Can't re-lock my bootloader - Google Pixel 4 XL Questions & Answers

I just received my 6 pro and want to prepare my 4xl to sell. I flashed the latest software and the phone is 100% stock now and the bootloader will not lock. In fastboot I get a serial number when I run "fastboot devices". My platform tools are up to date, usb debugging is on. When I run "fastboot flashing lock" I get a string of fastboot command options. Any iseads? I've never had this happen.
Thanks for anything

Figured it out. Sdk must have been outdated

Relocking bootloader for sale

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.

Can't access full fastboot commands

Hi all, I was wondering if you know, after bootloader unlocking, why I can't access full fastboot commands as the one to remotely boot a recovery. "fastboot boot recovery.img" says "Failed: Command not allowed" and also does "fastboot oem ?" to list oem commands. OEM unlocking is permanently On , on the Dev Options and as I said before, bootloader is unlocked. But, I still can, I guess, flash boot, recovery etc. but I don't want to do it right now. I can tell it because so happened on my previous Huawei Phone and what's happening now on my P10 is the same thing. Thanks in advance.
Up, my ROM is VTR-L09C55B130 stock and I'm on Android 7.0

oneplus 3t android 7.1.1 OS 4.5.1 unlock bootloader

Hi Guys
I am unable to unlock my bootloader. I have downloaded adb and fastboot drivers. I connect device. run adb devices, device details are displayed. i then run command to reboot into the bootloader. it reboots into the bootloader. when i run fastboot unlock oem nothing happens.
I have enabled the developer options, USB debug, OEM unlock, Advanced reboot
is there something I am not doing right?
adb is working in your system but fastboot is not working.
Check your drivers properly, they are not installed properly.
search for how to install adb and fastboot drivers on windows. There is no problem in windows xp but in windows 10 as in my case, you need to activate the developer option in setting and manually install the drivers. Go to device manager and check if your device is showing as android device when you go to fastboot mode.

Did you type fastboot devices?
It should show you that your phone is connected.
Then you can run the unlock command.

Trouble with unlocking bootloader

Hi everyone, I recently decided to root my One Power XT1942-2 using Magisk. However, I'm stuck on the first step of unlocking the bootloader. The guides I've seen on this forum have basically been the following simple steps:
1. fastboot oem get_unlock_data
2. Take the unlock code, edit it into a single string, and send it to Motorola using their website.
3. Take the unlock code and run: fastboot oem unlock [unlock code]
Now, I haven't even been able to run the first command as fastboot just hangs. I rebooted into fastboot mode and verified that the device was connected (the serial number appears when running "fastboot devices"), but when running "fastboot oem get_unlock_data", the program just hangs.
Here are the device details:
Stock ROM (obviously)
May 1st security patch
USB Debugging and OEM unlocking enabled (checked and double-checked)
PC details:
Arch Linux (kernel 5.1.15-arch1-1-ARCH), x86_64
Using latest Android Platform Tools, as of June 28, 2019.
android-udev package installed.
I've also attempted doing the same on a Windows 10 PC, but to no avail. Is anybody else facing this issue, or is there something important I'm missing? TIA
I have used motorola 3G two times and 2G once i tried to unlock bootloader i hot same issue what u have to do are follow the all steps correctly find out form of moto 3G and try to unlock ur phone again theres something wrong like u are not opening the cmd command in same folder where u installed the adb fastboot

Unlocking bootloader issues

I'm having issues unlocking my bootloader on my new Pixel 4XL after following the pretty cut and dry instructions. I turn on OEM unlocking to allow the bootloader to be unlocked. I turn on USB debugging. I type a command in the PowerShell of SDK tools ./adb reboot bootloader. It takes me to the fastboot screen of the Pixel. But from there nothing else works. I type ./fastboot devices or ./fastboot flashing unlock, which returns waiting for any device or it doesn't return anything. It just goes back to the original command prompt. Device status says Locked in green. So I'm not sure why it won't unlock. Anyone have any suggestions?

Try using command prompt instead of PowerShell.
Try using a different cord.
Try using a different USB port.
Make sure your Platform Tools are up-to-date.
Make sure USB drivers are up-to-date.
fastboot flashing unlock should work
