hello
you can downgrade cas from cas firmware option. if dme ISN not working obd you can read it on bench. If you provide the VIN number we can guide you with connections. Also you can contact support via live chat for faster response

other tool with new Chinese key loaded-into cas is not working, oem key is still starting the car
Wbapg56060nm25401
Part no 9389115
Any ideas?
Does the downgrade need stable internet all the time?
I only have hotspot on my phone and it’s not the best.
Autohex shows key enabled in slot 10, but I used slot 9 in tango,
And shows no response when inserted in and out of slot, oem key no problems.

hello
for downgrade you only need basic internet to download files, problem will be from your new key. I do believe you are already in contact with our tech team.
