Surprisingly, after May 14, 2015 Microsoft has said that Windows Phone 8 devices will no longer be developer unlocked due to MS security certificates expiring. This date has obviously come and gone, nonetheless here I am with an HTC Windows Phone 8S, a phone that won't receive 8.1 update but in need of some developer testing. Does anyone know of a way around this to developer unlock a phone? I've tried changing the date back to pre-May 14, however, this does not work.
You can't unlock it as a Windows Phone 8.0 device, but you can upgrade it to Windows Phone 8.1 through the Windows Phone Developer Preview and then developer unlock it.
While early versions of the Windows Phone 8.1 preview did not support the 8s, the update has been available for that device since September (see http://blogs.windows.com/bloggingwindows/2014/09/24/new-update-for-windows-phone-preview-for-developers/ )
We need to unlock a Windows Phone 8 device in order to deploy our app that still supports this specific platform.
The process was working some months ago without any problem but now, Windows Phone Developer Registration Tool, available with SDK 8.0, returns the following error:
We have already tried with different devices (with the date set correctly: UTC +1 Rome)
HTC 8S
Lumia 720
Nokia 625
all with the same result.
We have tried to unlock our devices for an entire week, so it does not seem a temporary problem.
The devices and the pc have both a working Internet Connection and aren't running behind any firewall/proxy at all.
We have no problem at all, unlocking WP 8.1 devices with the proper Windows Phone Developer Registration Tool for WP 8.1
Do you know if there's any technical problem on the Microsoft side?
Is the Windows Phone WP 8.0 unlocking process still supported by Microsoft?
As of May 13, 2015, you can no longer developer unlock Windows Phone 8.0 devices. You have to upgrade them to Windows Phone 8.1. I don't have an article to point to, just an email I received from MS to the email address associated with my developer account:
If you have a Windows Phone 8.0 device that you use to test your apps,
please read this mail.
The Windows Phone 8.0 certificate that validates developer unlocks
will expire today May 13, 7pm, Pacific Daylight time.
We recommend that you re-unlock your Windows Phone 8.0 test devices
prior to today 7pm, to continue testing for another 24 months.
After today, no Windows Phone 8.0 device will be able to be developer
unlocked, and you will have three options to continue testing Windows
Phone 8.0 packages: – Update the phone to Windows Phone 8.1 and
unlock it for developer testing – Submit apps as beta through the
Windows Dev Center and test with Windows Phone 8.0 devices – Test
Windows Phone 8.0 apps via the Windows Phone emulator
Any Windows Phone 8.0 device currently unlocked will continue to be
unlocked and work as a test device until its certificate expires. To
maximize the time available to test with this device, please lock then
unlock the device before May 13, 2015 7pm PDT.
Note that this change has no impact on apps available in the Windows
Phone Store, has no impact on Windows Phone 8.1 devices, nor will it
impact customers with Windows Phone 8.x devices.

I tried registering my Lumia 820 using WP8 SDK Registration tool and it succeeded. So I believe there is no technical problem on Microsoft's server.
It is still possible to unlock Windows phone 8.0 devices. Only 7.x devices can't be unlocked now as mentioned in this article
As you are getting time error, Try disabling "Set Time automatically" from Settings menu as per the official documentation
Are the date and time set correctly on the phone? In SETTINGS | date + time, turn off the Set automatically setting and then retry registration. After registration succeeds, turn this setting on again.
Make sure your phone also has some internet connection, such as wifi.
I've had some problems sometimes registering some WP devices as developer devices. I've never had this particular error, but maybe this will work.
When the device is connected to the computer, in the taskbar click in the icon which shows that a device is connected (the one where you can "Safely remove" the device) and right click on it and select the show devices and printers option. When it opens, you will see all the windows phone devices you have connected to the computer. Disconnect your device and uninstall it and its drivers by selecting the appropriate option after right clicking on it.
Connect it again, it should now install its drivers again.
And just in case, if you have the correct date/time on the device, just confirm they also match the region/location set in the device. for eg- suppose you have set the time to indian standard time (IST) but the region of the device is set to that of USA or some other location.
If the WP8.0 answer or other date/time finagling does not help, another recommendation to try is to just reboot the darn thing after changing the time settings to manual.
I ran into this error with a Windows 10 Phone today. I tried adjusting the time settings from automatically set to manual, and ensured all was in sync between the Phone and PC, but I still received the 0x64 error code. I tried another PC, to no avail. By chance, I decided to reboot the phone. After rebooting and launching the PhoneReg tool, all was happy and I was able to unlock the phone and deploy my app.
Check windows phone date+time = pc date+time
date+time Set automatically turned off
unplug de phone and reconnect
Since installing VS2013 Update 4 I can't load any of my Windows Phone 8.0 projects. I get told that I have to upgrade to my PC to Windows 8.1. Anyone know how to fix this?
Apparently this isn't a supported configuration on Windows 7. Not sure how I even got into this state.
everytime I try to start my app on my Lumia 1020 I get this error:
Error: DEP6250 : The Device runs on a not supported version of the OS
(I translated it from german...)
I "unlocked" my phone a few minutes ago so I think that this won't be the problem.
I also searched for an update but everything is fine...
I used the free Visual Studio express 2013 for store developers
Does anyone have ideas?
Your problem is that you are probably trying to deploy a Windows Phone 8.1 app to a device running Windows Phone 8.0. That is not possible. You need to Either create a Windows Phone 8.0 app and run it on the device or update your device to Windows Phone 8.1 in order to run WP8.1 apps. Windows Phone 8.0 apps will work on WP8.1 but the other way around will not happen.
I have installed Windows Phone 8 SDK, openened the VS express for Windows Phone,
created New Project with simple app, pressed F5, but the emulator wont start.
Is comes up with error:
Exception from HRESULT: 0x89721800
I don't have any network drivers installed which should be called Windows Phone Emulator.
I have Windows 8, with built-in Administrator account and full privs.
P.s. Main reason for this I want to deploy some apps on my Nokia Lumia 800.
I have unlocked it, but when i was deploying app with deployment tool, it came up with the same error message.
P.p.s I've installed Windows Phone SDK 7 and there the emulator worked, but i can't find any way to deploy app to phone
I blogged about this a couple of weeks ago. You can see the full details here: Resolving windows Phone Emulator Problems
XDE cleanup, and Hyper-V is a very common reson for problems with the emulator!
Regarding deployment to phone from windows phone sdk 7, remember to change debug device from "Emulator WVGA 512 MB" (or what ever you use) to "Device", and always start Zune before your start debugging and deployment.
If you had installed Windows 8 (Single Language or Home Edition) with Windows Phone 8 SDK you can't develop mobile applications because it doesn't support Hyper-V.
The only way to work with Windows Phone 8 is to change your OS to Windows Pro or higher.
