Screenshot of Device Manager, containing a Qualcomm device booted in the Emergency Download Mode. The Qualcomm Emergency Download mode, commonly known as Qualcomm EDL mode and officially known as Qualcomm HS-USB QD-Loader 9008 [1] is a feature implemented in the boot ROM of a system on a chip by Qualcomm which can be used to recover bricked smartphones.
Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed.

Fastboot is a communication protocol used primarily with Android devices. [1] It is implemented in a command-line interface tool of the same name and as a mode of the bootloader of Android devices. The tool is included with the Android SDK package and used primarily to modify the flash filesystem via a USB connection from a host computer.
When a system on a chip (SoC) enters suspend to RAM mode, in many cases, the processor is completely off while the RAM is put in self refresh mode. At resume, the boot ROM is executed again and many boot ROMs are able to detect that the SoC was in suspend to RAM and can resume by jumping directly to the kernel which then takes care of powering on again the peripherals which were off and ...
Odin is the Samsung proprietary alternative to Fastboot. There is no account of Samsung ever having officially openly released Odin, [3] though it is mentioned in the developer documents for Samsung Knox SDK [4] and some documents even instruct users to use Odin. [5]

A modern PC with a bus rate of around 1 GHz and a 32-bit bus might be 2000x or even 5000x faster, but might have many more gigabytes of memory. With boot times more of a concern now than in the 1980s, the 30- to 60-second memory test adds undesirable delay for a benefit of confidence that is not perceived to be worth that cost by most users.
The two rows of holes (labelled #3) are test points used during the manufacture of this USB memory key. Testpoints on a printed circuit board (labelled E34, E35, E36, …) next to teardrop vias. A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals. [1]
