RB1100AHx2 Dead After "Reset Configuration".

I brought a unit of RB1100AHx2 from my local reseller (Malaysia).
I reset the configuration before configuring it to support my local ISP.

However, right after I choose the “reset configuration” option via WinBox, the whole router become inaccessible regardless what I do.

I tried to hook up to the serial port and boot up the device, no boot loader screen on my hyper terminal.
Anybody here can help ?

I would try with netinstall. Hopefully the bootloader is still working and you have boot from ethernet selected. I sure you did, but just to make sure…did you use 115000 baud rate on serial conection on client?
