<div>It's standard procedure for Apple to stop signing iOS versions around a week at most after the release of a newer version. You should never upgrade with the expectation that you can downgrade later - and I'd argue that people shouldn't be downgrading because they're just re-introducing known security issues. </div>
<div><br></div>
<div>Stopping signing an obsoleted and known vulnerable version of an operating system that gets free upgrades hardly qualifies for calling people "bastards" IMO...</div>

<br>> my 9.0.0 -> 9.0.1 upgrade failed, they then released 9.0.2 but I had already reverted to 8.4.1 (took a day to do a full iCloud restore) so going to 9.0.2 was logical and worked from 8.4.1.
<br>>
<br>> Apple are no longer signing 8.4.1 so there is no option to downgrade so you have to hope "9.0.0 to 9.0.2” or "9.0.1 to 9.0.2” work as these are the only routes if you are already on 9.0.0.
<br>>
<br>> To be clear, it is 9.0.0 that has the "slide to upgrade” problem, but it didn’t surface with me until the 9.0.1 upgrade was attempted.

<br>>>> This sounds all too painful and not something i’d like to go through following the “slide to upgrade” issues with IOS9. I had to revert to IOS8, restore from iCloud and then upgrade to 9.0.2. That’s not how to do minor upgrades Apple!
