Checkra1n Activation Lock
Danisa Southmayd
Starting with iOS 11.4.1, if you use USB accessories with your iPhone, iPad, or iPod touch, or if you connect your device to a Mac or PC, you might need to unlock your device for it to recognize and use the accessory. Your accessory then remains connected, even if your device is subsequently locked.
There were some notable improvements to this mode since then in both iOS 12 and 13. Currently, the major problem for the forensic expert is this: under certain circumstances (after a period of time, or if the emergency S.O.S. mode has been activated), the Lightning port is disabled on the device, and you cannot connect to the iPhone at all.
Whether the device is locked or not, you can still extract some information from it even without breaking the passcode. We have introduced BFU data extraction with the help of checkra1n back in November last year, see iOS Device Acquisition with checkra1n Jailbreak. What about the USB restrictions? See A word on USB restricted mode and pairing chapter at the link above. checkra1n is installed from the DFU (Device Firmware Update) mode that is always accessible even if the restricted mode has been activated for any reason. Moreover, old versions of checkra1n (that were available at the time), USB restrictions were turned off once jailbreak was installed.
The situation had changed in the later builds of chechra1n, see the DFU and USB Restricted Mode chapter in BFU Extraction: Forensic Analysis of Locked and Disabled iPhones. While you can still use the older build of checkra1n 0.9.5, that older build may not support the latest iOS versions (currently iOS 13.6). The solution, however, has been found: use a third-party tool that turns the USB restrictions off through the diagnostics mode, see Working Around the iPhone USB Restricted Mode. This extra step was never obvious and rather complicated, but at least it was there.
With checkra1n 0.10.2 (currently the latest version), the game has changed again. Whether USB restrictions are activated or not before you turned the device into the DFU mode, the device will be available after the reboot over the USB cable, and you can perform the extraction with Elcomsoft iOS Forensic Toolkit (do not forget the port number is 44 instead of common 22). Due to the nature of BFU extraction, do not expect too much of the keychain though. Speaking of the file system, not that much data is available either, but some notable evidence still can be found. The available bits and pieces include the account information, several system files, logs, message attachments, third-party app data, etc. If the device is locked with an unknown passcode, this is much better than nothing.
Second, if you want to use checkra1n in the BFU mode (when the passcode is not known) and USB restrictions have been activated, it is not enough just to fire checkra1n an follow the instructions, as the program simply will not see the device connected. You have to do one of the following manually:
We recommend the latter although it is a little bit more tricky; by our experience, this method has better success rate (while that may sound strange, as the program is course the same). I bet you will spend may be half an hour at the first time (if you did not do that before, and especially if you are not very familiar with macOS, command-line tools and DFU mode), but then will do that at the blink of an eye.
checkra1n works just fine with the latest versions of iOS, including iOS 12.4.8 for the iPhone 5s and iPhone 6, and iOS 13.6 on the iPhone 6s and later, both released just a couple of days ago. We have verified that on several test devices we have in our lab. Just remember that the last model supported by checkra1n is the iPhone X. For iPhone Xr, iPhone Xs and iPhone 11 devices, BFU acquisition is not possible at all.
Do you know the passcode (or the device is not locked at all) and want to perform the keychain and file system extraction? We got you covered in more than one way. Below is the updated compatibility chart. Interestingly, iOS 12.4.8 does not fix several known vulnerabilities, and apart from checkra1n, you have other options available. You can use our agent-based extraction method (recommended, as it is a forensically sound and safe to the device). Alternatively, you can install the latest version of RootlessJB4. RootlessJB4 is not completely stable as of yet, but still worth trying if you also need to extract the keychain without installing checkra1n, as our agent cannot access the keychain for iOS 12.3 through 12.4.8 (only file system extraction is available for these iOS versions).
Extract critical evidence from Apple iOS devices in real time. Gain access to phone secrets including passwords and encryption keys, and decrypt the file system image with or without the original passcode. Physical and logical acquisition options for all 64-bit devices running all versions of iOS.
Looking for a reliable method to Checkra1n iCloud bypass on your locked iPhone or iPad? Checkra1n is your go-to solution! Not only does it allow BFU acquisition of locked devices with unknown passcodes, but it's also a trusted and user-friendly tool that offers exceptional performance and stability.
