Wifi and Bluetooth problem in HTC Desire HD.
I bought the HTC Desire HD Android 2.2.1 with built-in Software Number 1.72.405.3. But after two days, my Wi-Fi and Bluetooth connections have started to failed.
When I go to Settings to enable Wi-Fi, it says "Turning on…” for a few seconds, and then reports "Error".
And when I try to turn on Bluetooth it says "Turning on.." for a few seconds, and then nothing happens.
I have read that a software update caused similar issues in the past. But I have been on version 2.2.1 for some time, so why is it I'm having this problem only now?
The customer service in HTC's advice that I can try a factory reset – Settings -> SD & Phone Storage -> Factory data reset, but this didn't fix the problem.
Many thanks in advance for any help you can give me.
