I’m very frustrated with my right Joy-con

I have a very faulty R joy-con. It has many issues, I’ll list them here:

• cracked case (maybe that’s my fault)
• SYNC/SL/SR/LEDs not responding
• joystick drift

So I ordered a clear shell, a new SL/SR assembly, and GuliKit joysticks.

Aaannnd the second I try to open up the joy-con I strip a screw.

So I say “we’ll I’m changing the shell anyways I’ll just crack it open” and that actually works pretty well.

[edit: I forgot to add that when I opened it up I realized instantly that, oh no, the battery is leaking!!]

So I follow the guide and it says to gently pry up on the battery connector, so I gently do so, but the area to get to that connector is so so small, and I end up not unplugging the battery from the connector, but pulling the Whole Battery connector right off the motherboard!!

Now I either need a new motherboard or someone with soldering experience (I don’t have any and would just break it more). What should I do? Super frustrated right now
