I have been reading this post for a long while and I did the download like I was suppose to do, and extracted the folders to my sd sandisk card, and when I take it to my f900bt and put it in and do all the steps, but when I select update sd/mmc(format) I get a message can't find winceimg.cks press any key message and then I can't go any further. If there is any help on what I am doing wrong will be greatly apreciated. ps I have used different sd cards, formatted sd card with fat32 and have to repeat the process 4 or 5 times.(PLEASE HELP)
