I am trying to decrypt ac203_0405_***.pro.fw.sig firmware using dji_imah_fwsig.py.

dji_imah_fwsig.py -vv -k PRAK-2020-01 -k UFIE-9999-99 -f -u -i ac203_0405_***.pro.fw.sig

I am getting the following error:

Decrypted chunks checksum 0x6FE9C101, expected 0x6F070308 Warning: Decrypted chunks checksum verification failed. Continuing anyway

Am I using deprecated params for ac203_0405_***?
