Clover CDR1660 firmware update

I have a Clover CDR1660 DVR for about 4 or 5 years now and so far so good. Working great.

My son found one almost new but it has the default firmware which is 1.6 version I think.

My DVR has firmware 1.2.4, but I cannot find the file that I used to update - drats!

Anybody happen to have this 1.2.4 firmware file?

Thanks,

Jim
