A *.CPB file is a firmware package commonly associated with cryptocurrency miners, especially those manufactured by Goldshell. It's primarily used for updating the miner's firmware to enhance performance, fix bugs, or add new features. The internal structure of *.CPB files is proprietary and specific to Goldshell devices. While less common, *.CPB can also refer to Qualcomm firmware upgrade images used with specific flashing tools like Infinity-Box CM2MTK. This file format is classified as Firmware.

CPB file format:

To view or edit CPB files you need to know the file format, because it determines how the data in this file is stored. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file.
