[Completed] [Q] Fastboot doesn't recognize moto g 4g on linux

I have a Moto G 4g. ADB recognizes the cell and I can restart it in fastboot mode, but when I check in the terminal with:
Code:
fastboot devices
Nothing appears, and if I go on with
Code:
fastboot oem get_unlock_data
It gets stuck at
Code:
< waiting for device >
I tried as a user and as root on an Archlinux machine with android-udev rules as shown in the Archlinux wiki (sorry, i can't put the link). AP Fastboot fast boot menu shows that the cell is locked.
Hi,
You can try a different cable, or USB port on the pc...or even a different pc. Until fastboot devices detects your device, there's nothing you can do.
Reinstall drivers...and you are on the bootloader mode right?
If none of that helps, you can ask in your device section for help....

[Completed] Can't unlock bootloader (iOcean X8 Mini)

Hello,
A friend of my asked me to install a new version on his iOcean X8 Mini.
After a few minutes into the process, I discovered that I couldn't modify anything at all.
Problems start occuring when I enter Fastboot via ADB (I power up the phone, connect it to PC, give it permission to use Android USB Debugging, then via 'adb rebeoot fastboot' I enter the Fastboot menu). Every command I enter here returns 3 dots just doing nothing. My command prompt is unusable after entering a command (for example 'fastboot oem unlock').
I've tried to push a ROM via ADB but this isn't working as well since it returns something like 'no permission' when trying to install, but I figured this was due to the locked bootloader.
Searched all over the internet for solutions, but so far nothing has really worked. What I somehow did mange to do is root the device (don't know if it was by default, I assume not), via RootGenius.
Anybody got any experience with this, and perhaps know some steps I can undertake to indeed unlock the bootloader of this phone?
Thanks in advance!

[Completed] LG H650E Zero - device not found in adb tool

HI!
1. I have an LG H650E Zero and i'm trying to control it using adb in order to pull build.props but with no success.
The system display a " Device not found " message. I've tried every kind of LG drivers but the problem's remaining.
2.Another problem is that when i try to use fastboot a "Failed" message is displayed for any offastboot commands. It's important to mention that my device it's recognized by laptop in fastboot mode.
3. Is there any kind of custom bootloader for this device to be installed?
I'd appreciate any of your help! Thank you in advance.

[Completed] T-Mobile lg v20 becomes un-visible when put into bootloader mode.

I can't add any comments on XDA forum where this wuestion belongs because I don't have 10 or more comments posted instructions other than programming and ROMs. however I did post it on the XDA assist forum but i was sent to check out a forum that had nothing to do with my problem. I have the correct drivers I have everything I need to have and as soon as I put my phone into the bootloader mode for some reason the computer cannot recognize it anymore. on the command prompt I type in ADB devices and nothing shows up however, before I put my phone into bootloader mode when I type in ADB devices my phone shows up. apparently this is a phenomenon that only happens to 3% of the people that try to flash this device. I'm not the only one apparently.
