Dahua DVR3204LF-AL - settings lost after each reboot

[ITGuyRo]

Hello everybody!
First poster here so please bear with me. The DVR was infected by malware. We issued the following commands:
After you login via telnet, issue these commands:
# rm -rf /mnt/mtd/Config/
# rm -rf /mnt/mtdbak/Config/
# reboot
Afterwards I upgraded with a firmware sent to me by a Dahua rep.:
498289_General_DVR3204HF-AL_Eng_P_V2.616.0000.8.R.20170315

The problem with the DVR is that whatever configuration I am trying to change, after a reboot, everything is back to default. This includes passwords, IP address, port and everything else. After a reboot I am always greeted by the initial Startup Wizard. Any advice would be kindly appreciated. Thank you!

Maybe put the Config files back to see if that fixes it.

Thank's for the reply. The same thing happened even before removing the config and performing the firmware update. I think it might be somehow related to the malware.
