Keep in mind that custom ROMs or modifications often require manual updates. Research your device’s policies and follow proper procedures to balance customization and receiving official updates.

Q- Is it necessary to unlock bootloader to flash stock ROM?

Ans. Standard approaches can install certified firmware updates without needing the unlocking of the bootloader to flash the stock ROM. If you wish to make more significant changes to the device or are working with modified ROMs, you might need to unlock the device. Always follow the manufacturer’s guidelines for your specific device.

Q- Is bootloader stored in BIOS?

Ans. No, the BIOS does not contain the bootloader. The device’s internal memory, or boot partition, has a separate piece of software known as the bootloader. The BIOS (or UEFI) handles the initial hardware initialization and then hands control to the bootloader to load the operating system.
