the .pit file in the PIT box
BL_xxxx.tar.md5 in the BL box.
CODE_xxxx.tar.md5 in the AP box.

If you have a message FAIL! instead of PASS! remove the battery from the device and then turn it back on. Restart Odin ( test another firmware version) and start the process again being careful with files used and the boxes checked.
