Hi, I've got an s4 with the old "SIM card not detected" problem. I've tried almost everything to fix it but I'm still open to suggestions. My real reason for writing today is that I'm not sure if I should sell my s4 as is with original packaging, or if I should open it and sell it for parts. I know the screen is worth at least 100. Do you guys know what other parts I could sell? Or if I should just sell it all together?
