Can you be a bit more clear? Are you arguing Linear B remains undeciphered?
“Of arms and a man of Troy i sing who first from shores”
Turns into absolutely unrelated gibberish when applying the deciphering phonetic maps, and comparing the meanings.
* nerd alert: I wrote the English with the word order in Latin, which has a endings-based freedom to word order allowing planned beats, in this case dactylic hexameter…Latin rap sort of when i think of it
This interacts with the highly inflectional nature of Greek; imagine a scheme for deciphering an unknown text into English which allowed the decipherer to insert, at any point, any word that might not be capitalized in standard English title case: to, for, the, of, and, but, with, ..., along with whatever plural or possessive markers they wished.

but then getting points deducted because I didn't use the right method for arriving at the solution
The typical solution would be to squint at it and write down the classical Greek form. That would be roughly equivalent to me talking English in Holland because I'm shy of Dutch, as a German native.
