iTunes restore error -1 usually means the baseband chip needs to be removed, reballed, have jumper wires attached for points where the solder connection would be weak.

Here is the solution as shown in this link:

It's fix that usually only people that do micro-soldering can do.

Error-1 is usually

Baseband CPU/chip/baseband output of power supply is abnormal.

Please do a restore using 3UTools and post a screenshot of where it fails like this

or better yet use the pro mode it gives more details
