Unlocking an Apple device like an iPhone can be a bit daunting for those who are not tech-savvy. But don't worry, we've got you covered! In this article, we'll walk through the steps on how to unlock your carrier-locked iPhone 6s running iOS 9.1 using a tool called Auto Unlock.

Before diving into the tutorial proper, let's quickly understand what 'unlocking' an iPhone really means. There are several types of locks that can prevent you from fully utilizing your device:

1. Network Lock (also known as carrier lock): This type of lock is imposed by your service provider and prevents you from using your SIM card on a different network.

2. iCloud Lock: Also known as activation lock, this type of lock is associated with an Apple ID that was used to set up the iPhone before it was erased or wiped.

Now let's move onto how to unlock your carrier-locked iPhone 6s using Auto Unlock!

Step-by-Step Guide:

1. Download and install Auto Unlock from its official website.

2. Connect your locked iPhone 6s to a computer with an USB cable (make sure that both devices are turned off).

3. Open Auto Unlock on the computer and select 'Unlock' option.

4. Follow the prompts on the screen until you reach the 'Choose File' dialog box.

Here's where things can get slightly tricky:

- For Windows users: Click on 'Browse' to navigate through your computer files until you find the .ipsw file of iOS 9.1 that corresponds with your iPhone model (e.g., 'iPhone6,3_11D27B_Ded.ipsw' for an iPhone 6s).

- For Mac OS X users: Simply double-click on 'Open' next to where it says '.ipsw' under the 'Location' section.

Wait patiently until Auto Unlock finishes extracting all necessary files from your chosen .ipsw file. This may take anywhere between several minutes to half-an hour depending upon internet connectivity speeds and processor power of both devices involved in this process!

Once extraction is complete, follow these final steps:

1. Press & hold down Volume Down + Home button simultaneously while plugging back-in Lightning cable; keep holding them until Apple logo appears without releasing any keys whatsoever - it might take longer than usual due to firmware flashing occurring behind scenes.

2. Once you see the 'Hello' screen with your language options, select English (or whatever language you prefer), then tap on Continue.

Voilà! Your iPhone should now be unlocked and ready for use!

Remember that this method only works if:

- You have a carrier-locked device (i.e., it's locked to one specific network provider).

- The 'Find My' feature is turned off in iCloud settings before performing the unlock process.

- This guide applies specifically to iOS 9.1; unlocking newer or older versions of Apple's operating system may require slightly different steps.
