How to translate a visual morse code?

Me and my buddy went through an easter egg in BF4. Our second-to-last step is to translate a morse code that's blinking on a lamp. I've recorded it, but have a hard time translating it. Any tips?
(I've downloaded the alphabet in morse code, downloaded many morse code sheets. I just need some advice)

IPhone iCloud account deactivate?

I purchased a iPhone from someone off eBay and right after they shipped it off they sent me a msg saying they forgot to take their iCloud acct off and to refuse the pckg and they will send it back to me overnight. Sounded kind of odd. Is there any other way I could remove the iCloud off the phone w/o having to go thru all this?

My Iphone 6 has issues picking up the Wi-Fi signal?

I recently bought an used Iphone 6 online however I was never infomed that the phone had issues picking the Wi-Fi signal. I literally have to be sitting next to the router in order to get Wi-Fi and already tried all the options I've read to fix it. I would like to know what could be wrong with the phone? If one of those repairs store could fix the problem? And around how much would the cost be? If anybody has had the same issue or have seem it before!
