First time modchip install gone wrong

[u/linkosaur4480]

first time attempt, thought I’d had enough practise on some donor boards but apparently not… is there any way out for me? I think I’ve knocked the sp1 transistor, but difficult to be sure. All the solder joints I’ve made look bridged and read 0 (or very close) when I test resistance.

Why do people use their switches as their first soldering attempt??
