Have you provided external power when trying to do this?

Yes, i have attached an external power source while doing so, what's more, when reset, gnd and rx are connected,(All of them have to be connected,i've tried) the l surface mount led's that are power, pin 13, rx and tx start azy and going crazy and blinking, even when the other board is running only a blink sketch)

You need RX as well.
What are you connecting to reset? You can't just connect it to the reset of the other arduino.

When you said program it using another arduino I thought you meant through the programming pins not the serial lines. Without disconnecting the Tx, Rx and reset from the USB / serial chip on the broken arduino it is not going to work as the good arduino can not over ride the broken one.

I was connecting rx to rx, tx to tx, resetto reset, and also connecting the two grounds. Could you please tell me the correct way to wire it?

If you do that, you have to disconnect the wires from the broken FTDI. This will involve either removing the chip or cutting the tracks. It is not an advised thing to do.
