ADB not seeing N7...

Yea. That.
Drivers seem good:

I can get into it from the computer.
I've tried different cables.
I've tried every USB port on my computer.
I can unplug the cable from the N7 and go directly into my N4, adb devices it, good to go.
I've noticed that, on my N4, I plug it in and I can get into it through Windows Explorer AND it shows up on ADB. On the N7, if USB Debugging is checked, I can't get into it through Explorer or ADB. If I uncheck it USB Debugging, Windoze does its little unplug noise, then the plug in noise and I can get into it. Is this a 4.3 thing?
Has anyone else had this happen? Is this a bug or am I the bug?
Any help greatly appreciated. Thanks!!

I don't have an N7 2013 (thinking about getting one though ) but passing on something a friend told me about her older N7 model: it didn't allow ADB while MTP was enabled. So you might try disabling that and seeing if it helps.

Maybe you have some permission problem and need to run the shell as administrator. It looks like the tablet was recognized from a driver standpoint.

Are you sure that's the right driver? It says Android Phone/Google Nexus ADB Interface.
Seems like you have the drivers installed for your N4 but not your N7.

Yours says something different? Mine says Android Phone and I don't think I've seen it say anything else, whether phone or tablet were connected.

I'm having the EXACT same problem and it's driving me nuts, my Device Manager says Google Nexus ADB Interface
EDIT: Solved it, go to settings > Storage > click the menu on the top right and select USB connections > Select PTP instead of MTP.

If you want to get it working with MTP and USB debugging enabled see this post:

I'd just like to throw in that I was having the same issues with ADB and the only time I got it to work was after I disabled MTP/PTP on the phone. Im sure there are better fixes in this thread but thats my two cents.

After updating to the latest driver version 8.0 it should say "Android Composite ADB Interface".

I'm having the same problem and it's driving me crazy!!! This is funny longest I've EVER went without rooting, assuming root was available for that particular device. I'm gonna try disabling both MTP and PTP, like mentioned earlier.

LG-G3 - USB Debugging not working Windows 10

I purchased an LG-G3. Performed an OTA update to latest: 47A. I connected to my Windows 10 box, enabled debugging, worked fine.
I downgraded using TOT method to 10B. The device is now running 4.4. Reconnected device to Windows 10 box, enabled USB debugging, does not work.
The device only shows up in device manage as a portable device
I have tried the sticky on this forum, unfortunately it does not apply as I do not have any of the items listed to remove
I have uninstalled all LG Driver/LG Verizon Driver/Google driver etc.
I have used USBDeview to remove anything named LG/ADB/Google
I have rebooted my machine, double checked the USB list with USBDeview
I have enabled/disabled/revoked USB Debugging, switched between MTP/PTP, rebooted phone
I feel like every time I google the problem a different way, I end up back at the Google USB driver download page or the LG Verizon driver download page
I would appreciate a fresh set of brains, I have a feeling I am now tunnel visioned and won't ever get out, please help ;0 I never get that prompt on the phone to allow the computer access to the phone, is that permission still on the PC is some fashion and needs to be revoked?

I ran a system update and the phone downloaded ~200mb file, applied and rebooted. Looks like that was 35B bootstack and now the phone does enable USB Debugging. Unfortunately if I take the phone back to stock USB Debugging still does not work
I also connected the fresh stock phone to another Windows 10 machine with the LG G3 Verizon Drivers installed and could not get USB Debugging to enable...

Cmd as admin, cd *adb path* , adb devices and an authorization should appear on your phone, usually works with me.

Appreciate the suggestion, tried that and adb devices command just reports no devices connected and no prompt on the phone

The cmd part as admin is very important, dunno why but it wouldn't recognize my phone unless cmd was started like that.

Where are the "Three dots" to change USB mode?

