Q: I had my phone turned on and then suddenly the screen turned blue than started turning purple then turned off completely, I have tried restoring it but it says "unknown error occurred (4005) PLEASE HELP

Greetings BELMINMACKIC98,

If I understand you correctly, your iPhone went to a blue screen, then purple, then shut itself off. You have attempted to restore the iPhone and gotten an error 4005. Is that right?

Let's see if we can complete the restore process. I would suggest that you troubleshoot using the steps in this article - Resolve iOS update and restore errors in iTunes.

If this does not produce the desired result of a working iPhone, go on to this article - iOS: Restore errors 4005, 4013, and 4014.

Thanks for using Apple Support Communities.

Be well.
