hi everyone. i have a htc hd2 phone. when turned on, it shows a grey screen and nothing shows. can it be fix or not. what should i do?
It depends, with the power off, hold Vol + (or maybe -) button, then press the power button and release both after a second or 2.
This should boot you into the recovery menu.
If it does, I can give you more possible things.
If it doesn't, and you see nothing but grey, well, I'd hate to say it, but it doesn't look good.
Your phone, was originally a Windows Mobile device, until some smart person found out a way to put Android on it. Because of this, the hd2 phones run a little strange sometimes.
Let me know if you get to the recovery menu.
