Frequently Asked Questions

What is Apple iPhone error 3002?

Can I fix error 3002 without losing data?
Yes, most software fixes (updating iTunes, disabling firewall, changing network) do not affect your data. However, the last resort recovery mode will erase your iPhone, so back up first.
Does error 3002 mean my iPhone is damaged?
Not necessarily. It usually indicates a software or network issue. If recovery mode fails repeatedly, there might be a hardware problem, and you should contact Apple Support.
How do I put my iPhone in recovery mode?

Why does disabling antivirus help?
Antivirus or firewall software can interfere with TLS connections by scanning or blocking encrypted traffic. Temporarily disabling them allows the secure handshake with Apple's servers to complete.
