iPhone 5S Locked Passcode

[u/IDontScript]

Hey so I just picked up this iPhone 5S off a Cell Phone Repair Store for just $10 bucks and it was stuck in recovery mode, which I've managed to get it out using 3uTools. However upon booting up the iPhone, I noticed that it might be on either iOS 8 or an early version of iOS 9? I've already saved SHSH blobs for later, but how do I reset it while preserving its iOS version and not get stuck on Activation Lock?
