This worked great with 1.4.2. Thank you very much.
I was helping a friend with her NT and wasn't sure how easy it would be to do this with Ubuntu Linux. Piece of cake. For Linux users: (feel free to include in original post)
1- Download the SD_ROOT_NT16gbV4_6.zip from original post
2- extract the NT16gbV4_6 image file.img file only, you don't need all the other Windows garbage
3-rename the file to get rid of the spaces, I renamed it NT16gbV4_6.img
4-fire up the terminal and CD to the directory your file is in, mine was in the Downloads so (case sensitive of course)
5- find out what drive is your sd card, type in
note all the mounted drives, then plug the sd card in your computer (I use a usb stick card reader), and type
see which was added and ignore the number. Mine was sdb1 (sdb). Yours maybe sdc or whatever. Please use your head, you don't want to erase your computers hard drive by choosing the wrong drive.
6- while the sd card is plugged in, type in the terminal
dd if=NT16gbV4_6.img of=/dev/sdb
assuming that you are already in the directory your file is in, you have renamed the file as I did, and your sd card is sdb. Make any changes accordingly and press enter. It took about 2-3 minutes for the img file to be written.
7-then follow the instruction in the original post.
