Comcast Firmware upgrade on SB5100 Dave Mc 06-01-05

So after the big DNS outage I goofed around with my modem and managed

to reset my firmware somehow. I am at



Software Version: SB5100-2.3.1.6-SCM06-NOSH

Hardware Version: 3



which shows a copyright date of 2002. The old firmware, which allowed

control of the SB5100 was copyright 2004.



Comcast can't figure out how to send a firmware upgrade to me. the

live chat help person says they can't push a firmware upgrade to me.

=(



Any thoughts of how to get the firmware back?

Unplug the modem from the power. Wait at least 30 seconds. Plug it back in.
If the correct version of the firmware is not present, it will automatically
be pushed out at that time.

When you say "The old firmware, which allowed control of the SB5100", I'm
wondering what control you had. The only control that should be available to
you is to reset the modem. If you had more control than that, you probably
had the wrong firmware, and the correct version was pushed-out the first
time you power-cycled the modem.

It looks like you do have the latest firmware onboard.  My 5100 is only
about a month old and is running the
SB5100-2.3.1.3-SCM00-NOSH version which appears to be earlier than your
version.  I think the 2.3.1.6 is the latest from Morotola but some markets
have not pushed it yet.

SB5100-2.3.1.6-SCM06-NOSH is the farley latest production firmware for the
SB5100. The NOSH means "no shell". It also means no entry. There is no way
you had control over the SB5100 unless you had SB5100-2.3.1.3-SCM00-SH
"shell version" and had an orange SB5100 with a special connection on the
back of it that looked like a 1/8 stereo connection.You also needed a 9-pin
serial to 1/8 connector cable. There were some older revisions of code that
allowed some basic functions that the newer revision stripped away.

The only way to get the SB5100-2.3.1.3-SCM00-SH back it to have them do a
firmware push from SNMP back to your modem. Simply unplugging your modem and
plugging it back in will not restore your old firmware since a mass upgrade
was performed most likely. In reality you are not asking Comcast for a
firmware upgrade but a downgrade.
