如果您发现自己需要从具有比目标设备更新版本的iOS的设备恢复备份,则需要注意,如果不进行一些调整,就无法将较新的备份恢复到降级的iOS设备。如果你没有尝试,你会看到这样的信息:

iTunes无法恢复iPhone“Renate的iPhone”,因为备份已损坏或与正在恢复的iPhone不兼容。

尝试将iOS Beta备份还原到旧版本的iOS

那你有什么选择呢?嗯,有两个:

  1. 修补备份以使其与早期版本的iOS兼容,或者

  2. 从iTunes或iCloud备份中提取所需数据,然后导入

我们将介绍下面的第一种技术以及备份恢复指南如何涵盖第二种技术。

如何修补降级的iOS备份版本

修补iOS降级的备份非常简单,尽管不可能在任何版本之间移动。我们已经强调了我们已经测试过的版本降级,并且知道它们正在下面工作。

第1步。 修改之前,请获取您的iOS备份副本。

第2步。 打开备份的根文件夹中的Info.plist文件。

您可以使用任何简单的文本编辑器打开此文件。

第3步。 搜索Product Version ,您将找到如下所示的部分。

<key>Product Type</key>
<string>iPhone10,6</string>
<key>Product Version</key>
<string>12.3.2</string>
<key>Serial Number</key>
<string>C8QH6T96DPNG</string>

第4步。 更改Product Version值并保存文件。

例如,从12.1.312.112.0并保存文件。

哪些备份版本可以降级?

可能是其他版本降级工作,但这些是我们测试并确认工作的那些。这种技术依赖于某些版本之间的底层存储格式几乎没有什么不同。如果您在其他版本上取得了成功,请在下面的评论中告知我们的读者。

from 6s 14.1 to 6Plus 12.4.9

Done!

Woohoo!

Worked on with iphone SE (first gen) 14.2 --> iphone SE (first gen) 13.6, except for sms/imessages. Those were subsequently recovered by turning on icloud on both devices, turning sync messages to on, and giving the devices time to sync/download the messages (this takes several hours).

Thank you!!

Successful from : 13.5.1 (iPhone X) to 12.4.6 (iPhone 6) Thanks a lot

I KNEW it. There had to be a way. THANK YOU, thank you THANK YOU.

Don't know how I stumbled on to this page, but grateful beyond words, that I did. Used option #1 Worked like a champ. iphone 5se destroyed. Picked up a 5s for next to nothing. OS on the 5se was 13.5 The 5s only goes up to 12.4.7 I Tunes or I Cloud wouldn't restore the backup. Called Apple support, and they didn't have a clue. Thanks again. Really worked.

I'm trying to restore my backup from iphone 7plus(iOS 13.3.1) to iPhone 8(iOS 13.4.1). I was getting the error message while progressing the restoring process. The message is 'iTunes could not restore the iPhone "iPhone" because the backup was corrupt.'

I changed the Product Version in the Info.plist file in the root folder to 13.4.1 from 13.3.1. But still the same error popping up!

Please help me to get my backup :(

Hi Sreekanth. Changing the version like this won't help if the backup is corrupt. We've got a guide for fixing corrupt backups here. If you get stuck, drop us a note!