The answer is Yes! Apple introduced the Activation Lock feature in iOS 12.3 to prevent stolen. While it is beneficial for security purposes, it can be a hassle for individuals who have forgotten their iCloud password.
The Checkrain iCloud Bypass is a tool that can help to circumvent the iCloud Activation Lock on Apple devices running iOS 12.3 or later. It may be beneficial for those who have forgotten their iCloud login information and cannot access their devices.
One of the best ways to bypass iCloud Activation Lock, particularly for iOS 16 devices, is by using Tenorshare 4MeKey. It is software that can bypass the Activation Lock on iOS devices and remove Apple IDs that are already logged in.
This software is easy to use and compatible with a wide range of iOS devices, including the latest models. By removing the Activation Lock, you can access your device without any restrictions or limitations.
After downloading and installing Tenorshare 4MeKey (Win or Mac) on your computer, you will be directed to the "Remove iCloud Activation Lock" interface. Before proceeding to unlock your iCloud account, keep in mind that the software will jailbreak your device, which carries the risk of potentially bricking it.
Once your iOS device is successfully connected to your computer, the jailbreak tool will immediately start downloading. Click on "Start Jailbreak", and the tool will begin to jailbreak your iPhone/iPad/iPod touch. Follow the step-by-step guide provided by the tool to complete the jailbreak process.
Once the jailbreak is complete, you'll need to verify your device information before proceeding to bypass the iCloud activation lock. It's important to note that after bypassing the lock, certain features such as phone calls, cellular service, and iCloud will not be available on the device with your new Apple ID.
In conclusion, both Tenorshare 4MeKey and Checkra1n are reliable tools for bypassing iCloud activation lock on iOS devices. While Tenorshare 4MeKey is a cookie-friendly solution, Checkra1n iCloud bypass requires certain code knowledge for its users.
Before if your phone was locked and you lost it, it was unusable unless the person could unlock it with the code. But now if you lose your iPhone up to iPhone Ex, it can be unlocked. And all your data on the phone, including those compromising photos, will be available to the finder as well! Be warned.
Well the question that I have, is that I was under the impression that the device was encrypted at rest. I assumed if you had a password on it, you needed to provide that password to get at the filesystem. This attack seems to make a mockery of that assumption.
I know that photos are not because you can access them from your PC even with the phone locked.
Also using a tool like iTools4 you can access, install apps, delete messages, books, photos and other data even with the activation lock on.
Thanks to the CheckM8 Tool, removing Activation Lock on iPhones has become extremely easy. The Checkm8 exploit used in the Checkra1n Jailbreak has been leveraged to develop the iCloud Removal Tool, which forms the core of the CheckM8 Tool.
It is not necessary to know the iCloud password as the program can bypass the activation step on a locked iPhone.
You can use the instant iCloud Bypass service to remove the Activation Lock screen on iPhone 5s up to X models and on iPads equipped with A5 - A11 CPUs.
If you need to bypass iCloud on a device with an A12+ Bionic Apple CPU (including models such as iPhone XR, XS, XS Max, iPhone 11 series, iPhone 12 series, and iPhone 13 series), please note that this is not an instant service.
After checking the device for compatibility using our software and placing your order, you will need to wait for the order processing result, which can take from 12 up to 72 hours. Usually, the response is received in less than 24 hours.
Once your iPhone is unlocked, you can use it like you normally would - make calls to your loved ones, use your Apple ID, listen to your favorite music, browse the internet, and play your preferred games. All the limitations will be removed!
The iCloud Bypass refers to a procedure that allows users to skip the Activation Lock on their iPhone or iPad. In essence, the bypass enables the device to bypass the activation step and recognize that it has already been activated.
It's important to note that if you attempt to open an app by an identified developer that isn't registered with Apple, a warning message will appear, but this doesn't necessarily indicate that there's an issue with the app.
To proceed with the process, you need to connect your iPhone or iPad to your Mac or Windows PC using a USB cable. If your Mac has only a Thunderbolt port, you will need to use a USB to Type-C adapter, otherwise, you may encounter an error (-20) with CheckRa1n.
