What is OEM Bootloader?
The OEM bootloader is a type of bootloader that is specifically designed and developed by the Original Equipment Manufacturer (OEM) for their devices. It is a customized bootloader that is tailored to the device’s hardware and software specifications, allowing the device to boot up correctly and function as intended. The OEM bootloader is usually locked, which means that users cannot modify or replace it with a custom bootloader.
The OEM bootloader is responsible for loading the operating system and other essential software components on the device. It checks the integrity of the boot process and ensures that the device boots up securely and efficiently. The OEM bootloader also provides a layer of security by preventing unauthorized access to the device’s firmware and preventing malware from infecting the device during the boot process.
What is the difference between OEM Bootloader and Custom Bootloader?
The main difference between an OEM bootloader and a custom bootloader is the level of customization and flexibility they offer. An OEM bootloader is designed and developed by the OEM for their specific devices, whereas a custom bootloader is a third-party bootloader that can be installed on a device to override the OEM bootloader. A custom bootloader provides more flexibility and allows users to customize their device’s boot process, install custom ROMs, and access advanced features that may not be available on the OEM bootloader.
