一加Ace/OnePlus 10R 如何通过命令行工具判断bootloader是否解锁

可能是由于MTK芯片的原因，和之前的一加机型都不太一样，不能使用fastboot oem device-info来获取bootloader是否解锁的信息。

而应该使用fastboot getvar

比如直接使用fastboot getvar all，可以获取到很多信息

上面的信息如下

(bootloader)    off-mode-charge: 1
(bootloader)    slot-retry-count:b: 1
(bootloader)    slot-retry-count:a: 1
(bootloader)    slot-successful:b: yes
(bootloader)    slot-successful:a: yes
(bootloader)    slot-unbootable:b: no
(bootloader)    slot-unbootable:a: no
(bootloader)    slot-count: 2

(bootloader)    partition-type:boot_a: raw
(bootloader)    partition-size:boot_b: 4000000

(bootloader)    has-slot:boot: yes
(bootloader)    partition-type:lk_b: raw
(bootloader)    partition-type:lk_a: raw
(bootloader)    partition-size:lk_b: 500000
(bootloader)    partition-size:lk_a: 500000
(bootloader)    has-slot:lk: yes
(bootloader)    is-userspace: no

其中(bootloader) unlocked: yes这一行，就是bootloader已经解锁的意思。

进一步的，也可以直接使用fastboot getvar unlocked来只获取bootloader解锁的信息。
