Checking each IOS file, you can see that the file name is as follows.
- C891F >>>> “c800-universalk9…“
- C891FJ >>>> “c800j-universalk9…“
Answer: Either can be used
“c800-universalk9…” and “c800j-universalk9…” have different file names, but the contents of the files are exactly the same. So it doesn’t matter which file you use.
