How to solve iOS error code S 1 1?

Error 1 1, you can try upgrading itunes to the latest version, and then try another usb port. Error 1 1 will take up disk C space when restoring the extracted software. If there is not enough space, skip the unknown error 1 1 and delete something to solve it!

Error 1 1: Don't open an umbrella or something. You should change your host file. Clear it, open C: \ Windows \ System32 \ Drivers \ etc \ Hosts, open the mode notebook, and then delete all the saved contents.

Then open itunes, click Update, and upgrade directly to the latest version, but it is too slow, and the network speed usually takes half an hour-an hour.

It is suggested to download the firmware of 5.0. 1 first, then hold down the shift key and click Restore to select the firmware you downloaded. Your itunes cannot be an old version, and it must be 10.5 or above.
