5 Most Effective Methods to Unlock Apple iPhone XS in Lost Mode

Numerous security features make all Mac devices like iPhones, iPads, and Macs stand apart from the opposition in terms of user data safety. Lost Mode is one feature that locks your lost iPhone or other Apple devices so nobody can get to them.

If your device is gone, you can use the Find My application on your other Apple device connected to a similar account to unlock the lost iPhone.

If your Apple iPhone XS is in Lost Mode and you don’t have the foggiest idea of how to restore it, relax. This guide will cover every one of the techniques that you can use for iPhone Lost Mode unlock.

Part 1: What Will Happen When iPhone Is in Lost Mode?

The Apple iPhone XS Lock feature permits remotely locking a lost Apple iPhone XS to prevent people from using its data. If you set a password for a device before enabling the Lost Mode, you will need this password to unlock the Apple iPhone XS once it has returned to its proprietor.

The Lost Mode menu will ask you to set one if it has no password. Password is obligatory to stop Lost Mode once a device is returned to the owner, as Contact ID or Face ID won’t work for this reason.

Send a Custom Text Message: When you sort out your lost iPhone and put it in Lost Mode, another supportive feature accessible to you is a custom message shown on the Lock Screen. You can enter any message to let an individual who found it realize this iPhone is lost. This way, you can demonstrate a phone number for the other person. That will expand opportunities to get your device back.

Erase Data Remotely: Lost Mode allows you to delete the Apple iPhone XS if you believe it’s been some time since it’s gone and you don’t think you can get it back. Doing so will ensure nobody will use your user data.

Track Your Device on Map: An owner can follow their lost iPhone on the map through the Lost Mode menu. The menu additionally gives email warnings to show the last location of your Apple iPhone XS.

Play Songs: Playing a sound might assist you with finding your lost iPhone if it’s still close by. The Apple iPhone XS will play a sound at top volume, no matter what volume level was set on the Apple iPhone XS device when you lost it.

1. Remove lost mode by entering the correct passcode

The most straightforward method for unlocking the Apple iPhone XS in Lost Mode is entering the password on the actual device. If your device was protected with a password before placing it in Lost Mode, enter it again.

If your device had no password while placing it in Lost Mode and you’ve entered it into iCloud while placing your Apple iPhone XS into Lost Mode, utilize this password. That will help you unlock lost iPhone, and you can start operating your Apple iPhone XS again.

2. Remove it from Find My in iCloud

One more method for unlocking the Lost Mode on your Apple iPhone XS is to utilize the Find My iPhone application on the official iCloud site. Follow the steps underneath to do so:

1. Go to <www.icloud.com> and utilize your account details to sign in.
2. Click the “Find My iPhone” button and select all iDevices.
3. Pick the Apple iPhone XS device you need to unlock in Lost Mode and tap the “Lost Mode” button.
4. Click the “Stop Lost Mode” button to remove the lock from the phone.
5. Confirm this activity by clicking the “Stop Lost Mode” button again.

3. Use iCloud DNS Bypass

Domain Name Service is an unsafe technique that utilizes a domain name to an IP address. iCloud stores every iPhone’s information, and when an iPhone is set up, it sends a request through DNS to ensure whether the Apple iPhone XS device has an activation lock enabled.

The DNS bypass will send a fake “device isn’t locked” message to iCloud through a server. It allows you to go through the setting of your Apple iPhone XS and access some applications. However, you must remember that this technique works on iOS 11 or older versions. Follow these steps to utilize the iCloud DNS bypassing strategy to unlock lost iPhone:

• Insert SIM in your Apple iPhone XS, turn it on, and select a preferred language and your location.
• A WiFi screen will spring up. Tap on the “I” icon. If you are now connected with your WiFi, tap “Forget this Network.”

• Tap on “Configure DNS,” and enter a DNS server as per your region from the list underneath:

USA: 104.154.51.7

Asia: 104.155.28.90

Europe: 104.155.28.90

South America: 35.199.88.219

Australia and Oceania: 35.189.47.23

• Clean old DNS server off of ISP modem, select and connect to a WiFi network. Click the Back button when a popup says that the Apple iPhone XS device is attempting to connect to the Apple servers.
• You will now be on the DNS bypass screen. Pick the applications from the list to keep using your device. However, only a handful of applications are available through this.

