Some time ago I purchased a generic dvr and Sony cameras from ebay to setup a home surveillance system.
I had it setup and running for a while and for reasons I forgot I took it down and for a couple of years it's been sitting in storage. I recently found it in a tub and thought I'd try to sell it or trade it. But it's been soo long I forgot the password to reset everything.
I was able to track down the manufacturer and sent an email to them asking how to reset the password. I received an email from Jerome in China telling me to follow the instructions he enclosed in a zip file. Enclosed in the zip file was an update and instructions which when applied would update the dvr and remove the passwords leaving behind a fresh install on the hdd. I hooked everything up according to the instructions and when I click on the update.bat file a small window opens up, some text rolls up the window and it closes in a blink of an eye. The window is supposed to stay open so I can type in some further commands; according to their directions. I contacted Jerome again informing him their update wasn't working, that was over a month ago and I haven't heard back.
I registered on this forum and did some searching for reset password and after reading thru a lot of topics I'm trying one thing I've read here. I opened up the case and removed the battery and in about 18 hours I'll find out if that trick worked (i read leaving the battery out for 24 hours might reset it). Also I read some topics about doing something with jumpers on the motherboard. But it wasn't clear as to what to do with them. There are jumpers on the motherboard. I've enclosed some photos if that will help. The second motherboard picture shows the jumpers in the middle.
The dvr is model number DVR-MP04V
Any help at all is most appreciated.
