Nexus 7 (WiFi) Android 4.3 - USB Debugging disabled? - Nexus 7 Q&A, Help & Troubleshooting

I enabled USB Debugging Mode and Camera (PTP) but Nexus 7 (WiFi) doesn't display, on notifications, the debug icon. When doing adb devices, no devices are attached.
Build Number
JWR667
Android version:
4.3
Any ideas about this?

And what does device manager on computer show?

2 Nexus 4 devices behave differently in USB (MTP/PTP vs Android ADB interface)

I have 2 Nexus devices, the first one had some loose part inside and I ordered a replacement.
All was good and fine for the first one on USB connection. Win 7 x64 can recognise the old Nexus 4 in MTP, PTP, with or without USB debugging enabled. Then I have the LG USB driver installed and so I can backup my apps, game saves etc using ADB commands.
The replacement unit arrived yesterday, connected with the same USB cable. However, this time, it failed to recognise the new Nexus 4 in MTP or PTP mode, checked windows device manager, only showed up as "Android ADB Interface". If I enable USB debugging, it becomes "Android Composite ADB Interface", PTP mode managed to show up. But when switch to MTP mode, it doesn't show up.
How can I fix this??
Thanks.
do you have a non working mtp device driver in devices when plugged in?
you might have to put the device id in the mtp inf file, i had to with xp to get mtp working when in debugging mode.

when plugged in, it just show "Android ADB Interface" when USB debugging is disabled, same description for both MTP and PTP. Just different hardware ID.
MTP with USB debugging disabled: USB\VID_18D1&PID_4EE1&REV_0228
PTP with USB debugging disabled: USB\VID_18D1&PID_4EE5&REV_0228
MTP with USB debugging enabled: USB\VID_18D1&PID_4EE2&REV_0228
PTP with USB debugging enabled (Android Composite ADB Interface): USB\VID_18D1&PID_4EE6&REV_0228&MI_01
PTP with USB debugging enabled (PTP Camera portable device): USB\VID_18D1&PID_4EE6&REV_0228&MI_00
Can anyone shed any lights? :crying:
Just want to emphasis that all works fine if I plug in the old Nexus device.
I suspect it would work if I format and reinstall my Windows, but don't want to go down that route unless there is no other method.
open up windows/inf/wpdmtp.inf and find these lines near the top of the file...
[Generic.NTx86]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MT
[Generic.NTamd64]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MT
i ammended mine like so, but mine wasn't working in debugging mode, so adjust yours accordingly...
[Generic.NTx86]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
[Generic.NTamd64]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
then i updated the mtp driver, using automatic option.
hope it helps.
I had the exact same issue with my original and new RMA N4.
This thread worked perfectly for me. Now both show up as MTP and PTP as the original did:

Android Studio not picking up usb device

I have verified that the device is recognized on my mac:
View attachment 2034718
but in android studio the device is not recognized:
View attachment 2034719
this is especially strange because i just successfully recognized my galaxy tab, but now my galaxy s3 won't recognize.
turns out on the galaxy s3, you have to turn on usb debugging in settings->developer options.

[Q] Nexus 10 and Windows 7 x64 drivers

Hello there!
Yesterday I updated my N10 to 4.4.2 and had to endure an ordeal just in order to get ADB working (please note that this happened both in 4.3 and 4.4.2).
Below you'll find a comprehensive list of all the settings combinations I tried in the N10 until I found one that got ADB working.
However, there's NO combination in which MTP works, at least for me.
Windows 7 x64 (N), with Media Pack installed. Rebooted serveral times.
Drivers installed using option #1 in Nexus Root Toolkit. Fastboot drivers work ok.
Any idea on how to get MTP working? Thanks in advance.

101. USB debugging on. MTP off. PTP on.

- Device Manager: Two items.
"@wpd_ci.dll -> MTP USB device (with a yellow ! in the icon)"
"SAMSUNG Android Phone -> Google Nexus ADB Interface"
- ADB Device detected.
Edit: OK, after using method #3 in the Nexus Root Toolkit I now have ADB working also in the 100 configuration. No dice on the MTP file transfer, 'though.
Go to device manager and select "show hidden devices". Then delete everything that has to do with tour Nexus 10. This will also delete your adb drivers. Then plug it in the computer with a different cable. Or search the internet for drivers.. Toolkits arent fail proof.. Hope this helps.

I had the same problem (Windows 10), and after having tried a lot of different suggested solutions, I did what mrgnex recommended, and it worked! Thank you so much!

Can't see my phone in Windows explorer when USB debugging ON

Hi.
I'm running Android 4.4.2 on my Nexus 4 but as it's rooted and I use Xposed framework, I can use OTA to install 4.4.3
I'm following this tuto : http://nexus5.wonderhowto.com/how-t...ndroid-4-4-3-without-losing-any-data-0155334/
which should work for any Nexus device but I can't see my phone in Windows explorer when USB debugging option is set to ON.
What's wrong ?
Thanks.
EDIT : switching from MTP to PTP mode did the trick.

Solved: Nexus 4 - MTP not found - Windows 7

Hi,
My Nexus 4 is set to MTP Mode and Device Manager shows the following:
USB\Vid_18D1&Pid_4EE1&Rev_0228
USB\Vid_18D1&Pid_4EE1
The Nexus 4 shows up with triangle and i can´t transfer files.
How can i fix it?
Problem solved!
Nexus 4 doesn´t work at USB 3.0 port.
Connected it to USB 2.0 port and it works now.
