Students learn how to make a JTAG connection to a locked device by primarily soldering to the TAPs (Test Action Points) in order to access the physical memory on the device. Connecting via a Molex Connection or using a custom JIG is also taught. Some newer phones may not be JTAGable.
Students learn how to remove the chip from board using various techniques and prepare the board to do a read. Students also learn the fundamentals of the various memory structures found on devices ranging from smartphones, tables and SSD drives.
ISP is a good choice for labs seeing newer phones unsupported by JTAG that contain an eMMC or eMCP chip. It is a non-destructive process like JTAG, but it requires very fine precision soldering and either excellent vision or proper magnification.
