Firmware for generic DVR with internal MB GM8187T-16CH-V2.2

Hello,

I have a DVR with the motherboard GM8187T-16CH-V2.2 manufactured in China, after several tests believe there is resilience program in software this card because it does not work for the year 2016 because after reboot back to the factory date 2011-01-01, works only between 2012 and 2015, then I would try to upgrade the motherboard firmware but can not find anywhere this download if anyone have this file, I appreciate if available the download link for me.

Thank you
