Good Day,

I recently tried to update my HTC One X (at&t) phone using the manual installation process as I am unable to do it OTA. I downloaded the RUU from HTC support site and followed all the instructions but whenever the process reaches 29% in updating system it gives me the error code (155) unknown error. The progress bar on the phone fills up green and at the end of the bar there is a small triangle with an exclamation mark at the end. That is not all when I unplug the phone it shows the HTC logo with four exclamation marks, one in each corner. And the phone doesn't turn on at all, no matter how much I try rebooting it. I have tried the installation process a number of times with the same result. How can I resolve this problem and How can I get my phone to turn on as normal. Please help me . I really love this phone my wife bought it for me just two months ago.

Yours Kindly
Roger Fontenelle
