SOP-TECH-XM-001: Diagnostic Protocol for Xiaomi Hardware Verification

1. Document Control & Revision History

Version	Author	Approver	Effective Date	Change Description
1.0	Principal Consultant	CTO Office	2023-10-27	Initial release; baseline diagnostic standards.

2. Executive Summary & Scope

This Standard Operating Procedure (SOP) defines the rigorous protocol for executing USSD (Unstructured Supplementary Service Data) codes and integrated engineering menus on Xiaomi (MIUI/HyperOS) hardware. The scope encompasses authenticity verification, hardware sensor diagnostics, and battery health telemetry. This procedure is intended for enterprise IT departments and authorized diagnostic technicians to ensure fleet compliance and hardware integrity.

3. Prerequisites & Tool Requirements

Hardware: Target Xiaomi device with minimum 30% battery charge.
Access: Active SIM card (for network-based USSD) or unlocked Dialer application.
Documentation: Manufacturer-provided IMEI/Serial number matching the physical chassis.
Environment: Static-safe work surface, high-speed network connectivity (if testing radio/WAN functions).
Safety PPE: Not required for non-invasive software diagnostics; standard ESD precautions apply if physical inspection is concurrent.

4. Roles & Responsibilities (RACI Matrix)

Role	Responsible	Accountable	Consulted	Informed
IT Technician	R
Operations Lead		A
Security Auditor			C
Inventory Manager				I

5. Step-by-Step Operational Procedure

Phase 1: Authentication & Device Identification

Launch native Dialer application.
Input *#06# to retrieve the device IMEI/MEID string.
Cross-reference the output against the physical SIM tray engraving and original purchase invoice.

Phase 2: Integrated Engineering Menu (CIT) Execution

Launch native Dialer application.
Input *#*#64663#*#* to trigger the Control Integrated Tool (CIT) menu.
Sequentially execute the following mandatory diagnostic tests:
- Hardware Version Test: Verify SoC, RAM, and internal storage parameters.
- Display Test: Run pixel/color uniformity checks.
- Touch Panel Test: Verify digitizer sensitivity across the 10-point grid.
- Battery Status: Monitor voltage/current discharge logs.

Phase 3: Telemetry & Network Verification

Input *#*#4636#*#* to access the Testing/Radio Info menu.
Audit "Phone Information" for signal attenuation (dBm) and cellular radio state.
Capture screenshot of "Usage Statistics" to identify potential bloatware or unauthorized background processes.

6. Quality Assurance & Verification Criteria

Audit Metric	Acceptance Benchmark	Failure Threshold
IMEI Matching	100% string alignment	Any variance in digits
Sensor Response	< 50ms latency	> 200ms latency
Battery Health	> 80% Full Charge Capacity	< 75% health flag
Software Integrity	Factory Stock ROM	Presence of bootloader unlock / Custom OS

7. Practical Troubleshooting Scenarios

Scenario A: Engineering Menu Inaccessible (Code fails to execute)

Diagnosis: Potential custom ROM or restrictive security patch level.
Corrective Action: Navigate to Settings > About Phone > All Specs. Tap "Kernel Version" repeatedly to unlock the diagnostic mode. If failure persists, perform a factory data reset (FDR) after data backup to restore kernel integrity.

Scenario B: Discrepancy between IMEI (USSD) and Physical Label

Diagnosis: Potential board swap or unauthorized hardware modification.
Corrective Action: Flag device as "Non-Compliant" in the Asset Management System. Immediately quarantine the unit. Request a formal investigation into the supply chain provenance.

Scenario C: Sensor Failure in CIT Test

Diagnosis: Physical hardware damage or ribbon cable disconnection.
Corrective Action: Cease testing. Tag device for physical teardown or Warranty Return Authorization (RMA) if the unit is within the service window. Do not attempt to bypass hardware calibration errors via software modification.
