An important courtesy reminder for the jailbreak community: Sunday, March 13th at 00:00 P.M. UTC (7:00 P.M. EST) is the hard deadline for using the DelayOTA method to upgrade to the unsigned iOS or iPadOS 15.1 or 15.1.1 firmware.
Because these versions are already unsigned, you can’t upgrade to them normally. DelayOTA grants a 90-day grace period post-unsigning with Supervised mode, and that’s what is set to expire at the aforementioned date and time.
For details about how you can use DelayOTA, you may refer to whichever of the guides below applies to you (depending on whether you are or aren’t jailbroken):
- Updating a NON-jailbroken device to unsigned firmware using DelayOTA
- Updating a jailbroken device to unsigned firmware using DelayOTA
With the release of an iOS & iPadOS 15.0-15.1.1-supported exploit, jailbreak developers have started investigating the feasibility of developing a jailbreak around it. This has left many prospective jailbreakers wondering if they should jump to the latest supported firmware.
While we can’t make this decision for you, here’s some advice:
- DelayOTA can’t downgrade your firmware, it can only upgrade it from an older version
- If you’re not already jailbroken, you may and should consider DelayOTA-ing to iOS or iPadOS 15.1.1
- If you’re already jailbroken on iOS or iPadOS 14, choose wisely. As a rule of thumb, we consider a jailbreak to be better than no jailbreak, so you may ultimately decide to stay where you are, but the final decision to gamble with the possibility of an iOs or iPadOS 15 jailbreak is up to you.
- If you have the proper SHSH blobs saved, then you needn’t rush because you can use futurerestore to upgrade to iOS or iPadOS 15.1 or 15.1.1 at any time.
- If you have an A9-A11 device (iPhone 6s to iPhone X), then you may or may not rush because the checkra1n jailbreak may eventually support your device regardless of which firmware it’s using. However, a different jailbreak may support iOS or iPadOS 15 on such a device first, so it’s a gamble that’s ultimately up to you.
With the above considerations aside, be sure to take advantage of the remaining hours to use DelayOTA to get in iOS or iPadOS 15.1 or 15.1.1 before it’s too late, unless you’ve decided not to.
Please note that some newer devices, especially those equipped with A14 chips, may not work when attempting DelayOTA. This is due to a problem commonly referred to as the ‘A14 Curse.’ These devices must instead use the futurerestore method, which requires saved SHSH blobs.
