Android Studio no longer recognizes LG G Stylo

I need to know how to make Windows 7 forget it ever connected to my LG G Stylo phone. I have three devices that I use in Android Studio development. For some reason, this one is no longer being detected by the ADB. Something has happened to make it no longer show up, because it did a couple of weeks ago.
AS's ADB will detect my other two devices, and this device shows up in the in the ADB on another computer. I have tediously gone through the registry and removed everything referencing the Stylo, but it still will not show up in AS's ADB.
Thanks for the help!

To start, I have just purchased the LG Stylo 3 plus and ran right into this situation. TO repeat the basics you need
With Android Studio shut down...
Turn on Developer options (tap 7 times on build number in settings
(Settings>System>About Phone>Build Number
Turn on USB Debugging in Developer Options
(optionally) check on the type of USB connection, MTP or PTP should
work
(Optionally) Because I did it, also do a revoke USB tap.
Here was the key for me. I needed to install the LG USB Windows Drivers for my Windows 7 (I'll try 10 tonight and update). Go to this page
LG Drivers and firmware
and either type in model number or browse to find device. LG has a nice interface to install the Windows Drivers. I recommend the Support tool to verify the device as the up to date drivers as well. Start Android Studio and to test I just started the app in debug mode and went through the process of setting up ADB for using the new;y connected device.

Developer options" has to be ON in order to make AS see the device
If even though device manager you can't saw the device, Windows couldn't find drivers.Maybe the drivers are hidden on the device otherwise download it and install it.
If that doesn't work:
Shut down
Hit F8 (or whatever gets to startup options screen on your computer)
Disable Driver Signature Enforcement.
Run driver

Android Studio 2.1.1: "no usb devices or running emulators detected"

Suddenly my Android Studio stopped detecting all my devices, none of them is working. It happen from one execution to another. I've changed a few lines of code (1 min maybe?), hit run (instant run) and then I missed all my devices.
I'm using a Mac and as devices: Nexus 5x, Galaxy s6 and Oneplus One. What can be happening? I've checked previous questions here and tried all this:
Run configurations: no matter if I chose usb device or show the window, it does not work.
Tools > Android > Enable ADB integration: didn't help
Command line adb devices does not detect any either.
I've revoked and granted again USB authorizations. Still not working.
I've tried other apps I have, none work.
Restarted phones
Restarted android studio
Restarted computer
(Note: if I start an emulator it works, but I'd prefer to use physical device since I have to scan real barcodes)
Thanks a lot in advance.

On Lollipop 5.1
Go to About Phone
Click 7 times on Build Number. Now Developer options are enabled
Go back and Click Developer options
Enable USB debugging under Debugging.

Well, I've fixed. The problem in case any faces the same was a Stetho (http://facebook.github.io/stetho/) tab in chrome, the one you open by typing: chrome://inspect/#devices not sure about the reason because it's been open for 2 days now, but it was the cause, once I closed it, it worked.
Found this unaccepted answer here: macbook adb cannot open interface That for sure should be accepted.
EDIT: I've been able to replicate the problem. It happens when you have the devices tab open and try to run a second app that has stetho configured.

It happens if your device drivers not installed Please do this.
In Case of PC
Right click my computer select manage select device manager from left panel if your phone drivers not installed there will be yellow alert on driver right click on it select update driver software then select search automatically for update driver software.
Other
Please install the missing drivers of your phone.

I had the same problem . What I've done to solve it going to Setting >> Additional Setting >> Developer Option
Now select:
Developer option on
USB debugging on
Install via USB on
USB setting security on
Verify apps over USB

OK, what finally worked for me was to go into Settings\Developer options\Select USB Configuration and change it to PTP or MIDI....either one of those worked for me and all of the sudden my phone showed up and I was able to see and run my test app on my android phone.

This woorked for me
Go To Settings
Developer Options
Enable USB Debugging
Enable Verify Apps over USB
Select USB Configuration: Choose MIDI
I hope it also works for you

LG G3 device not recognized by Eclipse on Windows

I recently bought LG G3 and I have enabled debugging mode but Eclipse is still not recognizing it, back when I used the Galaxy S3 for development I had to install Samsung Kies. The G3 drivers are installed and I can see it in My Computer, do I need something like the Kies but for the LG? If so can someone please post a link for that?

See update below
I found the answer that worked for me.
When you plug in the phone, bring down the status shade, pick the USB item ("USB connected") then, from there, pick "Internet connection" -- I chose Ethernet, but I'm not sure the choice matters on the dialog that pops up..
This enables USB debugging to become active; leaving it on Charging, MTP, or PTP does not work.
Once you do this, you can follow #Siddharth's steps to setting the ADB drivers, if needed. (You may need to use the actual LG drivers and not the Google drivers, but once I got this far, it was just like any other phone.)
Caveat
For me, even after going through this once, I still get the "installer" first and then have got go in and choose the "Internet connection" again. But, at least it works.
Update 10 Dec 2014
A recent firmware update has, indeed, removed the "Internet connection" as an option. Instead, PTP now works. I still get the "Connected as an installer" notification every time I plug in the phone and have to click on the notification then click on "Camera (PTP)" -- or wait about a minute. It's slightly better than what It was.
Also note: When this change occurred I had to install the drivers again for the phone, since it comes up as a different type of device when "Camera (PTP)" is chosen than when I used the "Internet connection" option.

