[Q] "adb devices" command not listing my Nexus 7 (2013) !

When I try to run the "adb devices" command in the cmd prompt, its is just saying "List of devices attached", but the device Nexus 7 (2013) itself is not been listed. I am able to Kill and start the server. "adb reboot" command not working.
I checked the Device manger; It is listing the device as "Google Nexus ADB Interface" !
Also the "USB Debugging" is checked along with "MTP Device"
What could be the problem?? Any issue with drivers. I have already downloaded the adb and fastboot tools in the drive and running the cmd prompt from that path.

It's driver related, install these, then reboot the PC, then with the device plugged in, delete the Google Nexus ADB Interface from within device manager, delete the driver from system if prompted, and leaving the device plugged in, reboot the device, it should redetect the device properly, wait for it to boot up all the way, then unplug the device and plug it back in, and test, you will want to do this for every mode combination, as per my post found here: http://forum.xda-developers.com/showthread.php?p=50253887#post50253887
The important part is making sure the device is plugged into your PC and set to the mtp/ptp/debug mode you want detected when you reboot the device after deleting the driver from device manager.

Thank you for helping out. I found what was wrong. The drivers were ok. I had ticked the MTP device option earlier. When I ticked the Camera (PTP) instead, the ADB commands started working. I even rooted and installed custom recovery through adb interface.
Thank u once again.

You're welcome, fwiw, if you follow my suggestions, you can make it so adb works in ptp and mtp, but if it's not important to you, then it's not dire.

Computer finding G4 through ADB

Has anyone gotten their computer find their G4 through cmd (adb devices). I cant get the adb message on my phone to allow access to my computer. I turned on and off usb debugging several times but i still don't see the message on my phone to allow access. I let me computer download the drivers when plugging up my G4 as well as allowing the install of PC drivers.

yes, working great for me. Do u have updated and right drivers? u find tread here with right drivers..
Sent from my unlocked and rooted LG-H815

I was having the same problem..
You need to install the LG Drivers and then your phone will connect via adb..you will be asked on your phone to allow the port connection after installing the proper LG drivers. Verify and you will be good to go..
I used these ones below in the attatchment or you can grab them from.....
http://www.theandroidsoul.com/download-lg-g4-driver-for-windows-and-mac-mtp-adb-download-mode-77723/

I think I found the issue. I had Note 3, 4, Nexus 6, S6 edge, and G4 all still on my computer in the device manager. I uninstalled all of them plus I uninstalled the adb driver in device manager. Plugged my G4 back in and ran the PC driver update via G4 and it worked. I can now see my G4. Don't know if I had to do all that to get it working but hey it worked for me.

I was having issues with this myself and didn't find a solution. I found out that I was having better luck switching it to Camera PTP from the notification dropdown. Sometimes I have to toggle to MTP back to PTP, The dev notifcation should appear when it is actually connected.
1. PTP
(1a. switch to MTP back to PTP if it doesn't work)
2. 'adb kill-server'
3. 'adb devices'
-If you see your device, you can try to 'adb connect **IP**' but it will most likely say it was unable to connect
4. give it your adb commands you want
It's the only way I've been able to get adb, hope this helps!

I was having this issue also. After install win10 then adb connection to my LG G4 (h818) was not detected. Back to android.com, it said that if general USB driver doesn't work then we must find OEM driver to the producer web. LG ADB Driver was about 17MB. After installed the driver then it was immediately detected. Thank God, finally.

I have silly problem. I bought used G4 LG from someone found in online forum. Checked all series on phone (sticker), on software "about phone" all showing LG H815 software version H81510H, but by adb ( linux machine ) showed H812xxxxxx .... set on developer option debugging the command "adb reboot bootloader" just send device into android boot ( device boot ). I wish to unlock the bootloader and put CM. Hard button option > pushing vol up + power button simultaneously did nothing, vol up + power button then > connect to PC via usb, did nothing ( just send phone to device boot ) ..... I have no windows machine

