means, that You have written also PDA from Combination firmware, not only modem part. But You need to write only boot image from Combination firmware, not full Combination firmware.
Please do the following:
1. Write regular (common) Samsung firmware.
2. Write only modem (CP) part from the Combination firmware.
3. Perform "Reset FRP" via ADB operation again.
4. Write regular firmware again back into the device.
