My phone was working fine until a few hours ago when I looked and I had no service. A pop-up screen came up telling me to connect my phone to iTunes. Then it said I could only make emergency calls. I turned my phone off and turned it back on again. After I did that the screen would only show an iTunes icon and a USB cord. I connected my iphone to itunes. A pop-up screen then came up saying that iTunes detected my phone in recovery mode and that I must restore the phone before using it with iTunes. When I tried to restore my phone it said that the "iPhone could no be restored," and "an unknown error has occurred.(23)" I'm totally stuck. How do I get my phone to work again?

    The most common cause of this is hacked firmware - jailbreaking or unauthorized unlocking. In that case, these steps may not unbrick your phone.

    Error 23 means you're radio died. It's considered a hardware defect and Apple will replace it for you if still under warranty. I've seen a number of posts related to this issue. For those that have the 3 GS, think it's a good idea to get Applecare so the warranty gets extended a 2nd year. I just don't have any luck with GS products. When I had an Apple II GS way back when, the company decided to abandon it.

    Same thing happened to me. I had a passcode so itunes couldn't connect to my phone. I have valuable home videos in there.

    From what you describe, doesn't seem like you had a passcode. Are you able to access your data like text messages, photos, etc?

    I just don't have any luck with GS products.

    I drove a Lexus GS which ran well. OTOH, GS also refers to Goldman Sachs, and we all know what that means....

    FYI, iTunes error 23 is not related to the iPhone radio.

    Haha, I had a Toyota GS 300 that ran well too. Meant Apple GS products

    Here's the last 4 lines of my error log. The Genius Bar guy confirmed it was a radio error.

    2010-05-22 17:15:51.923 iTunes.exe[1880:10c]: radio-error = 512
    2010-05-22 17:15:51.924 iTunes.exe[1880:10c]: radio-error-string = 'Communication failure'

    2010-05-22 17:15:51.923 iTunes.exe[1880:10c]: *radio-error = 512*

    2010-05-22 17:15:58.432 iTunes.exe[1880:9dc]: iTunes: *Restore error 23*

    As shown in your log, the radio error is 512. 23 is a restore error. The support article below lists 23 as an "update and restore alert message" with recommended solutions. If 23 was a hardware radio failure, none of the suggested troubleshooting steps could work.

    "+When you are trying to update or restore your iPhone, iPad, or iPod touch with iTunes, the update or restore process may stop, and you may see an alert message in iTunes. You may also see the "Connect to iTunes" screen on your device:+

    +The alert message in iTunes may also include one of the following numbers (but is not limited to): 2, 4, 5, 6, 9, 13, 14, -18, 19, 20, 21, 23, 28, 29, -48, -50, 1002, 1011, 1013, 1015, 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612, 1639, 2009, 3004, 3013, 3014, 3015, 9807, -9808, 9844.+"

    That KB doesn't list an error 512. It does say error 23 may be a hardware issue. The Apple tech basically said the radio died and I was paraphrasing him. The point is, you can't restore the phone because some piece of hardware died out.
  • modular747 Level 6 Level 6 (18,245 points)
    No, error 23 is a restoring error which can be caused by a variety of problems including hardware failures. In your case it was caused by the radio failure.

    Others have reported getting error 23 during a failed restore and later successfully restored using the methods discussed in that KB. This could not have happened if there was a radio or other hardware issue.
