Unlocking Dasan H660GM-A

1) login to 192.168.1.1 with admin : admin

2) go to maintenance> logs > system logs

3) search for "passwd" on that page

you will most probably get 3 results among them 1 is for default "admin" access, 1 is for a higher level access "superuser", and the other one is for telnet access
(both the username and password will be mentioned there)

4) login with the superuser account and go to maintenance > utilities > acl and enable telnet access for lan and save it

5) open telnet on 192.168.1.1 and then use the password as mentioned earlier in step 3 to login

6) type "bootcfg customer DASAN" and then do a factory reset to unlock the ont

(Note: after unlocking the WebUI credentials will change to admin : vertex25 and this will give you full access to all the settings and the telnet credentials will change to admin : 1234)

imo Dasan has much more advanced features compared to zte(which I used before this) such as separate DNS even for pppoe, beamforming and mu mimo support, inbuilt mesh and more

Hello,

I just got a 300 Mbps airtel fiber link installed 2 days ago.

In pursuit of configuring IPv6 on Dasan H660GM-A i have discovered that this ONT does not assign IPv6 address when PD in LAN is enabled and if i try to configure a static ip, i can only ping the ONT and not beyond, indicating there is no route for IPv6 WAN.

can you please share your superuser password as there is no logs with passwd prefix in my system logs.

Hello,


i did as you mentioned and was able to get the superuser password and subsecquently unlock the ont following the steps you have mentioned.

Kindly help to unlock Airtel dasan h660gm ont

 

[iYuvrajMehta]

does airtel get to know if the ont device was unlocked?

 

[nishantt6969]

no

 

[iYuvrajMehta]

no logs with "passwd" in my system log. tried resetting the ont without the fiber and still the same.
Can you share the superuser password if that works?

I did a factory reset without the fiber connected, but couldnt find the password in the logs.

my path to system logs is system tools -> system logs.
