I just bought a Galaxy Nexus, now I got a problem, my ADB doesn't recognize it. The Point is when I connect it, it shows it as Storage-Device on my Computer but it isn't listed as an ADB Device.
When I connect my other Phone (HTC Desire HD) it recognize it without any problems.
Some information about the System and Config:
- I'm on Win7 Service Pack 1 64bit
- Galaxy Nexus is in debugging mode
- The Device isn't shown in ADB but Windows recognize it as Massstoragedevice
- Eclipse and Googlepack is updated to the newest Version
Check if you have installed this package in your ADB "Google USB Driver package, revision 4"; if not do it.
Another possible solution could be downloading the drivers from here: http://www.samsung.com/us/support/owners/product/SCH-I515MSAVZW
This appears to work for the Samsung GT-i9250 version too.
If you have previously installed the ADB Driver for the Nexus ("Google USB Driver package, revision 4"+) you may have to manually reinstall it.
The driver is located here:
android-sdk\extras\google\usb_driver
Simply follow your os (in Windows Device Manager -> Update driver -> Have Disc -> "Android ADB Interface"
Go to android-sdk/extras/google/usb_driver & replace android_winusb.inf with the one downloaded from https://github.com/gu1dry/android_winusb. This will add a bunch of devices, Galaxy Nexus included. Then point to that dir when installing a driver.
Make sure that you have installed the usb drivers for the phone too.
You can take a look at this guide about setting up devices for testing and see if you have missed any of the steps.
you may try this: go to settings>Applications>Development>USB debugging(check it if it's not )
try to do this - go to Phone SETTINGS, STORAGE, tap the menu (the three dots in top -right corner, select USB COMPUTER CONNECTION and in the menu select MEDIA DEVICE (MTP). This instantly connected the phone to the computer. Hope this will solve your problem!!!
The drivers for the US Galaxy Nexus (SCH-I515) do work with the European version (GT-I9250M), but you must use a USB 2.0 port. I spent a very frustrating hour trying to understand why the phone wasn't recognized before I tried a different port and everything worked. Only difference, the initial port was USB and the second USB 2.0.
Go to Root access in Settings->Devleopment options. Select APPs and ADB.
I had this problem with the new nexus 10, theses two articles helped me, perhaps obvious but...
Update drivers through SDK manager: http://developer.android.com/sdk/win-usb.html
Set up the device on various platforms: http://developer.android.com/tools/device.html
Hope this helps someone!
I just wasted a couple of hours reanimating my Galaxy Nexus.
I was able to access its data. Though, it did not show up as a correctly working adb device. Furthermore, in the device manager, the "Galaxy Nexus" was listet under "Other devices" and no valid driver was found.
I am not really sure what helped in the end BUT: Try wipe the authorized computers on the phone: Developer Options > Authorizations for USB-Debugging.
