Error 6 iOS11 Downgrade

Postby liljak » 18 Jul 2017 20:32

Hi all,
This morning I attempted to downgrade my iPad Air 2 from iOS 11 Pb1 > to > iOS 10.3.2
I tried this via iTunes with FindMyiPhone disabled but the update failed, this left the device in a recovery state.
When forcing the device into DFU and restoring to 10.3.2 an error is returned (error 6), the same happens when restore is started in recovery.

When attempt to flash via 3U it errors with (error -6)
I've attached the log of 3U.
Your help is appreciated

What do you mean by changed network? I have the same issue. My iphone 6 gets stuck at "Sending FDRTrustData" and then it fails.

Cn you kindly tell me what different steps did u take?

He said he was change another internet to connect, meantime you can try to change another computer, another USB cable to flash again. Hope it works.

What if you don't have another computer?
