Updating your iphone

This is due to modifications that are made by jailbreak apps/tweaks that won’t be undone simply by using ‘Erase all content and settings’ in the settings app. Prometheus (AKA futurerestore) is a tool created by tihmstar which allows you to restore to unsigned i OS versions as long as you have SHSH2 blobs saved for them.

It does, however, require you to already be jailbroken, or using an exploit to set some values before you will be able to use it.

This method also requires that you have valid SHSH2 blobs saved for i OS 11.1.2.

If you do not have these saved already, it is too late to save them as Apple no longer signs i OS 11.1.2.

This does, unfortunately, mean you won’t be able to use it to downgrade i OS 11.2 or above to i OS 11.1.2 (at the moment).

If you are currently running i OS 10 jailbroken, and want to update to i OS 11 to jailbreak, you can follow the guide linked here.

There have been numerous reports from owners of the i Phone 6 or i Phone 6s Plus, stating that their battery percentage icon is no longer updated.

Meaning, these i Phone users have no idea what battery percentage their device is really at.

While we’re not exactly sure as to what causes the problem, but there is an easy solution that does work.

You should always save SHSH2 blobs for every i OS version.

It is also worth mentioning that if you do not have SHSH2 blobs for i OS 11.1.2, you will not be able to use someone else’s, as these blobs are specific to each device.

Simply, toggle Set Automatically ON/OFF multiple times, or switch time zones as well.

If these steps do not work, well, here is what Apple says, “If this happens again and you didn’t change the time or time zone on your device, contact Apple Support.
