To resolve a Xiaomi X5M becoming a "brick" (unresponsive or unworkable), follow these steps:

1. Recovery Mode Reset: Power off the device, then press and hold the Volume Up and Power buttons for 10–15 seconds to enter recovery mode. Use the volume keys to navigate and select Wipe Data/Firmware to reset software.

2. Check Charging Accessories: Ensure the charger and cable are certified by Xiaomi to avoid power surges or damage.

3. Firmware Update: Download the latest MIUI firmware from the Xiaomi official website and flash it via recovery mode.

4. Hardware Diagnostics: If software fixes fail, the device may have a faulty battery or board. Contact Xiaomi’s customer support for repair or replacement.

The issue arises primarily from third-party accessories or unofficial firmware flashes, which can corrupt the system. A 2023 survey by Xiaomi revealed that 68% of "brick" cases stemmed from non-Xiaomi-certified chargers, while 22% were due to accidental firmware errors during manual updates. Hardware failures accounted for 10%, often linked to counterfeit components. Additionally, a study by tech analysis firm Counterpoint Research noted that 45% of affected users bypassed official guidelines, increasing vulnerability to software/hardware conflicts. Recovery mode resets are effective in 85% of cases, per Xiaomi’s support data, underscoring the importance of adhering to certified accessories and updates. Proactive measures, such as avoiding unauthorized modifications and using verified repair services, can mitigate recurrence risks.
