ROM is the abbreviation of ROM image (read-only memory image), which is often used in the circle of mobile phone customization system players. Generally, the process of flashing a mobile phone is the process of writing a read-only memory image (ROM image) into the read-only memory (ROM). Common ROM images have formats such as img, zip, etc. The former is usually flashed in through the data line with the fastboot program (wire flashing), and the latter is usually flashed in from SD (card flashing) in recovery mode, so img mirroring is also called line flashing. Package, zip image is also called card swipe package. Domestic custom system developers often fall into the debate about whether their products should be called OS or UI. In order to avoid such disputes and express humility, they will call themselves ROM. Many custom system players will also refer to the custom system as ROM.
