Default Ecu mazda cx5 2015

I am the owner of a 2015 Mazda cx-5x
Mine broke ECU. I installed another same program and since then the car does not work. Can you tell me where I can find new software?
I was at the Mazda dealer and they said I needed to buy a new Ecu and software and it would cost very
much Do you know how to solve this problem?
Thank you

Welcome to the forum

Your description of the problem , it does not fail as you described.
Start over.
Why did you replace the ECU.
What were the test done to indicate a failed or failing ECU.
Was the replacement ECU from a ECU/PCM rebuilder?
Did you use your VIN and serial number of the ECU to purchase your replacement ECU?
During all this what were all the DTC when you scanned the ECU for both the original and replacement ECU?
