I have network unlocked AT&T HTC TITAN. For the last 3 days, I have been trying to unbrand it using goldcard method with no luck. I tried with two 2GB microsd cards, 3 USB sticks from sandisk and at least 5 single port card readers.
With one card reader, phone went up to “Loading” screen, then after around 5 minute, “No Image Found!” message came up.

I read thread

http://forum.xda-developers.com/showthread.php?t=1597837 completely. I followed all the instructions.
I tried to flash following three stock roms

My SD card is formatted as FAT32 with allocation unit 4096. I used the goldcard tool and image provided in those links. I renamed the rom file as “ETERIMG.nbh”.
I made a Y cable myself and its working properly. Phone and the card reader are getting power and phone is able to read the SD card.
Whatever I do, after 5-10 minutes of “Loading” screen, I’m getting “No Image Found!” error.

Now I’m out of any options. Please help…
Thanks in advance
