Hello hopefully someone can lend me a hand. I am trying to relock my bootloader on my moto x pure edition 2014. I have downloaded the correct recovery package from Motorola directly. I issue the commands that are needed fastboot oem lock begin and then flash the firmware and then fastboot oem lock. After fastboot oem lock I get SSL error you must enter fastboot oem lock begin before lock is what is shows on the terminal windows for fastboot. On the the device screen if shows cannot validate system image although it is the correct system image. I have tried using the fastboot directly out of the Motorola software I downloaded as suggested by another user and still get the same error. I have worked on this for hours with no avail. Does anyone have any experience in this with the same problem? Thanks
Did you try following the steps listed on Motorola's website?

I believe the "fastboot oem lock begin" was only needed for older devices.
Alright, I somewhat hate Android 6.0, and that's because of my hard time rooting my Nexus 6, which is, at this point, becoming immensely irritating. If I'm allowed to do so here, since this is a Q&A board, I need to ask how the hell to root this thing, because of Android's new thing where I have to install a custom kernal to get root.
All I really know, now, ids that I need to unlock the bootloader of the phone, which I've been trying to do (installed SDK's platform tools, made sure my Nexus 6 Windows drivers are installed, but when I open a command prompt to unlock the bootloader, I'm met with a, "no devices found," response, so I have no clue what to do, and need some help, because with how many tutorials I've looked up for how to do this, and none of them working, I'm about heady to break my monitor. If anyone can explain what the **** I'm doing wrong, or link to a tutorial for how to unlock the bootloader, that actually explains what's needed to do so, it'd be appreciated.

This is how i always root the phone:
- Enable usb debugging and ENABLE OEM UNLOCKING in developer options
- Reboot into the bootloader and type fastboot oem unlock and let the phone boot up
- Flash TWRP in fastboot
- Go to recovery and flash a modified boot.zip (all custom kernels will do)
- Flash the latest superSU.zip, also in recovery
- Done
Here is a tut for the adb setup (Windows) http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/.
- Reboot into the bootloader and type fastboot oem unlock and let the phone boot up
That's my problem. Opening up the command prompt and typing, "fastboot OEM unlock," does absolutely nothing. No prompts come up on the phone. It just sits there, and doesn't do anything.

Do you see a serial number in fastboot if you type: fastboot devices? If not your drivers aren`t installed correctly or adb isn`t setup correctly.

I'm using Windows Vista, so I had to add an underscore, and type, "fastboot oem_unlock," to get the bootloader unlocked. Everything is restoring, now, however, I'm wondering if I'll have to do something similar with flashing TWRP, and the kernal I'm attempting to install. I don't know programming or cmd commands.

You only have to flash the TWRP.img file in fastboot, the rest (boot/superSU) are zip files to be flashed in recovery. I have no experience with Vista so can`t help you there, maybe there is some info about it on Google/YouTube.

To regain root, simply use
Code:
fastboot boot
and drag and drop the TWRP file and press enter, and install root of your choice.

This is 2 months late, but if you're still looking for a possible solution, this is what I did:
1.) Download the tools you need here: https://developer.android.com/studio/releases/platform-tools/ and extract
2.) Install LG United Mobile Drivers from here: https://lg-united-mobile-driver.en.lo4d.com/. I recommend uninstalling previously installed LG G4 drivers from Device Manager and then reinstall from that page. You may need to install additional drivers once you connect your G4 to your computer.
3.) In Developer Options, make sure you have "Enable OEM unlock" checked and "USB Debugging"
4.) Open a command prompt in the tools directory (hold shift, right-click inside the folder, and click "open command prompt here." If you've authorized your device to be recognized by your computer (two prompts should popup: one to allow USB connection and another to allow USB debugging), your device should be listed if you enter the command "adb devices"
5. Enter "adb reboot bootloader"
6. Once the phone has rebooted into the bootloader, you should be at the stage where you get the text on your phone, as you described. Enter "fastboot oem unlock"
7. Check if you've unlocked the bootloader: "fastboot getvar unlocked"
8. If successful, you can then go on to flash TWRP onto the recovery partition and root your phone by flashing Magisk from there.
Hello .. I have a LG G4 811 t mobile32GB phone, what is the appropriate flash?
In the past I have unlocked the boot loaders for Pixel, Pixel 2 and Pixel 3 always on first try and I know how to do it. But my new Pixel 5, US unlocked version, arrived today, will not boot loader unlock. I have dev options enabled, USB debugging on, and allow OEM unlock set on. I'm using a Mac so my fastboot commands are ./fastboot___. With the Pixel 5 in fastboot mode, ./fastboot devices gives a correct response, the device responds with its serial number. But then with ./fastboot flashing unlock nothing happens. Just sits there. When I give the command the terminal cursor moves down to the next line but there is no response from the device. I've turned off, rebooted, repeated multiple times, same result. I tried the old ./fastboot oem unlock and that does not work either (as expected).
Has anyone else encountered this? Advice?
Using latest adb/fastboot? I had problems flashing/unlocking the device because I tried it with an old adb/fastboot version.
If that doesn't help then try using another computer. Often windows doesn't (I know you're probably using mac) correctly recognize devices in fastboot mode, which is why you have to manually add google drivers in windows device manager if 'fastboot devices' doesn't detect the device.
Good luck!

Thanks, Michael. I am using the latest SDK with current platform-tools, and don't have another computer. Tried several different cables, no luck. However, I've decided to forgo unlocking the BL and just set it up locked. I no longer use root nor custom ROMs and future TWRP is very unlikely so I'm going to stay boot loader locked for the first time in many years. Will see how it goes. I really have not needed/used it since OS10.
Thanks again.
Hello,
I have a brand new Xperia XZ1 Compact (G8441) and I'm setting out to install LineageOS on it.
I understand the first step is to unlock the bootloader. I have followed Sony's instructions here but I get this error when I run the fastboot unlock command:
./fastboot oem unlock 0xE8475F4F6417A194B (I also tried without the 0x)
FAILED (remote: 'Incorrect format for unlock data')
I then tried following a different article at getdroidtips but I get this error:
./fastboot -i 0x0fce oem unlock 0xE8475F4F6417A194B
fastboot: invalid option -- i
I'm also confused if I even have to run the above commands because I managed to enable "OEM Unlock" from the Developer options menu. This OEM Unlock option wasn't initially visible when I first enabled Developer Options so I'm curious why it suddenly appeared.
Any help would be greatly appreciated, thank you!
I was able to get it to work on a windows machine, after installing this:
