If you cooked the pads permanently, don't worry. There are identical pads on the other side of the motherboard, or so people say.

I did that, after cleaning as best i could i was still getting 1.765 or so on each pad, i tried soldering again and did a pretty good job but it still didn't work.
First of all each connection only gets 1.7 every now and then so it's annoying to measure unless i plug in the usb cable that make sure it's 1.7 for the next couple of mins for sure.
Logical since i assume it transmits every now and then or only during bootup.
Hooking it up to the adapter yielded the same results as before GND lights up RX seems to work but TX doesn't.
I checked the jumpers this time and got 3.1 and 2.1 on RX and TX.
For some reason i only get TX to light up if i short it with GND or with RX and the gibberish i got was from any place on the board if i touch it with RX including the shields so it's just electrical gibberish at this point.
No matter how i played with it including manually without soldering it didn't work...
The adapter shows up on linux but different from the guide and only 1 connection seems to be showing in tti0, on windows it's not better.
I'm beginning to think the voltage or adapter are the problem as i tried enough things to make sure it's not my fault
