As I am an owner of an HTC Radar phone I was eagerly waiting for the Windows Phone 7.8 update to roll out. At the start of this weak I was one of the “lucky” ones who opened the Zune and there it was, an information that new update is available.So as eagerly as I was waiting for this update I pressed the Update button and patiently waited for it to end. But it didn’t take long and all my illusions were shattered. During the step 7. of the update process, when the Zune is creating a complete backup of the phone, the process failed and ended with an error number 800700B7. After several more unsuccessful tries I tried to find a bit more information about this error on the Internet. To my surprise the official KB article published by Microsoft mentions a lot of different error codes, but not this one. So after a few more tries with the help of my Google-fu I was able to find a few questions of some people who encountered this same issue. The resolution for them was to perform a hard reset of the phone before the update. Given that there is no way how to backup your Windows Phone it is really a great solution, you will only lose all your messages and application settings.

Quite pissed off I did the hard reset. And what followed next was rather unexpected. With completely wiped out phone, the Zune said that there is no update available, that I have a latest version. At this point I was red with rage. Fortunately the force update steps that can be found on the Internet helped (even thought I had to do them for each of the three available updates).

So my HTC Radar is finally running on Windows Phone 7.8, but to say the truth I am a bit dissapointed by the new tiles. I liked the old layout a bit better then this new one.

And the moral lesson of this story? Don’t expect too much, otherwise you’ll be disappointed or in a worse case pissed off.
