Whenever you're updating the vehicle's software, the system does a check to verify all the original, factory hardware is in place.

If you changed any factory modules, it has to be reinstalled prior to the update or it will be rejected.

That's why it's advisable that you always keep the original hardware.I learned this the hard way when I had swap my iDrive controller with the ceramic version from a 7 series.

Since you did indeed save the original cluster, just reinstall it and take it back to them to complete the update. After you reinstalled the original cluster, it's going to display some errors, including a red dot called a "tamper code" since the LCI cluster mapping was saved. You can ignore that, it doesn't need to be recoded for the update.

Afterwards, when the software is updated, you can then replace it back with the LCI cluster and then recode it.
