I inherited a AHD6704t-LM from my brother. He had a break in at his house and they somehow reset everything on the recorder. The HD is formatted with Fat32 and has nothing on it, so obviously the password is not stored on the HD. Even the security questions he had are not the right answer any more. How would I go about resetting the admin password? I've tried all the obvious passwords, blank, admin, 12345 etc. I've tried looking everywhere for answers, including many suggestions including the superpassword, excel file, time pwd etc.
Motherboard has the number 0287195670 on it.
Please help!
