Dear Community friends,
This post features the advanced method of resetting an ONT to its default configuration. Please see below for more details.

ISSUE DESCRIPTION
I am unable to reset the ONT to its default login credentials. I have not connected this OLT/ONT to U2000, so there is no auto config upload t ONT.
Because I don't have the right credentials, I can't reset it from the webpage. How can I reset the ONT to its default login credentials? <?xml:namespace prefix = "o" />
All the ways I tried have failed:
1. the ONT HW reset button pressed more than 10s;
2. the ONT factory reset command from the OLT console.
3. upgrading to a newer FW from V13 to V15 to V17 does not help - old credentials still remain.
You can telnet the ONT via OLT and execute the restore manufactory in the WAP mode.
Input MA5600(diagnose)%% telnet frameid/slotid/portid ontid

input root/admin or root/adminHW
SU_WAP>restore manufactory
success!
SU_WAP
Please note that reverting to the factory settings will lose the user's current configuration.
