Find checksum and algorithm on a proprietary firmware file

I'm modifying a firmware file (.jic) JTAG Indirect Configuration File by hand, but changing data inside the file makes it unusable because there is a checksum somewhere in the file that has to be updated in order to make the file usable again.

I need someone to find where is a checksum inside .jic file and decipher which algorithm is used (crc32, etc).

The file is used by the Quartus II programmer for programming a firmware and it's giving a chechsum of 0D8FF292 when the .jic file is opened. I need to find where is this data inside of the file, so I can later change it.

additional info: the bits on each byte are reversed
