Un-jailbreak iPhone without updating iOS?
I have a jailbroken iPhone 6s, running iOS 9.3.3.
An "Erase all content and settings" will reset the phone, but will not "un-jailbreak" the phone. I know a factory restore will completely wipe the phone and update the iOS to the latest available (and hence remove the jalbreak), but I want to keep the iPhone on iOS 9.
Is there a way I can un-jailbreak my phone, without having to update the software?
You can use Cydia Eraser by Saurik to completely wipe and restore your device to stock iOS without updating.
