Lesson 2 • Mobile Operating Systems Basics

Introduces Android and iOS architectures at a functional level. Connects OS behaviour to hardware interaction, preparing students for software-related diagnostics.

Lesson 3 • Mobile Phone Hardware Overview

Identifies and describes every major internal component and its function. Builds the vocabulary needed for diagnosis and parts ordering throughout the course.

Lesson 4 • Industry Standards and Safety Regulations

Covers electrostatic discharge precautions, workplace safety standards, and environmental disposal requirements. Ensures students operate safely and in compliance with industry norms.

Lesson 1 • Disassembly Techniques by Form Factor

Teaches opening procedures for glass-back, plastic-back, and modular devices using appropriate tools. Correct technique prevents cracked screens and torn flex cables.

Lesson 2 • Component Removal and Handling

Covers safe removal of batteries, cameras, charging ports, and logic boards. Proper handling prevents ESD damage and preserves component reusability.

Lesson 3 • Reassembly and Quality Verification

Guides students through reverse assembly with torque awareness and adhesive reapplication. Verification steps confirm full functionality before returning a device to a customer.

Lesson 1 • Diagnosing Display Faults

Teaches visual and software-based methods to distinguish hardware from software display failures. Accurate diagnosis prevents unnecessary part replacement and reduces repair cost.

Lesson 2 • Touch Digitizer Calibration and Testing

Covers software calibration steps and manual touch-response testing after replacement. Ensures the repaired device meets original touch sensitivity and accuracy standards.

Lesson 3 • Screen Replacement Procedures

Walks through full screen assembly replacement from heat separation to final adhesive sealing. Students practise on multiple device models to build speed and accuracy.

Lesson 4 • Display Technology Fundamentals

Compares LCD, AMOLED, and OLED panel characteristics relevant to repair decisions. Understanding panel type guides correct replacement sourcing and handling.

Lesson 1 • Charging Port Replacement and Soldering

Teaches through-hole and surface-mount charging port replacement with proper soldering technique. Students practise on donor boards before working on customer devices.

Lesson 2 • Battery Chemistry and Safety

Explains lithium-ion and lithium-polymer cell behaviour, failure modes, and safe handling rules. Safety knowledge prevents fires and injuries during battery work.

Lesson 3 • Charging Port and Circuit Diagnosis

Identifies faults in USB-C, Lightning, and wireless charging systems using electrical testing. Distinguishes port damage from charging IC failure to select the correct repair path.

Lesson 4 • Battery Health Diagnosis

Uses built-in OS tools and third-party apps to measure capacity, cycle count, and charge health. Accurate assessment helps technicians justify replacement to customers.

Lesson 1 • Sensor Diagnosis and Replacement

Addresses proximity, ambient light, accelerometer, and gyroscope faults using diagnostic apps. Sensor failures affect call behaviour and screen rotation, requiring accurate identification.

Lesson 2 • Camera System Architecture

Explains front, rear, and multi-lens camera configurations and their flex cable routing. Understanding the system layout prevents damage during removal and reinstallation.

Lesson 3 • Speaker, Microphone, and Earpiece Repair

Covers audio component testing, removal, and replacement for loudspeakers, earpieces, and microphones. Audio faults are isolated using tone generators and recording tests.

Lesson 4 • Camera Module Replacement

Guides removal and installation of rear and front camera assemblies with alignment precision. Misalignment causes optical distortion, so correct seating is verified before closure.

Lesson 1 • Firmware Flashing and OS Restoration

Covers stock firmware flashing on Android and iOS using manufacturer and third-party tools. Students restore bricked devices and resolve persistent software faults.

Lesson 2 • Network and Connectivity Troubleshooting

Diagnoses Wi-Fi, Bluetooth, cellular, and GPS failures at the software and hardware level. Students use diagnostic tools to isolate antenna, modem, and settings-related faults.

Lesson 3 • Software Fault Identification

Distinguishes hardware failures from OS crashes, app conflicts, and corrupted system files. Accurate software diagnosis saves time and prevents misdiagnosis-driven part orders.

Lesson 4 • Bootloader and Recovery Operations

Explains bootloader unlock procedures, custom recovery installation, and their repair applications. These skills enable advanced software repairs on Android devices.

Lesson 1 • IC Reballing and Replacement

Covers BGA chip removal, pad cleaning, reballing with stencils, and precise chip placement. These skills enable repair of power ICs, audio ICs, and baseband processors.

Lesson 2 • Board-Level Fault Diagnosis and Repair

Applies multimeter, DC power supply, and thermal camera techniques to locate shorts and open circuits. Students complete end-to-end board repairs from diagnosis to verification.

Lesson 3 • Schematic and Boardview Reading

Introduces schematic symbols, net names, and boardview software for locating components on the PCB. Schematic literacy is essential for tracing faults to their root cause.

Lesson 4 • Soldering Equipment and Setup

Covers station calibration, tip selection, flux types, and solder alloy properties for fine-pitch work. Proper setup is the foundation of consistent, damage-free microsoldering.

Lesson 1 • Biometric System Repair and Pairing

Addresses fingerprint sensor, Face ID, and under-display biometric repair with pairing requirements. Students understand which repairs require OEM tools and how to communicate limits to customers.

Lesson 2 • Repair Verification and Quality Assurance

Establishes a comprehensive post-repair testing protocol covering all device functions before customer return. Consistent QA reduces callbacks and builds technician reputation.

Lesson 3 • Multi-Fault Device Diagnosis Strategy

Teaches a structured triage approach for devices with multiple simultaneous failures. Prioritising faults by root cause prevents wasted parts and incomplete repairs.

Lesson 4 • Foldable and Emerging Form Factor Repairs

Introduces hinge mechanisms, flexible display handling, and unique disassembly challenges of foldable phones. Students gain awareness of next-generation device repair requirements.
