I do not recommend to change the firmware yourself without prior experience in this area. Chances to brick your device immediately are very high.
As of now it seems a good place to create your custom scripts within the /apps folder, which is writable and likely durable across reboots.
What's left is to figure out what mechanism your router-linux-distribution provides to call your scripts.
Since it's highly likely that some open source distribution is used, the first thing is to figure out which one it is(google, vendor homepage, product specifications, ...) and when the distribution name/type is found look/read for the possibillities for calling individual startup scripts.

for 6-10 I will answer tomorrow when I will redo the dump. I think I didn't perform it the right way and only got the squashfs out if.

6. I think I saw Uboot mention while analyzing the dump of an older firmware. The newer firmware only dumps the squashfs, no longer bootloader or kernel
7. no ideea how to do that, sorry

9. yes, usb is automounted as /dev/sda1

ok.. i think test / try and lets see way is difficult and time consuming and also risky..
therefore can you execute the below commands and attachment the output files to me ? ( thanks. )
I'm not sure I'm going to be able to accomplish anything here.
I have made the modifications, but unfortunately the router is branded by the internet provider and there is no official support or any way to download the firmware.
the provider pushes new firmware and can't think of any way I could intercept it
i guess what I was dumping the squashfs only using cat /dev/mtd5 > /var/tmp/usb/sda1/backup1.bin command.
it's a router. couldn't care less if they apreciate it or not, I might just even disable their remote connection to it if I get my way.
Hopefuly I will intercept de next firmware and get what I need.
it's not openwrt compatible yet and I wouldn't flash it to that anyway , because it's a gigabit router and being closed source openwrt would come without hardware NAT , wich means only 100MBps speed limit.
Hey all. Sometimes I'm tasked to change some router configs for the entire network (over 3,000 Cisco routers). Most of the time its a global config parameter so its done with a loop and an IP list as its the same configuration change for all routers. This is working OK.
However, sometimes an... (3 Replies)
