互联网二三事

Windows Phone 7自2010年11月推出，一直受到广大骨灰级手机玩家的关注。近日部分三星用户纷纷反映在升级过程中遇到错误。尽管媒体对Windows Phone 7升级失败的事大肆宣扬，不过按照微软上周末的说法，当时全球只有100位左右的WP7用户遭遇了最新一次的Windows Phone升级问题。

原本以为微软会凭借Windows Phone 7在智能手机市场树立新的形象，没想到一开始就被一块大石头绊了脚。为了Windows Phone 7系统首次升级，微软在2月份发布了一个预备性升级，以便WP7系统升级会顺利，不料，这次预备性升级十分不顺利。

在2月22日WP7预备性升级发布后，部分用户反映在升级中遇到错误，不过微软称90%用户都升级成功。最不幸的要数三星WP7用户了，微软在24日暂停了对这些用户提供的升级服务，直到3月3日，微软菜宣布已经解决三星手机遭遇的问题并重新开启了升级服务。

然而，事实并非如此,部分三星用户再次遭遇升级问题，这次的代码为“800705B4”，同样用户在升级失败后只能恢复到出厂状态。微软发言人Michael Stroh周末表示：“在过去24小时内我们在紧张调查这个问题，并且已经找了800705B4的变通方案。感谢受影响消费者的耐心，我们会继续对升级推送进行微调，并尽快解决任何发生的问题。”

针对”800705B4″错误，笔者转载以下解决方法：
