Part 1: What is Checkm8?

Due to its capacity to get through Activation Lock on specific iPhone and iPad models, Checkm8 is a bootrom exploit that has attracted a lot of interest in the iOS community. It makes use of a weakness in the bootrom, a read-only memory chip that launches the operating system and initializes the hardware of the device. So, the question is can checkm8 bypass icloud? Yes, Checkm8 allows users to bypass iCloud Activation Lock, enabling them to access and use a device that would otherwise be locked.
