IOS5 Bricked my device

You bricked your Apple device?

Most developers use a different technique to update their IOS and this generally works even if the device is bricked.

The problem is that you may loose your data if you don't have a backup.

Disclaimer: No warranty that this will work. If you try this on a working device you can brick the device. Do that at your own risk!

1 - Try a Reset

  • Hold the Power button and the Home Button until you see an apple
  • Release and press power to see if the device reboots

2 - Download ipsw file from Apple and flash

Download the iPSW file corresponding to your device. IPSW are the firmware files they are coming from Apple and that's what iTunes does install without telling you.
  • Plug in your "bricked" device via USB to your iTunes Computer
  • In iTunes Option+click on the Check for Update button in iTunes.(To wipe your device and do a clean install, Option+click on Restore.)
  • iTunes will display a file dialog
  • Select the ipsw you downloaded
  • IOS will be installed. You can see a white progress bar, Be patient
  • When it is finished iTunes can prompt you for a device backup to restore
  • Follow the instructions and be patient. This can take an hour if you have a lot of stuff
Other methods

3 - Reset & Restore

  • Hold the Power button and the Home Button until you see an apple
  • Release and press power to see if the device reboots
  • If not plug your device via cable to iTunes
  • Select your device in iTunes left column
  • Click Restore. iTunes should go and fetch the latest IOS from Apple
    You should see a white horizontal progress bar download the setup/install
  • When the IOS update is finished iTunes will ask you for a previous backup to restore
  • You can say no at this time and verify that your device is OK or if you have a backup select and click. If you say no you can always restore later.
  • Sync your device. This will take a good hour if you have a lot of stuff
