Confirmed! iOS 14.8.1 is closed, iOS 15.1 is 6 days away

1. Confirmed! iOS 14.8.1 is closed

Recently! Some netizens reported to me that when upgrading the iOS 14.8.1 system using the plug-in method with a lower version, the problem of "Unable to verify update" occurred. What happened? Please continue reading.

According to the feedback from netizens, use the following method:

• Supervision + description file (invalid)
• Flat brush + supervision + description file (invalid)
• Supervision + Dallas plugin + clean jailbreak (invalid)

The iOS 14.8.1 update package can be detected, but the update cannot be verified.

Regarding the problem of "Unable to verify update", it is very likely that Apple has turned off the delayed upgrade verification of iOS14.8.1OTA. After my test, I used iPhone 6S Plus and iPhone 11 Pro Max to upgrade to iOS 14.8.1 system test, and the problem of "Unable to verify update" still occurred.

If there is no new solution, it is certain that Apple has officially shut it down. Note! This does not mean that the iOS 14.8.1 system is particularly good, it just means that it is the only version that can be upgraded to the iOS14 system. Now there is no way to do it, and you can only upgrade to the iOS 15.1 system.

2. iOS 15.1 can be upgraded, 6 days left

Regarding the iOS 15.1 OTA delayed upgrade method, there are still 6 days left. If you want to upgrade, hurry up. Once you miss it, you will not be able to upgrade it.

OTA delayed upgrade method:

The method is very simple. You only need to turn on the supervision mode, install the delayed upgrade description file, and then open Settings-General-Software Update. If you really don’t understand, you can open the "OTA Delayed Upgrade" tutorial and follow the steps step by step. It is not difficult.

Attention! Some devices may not be able to detect the iOS 15.1 update package and can only detect iOS 15.1.1. If the iOS 15.1 update package cannot be detected, you can try to use the plug-in upgrade method. The operation method is still to turn on supervision + Dallas plug-in + clean jailbreak.

That’s about it. By the way, can you still upgrade to iOS 14.8.1 now?
