I have a Sitecom WLR-4100 here and I want to try DD-WRT on it, I haven't found any information about this device but I know it's quite common (in the Netherlands?)
I opened it up and took pictures, I am willing to test a firmware on it... I am not sure if it has serial (maybe those 4 holes in top right?)... I don't know anything about serial at all but willing to learn

The picture of my WLR-4100v1002 is pretty different than the ManIkWeet one. I am aware of another version WLR-4100 v1001.
Supposing ManIkWeet has V1001, they replaced Ethernet Switch RTL8367RB with QCA8337-AL3C in V1002. Even the SoC looks different.

So this thread should be moved to the Ralink sub-forum as it is not a Broadcom device.
Do I have to open a brand new post in Ralink Forum?
Or does the adminstrator move this thread?

Looks like they've locked things out. Normally, you'd be able to type in 'help' to get a list of commands and go from there. Not sure if you'd get any information by selecting to TFTP firmware and flashing stock firmware to it. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

I got this:
2: System Load Linux Kernel then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)

I tried some operation which were not proposed in the menu:
_____________________________________________
