HTC HD7 won't start after failed update (Step 9 of 10) , hard reset has no effect!
Some days ago I started OS updating via Zune software on my HD7 and Updating process seems to be allright. But on the next reboot(step 9) the phone froze showing welcome screen with HTC logo.
I was patient and waited about an hour. After I disconnect my phone, take out and put batery back, and try to turn on the phone but nothing happens.
I tried to use Hardware Hard reset but it was not helpful(do not run). Now I have cool "dead" phone. How can I fix this problem?
