Hi,
using your tools I managed to decrypt mini 2 firmware, particularly the Ambarella one.
When I decrypted the Flight Controller (0306) it seems to have a second level of encryption, in the first bytes I found a clue because after the first four bytes there is the sequence 78 56 34 12 (xV4).
I tried the xv4 decoder available in your code, but it does not work, it seems like it is somewhat different.
Do you have any clues?
