Yeah First dumps are ok but CDC3272G dump is needed to decrypt crc

Here Dash algo if someone need it

Set windows Calc to [Qword]
dec 290000km /32 > 9062 > Hex 2366 xor FFFF = DC99 > swap byte 99DC ;
Well 99DC is first 2 byte
Now select [Word] and push Rol 33B9 (2nd 2 bytes ) > Rol again 6772 (3rd 2 bytes), Rol again and again untill reach end km string ;

0x800: .FF FF FF FF FF FF 00 00 7C 7C 28 39 99 DC 33 B9
0x810: 67 72 CE E4 9D C9 3B 93 77 26 EE 4C DC 99 B9 33
0x820: 72 67 E4 CE C9 9D 93 3B 26 77 4C EE 00 FF FF 77

Now Correct crc in CDC3272G

Good luck yes