For me, this has solved the problem: simply go to LG's website, http://www.lg.com/us/support/software-manuals, select the model (I have selected 'D850') and go to Software Updates tab where you can download the driver. I have installed it and then Eclipse recognized my device. I'm working on Windows 8.1, by the way.

After a lot of searching and trying all solutions still I couldn't connect my LG G3 to eclipse on mac. Finally I find this solution, it works for me hope for you works too:
Install LG USB driver for mac
Go and enable developer mode in your G3 (Setting->About phone (in General Tab)--> Software information --> Tap 8 times on Build Number) then you will see the message which says the Developer option is enabled
In this step you expect that after connecting your mobile via USB cable, the Eclipse detect it
But for me it didn't happen
in this step you need to go (Setting--> Developer Options--> and turn off this option from above green (on/off) switch then again switch on this option from same place (If you don't do this step the "USB Debugging" mode will stay fray and you can not enable it)
In Developer Options menu scroll down until find the "USB Debugging" then tic it and enable it.
almost finished , you should back and configure running mode for your application and see the G3 in your connected usb devices

Try this solution :
Right click on My Computer --> Properties --> Device Manager
Right Click on your device --> Update driver software
Click on "Browse my computer for driver software"
Give path of your android sdk like "D:\Android_Sdk\sdk\extras\google\usb_driver" and tick "Include subfolders"
Click
Now repeat the steps till "Browse my computer for driver software".
Then click on "Let me pick form list of device drivers on my computer". Click on the first option and click next and then click yes. Drivers will be installed for your device.
Hope this helps.

Change the USB mode to PTP and you will get the RSA prompt.
Within the prompt, select allow it > ok and you are done.
This worked for me when I had the same problem on a Mac computer.

To contribute to possible solutions for this fix: I am using an LG G3 on a Mac.
In my case, ADB saw it as a device when I checked, and the Mac showed the device information in the System Information window, yet Eclipse did not see it. I also did not get the RSA confirmation pop-up when I connected the device through USB.
To fix, with my G3 connected, I selected the USB PC Connection (either from the navigation bar or through the settings) and changed it to be Send Images (PTP). Once this was on, I was given the RSA pop up and Eclipse recognized the phone in the Run Configurations window.

If you have this problem on Ubuntu; here is what I did to get it working:
Switch to PTP from MTP on the phone (this assumes you're connected via USB)
Disconnect the USB cable
Go to settings -> developer options and select revoke usb authorizations then ok
Make sure USB Debugging is checked
Reconnect the USB cable and your phone will say its connected as an installer; wait a minute or three and debugging mode should appear on the status bar (on the phone)
Open Eclipse and go to DDMS
Select "reset adb" in the dropdown if your phone isn't appearing yet

Working on Windows 7. All of the solutions from other sites didn't help (i.e. restarting adb and switching between MTP, PTP, Charing). In the end, I found this article (http://www.technobuzz.net/install-lg-g3-lg-drivers-windows-mac-usb-adb/), which contains links for the necessary drivers for the lg g3 (and some others I think). This did the trick and made the RSA key fingerprint dialog appear finally. After confirming, adb and eclipse recognize my device perfectly!

I had this buggy error with my LG Optimus L3 phone connecting to Win7/8 machines!
Cause: Device Driver was missing as it seemed at the end when I fixed it!
How to Fix:
Search through web (using Google) "LG < Your_Phone_Model Number > Drivers Download".(Ex.:- Go to About phone in your settings list > Model Number, for me it's LG-E400f)
Mostly the first few links are related to the required Device Driver download page.(Ex.:- for me I got the following link and for each device driver LG or most of the other vendors/manufactures have that kind of a Manuals and Drivers Page) Visit that page mentiioning about software update and drivers downloads.
Scroll down to the section of "Manuals and Software Update" and doing just the Step 1 was enough for me, which is "Install the USB DRIVERS "
Download it(for Mac or Windows) > Install It > Check Your Eclipse ADT > and it should be visible under Devices tab by now
Cheers!!!
Hope this helps to someone else to clearly get to the solution!

it seems that Eclipse shows the offline mode for lg G3 and some newer devices
and there is no way no use these devices for ADB debugging
there is a way
I am using windows 10
1- download this 11 MB file < http://dl2.uncox.com/android/upload/platform-tools-v22.zip>
2- then go to the directory that you installed the SDK
3- extract the zip file in to the platform-tools folder , override all files(click yes to all) be sure that Eclipse doesn't running
4- open Eclipse and select your android device that stands in devices tab at the right-top corner of your screen and then you can see the arrow near the screen- capture icon and you will find the reset-ADB. click on it ,after that your phone will ask you to allow android debugging for your device click on it
5- congratulations .now you can see that your device shown online
i hope this will help .sorry for my english

I also had a great deal of trouble when attempting to debug android applications on my shiny new LG G3. What ended up working for me was first installing the default google drivers onto the G3 and then following the process detailed by #lilbyrdie.
The process of installing the google usb drivers is very nicely gone through here.
However, with the most recently pushed android update to the G3 there are no longer the options for internet connection or charge only; but they seem to have fixed this defect forcing you to make this odd choice to enable debugging. The only options remaining are MTP and PTP, but if you pull down the notification drawer, choose the 'USB connected' notification (assuming the device is connected to your computer via USB of course) and from there click on 'Media sync (MTP)' even if it is already selected then debugging should be enabled.

