xming schreef:Recovery is possible!

Recently I've tried to flash the BGC fw and "bricked" the sagem, it seemed that my sagem doesn't like 60A042. After a bit fiddling I found out that one can recover from a bad flash w/o resorting to JTAG as long as you have a good recovery image.

Thing that you need:
- a dhcp server
- a tftp server
- s sniffer (tcpdump wireshark)
- some common sense

how this works? Booting in recovery mode and samgem will get an IP from dhcp server then do a netboot/etherboot and download the image from tftp server, then you can access the web/telnet interface again then reflash with a good image, that's it.

Step by step howto:

- start a sniffer
- boot the samgem in recovery mode by pressing the reset button and power on
- you will see that it asks an IP and should get it from the dhcp server
- you will see that it tries to download a file from an IP (write down this IP as tftp server) with a path (write it down) and filename (write it down)
- give your tftp server the IP address that you wrote
- rename the FAST3464_<whatever> to the filename you wrote and move it to the direcoty (relative to your tftp root) path that you wrote
- reboot the sagem in recovery
- surf to the IP of sagem (the one it got from the dhcp server)
- flash as usual
- done

As said earlier you need to find a good image, my sagem doesn't like 60A042 no matter what I do, but 60A040 works like a charm.