My phone don't show me the USB Connected/Charging notification anymore.
So I can't change it to MTP mode. It just charge when conneted to the PC USB port.
Googling around I've found thousands of tips like this:
MTP mode can be enabled/disabled in Settings > Storage > (overflow menu or 3 dots right top of the screen) > USB computer connection> tick the MTP

Bu I can't find these 3 dots ....

This may be something I've done because I was able to connect it as MTP before.
I just rooted it with Kingroot and deleted some unwanted apps (most by google).
How can I put these dots back?

It should pop up auto when you plug usb into pc, Rite in your notifications bar I had this issue on my G4 after debloating I could not get but charge only no MTP You may have debloated something needed. I also had this issue with my G3 and it was something to do with the pc install software but I cant quite remember how I did it if I cleared defaults...
Last resort is alway back up on Ext sd And retry stock firmware.... Kingroot is ok But IMO I never use it unless a last resort if you can root with stump or root.bats I recommend them first as they are normally pretty stable... Kingo and king have posed issues in the past or at least they have for me

If it's not coming up try going to developer options and selecting USB Configuration.
Also try toggling USB Debugging

Sorry all.
For some reason my cable was not data transfer capable.
Change cable solved the problem.
mea culpa!

Question Connecting Problem

It might not say the same thing if you don't have this set as the default USB option, which you can find and change if necessary if you use the search field at the top of the Android Settings for USB. It's the last option in this screenshot "USB Preferences":

USB Preferences look like this (when you're connected to the PC). What I have selected isn't the default - I had already changed mine:

Lastly, if necessary, have you tried rebooting the phone? Tried rebooting the PC? Tried a different USB port and USB cable?

Sounds like the ol' driver issue rearing its ugly head again. Tons of resources and just as many supposed solutions. One of them will work. Windows 11?

It's the driver. There are a few fixes out there but they are at least a couple of years old. But I believe they still work even though they were for Windows 10. If I recall it was a device manager thing and you needed to install a driver from the system or a delete the driver that is causing the issue and reinstall it. Here's an old thread but you can search for Win 10 Pixel and come up with a bunch of possible solutions. Good luck let us know if you can fix it and how or if you still need help.
[GUIDE] Fix MTP driver installation on Windows 10
Hi guys and girls... I just recieved my new phone a few days ago. Plugged it into an old Windows 7 x64 laptop and Windows instantly updated the driver. On a 2016 Dell E7450 Windows 10 x64 laptop... It didn't. Tried the Google USB drver package...

Question USB tethering

Any way to disable Samsung's 'cable detection' feature? USB tethering doesn't work because device doesn't recognize cable. I'm using original one and tried new and older cables also. I've had similar problems with another Samsung devices before and it's pretty annoying. WIFI is too slow and bluetooth even slower compared to USB so I don't like using them. Device just keeps telling use original cable and starts charging slowly.
Also the usb c port is cleaned, tried restarting device several times, tried all usb ports of my pc. I'm using Windows 10 pro. All drivers are updated and I have newest Samsung drivers.

Turn on Developer options and try setting it up there. No blocked or disabled Samsung system apps, right?

Tried that but it doesn't work. Also Windows is saying it can't recognize usb-device. I have disabled YouTube only because I use another app for that.

Hit take no action in the Windows connect popup*. Then go to Disk Management and punch scan for new devices. Access the drive in that window and do the transfers there. Command line can also be used to access Disk Management etc.
Try rolling back or updating the driver. Installing the latest version of SmartSwitch on Windows should load the correct driver.
*you must authorize the connection first on the Android via a popup window that should appear after being connected.

Not working. Reinstalled all usb drivers including Samsung ones. Smartswitch is not working because Windows can't recognize this device at all. Maybe I just reinstall Windows some day and try if it works then. Thanks for the help.

You're welcome.
Try another port and cable.
Reboot, always reboot Windows.
Check Event Viewer for error messages.
For Windows to recognize the device you sometimes need to use the scan for new devices command in Disk Management. The solution is likely simple and right in front of you.
Play with it... fun times.
