[Q] Can't ADB in bootloader mode?

I can ADB/fastboot my device most of the time.
But when booting into Bootloader mode, I suddenly can't ADB into it?
The driver appears to be loaded up in my Win7x64 computer. Says it's the Motorola ADB device. And I can open my files on the phone. But ADB just doesn't see the phone for some reason. Any ideas?

Bootloader is fastboot.
Code:
fastboot devices

Does fastboot work properly?

Windows 10 Home on host computer, and ADB tools installed.
USB debug mode on and host computer allowed.
USB PTP mode.
LG Unified Driver installed.
I opened command prompt, locate adb platform-tools. Ran the following commands
Code:
adb reboot bootloader.
The phone rebooted to bootloader.
On the bootloader mode on the phone, I typed
Code:
fastboot reboot
The phone rebooted properly
Does it work right?
Currently the phone is not ready to unlock bootloader until there's no problem, especially speaker problem, found.

Device not listed in fastboot

My device is not listed in fastboot devices. However it can be seen in adb mode. I have tried doing:-
1)entering in fasboot manually as well as via "adb reboot bootloader" command.
2)Updating drivers or installing them manually(tried several of them, but none works)
List of drivers that i have tried
1.Universal adb driver by koushik dutta
2.Samsung adb driver
3.Google sdk drivers
4. Installing some random unsigned driver(Last method done)
Please help me i want to revert back to miui by flashing it clean via Flash tool but device isnt detected what to do?

Yes..i do use windows 10....the solution that worked for me this time is to delete every driver of my phone present in my pc and connecting it....by every driver i mean each and every one(inclusive of adb and fastboot and also usb drivers)...so pc installs a driver by itself and surprisingly it works

Download Adb and fastboot.rar from google.
Extract it to desktop.
Then install Miflash , downloaded from google.
And for fastboot watch video from youtube.
If you are again unable to found or for any type of help.
I'll provide you the files with the video.

and you won't be needing drivers. and your device would be listed.

My phone is not recognized in ADB console while running fastboot mode

I wanted to install a custom rom for my moto g4 and I just have problems with installing twrp. I downloaded twrp img and adb tools, then connected my phone to the pc in debug mode. In the adb console, the phone is displayed, but when I put the phone in the fastboot mode, it is not recognized.

that's cos there's separate program (e.g. fastboot) for interfacing with bootloader (c.f. Android Debug Bridge for interacting with recovery or Android).

ADB driver in booted vs fastboot status

Windows 7...
Seems I can have either ADB drivers installed for when the phone is booted or when the phone is in fastboot mode, but not both. I have fastboot ADB drivers installed now as I need them the most; it's easy to reboot the phone into bootloader. Am I stuck with one or the other? If I install the ADB driver when the phone is booted I lose the fastboot drivers. TIA.

I don't think you lose the drivers... you just can't see the device using ADB when in fastboot mode and vice versa.

It's more like I have to install from a different driver package for booted vs fastboot condition. Both work, I just have to redo the driver install depending on the state of the phone. Seems odd.

Hey, I've been having a lot of trouble getting fastboot to work properly. I can get adb commands to work with my phone on but fastboot commands in fastboot mode don't work at all. I've been at this for about an hour.
I sort of get what you mean when you're saying you need to install separate drivers each time you want to switch between having adb and fastboot work. How exactly did you install "fastboot" drivers and how would I go around doing that? Help would really be appreciated!
