Hi everyone,


I've recently downloaded the most recent update for the iPhone 3GS and tried to install it today. Every time I try to update the phone, the message "The iPhone "Sian's iPhone" could not be updated. This device isn't eligible for the requested build" appears. (See below)


Screen shot 2011-05-23 at 19.53.09.png


My iPhone isn't jailbroken, my iTunes software is up-to-date (10.2.2) and my laptop's software is up-to-date (Mac OS X 10.6.7).


I've never had this problem before... Sometimes when I plug my phone into the wall or in the laptop it says "Charging is not supported with this accessory" even though I'm using genuine Apple accessories, etc. I'm not sure if this helps you determine the issue.


Thanks in advance to anyone who can help me update my iPhone!

iPhone 3GS, iOS 4.3.2

    I was about to tell you that the download was probably corrupt, then I read about the charging not supported issue...


    Get an old toothbrush and clean out the dock connector. That should take care of the charging not supported issue. Probably some conductive grit in there.


    If the update still won't work, delete the file and re-download it.

    Hi there,


    Thanks for the reply. So I've cleaned the dock connector with a toothbrush and deleted the file... The same error message still pops up.


    Any other thoughts? Thank you

    Does anybody have any ideas? Update is still not working...

    3rd party security software or router security settings can also generate that error code. Any firewalls turned on? If so, turn them off. Navigate here and delete any and all .ipsw files you find. You will have to turn on show all hidden files & folders to see them. There should only be one, but delete all that are shown:


    ~/Library/iTunes/iPhone Software Updates


    Re-boot your computer when finished, try again.

    Hi wjosten,


    Thank you for the reply. Unfortunately this didn't help either... I've never had anything like this happen in 2 years - It really seems to have appeared out of no where.

    Try this next: Create a new user account with admin. privileges, try updating your phone using that account. Before connecting your phone, disable auto-sync under iTunes>Preferences>Devices. You can update software on any computer/account. Updating software does not touch any user data or settings. What you don't want to do is sync. If the update completes successfully, eject your phone when finished.

    Hi wjosten - sorry for the late reply - I just came back from holiday


    I just tried what you suggested, and unfortunately this didn't do the trick either. Same old message (before and after the iTunes update)...


    I'm so lost as to what to do about this. Thank you so much for trying to help me solve the issue - do you have any other thoughts?

    Does anyone have any thoughts? Still can't update my iPhone...

    Here's what is mentioned for your error in the updated version (June 22nd) of iTunes: Specific update-and-restore error messages and advanced troubleshooting


    Don't forget to update iTunes, the newest version is 10.3.1 Maybe a different USB cable is also worth a try.

    This device is not eligible for the requested build: Also sometimes displayed as an error 3194. If you receive this error, update to the latest version of iTunes. If you do have the latest version of iTunes, this can occur when you attempt to restore using an older .ipsw file. Try restoring in a new user to ensure that iTunes downloads a new IPSW. 3rd party security software or router security settings can also cause this issue, to resolve please follow Troubleshooting security software issues. Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see  iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod; follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store.

    Thank you Ingo2711 - this seems to be working


    I've never jailbroken my iPhone though - any ideas why this happened?


    Thank you so much for helping out!

    You're welcome, glad I could help

    I don't know why this happened, but I noticed, that this error is somehow coming up in combination with 3GS devices more often, than with the new iphone 4.
