Given the complexity, I’ll guess the puzzle’s completion is likely:
Wait — what if “Download-” is just a header and the rest is a cipher: Ciphertext: byhss ly tyz mhjbt msryt fy alatwbys Download- byhss ly tyz mhjbt msryt fy alatwbys...
But if it’s a Caesar shift of -1 for whole phrase: b→a, y→x, h→g, s→r, s→r → “axgrr” — not matching. Given the complexity, I’ll guess the puzzle’s completion
(download the bus in Egypt) — playing on “Download- byhss…” being a clue to decode as “Download- al autobees fi masr” but with letters shifted. Try reverse: If plaintext Arabic in Latin is
“ly” → shift back 1: kx → not clear. Try reverse: If plaintext Arabic in Latin is “msryt” → معرب? No. Let’s try: “mhjbt” might be “mikbāt” but not obvious.
It looks like you’ve provided the start of a phrase that seems to be encoded, possibly with a simple shift cipher (like Caesar cipher).
Let’s try on “ly” = “my” (l→m, y→z: “mz” no).
