That's a good sign.
Good.
I hope that includes the 1.8v adapter as well. It's better to use an adapter that runs at 1.8 volts than to "fix" a 3.3 volt adapter to run at 1.8 volts.
Not really.
That's the part I don't understand. What "others"? Do you mean the lights for the Rx and Tx terminals? It's because you apparently wired them incorrectly.
Anyhow, just a small quote to help you remember the terminals (I don't remember the exact wording, but the general idea is there):
Good!
Try using your current adapter and let us know. I have a feeling that it is going to work. You now have the correct voltage and the correct wiring, and barring an issue with the adapter, it's supposed to work.

I got the parts but i couldn't get it to work :\
Not with the USB-TTL and not with the FT232RL Adapter and not with the one i had to begin with.
its all the same i get the tty0 connection just from ground but RX or TX add nothing but they had voltage, i tried swapping them i tried the FT232RL adapter with the 3.3v jumper no luck at all.
i'm going crazy questioning either my soldering skills but i'm so sure its correct or the device itself
Any ideas?
