iphone – iOS Caught in boot loop — What’s the largest file on the system which additionally occurs to brick the cellphone if deleted?


I recurrently optimize the file storage of my iPhone, (iOS 14.3, unc0ver), and this time round, I deleted a file I assumed was analogous with a Home windows cache file of a pair gigabytes that usually is recreated for those who delete it. I do not forget that the file title included the phrases “cache”, undescores, and “arm” or “arm64” amongst 2-4 different phrases. I need to say the file sort was .dll, however I really feel like there’s a nice likelihood that I’m simply misremembering this half. The file was the biggest file within the system by far with ca. 2.9 gigabytes.

As soon as deleted in Filza, I observed the cellphone continued working, and the app didn’t crash—this satisfied me that I deleted one thing seemingly analogous to the cache file on Home windows, or worst case state of affairs, one thing that’s not obligatory for operation — additionally supported by the truth that the modifying date was January 1, 2020 making me suppose it’s some information particles.

As soon as assured, I deleted the file from the trash in Filza—and, in fact, that was deadly. Minutes later I attempted to initialize an app that had not been operating earlier than the failure, and no it would not begin. I attempted once more with different apps to no avail.

I knew I can’t retrieve the file, and I nonetheless was pretty convcinced that even when it was an operative cache file like on Home windows, it might symply be recreated from the OS on reboot.

And that is since when the cellphone has been in bootloop for hours by the point I’m posting this.
