ICSE / Wireshark final exercice : how to rebuilt the Pdf?

Hi everyone, in the last exercise, I managed to rebuilt the pdf file and it is perfectly readable, however the md5 hash generated from it keeps on been wrong. Is there anything special to consider when rebuilding the file? My method for rebuilting it was to remove top an bottom part that are obviously not part of the pdf, and also the newline character at the end of the last line, then concatenate everything together with a cat command. 

Thanks in advance for any hint.

      At last I though it is the newline character at the end of each chunk, but it also does not work.

        I also  made the concatenate with cat command but I don’t remember to have remove anything before concatenating.
