Dear, you tried many times and the same error happens? If so, it may be the hardware problem on your iPhone 4s. You need to check the hardware of your device.

Please restore on 3uTools again, and don't select the option "Retain User's Data While Flashing".
If you meet the error, please send me the screenshot of the error on 3uTools.
