Bringing a Sagem F@ST 2504 back to life
Posted 21-01-08 at 06:56 PM by James67
As part of my efforts to crack the Sagem router, I managed to accidentally "brick" my Sagem router. Normally, if the router's flash memory has been corrupted, the router goes into a recovery mode which has a stripped-down web server through which you can load a new flash image. Unfortunately, I seemed to have got the router into a state where it was crashing at startup but wasn't going into its recovery mode.
Then I stumbled upon this link. OK, it's for the Linksys WRT54G router, but that's a Broadcom BCM6348 based router, just like the Sagem. You have to get the timing just right, but after a few attempts, the Sagem router started responding to pings. It didn't seem to be running a tftp server as described in the link, but it was running the recovery web server. Way hey! I gave it the 2404 flash image, and a couple of minutes later, I had a working router!
Unfortunately, I've already bid on a replacement Sagem router on eBay, so I'm going to end up with two Sagems. I suppose I can always flash them with the 2404 firmware and sell them on eBay as suitable for use with any ISP.

I've managed to get my first Sagem back to a state which looks like a Sky router again, but it seems to have retained some of the 2404 characteristics, such as a command-line interface via telnet (although sadly, this isn't actually a shell).
I've got my second Sagem, and actually, I think it's going to be quite useful for the final testing of any potential crack. I'll stick you working on my first Sagem for now though. |
