Help needed for HTC Desire HD

[cabes]

I bought a couple of Desire HD phones in Singapore (I live in Australia) - One of the phones recieved an automatic upgrade which seemed to activate the mute button permantly during phone calls.I can hear the caller , but the caller cannot hear me.
I have checked the microphone still works - I am able to make a Skype call and send voice msgs.
Has anybody else experienced this problem - I would think that there would be a patch or download some where to correct the fault - otherwise I am to send the unit back to Singapore (at my cost both ways via DHL) because HTC company policy will not allow it to be fixed in Australia

If your not worried about the warranty you can reflash the phone yourself as this will void the warranty.

Edit: Sorry I think you would only void your warranty if you root the phone.

what does reflash the phone mean?

I'm not experienced at all in this area but I think you just reinstall the software on the phone.

From what i've been told on here, you just have to download the ruu (rom upgrade utility) onto your computer and plug your phone into your computer via usb and run the ruu.

This is where you can find stock ruu's. http://androidforums.com/htc-desire-hd/196270-htc-desire-hd-guide-updated-16-55-gmt-23-jan-11-a.html
