[tphone]

Well, I tried to get this to work, but the bootloader just keeps saying (very quickly) No Image File on a gray screen. I formatted the card to Fat32, and renamed the extracted file to TITAIMG.nbh, but no joy. When the phone boots, I can see the file so the phone can see it.
I am reverting now using Olipro's unlocker, and the USB method. It's taking a while and generally a pain. The card method would be a lot nicer if I could get it to work.
