无法将应用程序部署到设备

嘿，

我在Windows Phone设备(Lumia 800)上部署我的应用程序时遇到问题.我正在使用Windows Phone 7.1操作系统，这就是我的应用程序的目标操作系统版本.我的手机也被解锁了.我尝试通过几种方式来部署我的应用程序.首先，我连接手机并 与Zune同步.成功后，我用项目打开了Visual Studio，并在设备上简单运行了Application.我遇到了两种错误:

i have an issue with deploying my apps on Windows Phone device (Lumia 800). I am working on Windows Phone 7.1 OS and thats the target Os version of my apps. Also my phone is unlocked. I tried to deploy my apps on couple of ways. First I connect phone and synchronize it with Zune. After it was succesfull i opened Visual Studio with my project and simple run Application on device. I had experienced two kind of errors:

1.超时错误

2.无法连接到设备.确保设备已完全启动并已连接到PC.  

2. Failed to connect to the device. Ensure that the device is completely booted and is connected to the PC.  

之后，我尝试通过WPConnect连接到电话，然后运行VS并运行应用程序.通过WPConnect成功建立连接后，我遇到了相同的错误.

After that i tried to connect to phone by WPConnect and then run VS and run application. After successfully get connected by WPConnect i had the same errors.

然后，我尝试使用部署工具"简单地部署我的应用程序xap文件.再次出现相同的错误(我尝试使用WPConnect和Zune连接到设备).

Then i tried to simply deploy my application xap file with Deployment Tool. Again the same errors (I tried with connecting to device with WPConnect and with Zune).

我阅读了很多关于此的文章和论坛主题，但到目前为止没有找到解决方案.也许有人经历过相同的事情，或者对我的问题有解决方案. 

I read a lot of articles and forums topics about this and found no solution so far. Maybe someone have experienced the same or have some solution for my problem.
