applications (Settings) → Battery → Optimizing the battery).

If the error persists, go to specialized methods (see the following sections). To clarify the diagnosis, you can use the hidden test menu:

Enter the dialer in ##4636##


Select Phone Information → check the status of the network, battery and sensors.

3. Application error correction (com.android.phone, etc.)

Errors like com.android.phone, com.miui.home, or com.google.process.gapps are related to system services.

• 🗃️ A damaged app cache.
• 🔄 Conflict after update MIUI or Google Services.
• 📱 Incompatibility with custom firmware or root rights.

Solutions:
