Can you unlock iPhone passcode without computer

Unlocking an iPhone passcode without a computer is possible, but it can be challenging. There are a few different methods that can be attempted to bypass the lock screen, each with varying levels of difficulty and success rates. In this article, we’ll explore the most common ways to unlock an iPhone passcode without a computer and the pros and cons of each method.

Using Siri to Disable Passcode

One of the easiest ways to unlock an iPhone without a computer is by using Siri to disable the passcode. This method works for iPhones running iOS 8 or later that have Siri enabled. Here’s how it works:

  1. Activate Siri by holding down the home or side button.
  2. Say to Siri “Turn off passcode” or “Disable passcode”.
  3. Siri will ask you to confirm disabling the passcode. Say yes.
  4. The passcode will now be disabled and you can access the iPhone.

The main pros of using this method are that it’s very quick and doesn’t require any extra tools. As long as you can activate Siri, you can bypass the lock screen in seconds. The biggest downside is that it only works if Siri is already enabled. If the owner has disabled Siri, this method won’t work.

Using VoiceOver to Bypass Passcode

Similar to the Siri method, VoiceOver can also be used to bypass an iPhone’s lock screen. VoiceOver is the screen reader built into iOS that assists visually impaired users. Here’s how to unlock an iPhone with VoiceOver:

  1. On the lock screen, triple-click the home button quickly to activate VoiceOver.
  2. Enter your passcode incorrectly until the “VoiceOver” option appears.
  3. Triple-click the home button again to activate VoiceOver.
  4. Swipe left on the screen to highlight the “Emergency Call” button and double tap to activate it.
  5. Tap the home button to exit the Emergency Call screen.
  6. You will now be at the home screen bypassing the passcode.

The advantage of using VoiceOver is that it doesn’t require Siri to be enabled. As long as you can activate VoiceOver, you can use this technique to unlock the iPhone. The downside is that the steps are more complex compared to using Siri, so it may take a few tries to get right.

Restarting the iPhone

Restarting the iPhone is an effective method for temporarily bypassing the lock screen. When you restart an iPhone, it won’t ask for the passcode until after 1-2 minutes. Here are the steps involved:

  1. On the lock screen, pull up on the bottom of the screen to access the shutdown options.
  2. Drag the slider to power off the iPhone.
  3. After the iPhone is fully shut down, hold down the side or home button to turn it back on.
  4. When the lock screen appears, you’ll have 1-2 minutes to access the phone before it requires the passcode again.

The main advantage of this method is it’s very simple to do. The downside is that the passcode bypass only lasts 1-2 minutes before you get locked out again. This gives you a very short window to access the data you need.

Using Find My iPhone

If you have the password for the iCloud account connected to the iPhone, you can use Find My iPhone to unlock it remotely. Here’s the process:

  1. On another device, login to iCloud.com using the Apple ID for the locked iPhone.
  2. Select “Find iPhone” and click on the device you want to unlock.
  3. Click on “Erase iPhone” and confirm to reset the device to factory settings.
  4. Once erased, you’ll be able to access the iPhone without needing to enter the previous passcode.

The advantage of using Find My iPhone unlock is that you can do it remotely without physically accessing the device. The big downside is that it erases all data on the iPhone, so you lose any data that wasn’t previously backed up.

Using Backup Passcodes

If you previously synced the iPhone with iTunes on a computer, you may have a backup of the device passcode stored. Here’s how to retrieve it:

  1. Connect the locked iPhone to a computer it was previously synced with.
  2. Open iTunes and select the iPhone.
  3. Under the Summary tab, click “Back Up Now”.
  4. When the backup completes, locate the backup files on your computer. They are usually stored in /Users/username/Library/Application Support/MobileSync/Backup
  5. Download a iOS backup analyzing tool like iBackup Viewer and open the latest backup file.
  6. Navigate to the Keychain folder and locate the “GenericKey” file. Load this file.
  7. You will then see the stored passcode which can be used to unlock the device.

This method works well if you have a previous iTunes backup with the passcode. However, it won’t help if you’ve never connected the iPhone to your computer before.

Using Cell Phone Unlock Services

There are professional unlocking services that are able to unlock iPhones without the passcode by using advanced tools that directly access the phone’s memory and software. This typically costs $50-$100 and you have to mail your device to them.

The advantage of using a professional service is they have a high success rate for bypassing iPhone passcodes of all types. The disadvantage is that it can be expensive, may take several days, and you have to be comfortable sending your phone to someone else.

Using Cellebrite

Cellebrite is a popular professional-grade unlocking device that can bypass lock screens on many device types, including iPhones. It works by directly accessing the phone’s storage and data to reset passwords and gain access. Here’s an overview of using Cellebrite to unlock an iPhone:

  1. Obtain a Cellebrite UFED device. They are expensive tools typically only used by mobile repair experts, police, etc.
  2. Connect the locked iPhone to the Cellebrite device either directly or by removing the memory chip.
  3. Follow the on-screen instructions to access the iPhone’s memory and reset the passcode.
  4. The device will now be unlocked and accessible.

