20 1606 1 1 update: add 2 q &；; What the hell is AQ 1:boot loader locked? A 1: It is a lock that restricts you from directly loading and rewriting the system partition Q2: What is the state of the lock? What does the difference mean? A2: According to the unlocking method, it can be divided into the following states. According to the intuitive explanation, it should be clear, but what Xiaomi's Bootloader has not yet achieved is that it can directly obtain the lock status through the fastboot command like other friends, but one thing is certain: the step from lock to unlock is an irreversible operation-lock-unlock-relock-relock 20 16060655. I hope it can help you. The integral limit of method 2 has been cancelled. You can lower the integral requirement of Method 3 by replying to check. Q 1: Will the opportunity to swipe your card in this way affect the Bootloader lock or account lock? A 1: If the device contains a boot loader lock and an account lock when it is released, if the device does not have a boot loader lock and an account lock when it is released, it will not have any impact on the existing boot loader lock and account lock. However, according to HTC's previous practice, the firmware may be improved later. If the unlocked version is swiped by force, it will not be able to enter the system (machines with subsequent locks and no Bootloader locks at the time of release: Xiaomi note Top Matching and Xiaomi 4c)Q2: If it was unlocked before, can it be swiped back to the unlocked state through 9008? A2: The unlocked post has been written clearly. As long as you apply for unlocking and successfully unlock it, it will be permanently marked in the background. According to the policies of Huawei, HTC, Sony and other manufacturers, you can't enjoy the warranty after unlocking, but you can't return to the unlocked state after unlocking. So it's up to you whether to unlock it or not. Q3: Why can't some models use Method 2? A3: This has not been measured. According to the truth, most locks should be available. If you really encounter a prompt error, it is suggested that you can try to brush the machine with Xiaomi Assistant. Of course, Xiaomi Assistant will not automatically restart after brushing. If you have special needs, you can use MiFlash to brush the required version after Xiaomi Assistant finishes brushing the machine. 20 1605 14 update: the title has been changed. After all, it is not only the implanted software that needs to be rescued.
