Trying to install a stock rom on a samsung captivate
Assuming that your phone is Captivate (from the filename I897), here's a list of stock firmware files found on sammobile. They can be used with Kies too.

Alternatively, try Check Fus, which can get the right stock firmware for your phone.

I assume you know how to flash the files, if not, let me know and I'll dig up some good links for you. Hope this helped! Don't forget to accept the answer if it did.