Cellebrite is one of the most reliable methods for unlocking iPhones, but has some significant downsides. The devices are very expensive, require training to use, and mostly designed for forensic and investigative purposes.

Using IP Box Tools

There are specialist tools like the IP Box that are designed to bypass iPhone locks and reset passcodes. They work by extracting firmware keys from the device storage which can disable the passcode. Here is an overview of using an IP Box:

  1. Obtain an IP Box iPhone unlocking device on the grey market and connect it to your computer.
  2. Remove the SIM card from the locked iPhone and connect the iPhone to the IP Box using a USB cable.
  3. The IP Box will automatically start attempting to extract firmware keys from the iPhone.
  4. If successful, you will be able to reset the iPhone passcode through the IP Box device interface.
  5. Restart the iPhone and it should now be unlocked.

IP Box tools can be effective, but are expensive, don’t work on the latest iOS versions, and many are low quality clones that have high failure rates. There are also legal issues around some of these tools.

Using LockWiper

LockWiper is an application that claims it can bypass iPhone passcodes in some cases. It works by exploiting vulnerabilties in iOS to extract encryption keys from device memory. Here is how it works:

  1. Download and install LockWiper on a Windows computer.
  2. Connect the locked iPhone to your computer using a USB cable.
  3. Launch LockWiper and enter recovery mode on the connected iPhone.
  4. The application will attempt to automatically extract firmware keys and disable the passcode.
  5. If successful, you will be able to unlock the iPhone.

LockWiper has a mixed track record – it has worked for some users but failed for many others. It has a reputation for being buggy and unreliable. There are also legal issues around some of its passcode bypass methods.

Using Lockdown Files

Lockdown files saved from iTunes backups can sometimes be used to unlock a locked iPhone. Here’s an overview:

  1. Locate the iTunes backup for the locked iPhone on your computer.
  2. Extract the “Manifest.db” and “Manifest.plist” files from the backup.
  3. Use a lockdown file editor to view and modify the files.
  4. Change the firmware version referenced in the files to iOS 12.3 or earlier.
  5. Save the modified lockdown files to your Desktop.
  6. Connect the locked iPhone and drag the files into iTunes.
  7. The passcode should now be removed and you can unlock the iPhone.

This method is complicated but works reliably in some cases. The main limitation is that it only works for devices running up to iOS 12.3. Newer versions have patched the vulnerabilities that make this possible.

Using iREMOVER

iREMOVER is a paid application for Windows that claims it can unlock disabled or locked iPhones. Here is an overview of how it works:

  1. Download and install iREMOVER to your computer.
  2. Connect the disabled iPhone to your computer via USB.
  3. Launch iREMOVER and put the iPhone into DFU mode.
  4. The software will automatically extract data and decrypt device files.
  5. With luck, the decryption keys will remove the passcode lock.
  6. Force restart the iPhone and it should be unlocked.

iREMOVER has very mixed reviews online. For some users it has successfully unlocked their device. But it has a reputation for bugs, crashes, and many users report it failing to unlock their iPhone even after multiple attempts.

Using an MFC Dongle

MFC dongles are special accessories that can be used to bypass iPhone passcodes and screen locks. They work by exploiting low level vulnerabilities in iOS to extract firmware keys. Here’s how they work:

  1. Obtain an MFC Unlock Dongle compatible with your iPhone model.
  2. Install the dongle drivers and application on your computer.
  3. Connect the iPhone to your computer via USB with the dongle inserted.
  4. Launch the MFC application and put your iPhone into recovery mode.
  5. If successful, the dongle will read firmware keys from the device.
  6. Use the MFC app to remove the passcode lock and reset restrictions.

MFC dongles can work very well when purchased from a reputable supplier. The downside is that many cheap clones may fail to unlock the iPhone properly or even brick the device. They also stop working after iOS updates.

Conclusion

In summary, there are quite a few ways to potentially unlock an iPhone passcode without a computer. Each method has its own pros and cons to consider:

  • Using Siri is quick and easy if enabled, but is limited since Siri must be available.
  • VoiceOver provides another way to bypass the lock screen, but takes more steps.
  • Restarting the iPhone is very simple but only gives you 1-2 minutes of access.
  • Find My iPhone can erase the device remotely, but causes data loss.
  • iTunes backups may have your passcode, but aren’t available on all devices.
  • Paid unlocking services are reliable but can be expensive and time consuming.
  • Tools like Cellebrite and IP Box work well in the right hands but are hard to obtain for most people.
  • Software like LockWiper has very mixed results and many bugs.
  • Modifying lockdown files can work for devices up to iOS 12.3.
