Mobile Hardware and Software Repairing Course

Lesson 1 • Electrostatic Discharge and Safety Protocols

Establishes ESD prevention, chemical safety, and workspace hazard controls. Safe habits introduced here apply throughout every hands-on chapter.

Lesson 2 • Core Hardware Components Explained

Identifies every major internal component and its function within the device. Provides the anatomical vocabulary needed for all subsequent repair chapters.

Lesson 3 • Mobile Device Categories and Market Overview

Covers smartphones, tablets, and feature phones by form factor and use case. Establishes the device landscape technicians encounter daily in repair shops.

Lesson 4 • Reading Schematics and Service Manuals

Teaches interpretation of circuit diagrams, block diagrams, and OEM service documentation. Accurate schematic reading is prerequisite for board-level diagnosis.

Lesson 1 • Hand Tools for Disassembly

Covers screwdrivers, spudgers, opening picks, and pry tools by type and application. Correct tool selection prevents cosmetic and structural damage during teardown.

Lesson 2 • Workspace Organisation and Ergonomics

Designs an efficient, ESD-safe, and ergonomically sound repair bench layout. A well-organised workspace reduces errors and improves throughput.

Lesson 3 • Measurement and Diagnostic Instruments

Teaches use of multimeters, oscilloscopes, and DC power supplies for fault isolation. Accurate measurement skills underpin every electrical diagnosis task.

Lesson 4 • Soldering and Rework Equipment

Introduces soldering stations, hot-air rework stations, and infrared reflow systems. Proper equipment setup is foundational to all board-level repair work.

Lesson 1 • Pre-Disassembly Assessment and Preparation

Covers intake inspection, data backup reminders, and power-off verification before opening. Proper preparation prevents data loss and secondary damage.

Lesson 2 • Screen and Display Assembly Removal

Teaches heat application, adhesive softening, and safe panel separation techniques. Display removal is the most common first step in most repair workflows.

Lesson 3 • Internal Component Extraction

Guides removal of batteries, cameras, speakers, and charging ports in correct sequence. Sequence discipline prevents connector and bracket damage.

Lesson 4 • Reassembly and Quality Verification

Covers torque-correct screw reinstallation, connector seating, and post-build functional tests. Reassembly quality directly determines repair success rate.

Lesson 1 • Screen Replacement Procedures

Executes OEM-grade screen swaps including adhesive application and connector alignment. Correct procedure prevents backlight bleed, gaps, and hinge stress.

Lesson 2 • Display Technology Deep Dive

Compares LCD, AMOLED, and LTPO panel technologies by construction and failure modes. Technology knowledge guides correct replacement part selection.

Lesson 3 • Touch Digitizer Fault Diagnosis

Identifies ghost touch, dead zones, and unresponsive areas through systematic testing. Accurate fault isolation avoids unnecessary full-assembly replacement.

Lesson 4 • OLED Burn-In and Pixel Repair

Addresses software-based pixel refresh tools and hardware replacement thresholds for OLED. Technicians learn when repair is viable versus when replacement is required.

Lesson 1 • Post-Replacement Charging Validation

Tests charging speed, thermal behaviour, and OS-reported capacity after battery installation. Validation confirms the repair meets performance and safety standards.

Lesson 2 • Battery Removal and Installation

Covers adhesive pull-tab, solvent-assisted, and spot-welded battery removal techniques safely. Correct removal prevents puncture, fire, and PCB damage.

Lesson 3 • Battery Health Diagnostic Methods

Uses built-in OS tools, third-party apps, and bench analysers to measure capacity and cycle count. Accurate health data supports repair-vs-replace decisions.

Lesson 1 • Power Management IC Diagnosis

Uses schematics and multimeter to trace PMIC faults causing no-charge or no-power conditions. PMIC diagnosis requires schematic literacy from earlier chapters.

Lesson 2 • Charging Port Types and Failure Modes

Identifies USB-C, Lightning, and Micro-USB port construction and common mechanical faults. Port type knowledge determines correct replacement part and technique.

Lesson 3 • Charging Port Replacement Procedures

Executes flex-based and board-mounted port replacements with correct soldering technique. Port replacement is among the highest-volume repairs in any shop.

Lesson 4 • Power-On Failure Systematic Diagnosis

Applies a structured no-power diagnostic flowchart using bench supply current readings. Systematic flowcharts reduce diagnosis time and prevent component misidentification.

Lesson 1 • Firmware and OS Update Fundamentals

Explains OTA updates, full firmware packages, and version compatibility requirements. Firmware knowledge prevents bricking during software repair attempts.

Lesson 2 • Data Backup and Recovery Techniques

Performs cloud, local, and chip-level data backup before and after software interventions. Data preservation is a primary customer expectation in every software repair.

Lesson 3 • Bypassing Locks and Activation Issues

Addresses FRP bypass, MDM removal, and iCloud Activation Lock within ethical and legal boundaries. Technicians must verify device ownership before any lock removal.

Lesson 4 • iOS Restore and Recovery Procedures

Executes iTunes and Finder restores, DFU mode entry, and 3uTools-assisted recovery. iOS recovery requires precise mode entry to avoid activation lock complications.

Lesson 1 • Micro-Soldering Fundamentals

Builds iron control, solder flow, and flux discipline for work on 0201 and smaller components. Micro-soldering precision is the highest technical skill in mobile repair.

Lesson 2 • Trace Repair and Jumper Wiring

Restores broken PCB traces using conductive ink, copper tape, and 40 AWG jumper wire. Trace repair recovers boards that would otherwise be scrapped.

Lesson 3 • BGA Chip Removal and Reballing

Removes BGA ICs with hot air, cleans pads, and applies fresh solder balls for reinstallation. BGA work requires mastery of all prior soldering and schematic skills.

Lesson 4 • Water Damage Board Restoration

Applies ultrasonic cleaning, corrosion removal, and component-level inspection to water-damaged boards. Systematic restoration maximises recovery rate on liquid-damaged devices.
