hi all, this is my first message and I hope you'll can help me with this problem.
I have a dvr samsung shr-2040, and I only watch the post "clock battery fail" on the startup screen. I've read is a cpu protection, but I'm trying to upgrade the flash by com serial and I can't connect with the dvr.
Does anyone knows how to fix this trouble?
Many thanks in advance.

please message me privately and I can help solve your issue. or you can call our samsung gvi tech line at 888-595-2288. thanks
