Hi,

 

I basically started updating my Iphone 4s to OS 5.1, however i unfortunately was not running the latest version of itunes, so near the end of the installation and error message appeared, and now my phone will not turn on.

 

The phone just shows the Apple logo, which fades out and then reappears again,

 

I have tried rebooting (using the button and hold key) and the apple logo simply reappears

 

IS THIS FIXABLE?

 

Please HELP


iPhone 4S, iOS 4.3.3

    You can not update to iOS 5.1. You can only update to the current version, which is 6.0.1 for the iPhone 4S.

     

    Put it in DFU mode and install the current version.

     

    If that doesn't work, then you may have permanently bricked it by trying to install an unsigned version of iOS.

    Thanks,

     

    how do I put it in DFU mode if I cant even get any sort of screen up on my phone?

     

    It does not seem to even register it in Itunes which is a little strange

     

    when you say an unsigned version of OS what does that mean? I simply followed the instructions in the GENERAL folder on system upadate

     

    any further advice is greatly aprreciated

     

    Thanks
