53 53 46 43 98 18 F2 0B 53 53 46 44 17 1A 75 02 SSFC..Ñ‚.SSFD..u.

And then there are strings for SSFA, SSFB and SSFC separatly:
SSFA:

I don't understand, I if add attire pic to SSFA, do I need to add 200 to the first SSFA (4A 13) or to the second one (AE 00)?Also I rechecked Andy's tutorial (checksum update is mensioned in his tutorial), but I did not get the point. Explain me please how to do this.
