Hey all, have I damaged this xbox 360 controller circuit board beyond repair?

- The Blue circle is the parts I could not get to bind properly.
The issues and my process
So I had a pair of xbox 360 controller controllers with corroded battery terminal springs. I managed to successfully replace the first controller's springs, but the second I was having trouble with. The solder would not bind to the pad and it would form a lump that would break off under any pressure.
I consulted the internet and someone mentioned I just needed to crank up the heat. That didn't work and the binding seemed to get worse, further it looks like it is now burnt all the terminal pad.
The internet then told me to scrap away the surface as it might be residual flux and it should be fine underneath. It still fails to securely bind.
I suspect the corrosion ate so far into the device that the pad itself was too weak to bind. I also suspect I am an idiot.
Is there any saving this?
My Plan should I discover I borked it
360 controllers have additional terminals on the back which I might be able to connect to something instead of the battery pads.
As others have said, your pad is gone. If you're struggling to expose the trace needed to solder, it might be easier to find out which one of those test points corresponds to the battery terminal and solder a wire to that instead.
Here's a great resource I used to repair an Xbox one controller after destroying the pads in an attempt to replace an analogue stick.
