Finding the right part

• On the iPhone, open Settings > General > About and tap the Part Number line. It switches to the model number, which starts with A.

• Models in the same range often look alike but use different parts. Open your exact model's page or check the compatibility list on each product.

• On many models the charging flex also carries microphones or antenna contacts, so compare it with the old part before you fit it.

• The earpiece speaker and the loudspeaker are different parts, so check the position named in the title.

• Glued back glass usually needs heat or a laser machine to remove. A housing swap replaces the whole frame instead.

• Board-level ICs need microsoldering gear: hot air or a preheater, flux and a stencil to reball the chip.
