Strange things are read, I refierio each iphone has its own personality, I tell you, A 4 which I got erased by mistake from iCloud, if you've done, you know black screen does not recognize the sim etc .... connect to itunes and has told me dectado iphone in recovery mode, restore and end of the process I asked the data, the methyl and perfect restoration, but mine data in clear echo 3 minutes when just delete from iCloud yours rather more precise time, give it to him.
I say when you put it in DFU is that you're going to ask for information when you finish the process, if you put it in DFU will not be able to restore that have active FIND MY IPHONE,
ICLOUD deleting it from now if you can restore without DFU.
give it time!
