Hello everyone, Lin Fei to answer the above questions, ios 11 airdrop how to use, ios 1103 many people do not know, now let's take a look!

IPhone5S iOS11.1 was downgraded to iOS11.0.3 tutorials. If you think it doesn't work after upgrading to iOS 11.1, or if the old model doesn't feel smooth enough, Apple hasn't turned off the verification of the old system yet. You can still downgrade back to iOS 11.0.3, but then Apple will close this method, and then you can't downgrade again, so if you want to downgrade, you should downgrade as soon as possible.

The downgraded reset requires verifying the Apple ID and remembering the password.

1. Backing up data on iPhone5S

The native backup of iTunes on iOS 11.1 cannot be restored to iPhone5S on iOS 11.0.3, so here, you can only back up part of the data through iCloud cloud service, or directly connect to the computer to transfer photos, etc. But you can't seamlessly restore everything on the original iPhone5S.

two。 Download iOS 11.0.3 firmware (click on me at the download address)

3.iPhone5S enters DFU mode

Connect the iPhone5S to the computer, turn off iPhone5S, and press and hold the power key Home to turn on the computer. The Apple logo will appear on the screen. After the Apple flag disappears, press for another two seconds or so, then release the power button, but continue to press only the Home key (or the volume key). After that, iTunes will show that iPhone5S is in recovery mode and iPhone5S is still in a black screen.

In DFU mode, the iPhone5S is connected to the computer and the iTunes will display like this.

Note that if a flash cord and iTunes icon interface appears on the iPhone5S at this time, this is only the normal recovery mode, not the DFU mode. Please eject the iPhone5S or hold down the power key Home for a long time and it will restart to enter the system. Follow the steps above to try again.

4. Restore the firmware.

In iTunes, press the Shift key on the keyboard, click restore iPhone5S, and select the downloaded firmware to restore.

After recovery, I will go back to iOS 11.0.3.

5. Reset and restore personal data.

At the end of this article, I hope it will be helpful to you.
