I broke the ZIF connector lock mechanism of minus button when reassembling the Joy-Con. The Joy-Con works fine and the minus ribbon seems to be sturdy enough without the lock. Do you think it's safe to continue using this Joy-Con? I'm worried that it could lead to short circuit that cause damage to the Switch console itself. I don't know if it's possible.

If I have a JIS Driver set like this one :

[linked product missing or disabled: IF145-115]

(I bought it via the link in another Nintendo Switch repair guide on iFixit)

Which size of the screwdriver should I use when the guide specify a Phillips screwdriver?

Is Phillips #00 = JIS #00
