SMC D3GN Latest Version

Hey I'm just wondering if anyone here is using the SMC D3GN rogers modem and if they know what firmware/software version theirs is running. I'm running the same modem with teksavvy and their software version is different and I'm having some trouble. I am wondering if my modem was connected via the Rogers network if it would have been updated to a newer firmware which would be newer then what I have since that way it might work better with my teksavvy connection as well. I'm debating taking it to a friends house who has rogers and plugging it in there and seeing if it will receive an update from the Rogers network.

IMHO Teksavvy specific firmware (if it exists) would have a different filename/filesize/version number and would overwrite the Rogers firmware version should an update from Teksavvy be necessary.

Otherwise, just kick back and wait for Teksavvy to push an update for your SMC............

Well the update may not push through since its rogers branded modem, and it doesn't recognize the existing firmware.

Doesn't work like that. The firmware update is written for the SMC D3GN Gateway itself. It's exactly the same as a bios update (firmware for a particular model motherboard).

All SMC D3GN series bios are coded the same with some custom code added for the particular ISP (ISP code not present in original factory firmware).

A firmware/bios flash checks hardware (in this case SMC D3GN) then does a hash check on the installed firmware to determine installed version then proceeds with the flash (if necessary).

They're all .BIN files and they're all written to support the SMC D3GN series hardware within.......

elitefx you have become quite the expert on here! kudos to you!

one fun fact is that the modem does not do a hash check to determine the software version, it does however do a check to make sure the bundled certificate in the .sbn file is signed by an authority in order to proceed the update (which can be a downgrade too as i've done in the past)

I believe the current Rogers version is 3.1.4.45.2. The version required for Teksavvy (and other TPIA) is 1.4.0.40. The version numbering scheme changed, and I'm guessing that this new 3.1.x.x.x version would be equivalent to 1.4.0.45 in the old numbering scheme (so, the new one is just a few sub revisions newer, not a major step--edit: that didn't stop me from calling it 'way' older a few days ago...).

Only Rogers can push firmwares. Rogers almost never does that for Teksavvy customers. The only two times they did was on SB6120, and those occasions were both for all units in the field en masse. Some people talk about getting Teksavvy to request an upgrade for a single customer's modem, that NEVER happens.

Finally, I have a report from a customer that downgrading from 3.1.4.45.2 to 1.4.0.40 actually fixed a line stability issue. Seems very strange to me, but that's the information I've got

.

ArhurWinslo, do you know where is the Rogers admin password (or admin password in general) is stored? Is it part of the firmware, or is it in the certs or config file or something?
