Are you sure you used Kies?
If you used the Firmware Upgrade and Initialization in Kies3, and entered your model number and SN, it would have selected and flashed the correct firmware for you.
Take a look at this guide
http://www.samsung.com/ca/support/skp/faq/1072789
If flashing the firmware doesn't correct the problem, there are PC programs that will allow you to write the IMEI number back to the phone, as long as your EFS partition is not totally trashed and you can connect to the program

If you follow the guide, you enter your model number then your SN. If it says that your model number is supported, then you connect you phone with your phone in download mode and follow the rest of the prompts.
If your model number is not supported, then we need to figure out the correct firmware and flash it with Odin.
Going offline now. Will check first thing tomorrow, approximately 6hrs.
