Is There A Way To Flash The 480 Without Telnet ?

Hi all ,

I have a Vmdg480 which I had downgraded to R19 but somehow I messed something up and now I cannot telnet into it as I cannot get past the password/user combo.
The default MSO/changeme does not work and I have tried admin/changeme , admin/password but none of them work.I have tried and exhausted all the password possibilities that I can think of thru telnet, and none of them work ...

As I am having problems getting into my current superhub 480 thru telnet , I was wondering is there a way to flash the hub using a max232 cable ? [ like in the olden days of Ambit 250 ]
Any advice.

Managed to sort the problem out.
I changed the mac addy of my computer by using smac as my hubs mac had become the same as my computer's.
I was then able to telnet using normal o 192.168.100.1 command and use the MSO/changeme combo.
I was also able to get into the 192.168.100.1 as normal.
