I keep getting ILLEGAL_CLIENT_ID

[szupi-ipuzs]

I'm trying to crack LSC smart connect and I think I got all the secrets right:

{
  "key": "ufhnhpkh9np8t3rs9qda",
  "secret": "4c93vt3cm87a4wdgwas8hgvnhcdtt8xy",
  "secret2": "qmcy7pp5kafkdgq8cp3n45eqcrpwu5ng",
  "certSign": "28:23:66:B3:FD:B7:55:81:63:B8:FD:71:02:DA:3F:3E:F4:8D:E9:BC:66:06:93:FB:19:C7:8B:CF:5D:1A:3B:26"
}

These have been confirmed by memory dumps.

But I keep getting ILLEGAL_CLIENT_ID error from a call to loginEx. I think in this case I also need to set ttid and apiEtVersion to some non-default values, but not sure to what specifically... trying different combination, nothing works.
Tracing of the doCommandNative shows the app calls gives me this:
