Nexus 5 (kitkat 4.4) Won't Authorize My Windows 8 Computer

March 12, 2024 Post a Comment

I'm trying to do some app development for Android with Eclipse and my Nexus 5. However, after the first time loading MyFirstApp from Eclipse, I can't seem to get the authorization

Solution 1:

Here's my solution
1. I re-download the latest ADT bundle
2. uninstall the old driver in "My Computer" -> "Device Manager" (delete the old driver also)
3. Right click on "Nexus 5" and update the driver using the one under "[New ADT Path]/sdk/extra/google/usb_driver"
4. Turn on debug mode (click on KRT16M multi-times)
5. Deploy my first app . And a popup on device appears. Click "Yes" to accept the key.

Good luck!

Solution 2:

Have you tried updating both the SDK and ADT ? Support for Kitkat is provided in the latests ADT

Solution 3:

For me a tutorial provided by AndroidGeeks helped me fix the connection issues to my Windows (7) PC.

"Make sure to enable the USB Debugging for your Google Nexus 5 from the Developer Options first.

Open Settings, then About Phone.
Tap the Build Number seven times to unlock Developer Options.

Now you can continue to the tutorial. How to install Google Nexus 5 USB / ADB / Fasboot / Bootloader drivers:

Download the Nexus 5 Drivers from here.
Extract the zip contents and place all files in a single folder on your desktop.
Connect your device to your computer.
Launch the Device Manager on your PC.
Now you should see the Nexus 5 listed in the hardware list.
Right-click the ‘Nexus 5′ line and then click on Update Driver Software.
Next, click the ‘browse my computer’ option.
In the new window click on ‘Browse…’ button.
Go to folder unzipped at step 2. Select the folder where you extract the USB Drivers. Click Next. - make sure to tick the subfolder box too.
Now, the Windows installer will search for Nexus 5 drivers, click Install when asked for permission.
Wait for the process to complete and then check the Device Manager list to confirm that the installation was successful.

Also, you should launch the device in Bootloader Mode to check and see if the device is connected by your computer. If not, then you should stay in Bootloader Mode menu and then repeat the entire tutorial listed above. Eventually, the Google Nexus 5 will be recognized by your PC."

Solution 4:

After implementing Nevin Chen's steps above without success, I ended up upgrading my system to Windows 8.1 for unrelated reasons. Out of curiosity I tried usb debugging again, and it worked the first time without problems. It has continued to work since.

I can only suspect that the problem was a system setting that was installed with an incorrect driver that only a system restore or upgrade would end up rewriting. Trying to uninstall the drivers from the device manager seemed not to help the problem.

I would be curious to know if anybody else has solved this problem with a system restore or upgrade.

Solution 5:

On Windows 7, I tried the instructions in the following link: https://developer.android.com/tools/extras/oem-usb.html#InstallingDriver

I didn't get anywhere after several attempts with restarts of both the computer & device, and I tried multiple USB ports. I also switched from Nova Launcher to the stock launcher with no signs of improvement.

In the end, I changed usb cables and it worked!

The first cable was from a Samsung Galaxy S4 and had a noise reduction choke that was not present on the stock Nexus 5 usb cable.
