Having trouble installing the checkra1n jailbreak? If you do it right, you achieve a nearly 100% success rate. We have collected the most important information on how to install and troubleshoot the checkra1n jailbreak. While you are doing this process, the iDevice has to face a number of issues, simply the iOS 16.1 jailbreak process is a risky process for the iDevice. The iCloud Bypass method with the IMEI number process doesn’t need any jailbreak process to start the iCloud Bypass process.
By following these advises, you will be able to jailbreak like a pro, whether you just want to research your own device or perform the file system and keychain acquisition. If you do not know if iCloud is lock you can purchase our Check. Unlock Carriers use the procedure of the IMEI Number UnlockCompatible on iOS 16.1 versions
Whether to install a jailbreak or not is always your decision. If you are about to extract the device, there might be multiple options at your disposal. There might be other jailbreaks available such as the unc0ver jailbreak; yet another one (Odyssey) is coming. iCloud Lock problems can happen to anyone who owns an Apple device. The main reason behind this is that there are many users who buy used iPhones from eBay or second-hand retailers.
Normally, the seller should provide the Apple ID and password along with the device, but there are many cases where they did not. And always when you purchase an old iPhone, it should be your priority to ask for the Apple ID credentials if you wish to avoid iCloud activation lock problems.
The checkra1n iOS 16.1 & unc0ver: How Would You Like to Jailbreak Today can help you decide.
The main advantage of checkra1n is the support for the latest versions of iOS that no other jailbreaks are available for. For the forensic community, checkra1n is the only jailbreak allowing the BFU (Before First Unlock) acquisition of locked devices with an unknown passcode.
Finally, checkra1n does not require you to sign the jailbreak IPA file (using AltStore or the Developer Account at Apple). If you currently have iPhone which is iCloud lock then you have no choice but to seek an unlock iCloud iPhone solution. Fortunately, the iCloud lock problem can be easily resolve.
Compatibility & CLI mode
checkr1n is compatible with the iPhone 5s through iPhone X with iPhone 14 Pro Max, iPhone 14, iPhone 13, iPhone 13 Mini, iPhone 13 Pro Max, iPhone 13 Max, iPhone 12 Mini, iPhone 12 Pro Max, iPhone SE 2, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS Max, iPhone XS, iPhone X, iPhone XR as well many iPad models and even Apple TV 4 (Apple TV HD) and Apple TV 4K. Supported iOS versions range from iOS 16.1 to 16.2 Beta.
At this point, there are two verify and legitimate methods that can help you get the job done right. The first one is a bit tricky because it requires you to ask Apple directly to remove the iCloud lock. However, the trick is that you will be ask to provide ownership proof. And of course, if you have bought a used iPhone from a second-hand retailer this will be next to impossible to do. To use checkra1n with iOS versions that are not officially support, enable the “Allow unrest versions” option.
We tried checkra1n on iOS 16.1 to 16.2 Beta (which is actually the “Gold Master” release) and it works just fine. What about the older versions (iOS 16.2.1 and below)? Do not ever bother trying. Furthermore, even if you have ownership proof this iCloud Unlock method can be really possible. The second method for unlocking iCloud accounts is that of Unlock Carriers. Our method is simple, legal and reliable, through the IMEI number of your iPhone or iPad, we will unlock your iCloud account.
We also recommit using CLI mode over GUI, it is found to be more reliable. Also, if you perform BFU acquisition of the device that is locked in USB restricted mode, this is the only way to go. Every single feature works perfectly 100%, Fix Push Notifications, FaceTime and iMessage. Once you unlock your iPhone you will get a notification on your device. All you have to do is connect your iPhone to iTunes to complete the unlock.
checkra1n Installation Platform
If you have Windows and macOS computers at your disposal, we recommend using macOS for installing checkra1n. If you don’t, there is a version for Linux.
You may be able to use an emulator or a bootable flash (e.g. with Ra1nUSB/Bootrain/ra1nstorm) if a Windows computer is all that you have.
There is also a Raspberry Pi port, but here is what developers say:
The exploit may not work as reliably on some devices, such as the Raspberry Pi Zero and Raspberry Pi 3.
So again, to save the time, use the native macOS version on any Mac computer. We have not tested it on Big Sur yet, but it works just fine on Catalina.
Cables & connection
First of all, always use the standard Lightning to USB Cable (the Type-A cable), but not the USB-C one. Here is why (from the checkra1n Web site).
Lightning-to-USB-C cables are trouble: specifically, some of them cannot be used to enter DFU mode and there is nothing we can do about that.
This includes Apple’s own USB-C cables, as well as some 3rd party ones – other 3rd party ones have shown to do work though. If your cable turns out to not work, we recommend using a USB-A cable instead, if necessary in combination with a USB-A-to-C adapter.
The BootROM will only enter DFU if it detects USB voltage, which boils down to checking whether a certain pin is asserted from the Tristar chip.
The Tristar does this based on the cable’s accessory ID, and apparently USB-A and USB-C cables have different accessory IDs, and the one of the USB-C cables makes the Tristar not assert the USB voltage pin.
Also, do not use any USB hubs (only USB-C to USB-A adapter if needed).
Other tips iCloud Bypass iOS 16.1
The other thing that dramatically affects the checkra1n success rate is the battery charge level. Make sure that the device is not in the Low Power Mode, and charge your device well over 20%.
Another important thing recommended by checkra1n developers is:
When trying to jailbreak multiple devices, only the first attempt will succeed. Workaround: relaunch checkra1n after every jailbreak attempt.
In fact you may also need to restart your Mac computer. Looks like the USB driver (or some other system component on the computer) has a problem with checkra1n, and restarting the computer does help. Also, re-connect the device and enter it into the DFU mode again.
If you still have a problem, submit it to the checkra1n issue tracker (providing as much details as possible, but please search if a solution already exists to avoid duplicates.
The future Jailbreak iOS 16.1
Will checkra1n work with future versions of iOS (including iOS 16.1)? In case if you are curious, we have tested the latest version with iOS 16.2 on several devices from the iPhone 6s to iPhone X, and it does not work yet (though we have a report from one partner saying that he was able to install it on one device).
Most probably, it can be adapt to work with future versions of iOS, but the devil is in the detail. Rumors say that Apple had make some improvements targeting BFU acquisition of iPhone 7, iPhone 8 and iPhone X – iPhone 11, 12 and 13 with 14 Pro Max devices (the iPhone 6s is not affected for some reason).
However, if you know the screen lock passcode, you will be able to install checkra1n on these devices, but only after removing the passcode. Note that removing the screen lock passcode has many negative consequences regarding the device contents and iCloud access.
