At its core, is not a single piece of software, but a class of utilities that bypass standard consumer safeguards to allow parallel programming of NAND/eMMC/UFS storage.
In a factory producing 10,000 units a day, speed is everything. A "flashing station" will typically have a technician managing an 8-port USB hub. Using Engineer Mode, they can flash the OS, recovery, and modem firmware to 8 phones simultaneously in the time it would take to flash one.

In an engineering environment, a single host PC is often connected to a USB hub, which in turn connects to multiple target devices. The download tool must be able to:
