Arris TG2492 (VM Super hub 3)

[eltremendo]

Hi guys, I'm working on very similar device CH7465 with NOSH firmware.
I was able to make a full dump and have convenient way to modify the internal eMMC.
My device doesn't display almost any messages on its console (just a few messages from bootloader) so no shell access is available.
I was also able to order another device from ebay and after clonning eMMC also the copy works Ok for accessing my internet connection.

I'd like to enable telnet/ssh access on this device. Did you make any progress with this?

Telnet and ssh can be activated, changing 0 by 1 in addresses  0x2A and 0x203 of /nvram/6/1 for TG862.
if nvram DB keeps same it can works. With breakout board taking, edit and get back file /6/1 in nvram partion and add or remplace rules with iptables.

Does anyone have the 9.1.116.608 firmware, or a mechanism to log in to this release? I can login to 9.1.116V using the mechanism from the NCC blog and I'm sure there must be other vulnerabilities to allow local login still. I looked at the two UARTs and only get output though someone mentioned the possibility of causing some sort of crash. Also from another site, it seems JTAG is disabled, so not going to try that route.

I got same problem, bucsay's mechanism is not longer work in new firms. Getting image of new firm from upgrade server and scraping file system. i hope find out to way to get acess.

you mount partition any edits is live unmount and you saved auto

how you mount ?
