Q: ANY ONE KNOW WHAT IS ERROR 3 IN ITUNES WHEN I TRY TO RESTORE IPHONE 5 TO IOS 7 IT STUCKS IN THE END AND AFTER 30 MIN THIS COME OUT "UNKNOWN ERROR 3" CAN SOME ONE HELP ME PLZ

Hi, may I ask where did you get this log from?

On a Mac, you go to finder, hold the Alt/Option key, and click Go on the top menu bar, then Library, then Logs, then iPhone Updater Logs. The last couple lines are what you need. This'll have the error code as well as the progress it made.

Hi everyone,
Right now I'm so dawm happy. I was trying to fix error 3 almost for 3 weeks and no success. Yesterday I loose all the love that I've had by my iphone 5 and tried the freezer metod not for 40 minutes, but for 12 hours. Today I woke up with no hope. Grabed the phone and put it restoring once again and PLIM "Hello" screen appeared. Sorry for my english ahaha, but just to say that right now you have a brick in your home, and you don't loose anything by leaving the phone 12 hours on the freezer. But be carefull, put the iphone in a box with rice envolving him.

Thanks!

Just want to say that I tried the freeze method for quite a few hours one night and only got changes to the error number. I then wrapped the phone in Saran wrap and left it in the freezer for a couple of days. I left the cord attached. I then put the phone in a freezer bag and put the whole mess in a bowl of ice and coarse salt.

Then I tried the recovery again. At first the phone didn't show up on the USB list, but eventually it did. At first it said the battery was low. After a few minutes it showed up in iTunes, and the recovery worked the first try.

Then it said it had to cool off before using! Odd. After it warmed up to room temperature I was able to boot it. But it needed to be activated. I was able to connect it to my WIFI, but the activation failed, saying the Apple server couldn't be located. The Apple website said the activation server was OK. I took a wasted trip to the Apple store, and was told the wait was three hours to see a tech.

I came home and plugged it back in to iTunes. For no particular reason, it asked for the appleid and password. This caused a lot of problems, because it was set up with a throwaway appleid. I eventually was able to reset the password via the website. After much tearing of hair, the phone activated. It  is now restoring from a six-week-old backup. I'm crossing my fingers.

IIf that worked I would like to see your logs above so I can see if we got stuck at the same spot.

My thought about the freezer trick rather than the NAND slow read/write as mentioned above is that it also rapidly depletes your battery since it's so cold in the freezer. I'm also wondering about the solder. Maybe I should put it on top of my oven (not inside the oven) the next time I make dinner so it gets warm, maybe to help with a little thermal expansion, and then toss it back into the freezer.

I just tried the 12 hour freezer trick, and that was not successful.

While I did in fact take a family member's upgrade and use it to early upgrade with Sprint to an iPhone 6, I'd like to get the 5S working at least to be an iTouch.

So, I have about a week before I mail it into a 3rd party supplier and get at least some cash from it to offset the iPhone 6 upgrade cost ($199).

My plan is to leave it in the freezer in the ziploc + paper towel + rice for at least 24 hours, maybe 48, to drain the battery as much as possible. After that I'll try one last time to do the restore on my computer.

Again, I might have a tried-and-true hardware failure as a result of some unknown impact/drop/etc damage. Or, I might not. No way to tell.

But I can't justify spending $40 on the tools and potential repair kits just to open it up and see the logic board broken.

My hunch is that there's a physical problem on the board in vicinity of the Cellular chip, hence the baseband errors I was seeing and the Searching... errors I saw prior to system updating.

As I said earlier I'll post back here either way and let you know what happens.

What about strong magnets like neodymium magnets? Any chance it will help?

Man your solution saved my iphone 4s ... thanks a million and greetings from Egypt

Here's hoping someone is still looking at this forum. I'm experiencing the same issue, have tried freezer trick which hasn't worked. I live in China, and my phone is from Australia so any apple store repairs are a 12 hour flight away. I'lll try anything!

Relevant log files are as follows:

Following up, leaving the 5S in the freezer for 2 days before trying a restore was unsuccessful.  Since I'm out of warranty and I've already replaced the phone with a 6, I'm now in the process of leaving it on top of my Toaster Oven (NOT inside it) set to 350 for 10 minutes to get the phone extremely hot. I'm then going to place it back inside the freezer to see what happens.

New iTunes out yesterday. No change.

Again, the phone is going to Gazelle anyway as a "does not work" trade-in for some cash, so I have nothing to lose except my curiosity.

Will post again if it somehow works. If it doesn't work, I probably won't post here again.

keneth , still with no solution the unknown error 3 ? i already make a lot of things ,most closer of solution for me was the infinite boot , after this , nothing

Resolve iOS update and restore errors

hi Kennethyoung,

do i really have to put it in freezer while recovering? because ive done it inside rice twice but didnt work out

i really appreciate ur help, i do

Everyone - your iDevice MUST BE POWERED OFF, NOT JUST A DARK SCREEN WHEN IN THE FREEZER! Otherwise the internals will not get cold as possible to maximize the physics effect of why the freezer method usually solves this issue.
