Mobile Device Repair

Background

Being able to safely repair damaged mobile device exhibits in-house has become increasingly important for digital forensic units. Charging problems, cracked screens, faulty buttons or damaged data ports are common issues which may prevent successful data extraction. Digital forensic units need to be able to get devices working quickly and safely in order to prevent the inevitable delays, costs and continuity complications associated with taking a device outside the organisation to be fixed.

Faced with a “dead” device, a mobile examiner needs to be able to quickly identify the fault (or faults), confirm whether the repair(s) can and should be conducted in-house and establish the risks associated in undertaking
such work. Although YouTube is awash with “how to”  videos for device repair, undertaking such work without properly understanding the risks could easily mean that a vital evidential exhibit is further damaged by the attempted repair. Not only that, such videos assume that the actual fault with the device has been reliably identified.
Digital forensic units need staff who can quickly and accurately identify faults and then select the most pragmatic means of repair.

Course aims

Mobile Device Repair is a 4½ day course designed to teach mobile device examiners how to identify and repair common faults with mobile devices which might prevent data extraction. Students will learn a systematic and efficient approach to fault finding designed to quickly identify common obstacles to data extraction. The emphasis of the training is on performing the simplest and most cost effective repair possible in order to acquire data from the device. Students will gain experience in disassembling, repairing and re-assembling Android, iPhone, Windows Phone and feature phone devices. Importantly, the course will include instruction in the soldering techniques required to replace data ports which are integrated into the main circuit board of the device.

What you will learn

By the end of the course, delegates will be able to:

  • Identify and resolve charging and battery issues with mobile devices
  • Replace glued and non-glued screens on mobile devices
  • Replace modular and soldered components on mobile devices
  • Transplant circuit boards from damaged evidential exhibits into “donor” devices to facilitate data extraction
  • Explain and justify their actions in court

Who should attend?

This course is targeted at new or existing mobile device examiners. The course includes close work with small components and therefore requires good eyesight and a steady hand. Previous experience in handset disassembly and soldering would be beneficial but not essential.

Intermediate Mobile Device Repair

Background

Android and iOS devices typically need to be in a bootable state in order for data to be extracted using commercial forensic tools. Digital forensic units routinely encounter devices which are sufficiently damaged that extraction cannot take place – the device either fails to start at all or repeatedly displays the Apple logo (a “boot loop”). Although the replacement of broken screens and batteries within digital forensic units has become widespread, a subset of damaged devices require more complex fault-finding and repair techniques.

Course aims

The printed circuit board (PCB) within a mobile device is home to many tiny electronic components which work together to ensure that the device can boot and function normally. The failure of a single component on the PCB (for example, due to excess power) may lead to the device not powering at all, or “boot looping”.

Intermediate Mobile Device Repair is a 4½ day course designed to teach delegates how to identify and repair common board-level faults. Delegates will learn how to recognise components on a PCB and determine whether they have failed. They will then learn micro-soldering techniques to remove or replace faulty components in order to return a device to a bootable condition such that data can be extracted.

Delegates will gain vital hands-on experience of interpreting circuit board schematics and utilising them to locate short circuits which can then be repaired.

Delegates will primarily be working on iPhones during the course, however the techniques taught can also be used to troubleshoot and repair Android devices.

What you will learn

By the end of the course, students will be able to:

  • Identify specific components on a printed circuit board (PCB) and explain their function
  • Successfully diagnose PCB-level faults which prevent data extraction
  • Replace faulty PCB components including screen, touch and data port connectors
  • Diagnose and resolve short circuits on a PCB
  • Explain & justify their actions in court

Who should attend?

Delegates must have previous experience of mobile device repair and soldering. Ideally this will have been achieved by attending our Mobile Device Repair course.

Intermediate Mobile Device Repair sits alongside our Rework for Mobile Device Repair course. The fault-finding skills required to identify faulty chips is taught on Intermediate Mobile Device Repair – the replacement of those chips using hot air techniques is taught on Rework for Mobile Device Repair. Digital forensic units will gain maximum benefit where staff have attended Intermediate Mobile Device Repair and Rework for Mobile Device Repair.
