radio unit reset with bad serial

[WD0AJG]

I had my units working.  was connected and did a disconnect then I can't connect.  At that site I also have a teamviewer computer and checked the router and the radio unit was not connecting to the network.   I had it hooked up to the USB and it came up with a erronous huge serial number (117835012).  via setup but it does not show mac .  So we did a full reset push of the reset button for 20+ seconds and it did come up and had base IP address of 192.168.0.228 and via the microbit setup I was able to get it back to the 192.168.10.67 needed to access the router but it still has the false serial in the net info box I get all the rigt stuff for linking to the router but below I get:
Device connected!
FW/HW version suddessfully retrieved
SW version succesfully retrieved
117835012!=11783501

it also now has a new set of addresses for the ddns settings and I can not change them back to what I had before and with the huge serial it is not logging in
username shows rrc1258-117835012 
when I go search for it it does not show up via it's own host name that is now different from previous 
the old original serial should have been 13889.

How to I get it reset to access?

now I need to add, out of chance I tried to link back to the old name and it now links that I have it hooked to router with correct IP but going to the unit it still shows the wrong info:

This is what it shows on the radio unit via webaccess (knew the ip address and I had moved the webpage to a diff port) .

r46gud28.ddns.remoterig.com
rrc1258-117835012

the old name was :
vtd8kgu1.ddns.remoterig.com and I can link to that old name?

CRC mismatch, PID not changed!
