What is Maskrom mode?

Maskrom mode, also known as Loader mode, is a special boot mode typically used for recovering or repairing problematic devices. This mode allows users to interact directly with the device's hardware without needing the operating system. In Maskrom mode, users can communicate with the device via a computer or other interface and execute a series of commands to resolve issues with the device.
