I want to test my app on windows phone 8 device. But to deploy any app on a device, we need to developer unlock it. I tried doing it using Visual Studio 2013. But when I try doing it-
I get 2 errors-
1.Check date and time .It does not match
2.Check your Microsoft credentials and try again.
Please help. Have tried alot.
Thanx in advance
To unlock your device with using developer account, be sure your device connect a available network, and then retry it.

I wanted to get started with app development for windows phone 8.1. I own an up-to-date Lumia 630 device with Windows Phone 8.1 which I wanted to use as test device. Now, the problem is that i can't register this device as a test device. The registration tool which came with the sdk 8.1 always give me the 0x64 error code. I googled this problem but none of the solutions (including the ones here on stackoverflow) solved the problem for me. My phone has internet connection through wi-fi and is unlocked and up-to-date (tryed restarting and not using wi-fi). Also the windows background service is running (also tryed restarting it). An up-to-date windows 10 is running on the laptop with which I want to develop.
My microsoft account is not a developer account but from my understanding, i should still be able to use at least one device as test device without having to pay.
I also posted this question in the microsoft forum.
I appreciate any help.
I think your account must be associated with dev account.
Not sure what changed, but it appears this is now fixed. I am able to register multiple devices to my developer account again.
I am facing problem in deploying windows phone 8 app in the emulator. But each time I am going to deploy its showing the message like the figure. Can any one please help me how can I get rid off this disgusting message? I am using using VS Express 2012 with update for in Windows 8.1 Pro.
You need to hit the Retry button. If that succeeds then log off of the machine and then logon again.
Pressing retry will add you to the Hyper-V administrator security group. After this you have to sign out of your development machine and then log in again for changes to take effect , and then deploy app to the Emulator.
I have a problem , I can't fix this.
I deploy project with device (lumia 520) , but visual push notification: windows phone 8 phone was detected. But , my phone is really plug in my computer , and i can access phone's folder.
My phone didn't lockscreen.
Phone's driver has installed.
You can see in the picture:

I was restarted my phone for 10 times , but it's still connected.
Help me resolve this problem , thanks
Have you ever tried to deploy your app to an Windows Phone Emulator?
If your app succesfully deploying to Emulator, I can say your connection of your phone is having problem. But, if you can not deploy your app neither phone nor emulator, it could be about VS2012 or SDK.
So, I sugges you to remove your phone from your computer (Open Device Manager and remove your app (dont forget to unplug it). And then reconnect your phone again.
So, try these and please tell me the results. I was had some problems like yours.
And also, maybe you can check your device's registration status (developer registration) If yes, please try unregister and register it againg for development (http://prntscr.com/2fehv1)
Do a soft reset to your device and restart VS2012 again to solve this problem. (To do this: press and hold the power button and volume down button for about 10 seconds)
When I try to run the app via Visual Studio 2012 Express for Windows Phone I get the error message:
The application could not be launched for debugging. Ensure that the
target device screen is unlocked and that the application is installed
It worked 10 minutes ago, until I updated with OS version
8.0.10328.78
This was resolved by deploying the solution to the phone first by right-clicking the solution and selecting "Deploy Solution", and then running the app to debug.
I don't know why it's required to deploy the solution first. This wasn't required before the update when I ran the app.
Try either of the following:
1) Developer unlock the phone once more
2) Uninstall your application from the phone by hand, and build it again
I am developing Windows phone 8 app. When I try to run the emulator of WXGA or 720p I am constantly getting this error. Searching regarding this error leads to the conculsion that I should not run more and more app parallely. So I ran only VS2012 then also getting the error. I am having enough 4GB of RAM then also having problem. My friend's PC has 2 GB of RAM then also it works flawlessly in it. Anyone know what's the issue & best practice to run the emulator smoothly?
PS : I don't have REAL Windows Phone device :(
Just try rebooting your Windows 8 Phone. I just had the same issue, and rebooting worked for me while deploying on device.
Please ensure you have following to get rid of the error,
Minimum Hardware/software requirements (https://dev.windowsphone.com/en-us/oem?contentName=docs%2FGetting_Started%2FPreparing_for_Windows_Phone_development)
Valid developer license/account to develop windows phone applications
Enough free RAM (>2GB RAM should be free)
Not more than one instance of VS is trying to use same emulator.
If everything is holds good then try following,
Restart emulator & check if it fixed the issue, if not go to next step.
Go to Hyper-V manager and delete all the virtual switches related to WP. If it doesn't fix issue go to next step.
Go to Hyper-V manager and delete all the windows phone virtual machines. repair WP SDK from control panel.

In worst case, you will have to uninstall & install WP SDK.
Hope it helps.
The emulator may not work when its dedicated requirements are not perfectly matched. Emulator Requirements
You can always try deploying an app by selecting 'Device' in the emulator which will actually deploy the app on your phone and you can test it out.
note: Make sure you're using the right version of app which is to be deployed in its righteous OS version.
Also try to restart your emulator/device
Well. This might be happens because of some inner problems of Emulator. Because even me too faced this same problem some days ago. So, let me tel you what I have did and how I got rid of that problem. So, try as per my instruction and if this works. Just Mark it as an answer. else, comment what you have got after.
Check all Emulator VGA and VXGA and 720p
After you got that error, just tap Ok or Cancel in the dialog box and go to
Open Emulator -> Strat Screen will be shown -> goto All Apps -> Check your app name (It will exist and open your app and take screenshots)
I am sure this will be works for you.
Only restart the device or the emulator and the deployment will success
