I have tried everything but I can't get my phone to appear in adb devices when in bootloader mode. It appears in adb devices when I am in the OS but when I type adb reboot bootloader and type fastboot oem lock it just says waiting for device. I have installed drivers from kies and the Google USB driver. No adb or unknown devices appear in device manager when in bootloader instead it comes under USB devices. I am running latest firmware and have removed root.

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
I went through the motorola site unlock bootloader process. Installed the Android Studio and the Motorola device manager. ADB saw my device and was able to unlock device. With the phone in normal mode and developer options set ADB sees the device. But when I go back into fastboot adb no longer sees the device.
Windows10 still sees the phone (mot composite ADB interface) in device manager but ADB shows no devices listed.
I'm just trying to get the phone rooted.
Resolved: Was using WinDroid under assumption that it needed to be in fastboot.
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.
I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!
hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device
Solved!

I'm dumbfounded. I have unlocked bootloaders and rooted for years. Just got my OP8P.
I also have a new Microsoft Surface Pro with Windows 10.
I installed ADB, installed Fastboot.
Unlocked developer options and turned on USB Debugging and Developer Unlock.
Windows device manager shows ADB INTERFACE for the my device in device manager.
I can open can open Power Shell and/or the CMD prompt. I've done both.
I can type adb devices in the command prompt and I CAN see my device.
I can reboot it fastboot from the CMD prompt so I KNOW Wndows sees my phone.
BUT ONCE I'M IN FASTBOOT, the problem starts.
Fastboot does NOT see my device. Commands return the words "Waiting for Device..."
I BELIEVE the issue is with the drivers. When I boot into Fastboot, my device location changes in Device Manager from USB>ADB Interface to Portable Devices>Android.
The Android Device icon has a yellow triangle with an exclamation mark. It's says the driver for this device is not installed. But everything was working fine and the drivers were fine while the device was powered up normally.
If I try to manually install the driver it fails and says "cannot update drivers for your Android".
What heck is going on? What did I do wrong?
I've uninstall and reinstalled the drivers direct from Oneplus. I've uninstall and reinstalled the drivers direct from Google. 'I ve uninstall and reinstalled the drivers direct from Windows.
Why can't device and drivers be recognized in Fastboot. And why can't I update the drivers for the "Android" device?
