Thank you Mr Young!
I have never posted in these forums before, but was amazed the freezer Worked --Wow!
Quick Story--iphone 5 off warranty. Started to say 'searching' mult time a day.
I tried power off, shut down with both buttons, reset network connections. But nothing helped.
I tried to restore from iTunes, and got 'error 3'
My phone was then useless, spent 2 days retrying everything to get it out of recovery mode.
I read your freezer idea, but thought it was crazy. But, as a last resort I tried it.
Put phone in the freezer in a zip lock bag and a paper towel for ~40 minutes.
And it worked on the first try!!!
The phone was restored and updated from a cloud backup.
I was amazed! Thank you!