4. Use Emergency Call

This technique is the most widely recognized one. You can bypass your iCloud activation by settling on a fake Emergency call. Nonetheless, it is accounted for that this strategy probably won’t work for everyone.

If your Apple iPhone XS is on lost mode and attempting to unlock it, you can try using this method. Follow these steps for making an Emergency call on your iPhone in Lost Mode unlock:

• Click the “Emergency Call” option on your locked device.

Click here


• Dial “*#96274825*0000*1#,” then, at that point, press and hold the dial button for 10 to 15 minutes.
• If it’s not working, try changing the last digit from 1-9. If this doesn’t work, have a go at setting 0 after 9. Remember to hold the dial button.
• Press Home, and it will return you to the beginning screen. Select the language and country, and the activation screen will never appear again. Now create a new password after iPhone Lost Mode unlock.

5. Apple iPhone Unlock

Apple iPhone Unlock is a site that can assist you with iPhone in Lost Mode unlock. You must give them your Apple iPhone XS’s IMEI and model number to get their services.

The benefit of Apple iPhone Unlock is that they keep themselves updated with the latest technology. They are educated regarding their tool’s advancement by giving updates every time.

Critical Features of Apple iPhone Unlock:

• As per their site, Apple iPhone Unlock can work with every one of the Apple iPhone XS devices going from iPhone 4 to iPhone 14 Pro Max.
• Don’t bother downloading anything to your PC or phone like others. Another iPhone lock screen expects you to download their tool or software to work.

Before bypassing the Apple iPhone XS lock screen, we want to boot it in Recovery or DFU mode by adhering to the on-screen guidelines. The Recovery mode is suggested for the iOS lock screen. However, if you can’t activate the Recovery mode, you can figure out how to activate the DFU mode from their official site.

You can choose the right information from the dropdown menu if the information isn’t right. Then, at that point, download the firmware for your Apple iPhone XS.

Luckily, we’re here to provide a series of dependable and secure solutions that will help your iPhone in Lost Mode unlock.

Apple iPhone XS Asking for Passcode after iOS 17/14 Update, What to Do?

If you’ve recently updated your iOS iPhone and iPad to the iOS 17/14 operating system, you may notice a bit of a bug where the Apple iPhone XS displays the passcode lock, even if you haven’t got a security code in place.

This obviously means you won’t be able to access your phone, and in many cases, you’re going to want to get back into your phone as quickly as possible. However, this may be easier said than done. Fortunately, today we’re going to go through multiple solutions to help you get your device working as it should!

Part 1. Don’t try passcodes blindly

One of the worst things you can do when faced with this situation is to enter passcodes blindly. Perhaps you’re trying random numbers and letters, or you’re trying passwords you’ve used in the past. If you get it wrong, you’re going to be locked out of your device for a long time.

The more times you get your code wrong, the longer you’ll be locked out, so avoid doing this at all costs, so make sure you move straight onto these approaches to get your phone working as quickly as possible.

Part 2. 5 ways to unlock iPhone after iOS 17/14 Update

2.1 Try a default passcode in your family

While we said, you shouldn’t type in random numbers to try and guess the password, of course, if you have a standard family passcode that you use across all iOS devices, perhaps an admin password or just something you use for everything, it can be well worth a try.

In reality, you get three attempts to put a passcode in before it locks you out, so try two passcodes that your family uses to see whether this will easily unlock your device. If you brought your device preowned and still have contact with the owner, they may have a passcode you can try.

2.2 Unlock iPhone with an unlock tool

The second approach you can take if you don’t know the passcode and can’t get it unlocked is to use a powerful software solution known as Dr.Fone - Screen Unlock (iOS) . This Wondershare software application completely unlocks your phone, even if you don’t know the passcode.

This software is easy to use and incredibly simple, yet it gets the job done. If you’re looking for a quick way to get your iOS device back up and running with full access after an iOS 17/14 update, it doesn’t get much better than this. Here’s how it works;

Step 1. Download and install the Dr.Fone - Screen Unlock (iOS) software to either your Mac or Windows PC and open it, so you’re on the homepage. Connect your iOS device to your computer using the USB cable and wait for the software to recognize your device.

When it does, close iTunes if it automatically opens and clicks the Screen Unlock option from the main menu.

