Replacing broken filters, capacitors, resistors ecc.
Hi, im a beginner and learning to repair with microsoldering iphones, i have an iphone 8 plus to repair, if i need to replace electronic components such as capacitors, filters ecc. do i need to take them from another 8+ motherboard or i can just buy a cheap iphone 6s icloud locked just to take the components i need? I dont know if the components are the same and works on all motherboards for each iphone model.
Thanks in advance.
