Do you have a Kernel Panic?
Something went wrong with the firmware upgrade?
You bricked you'r router?

Here is a description of how you can repair your router by flashing the firmware with the serial port and Xmodem protocol.

Needed hardware: RS232 interface or our RS232 MOD.

If you don't have the RS232 MOD you will have to connect you'r RS232 interface to the right contacts on the router board.

Opening your Router will void your warranty!!
If you do this, it's on your own risk.

The folowing pictures will show you where the contacts are.

After connecting your interface with the router we can start flashing the firmware.

Start you'r HyperTerminal or any other Terminal software you like and connect with the right comm port.

The comm port configuration is:
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

After turning the route ON (pluging the power cable in the router) you have about 2sec to hit the SPACE key 3 times.
If you are not fast enough you will not stop the bootloader! If you did everything right you will get the following menu.

Linux Loader Menu
====================
(a) Download vmlinuz to flash ...
(b) Download vmlinuz to sdram (for debug) ...
(c) Exit

Please enter your key :

Now that we have this menu, we can burn our firmware with pressing the key "a"
After pressing the key "a" you will have about 5-10sec to send the firmware file to the router with the Xmodem protocol.
You don't have much time to search around for the firmware file, so i suggest you keep it at the default path of yout Terminal software
After sending the firmware file, the file upload will begin, which will take about 6min or more (can't remember the right time )
When the upload is finished the router will flash the firmware and then you will get the bootloader menu again
