Problems solved by technology

[0002] Android system firmware is easy to obtain on the Internet, and it is often cracked and tampered with by people with ulterior motives, which will affect the interests of users, manufacturers and other parties.
[0003] The Internet is becoming more and more developed, and a lot of information can be obtained from it. When the security technology was not perfect in the early days, it was frequently seen that the Android system firmware of some manufacturers was cracked and modified by netizens, and all the applications bound to the firmware were deleted and replaced with other applications. , the reason is that in related technologies, only simple protection measures are taken for boot.img
