They exploited a bug, somehow, on old software and hadrware, an IPhone 6. Not an iphone 6s, or 7 , nor X. It also had a 4 digit passcode vs. 6 today, and 10 tries and the phone ERASES ITSELF.
You keep repeating stuff that isn’t relevant to the claim of an Apple designed backdoor, which was the original subject.
You are too dumb to stay on topic, and too dumb to tell the difference. I already told you that occasional bugs can be exploited, but they are hard to find, and very hard with current hardware and software, and Apple plugs tnem regulatly when tney are found/reported. That’s why there are thousands of iPhones in the hands of police in the country that cannot be accessed TODAY.
