    Welcome to the forums! So Odin doesn't let you restore the device? That's odd, I never heard of that type of issue or error. Make sure you are in download mode and try a different USB port on the computer. Run Odin again and try restoring the file. You might also want to redownload the file or try another and see if that yields different results.
