나는이 명령을 실행하지 않고도 몇 달 동안 휴대 전화를 가지고 있고, 여러 펌웨어, ROM 및 OTAS로로드 중입니다. 그것은 무엇을합니까?
무엇을 알고있는 것은 "Fastboot OEM 잠금 해제"가 확인 화면을 표시하고 내 장치 데이터를 지우려면 "Fastboot OEM 잠금 해제"가 내 전화기에 펌웨어를 깜박이는 첫 번째 단계입니다.
나는 전화를 retocking하지 않고
I've had my phone for months, loading with several firmware, ROMs and OTAs, without ever running this command. What does it do?
What I know is that "fastboot oem unlock" displays the confirmation screen and obliges me to wipe my device data, and that "fastboot oem unlock" is the first step to flashing firmware unto my phone.
Am I okay not relocking my phone?
Simply put, fastboot oem lock puts your bootloader into a mode that prevents you from overwriting your recovery image, without a subsequent fastboot oem unlock. This serves as a security precaution, primarily where the default recovery and firmware is installed.
....you can rest assured that, under this configuration, no one can take your phone and, say, bypass a screen lock by installing a custom firmware where the security considerations are different.
Note that as this merely locks in your recovery, and then again only from bootloader-overwrites, this is most useful where the recovery is stock, and the installed ROM is an official one that has no security vulnerabilities. This is important because in most recoveries, and in some ROMs, there are ways to clandestinely access data via USB, bypass security settings with fixed button presses or unpatched backdoors, or install custom recoveries.

I have seen quite of few people screw up their devices by not knowing what they are doing. So I am making this thread to simply tell people not familiar with fastboot what they should and should not do.
Fastboot oem unlock will unlock your bootloader and do a complete wipe of your device. As far as I know the only way for something to go wrong here is if you're device is low on battery and shuts off during the process. Either plug it in or have a "good" amount of juice left in your battery. To be 100 percent sure plug it in.
Before I get into oem lock IMHO you should only use this command for one thing only. Getting the device ready to send into motorola for the LGT upgrade or a another warranty repair or some sort. When done properly it is completely safe but there is no reason to do to go back to "stock".
Fastboot oem lock. Do not issue this command unless you are absolutely sure you have the correct software on your device. The correct software is what you get from the motodev site for your device. You need the official sofware images for your specific device AND REGION. If it is not released then DO NOT re-lock the device. If you have a OTA installed you will need to flash back to the motodev images first.
I had to use fastboot oem lock on my Galaxy Nexus. At my unlocked device I couldn't see the filesystem in explorer (MTP).
The command locks your bootloader. What the consequences are really depends on your device. Most devices enable signature-verification for the boot partition (kernel) which prevents you from booting any kernels not signed by device manufacturer (unless you exploit some security breaches like 2nd boot). They also disallow you to flash any partition via 'fastboot flash' command, but not on all devices.
So no, you are not okay with relocking your phone: If you use custom firmware, you typically use a custom kernel and in this case, re-locking your bootloader via 'fastboot oem lock' will put your device in a state where it will not boot anymore! Be careful with that.
