ADB not recognising Nexus 4 under Windows 7

Question

I\'m running on Windows 7, and I\'ve updated all the drivers as it says on the Android developer website regarding using hardware devices. However, Eclipse is still not reco

Answer 1

I have 2 Nexus 4 devices. One was connecting to ADB without any problems, the second one never showed up when I used the adb devices command. An additional symptom was, that the second phone did not show up as a portable device in Windows Explorer when the phone was set to Media mode.

At some point I found that a temporary solution for the second Nexus was to switch it to PTP mode. Then it was found by the adb devices command. The weired thing was that the first phone worked in both modes all the time!

Finally I found this solution that now allows me to connect both phones in both modes:

• set USB mode of the phone to MTP (Media)
  Using PC device manager uninstall the device ->Android Device ->Android ADB Interface
  Make sure to check the box "Delete the driver software"!

• then set the USB mode of the phone to PTP (Camera)
  Using PC device manager uninstall the device ->Portable Devies ->Nexus 4

• Then unplug the USB and plug it back in (ensuring that its set to MTP (Media) and I found that the device was correctly registered in Device manager as a ->Portable Devies ->Nexus 4

If you have a similar problem to connect your Nexus to ADB then I recommend to first switch it to PTP mode. If your problem vanishes with that step, I recommend to go through the additional steps listed above as MTP will probably be the mode you will want to set your phone to most of the time.

Answer 2

(Windows 7) My solution to this was to find the device in Device Manager, uninstall the existing driver and install a new one from the android folder in your user account using the include subdirectories option.

All the best.
