Hi guys. 
  
I was wondering if someone of you faced my issue too: 
  
I replaced the battery because i thought that this was about. However, when i log into my interface, date/time is being resetted! I've enabled NTP but again, problem exists... 
What do you believe that this could be the issue? 
  
Im unable to upgrade it via a firmware upgrade because i cannot find one. 
I found some of them and tried to flash it with them but i got a message 'upgrade failed'. 
  
My dvr is xmeye's cloud one. I tried flashing with S_V4.00.R10.20130513 file but again no luck at all. 
  
This is the screenshot of my dvr's info: http://prntscr.com/bhys5b 
  
any help would be appreciated.
