Detailed explanation-1: -Once data is written on a ROM chip, it cannot be removed. Almost every computer incorporates a small amount of ROM that contains the start-up firmware. This boot firmware is called the basic input/output system (BIOS).
Detailed explanation-2: -Go to backup and then backup data only(u will see tick-marks and u will be able to choose what exactly u wanna backup). Then flash a new rom and restore backed up data. And u can backup the whole rom and restore back if u don’t like the new rom.
Detailed explanation-3: -Because ROM is read-only, it cannot be changed; it is permanent and non-volatile, meaning it also holds its memory even when power is removed. By contrast, random access memory (RAM) is volatile; it is lost when power is removed.
Detailed explanation-4: -Flashing a new ROM can swipe all the internal data on your device ( not everytime) but keeping the backup of your stock ROM and all the data in advanced is must so that after flashing the ROM you will not lose any of your data.
