Help/Support UnJailbreak iOS 10.2 Yalu

[a4apple 5 iPhone 6s 12.4]

Hi, I'm new here especially with jailbreak. I have 6s and jailbroken my device. unfortunately i wanted to unjailbreak my device, I googled around and found numerous methods but there is an issue which i am fear with, which is that the cydia does not go away and causes problem on the device. I need advice on the way to unjailbreak my device completely and also stay at my current iOS 10.2 without losing any data. Please move this thread to the appropriate on if I posted at the wrong one. thank you!

But what about the data ? Can I backup my phone with iTunes (jailbroken) and then restore the data after the method you suggested? Will the cydia reappear on the iTunes backup ?

No, Cydia doesn't get backed up. But some Jailbreak files might.

How do I clear those files? Can I delete the tweaks first then backup? Will the files still exist in the iTunes backup? Sorry noob here. ?
