Saurik releases Cydia Impactor to “unjailbreak” your iPhone without updating iOS

saurik, founder of Cydia, has released a powerful new tool called Cydia Impactor. It allows you to remove the jailbreak from your jailbroken device and return it to stock Apple iOS software without the need of restoring (updating) it.There are several tools such as iLEX RAT, a command line tool, and Semi-Restore, a desktop tool that allow you to restore your jailbroken device without losing the jailbreak. But as saurik points out, Cydia Impactor has a different objective. It is the first tool that allows you to remove the jailbreak so you don’t have to restore your iOS device. You can also do it right on the device, you don’t need a computer to do it.

The most notable thing about this tool is that it allows you to return to stock without needing to upgrade your device. Say, for example, you wanted to sell your iPhone, but wanted to retain its jailbreak-ability to increase resale value. Normally, if you wanted to perform a full system restore, you’d be forced to upgrade to the latest firmware, and thus lose your jailbreak. With Cydia Impacter, you can restore your device to stock without upgrading.

Cydia Impactor version 0.9.15 is currently in beta for iOS 8.3 and iOS 8.4 only. Keep in mind that before running this tool you should backup your data first via iCloud or iTunes. Cydia Impactor will remove all data, as that is what it’s designed to do.

saurik also has explained how the tool works:

Impactor uses the firmware archives provided by Apple for its “over the air” update feature. These files are ~2GB large, so Impactor goes to extreme lengths to minimize the amount of data it needs to download: most recoveries will require less than 10MB of transfer.
First, the update’s “bill of materials” is compared against the files on your device, generating a list of changes.
Then, all files on your device that have been modified or otherwise destroyed are downloaded directly from Apple.
In a series of carefully calculated file migrations, all new files are moved to the user partition, and all system data is moved back to the system partition.
Up until this point, the idea is that no changes to your system have been made that are “unsafe”: at any point, if Impactor fails/crashes or your device reboots, you can just run it again later.
Finally, all of the staged changes to the filesystem are “committed”, all user data is deleted, and iOS is told to run its “reset all content and settings”.
The idea is that this “critical window” lasts only the final few seconds of a process that lasts for multiple minutes.
(That said, I still highly recommend not at all “messing with” the app while it is running, and maybe if you have a lot of data this will take longer than I expect.)
When the device reboots, it will look as it did when you first turned it on; it will also no longer be “jailbroken”: if you want to jailbreak it, you will need to do so using a desktop jailbreaking tool.

Please note that Cydia Impactor is currently in beta and is available on Cydia. You should take a backup of your device using iTunes or iCloud before using it.

This tool works with all iOS devices except iPod Touch 6th generation… 

saurik, founding father of Cydia, has launched an impressive new device referred to as Cydia Impactor. It lets in you to get rid of the jailbreak from your jailbroken software and go back it to inventory Apple iOS device without the will of restoring (updating) it.There are a couple of equipment comparable to iLEX RAT, a command line device, and Semi-Restore, a pc device that permit you to repair your jailbroken tool without dropping the jailbreak. But as saurik issues out, Cydia Impactor has a special function. It is the primary device that permits you to dispose of the jailbreak so that you don’t have to repair your iOS software. You too can do it proper at the software, you don’t want a pc to do it.

The so much remarkable factor approximately this software is that it lets in you to go back to inventory without desiring to improve your software. Say, as an example, you sought after to promote your iPhone, however sought after to preserve its jailbreak-skill to building up resale worth. Normally, in the event you sought after to carry out a whole gadget repair, you’d be pressured to improve to the up to date firmware, and therefore lose your jailbreak. With Cydia Impacter, you'll be able to repair your software to inventory without upgrading.
Cydia Impactor model 0.9.15 is lately in beta for iOS 8.3 and iOS 8.4 handiest. Keep in thoughts that ahead of operating this device you will have to backup your knowledge first by means of iCloud or iTunes. Cydia Impactor will get rid of all knowledge, as that may be what it’s designed to do.

saurik additionally has explained how the device works:
Impactor makes use of the firmware records supplied through Apple for its “over the air” update function. These information are ~2GB massive, so Impactor is going to excessive lengths to reduce the volume of knowledge it wishes to obtain: so much recoveries would require not up to 10MB of switch.
First, the update’s “invoice of fabrics” is when compared towards the information on your software, producing an inventory of adjustments.
Then, all information on your tool which were changed or differently destroyed are downloaded right away from Apple.
In a chain of sparsely calculated record migrations, all new information are moved to the consumer partition, and all device knowledge is moved again to the device partition.
Up till this aspect, the theory is that no adjustments to your device were made which might be “dangerous”: at any aspect, if Impactor fails/crashes or your tool reboots, you'll be able to simply run it once more later.
Finally, all the staged adjustments to the filesystem are “dedicated”, all consumer knowledge is deleted, and iOS is informed to run its “reset all content material and settings”.
The concept is this “very important window” lasts best the general few seconds of a procedure that lasts for more than one mins.
(That stated, O nonetheless extremely suggest by no means “messing with” the app at the same time as it's operating, and perhaps when you've got a large number of knowledge this may increasingly take longer than A be expecting.)
When the software reboots, it is going to glance because it did while you first became it on; it's going to additionally now not be “jailbroken”: if you wish to have to jailbreak it, you'll want to achieve this the use of a computer jailbreaking device.
Please notice that Cydia Impactor is recently in beta and is to be had on Cydia. You will have to take a backup of your software the use of iTunes or iCloud prior to the use of it.

This software works with all iOS units except for iPod Touch sixth era...
