Well, unless you have erased the booloader, I think you should still be able to reflash the device using bootloader commands, even via xmodem if the loader allows it. > > 3).

I think you should have a look at this page [1], where there are ressources to create custom rtl8181 firmwares. > > W.P. [1] http://rtl8181.sourceforge.net/ -- Regards, Florian
