Received a TP-Link tp-wr703n router from china that had dd-wrt firmware on it version 24 sp2 (03/15/12) std. Need to flash openwrt on this router. Tried both factory and sysupgrade openwrt firmware files and receive "upgrade failed" message. Downloaded original firmware and this too failed. All this was run from dd-wrt web page for upgrading firmware.
Anybody know how to do this?
