Hello Keturah Hasija,
Thanks for reaching out to Microsoft Community. I understand how important for you to know what has been done to your device during and after the repair process.
However, I'm afraid we don't have that specific information stating what repairs were made. But as far as I know, for under warranty or out-of-warranty repairs, you are required to back up all the data on your device as it will be wiped out, then it will be replaced entirely.
I hope this helps.
