How to update to iOS 14.3 from iOS 11.3-14.2.1 without SHSH Blobs

For a period of one to ninety days, Apple permits supervised corporate devices to postpone updates like iOS 14.3 update. This feature’s purpose is to postpone firmware updates so that your business can test them before allowing its employees to do so. This function, however, has a very obvious flaw. An MDM (mobile device management) profile is not necessary to delay updates. It suffices to install a phoney profile on a supervised device where iOS 14.3 download is done.

For those who are unaware, a supervised gadget is one that gives a company more control over how it is configured.

How to spoof your device?

There are two techniques to fake who is in charge of your device:

  • Non-jailbroken devices: iMazing or Apple Configurator 2.
  • MyBloXXX devices with jailbreaks

For those who missed the opportunity to upgrade to iOS/iPadOS 14 or above, this loophole is a blessing. Now that the iOS 14.3 update is the most recent operating system that can be jailbroken, you can jump right to it as it is very easy to jailbreak iOS 14.3 with some steps.

What does it offer?

This offers two advantages.

  • First off, upgrading from an older operating system like iOS 12 or 13 to iOS 14 is simple. You have the option to upgrade to a more recent and reliable version if you are currently on iOS 14.
  • Second, you may jailbreak iOS 14.3 on your Apple device using unc0ver or taurine.

Keep in mind that this approach has an expiration date and is not intended to work “forever.” Before iOS/iPadOS 14.4 reaches its 90-day mark, you must complete it. It means to downgrade iOS 14.4 to 14.3. As a result, after April 26, 2021, this approach will no longer be functional for on-device OTA to iOS 14.3 update.

Precautions:

  • On devices with the A14 system-on-chip, this procedure DOES NOT WORK or iOS 14.3 not installing Installing the profile results in a personalization error for A14 devices.
  • The upgrade may fail if your SEP version is higher than that of your target firmware. You will see the “Unable to check for update after jailbreak” problem because OTA is unable to downgrade the SEP.
  • This solution most likely won’t work for you if you upgraded to iOS 14.3 update using FutureRestore after January 26, 2021.

Conclusion

Unc0ver and Taurine jailbreaks for iOS 14 – iOS 14.3 are available for all iPhones and iPads. The issue is that Apple is no longer signing iOS 14.3 update, so you are stuck with it if your jailbroken iPhone is running an older version of iOS. You could always update your iPhone to iOS 14.4.2, but doing so would prevent you to jailbreak iOS 14.3. However, if your iPhone is running iOS 14.2.1 or before, a new technique has been uncovered that will enable you to upgrade it to iOs 14.3 update. The technique is compatible with iOS 13-powered iPhones and iPads. Basically, you can update 14.3 iOS and still jailbreak your iPhone or iPad if it is running iOS 13 – iOS 13.7 or iOS 14 – iOS 14.2.1.
