Hi, I have an Adata Apollo ZEUS8 DVR, and I have forgotton the admin password. When I setup the unit initialy, approx a year ago I (stupidly) deleted all other accounts that were preset, so the passwords ones suggested by my supplier do not work. (666666, 88888 etc etc). They suggest I send it back to them (which I do not want to do if I can help it), so I assume there is a way to reset it to factory defaults. I have tried removing the CMOS battery and leaving the unit unplugged for a week, also various other methods with no success. I am electronics engineer by trade, so have no problem with soldering any links on the PCB if required to do a hard reset. Can anyone help? Thanks.
