Did I break it? I think I did. (Gauges, EEPROM swap)

[Ipassgas]

I attempted to reset my mileage to zero. I bought a chip, and desoldered the old one. At least I tried to. 6 of the 8 pins worked, but 2 were resistant to melting. I cut the 2 pins off and tried some more. I still couldn't desolder them.
So I just soldered the new chip in, and soldered the affected area to the old solder.

Hooking it up, I was optimistic. Evidence shows, I shouldn't have been.

Would you try to redo it, or do you all believe I've ruined the chip and/or board?

I should probably try again, but you guys/gals are much smarter than me.

Thank you.
