i want to restore my i phone 5s , please help in here

Hi nandakishorekunuku,

I apologize, I'm a bit unclear on the exact nature of your question. If by restore, you mean restore it to factory settings (fully updated OS, erasing all current data), then you may find the information and steps outlined in the following article helpful:

you'll need iTunes 11.4 and it will not run on your old OS software.
