Another option is that whatever bug cellebrite was exploiting to extract data from iPhones in AFU mode is now subtly not working, leading to unexpected reboots when attempting extraction.
I very much doubt it. Far more likely to be a memory leak in the baseband which is exposed when the devices are unable to talk to the cellular network for a period of time.
Ya, I'm guessing these cops don't have iPhones because if they did they would know that iOS is just buggy. I mean, the last time I restarted my iPhone before iOS 18 was when I installed the last iOS 17 patch. Since installing iOS 18 I've had to restart it twice because it stopped responding.
This is fascinating, such that I went looking for more information on this phenomenon and found an interesting preprint regarding the polymorphism of ritonavir suggesting that specific milling processes are able to reliably produce each form.
At least I think that's what it says, I'm definitely not a chemist!