Step 2. Click the Unlock iOS Screen option.

Step 3. You will now need to put your device in DFU mode, also known as Recovery Mode. Fortunately, this is easy thanks to the on-screen instructions where you will hold down the volume down and power button for a few seconds.

Step 4. Once Dr.Fone - Screen Unlock (iOS) has detected your device in DFU Mode. You’ll be able to select which device you’re using and what firmware you want to be repaired; in this case, iOS 17/14.

Step 5. Once everything has been confirmed and you’re happy to continue, press the Unlock option. The program will do its thing, and when it’s done, the software will say you’re able to disconnect your Apple iPhone XS and use it without a lock screen!

That’s how easy Dr.Fone - Screen Unlock (iOS) makes the entire unlock process!

2.3 Restore an old backup from iTunes

Another key way that some users have found to unlock their device after an update is to restore their device to an older version, aiming to put your device back into a position where it didn’t have a lock screen.

It’s only possible to do this if you’ve backed up your iOS device in the past (which is why you’re encouraged to back up regularly), and it can all be done through the iTunes software on either your Mac or Windows computer. Here’s how it works;

Step 1. Ensure you’re running the latest version of iTunes and then connect your iOS device to your Mac or Windows computer using the official USB cable. This should automatically open the iTunes window.

Step 2. In iTunes, click the symbol representing your device and then click Summary. On this screen, you’ll be able to choose the Restore iPhone option at the top to begin the restoring process.

Step 3. Follow the onscreen instructions where you’ll choose which backup file you want to use before iTunes, then restores your device. When the software has completed the process, you’ll be able to disconnect your Apple iPhone XS and use it without a lock screen!

2.4 Restore in recovery mode

In some cases, restoring your device using just iTunes will not be good enough, and it won’t have the effect you’re looking for; in this case, restoring your device with no lock screen after an iOS 17/14 update.

If the above method of restoring your device via iTunes doesn’t work, or you haven’t got a backup file to load, you’ll need to restore your device using a move known as Recovery Mode, or DFU mode. This will hard reset your device and get it working to its full potential.

Here’s how to do it. (Note, the process will differ slightly depending on which model of iPhone you’re using).

Step 1. Press and hold the volume up button for about one second, and then switch and press the Volume Down button for the same amount of time. You can then hold the side button (on devices without a home button), and the following screen should appear after a few seconds.

Step 2. Now connect your Apple iPhone XS to your computer with iTunes and wait for iTunes to open. Make sure you’re running the latest version of iTunes before connecting up your device. Also, make sure you’re using the official USB cable for the most stability.

Step 3. iTunes should automatically detect that your device is in Recovery Mode and automatically restore your device to a default state without a lock screen. Wait until this process is completed before disconnecting your device and using it as normal.

2.5 Use Find My iPhone feature in iCloud

The fifth and final approach you can take to removing a lock screen from your recently updated iPhone or iPad when faced with the iOS 17/14 glitch is taking advantage of the integrated Apple technology and features are known as Find My iPhone.

While this feature originally allows you to literally find your Apple iPhone XS in the situation where it’s lost and offers many other security features to help ensure your device and data don’t fall into the wrong hands, you can also use it to remove your device unwanted lock screen.

Of course, this will only work if the Find My iPhone features have been enabled in the past, so make sure you’re using it to get it to work. Here’s how to use the feature to get your phone access back.

Step 1. From your computer, iPad, tablet, or mobile web browser, head over to iCloud.com and log into your iCloud account using the login in button at the top of the screen.

Step 2. Once signed in, scroll down the menu of features and select the Find iPhone feature. Click on the All Devices option at the top.

Step 3. From the list of devices connected to your account, click the Apple iPhone XS device name with the locked screen and then click the Erase option. This will clear everything from your device, much like the process we’ve spoken about in the methods above.

Leave the Apple iPhone XS device to erase, and once completed, you’ll be able to pick up and use your phone as normal without a lock screen. You should also now be able to update to iOS 17/14 without any problems!

Summary

And there you go, the five key ways you need to know when it comes to removing an unwanted lock screen from your iOS device after an iOS 17/14 update. We highly recommend the Dr.Fone - Screen Unlock (iOS) since the software makes the whole process incredibly easy, especially when managing any problems you may have on your iOS device!
