you need to compare the official bin file and original dump in hex editor and cut out the un-nessary parts to get your bin file. In your case the hp site bin file has ec+main in single bin file and some unnessary bytes.
Just to confirm that dump from mcplslg123 is tested and working,
Worth noting in my case (where adapter sense and +19V were shorted in the adapter lead) that the Super I/O KBC KB3940 was suspected dead as well as F EON 25F16 (definitely dead, couldn't erase) No white LED at charge port laptop dead, 3V3 present at pin 8 of 25L16.
