DVR1604HF-A DVR firmware

[segrel]

Hi,

I'm looking for a firmware for my DVR1604HF-A DVR.

This is the most recent firmware I have found but it's no longer available online: DH_DVRxx04HF-X-E(V2.0)_Eng_N_V3.200.0003.4.R.20170816.bin

Does anyone have this file ?

Thank you.

I've found the firmware and its signature on this Dahua site:
