I'm looking to try the IVS firmware on my 4300S. Can some one provide a link for the English firmware?

Hi Guys. I have a Qvis NVR which I believe is a re-branded Dahua NVR4416-16P with an old firmware 3.200.AD00.1 Build Date: 30-12-2013. I recently imported several units that are exactly the same however they have a new firmware. My supplier or Dahua refuse to supply any firmware. I have found a version on the internet which is DH_NVR4xxx_Eng_P_V3.200.0000.9.R.20150529. Will this work? Also I flashed another Dahua NVR with a wrong file by mistake. Can someone guide me how to flash the firmware in recovery mode? Thanks.