[Unrooting] fastboot does not detect OP3, while adb does

For the past few days I've been trying to pass SafetyNet with root and after I failed, I tried to unroot my phone as passing SafetyNet is more important to me than having root. In the processing of doing so, I messed up some things on my device. I flashed all uninstalllers of SuperSU, Xposed, Magisk and other stuff I flashed through TWRP and deleted all SU files in bin and xbin. It removed root but I still wasn't able to pass safety net. I then messed up somehow and removed my TWRP and now when I try to access recovery it simply boots up my phone. I decided it would be the best to simply reset my phone using fastboot and adb (maybe even lock the bootloader again?). Fastboot however, cannot detect my device while abd can (not in the bootloader menu though). I have searched arround on the internet, have installed tons of drivers, reinstalled the SDK + Android Studio,... but I can't seem to get it work. When my device is booted up, it shows in Device Manager as "ONEPLUS A3003" and when in fastboot mode, it shows as "Android Bootloader Interface". Updating the drivers doesn't help. Would love if someone was able to help me out here!

The problem is the last update windows 10. You need to connect your phone in fastboot mode to your PC. Then go to the Device Manager, find there KEDACOM USB Device, clicked and appears in the ANDROID BOOTLOADER INTERFACE. Click on it right mouse button, put the Update Driver Software, then search for drivers on the computer, then select DRIVERS FROM THE LIST and select FASTBOOT INTERFACE (USB GOOGLE ID).

Got it working with your help! Had to completely remove the drivers first and than put my PC into flight mode though, because Windows 10 would keep reinstalling the drivers. Thanks for your help!

Pixel XL (Verizon) Not Being Recognized via "ADB Devices" command on Windows 7.

Pixel XL (Verizon) Not Being Recognized via "ADB Devices" command on Windows 7.
So I got my 128gb pixel xl from Verizon today. It's still 7.1.0 (Build NDE63P) so I want to unlock the bootloader asap. I was able to get the phone booted up and mostly set up without taking the OTA update (I pulled sim card before booting the phone for the first time, and I skipped the wifi setup).
I intended to follow the instructions here to use dePixel8 to unlock the bootloader. I got USB debugging enabled on my phone, and ABD/Fastboot installed on my computer (Windows 7 laptop). The problem is the phone doesn't come up in the list when I use the "adb devices" command from the command prompt within the SDK folder. Looking at the device manager, it appears my laptop is automatically installing the "Google Nexus ADB Interface" driver for the phone, is this not the correct driver? I downloaded the USB drivers from here and tried pointing the Device Manager at them to force a driver update, but the device manager tells me the drivers are already up to date.
Can someone please explain to me how to get my computer (Windows 7) to recognize my phone via ADB so I can push dePixel8 and unlock the bootloader? I feel like I'm so close to being able to unlock the bootloader, but my phone not being recognized via ADB is driving me freaking crazy.
Thanks!
EDITED TO ADD: If I turn off USB debugging, and just put the phone in File Transfer mode when connecting via USB, it never shows up in Windows Explorer as any kind of storage device, which would make me think its a problem with the driver, right?

That link has the wrong Fastboot ADB version. Use this one

Thanks for the prompt reply. I'm currently uninstalling Android Studio and SDK I downloaded, and will install the one you linked.
I think this is still a problem related to the driver Windows 7 is automatically installing for my phone. If I turn off USB debugging, and just put the phone in File Transfer mode when connecting via USB, it never shows up in Windows Explorer as any kind of storage device, which would make me think its a problem with the driver, right?

Hello, I followed your mentioned steps but in my drivers its showing "Samsung Android Device" is that okay for my asus zenfone max pro m1 device? Or there is one portable device option, is that it?

Hi guys, specially opened an account because of this issue. I am unable to run the fastboot devices command even after following all the aforementioned steps. Phone screen turns black and a message appears on the top left stating "press any key to shutdown", while the fastboot devices command gives a "??????? fastboot" response on my PC. PLEASE HELP!

After I completed all the steps, my phone showed on screen "press any key to shutdown" and even in device manager it shows android ADB interface as hidden. Help please. Rebooting again to fastboot mode doesn't help because it shows the same screen "press any key to shutdown" on reconnecting with PC.

Well i learned this from somewhere but actually you need to turn off the secure boot in your PC from the BIOS. That's what helped me do it

Well you know how there's a BIOS in your PC which contains the basic commands required to run a computer. There is a setting called secure boot inside your BIOS. You need to turn it off and then install fastboot tools. To open the BIOS, repeatedly press F10 or F8 on your computer while it is opening. This is how it worked for me atleast