Android can't update on the fly the developer mode. So, after turning on developer mode (and given you have the latest driver) switch the green button(under settings->general->developer options) to off and then back on. Then turn debug mode on (after that windows recognizes a new device) and you should be good to go.

In my solution for Windows 7 was helpful to update Android SDK Tools to latest version.

ADB Single/Composite values for LG G3 phones -
I found it was necessary to update (~userName/.android/)adb_usb.ini file with the line 0x1004:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2207
0x1004
In addition, I needed to add the following entry in (.../sdk/extras/google/usb_driver/)android_winusb.inf:
;
; Android WinUsb driver installation.
;
...
[Google.NTx86]
...
;LGE Android Phone
%SingleAdbInterface% = USB_Install, USB\VID_1004&PID_633E
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_00
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_01
[Google.NTamd64]
...
Oh, and set USB to PTP as well as turn-on USB debugging.
When you're all done with the file modifications and several passes at installing the drivers (ref. earlier posts), you can verify your phone is ready via the Device Manager. It will list your phone as "Android Device"->"Android Composite ADB Interface". I believe an earlier post explains setting up the drivers

Eclipse is not picking up my Android devices target API

I realize this has been asked before but none have been able to help me, I want to use my Nexus 7 with my pre-existing Android project but when I attempt to use it Eclipse doesn't pick up it's target.
-I've updated my related drivers.
-The Android composite ADB interface is up to date.
-It works on the device I was previously using (HTC Desire S).
UPDATE
It does not pick up the target when Iconnect it as PTP and MTP + in both it registers the state as offline.

the most common reasons for the device not showing up as a target.
1) "Eclipse needs to be restarted".
2) the driver for the device is not installed properly.
3) the target api/version code is not compatible
try
1) to plug the phone into a different usb port. (that sometimes refreshes the driver)
2) create a empty project that is compatible with your android version and see if it picks
up your device (if it does that means you have to update the targetSdk for your project).
if all fails restart eclipse a few times and keep your fingers crossed.

If you like playing around with your Android device (e.g. rooting or installing custom ROMs), then you probably are familiar with Android’s ‘USB debugging mode’. However, USB debugging mode is really intended only for developers and people who don’t know what they are doing may accidentally enable it and put their device at risk. This is why starting in Android 4.2 Jelly Bean, Google has hidden the ability to enable USB debugging mode. If you want to know how to enable USB debugging mode in Android 4.2 and higher, this guide will show you exactly how to do that.
The following steps work on all Android devices running Android 4.2 and higher. That includes Nexus 4, Nexus 10, Nexus 7, Galaxy Nexus, and any other device.
How to find and turn on USB debugging mode in Android 4.2 and higher
To see the option for USB debugging mode in Android 4.2 or higher, do the following:
Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
Now scroll to the bottom and tap “About phone” or “About tablet”.
At the “About” screen, scroll to the bottom and tap on “Build number” seven times.
Make sure you tap seven times. If you see a “You are now a developer!” message pop up, then you know you have done it correctly.
Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.
Conclusion
That was easy. The best part is you only have to do the tap-build-number-seven-times once. After you do it once, USB debugging has been unlocked and you can enable or disable at your leisure.
If you alrady done,

Android. Debugging on a real device (Nexus 7)

People, help please. Do not know what to do. Installed Android SDK, all as it should. Create the first application, the normal code, compilation errors does not. But to test this whole thing on the emulator - "hellish inferno."
I have an Asus Nexus 7 (tablets). How do I debug it? Eclipse and adb no means see it.
p.s. Yes, of course I brought the tablet to "developer" and check the "Debugging USB"
ps2. Yes, I put a USB into the computer.
p.s.3. Wood poses with SDK Manager (also tried to put the official website ASUS)

This appears to be answered here: Not seeing Nexus7 in Eclipse's Android Devices.
Specifically note the comment to the top rated answer where it suggests getting the driver directly from ASUS here.

cracked it after 2 hours...
download this usb driver:
http://dlcdnet.asus.com/pub/ASUS/EeePAD/nexus7/usb_driver_r06_windows.zip
2.go to the device manager , right click the nexus device and choose properties,
choose "hardware" and then choose update your driver , choose manualy and pick the folder
you opend the zip file to and press apply.
3.open your setting in nexus . go to : "about the device" , at the bottom of the page and press it 7 times .
4.open the developers menu and enable debug with usb.
5.finally press storage from the setting menu and click the menu that apears at the top left corner.
press the connect usb to the computer, choose the second option (PTP).
that should do the trick , they couldn't make it more simple than that...
