Advanced Flasher Box and Bootloader for Mobile Forensics


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, 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 for the lower-cost devices. TeelTech’s 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.

Students will perform a variety of practical exercises using both the take-home boxes, as well as the Octoplus Box. For this reason, we request students bring their own computers, so as to get a better understanding of the often challenging installation procedures of the boxes.

Teel Tech did a spot-on job of making sure we were ready to take our laptops back to work and be able to duplicate and expand on the knowledge we gained in class. If a prospective student is unsure about the workings of Odin, TWRP, CWM, or flasher boxes, they can be assured they will leave this class with a solid understanding of these processes.
