All versions seem to be working again, without re-installing or re-downloading 🤷♂️.
Some more weirdness.
- Main device (iPhone 16 pro, ios 18.x): 7.42 suddenly started working again without reinstall.
- Updated backup device (iPhone 12, ios 17.x) to 7.47, and it works.
- Updated main device to 7.47, and it crashes again. (Tried twice).
- Rolled back main device to 7.42, and it works.
So to summarize, I've got 7.42 working on iPhone 16 with ios 18, and 7.47 working on iPhone 12 with ios 17, but 7.47 won't work on my main setup.
Updated my backup device to ios 18.x and 7.47 is crashing there now.
Still not sure what's going on but it seems like the combination of latest versions ios 18.x + 7.47 causes the crashing.
With either of them on an older version (ios 17.x + 7.47, or ios 18.x + 7.42), I've been able to get it to work on at least one of my phones (iPhone 12, iPhone 16 pro).
All was done using sideloadly with same AppleId as the phones.
I can send you the copy of 7.42 I have if you'd like to try it; how would you suggest I do so though, for a 129MB file?
