Qualcomm Emergency Download Mode
The Qualcomm Emergency Download mode, commonly known as Qualcomm EDL mode and officially known as Qualcomm HS-USB QD-Loader 9008 is a feature implemented in the boot ROM of a system on a chip by Qualcomm which can be used to recover Brick (electronics), bricked smartphones. On Google's Pixel 3, the feature was accidentally shown to users after the phone was bricked. Device support For a device to support EDL it must be using Qualcomm hardware. The Qualcomm Snapdragon, Snapdragon family is very widely used. Access ADB The Android Debug Bridge can be utilized to get access to EDL mode, with the command adb reboot edl. Windows The Qualcomm Product Support Tool (QPST) is normally used internally by service center executives for low-level firmware flashing to revive Android devices from a hard-brick or to fix persistent software issues. To flash the firmware, the tool communicates with supported devices via EDL. The QPST has not been officially released by Qualcomm. Linux ...

Boot ROM
Boot ROM is a piece of read-only memory (ROM) that is used for booting a computer system. It contains instructions that are run after the CPU is reset to the reset vector, and it typically loads a bootloader. There are two types of boot ROM: a mask boot ROM that cannot be changed afterwards, and a writable boot ROM such as an EEPROM or a flash memory chip. Purpose Upon power up, hardware usually starts uninitialized. To continue booting, the system may need to read a bootloader from some peripheral device. It is often easier to implement routines for reading from external storage devices in software than in hardware. A boot ROM provides a place to store this initial loading code, at a fixed location immediately available to the processor when execution starts. Operation The boot ROM is mapped into memory at a fixed location, and the processor is designed to start executing from this location after reset, according to the processor's reset vector. The boot ROM is eith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System On A Chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or Electronics, electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with computer memory, memory, input/output, and computer data storage#Secondary storage, data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing Performance per watt, power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as Universal Flash Storage, eUFS or eMMC, which may be stacked directly on top of the SoC in a Package on a package, package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qualcomm
Qualcomm Incorporated () is an American multinational corporation headquartered in San Diego, California, and Delaware General Corporation Law, incorporated in Delaware. It creates semiconductors, software and services related to wireless technology. It owns patents critical to the 5G, 4G, CDMA2000, TD-SCDMA and WCDMA mobile communications standards. Qualcomm was established in 1985 by Irwin M. Jacobs, Irwin Jacobs and six other co-founders. Its early research into CDMA wireless cell phone technology was funded by selling a two-way mobile digital satellite communications system known as Omnitracs. After a heated debate in the wireless industry, CDMA was adopted as a 2G standard in North America, with Qualcomm's patents incorporated. Afterwards, there was a series of legal disputes about pricing for licensing patents required by the standard. Over the years, Qualcomm has expanded into selling semiconductor products in a predominantly fabless manufacturing model. It also develope ...

Brick (electronics)
A brick (or bricked device) is a mobile device, game console, router, computer or other electronic device that is no longer functional due to corrupted firmware, a hardware problem, or other damage. The term analogizes the device to a brick's modern technological usefulness. "Brick" is also used as a verb to describe a device entering such a state. Cause and prevention Bricking a device is most often a result of interrupting an attempt to update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable. The risk of corruption can be minimized by taking all possible precautions against interruption. Bricking a device may also be done intentionally as punishment for severe transgressions involving its use, but this is exceptionally rare and typically only done as a last resort.

Smartphone
A smartphone is a mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and Streaming media, streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps. Smartphones are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems, access to the internet, business applications, Mobile payment, mobile payments, and multimedia functionality, including music, video, mobile gaming, gaming, Internet radio, radio, and Mobile television, television.

Android Debug Bridge
The Android Debug Bridge (commonly abbreviated as adb) is a programming tool used for the debugging of Android-based devices. The daemon on the Android device connects with the server on the host PC over USB or TCP, which connects to the client that is used by the end-user over TCP. Made available as open-source software under the Apache License by Google since 2007, its features include a shell and the possibility to make backups. The adb software is available for Windows, Linux and macOS. It has been misused by botnets and other malware, for which mitigations were developed such as RSA authentication and device whitelisting. Features Features of adb include copying files from the host computer, installing apps, viewing logcat output, getting a Unix shell, and rebooting into Qualcomm EDL mode. For example, Android applications can be saved by the command backup to a file. It also includes support for the Java Debug Wire Protocol. Some graphical interfaces have been m ...
