TeelTech Advanced Flasher Box & Bootloader Forensics

In this five day class, participants will gain an in-depth understanding of today’s most useful and effective flasher boxes and bootloader utilities to unlock and acquire mobile device memory. Applicable to both high-end Android devices, such as the Samsung S6 and similar, down to the low-end devices from manufacturers such as BLU and others that use the low-cost MediaTek and Chinese chipsets, such tools and techniques enable examiners to expand their options when addressing such devices.

In the Flasher Box portion of the class, students will gain an overview of today’s best Flasher Box tools, and install and use them to image devices. A selection of today’s most useful boxes will be supplied for students to install and image devices, and a complimentary collection of boxes will be provided to the students to take home with them after class.

In the bootloader part of the class, students learn how bootloaders are applied to access device partitions for unlock or bypass lock purposes. Lessons in using ADB Commands,
identifying whether a phone has a FRP lock and how to bypass it, and use CWM and TWRP to unlock a device, access memory and image the device.

Practical lessons on a variety of devices will be provided, devoting plenty of time to hands-on work.
