I recently had a customer ask me to reset a Samsung DVR. Of course, I first checked to see if there was a hardware switch to reset it. There wasn’t.
Googling the reset procedure, I discovered all of the resets for Samsung DVRs were pressing a combination of buttons on the front of the machine or remote. My machine had no buttons and none of the combination of buttons worked.
I did find a YouTube video that had a 7th combination of buttons that did work. This combination should work for SDR-3300N or the SDR-3040N and perhaps a few others.
On the remote, press:
in quick succession. I was able to get it on the first attempt. It will prompt you to reset to factory which you select OK.
Special thanks to 4k Vlogs for the info.
