[Help] Reset admin Generic AHD DVR

Recommended Posts

I was install this DVR on my client, and they change the password.

Now they forget the admin password. Luckily i always make another user (with admin right) for this happening.

But i just know, with my "another" username i can not reset admin password.

Please help me, what kind of DVR is this ?

 

 

 

 

 

I trying telnet, i got prompt

GM Login:

 

Trying root:root root:123456 root:888888 root:8888 root:0000 root:000000

And other, all does not work

 

Please help me how to reset it ?

Hi

 

The GM in "GM login" stands for Grain Media (www.grain-media.com)

 

The most common default root password for these units is "GM8182" (without quotes)

 

Hope that helps

It's not working, thanks anyway.

I tried all the passwords below, none of them works. The DVR without the email/ftp alarms working it's useless...

any help from other users would be great.

i think the only solution is to dump the memory and search for the password hash in etc/passwd

does anyone has the firmware / dump? i have this DVR
