Erasure fails on iPhone 7 Plus (Unable to send iBEC)

[skortela]

Hi,
I have problem with iPhone 7 Plus erasure.
It always fails on two computers, and always succeeds on with one pc.

Last lines of failed erasure:

found device with ECID 0005799e04fa8326

What might be the root cause of failures?

The root cause seems to be on libirecovery project side.

Could be related to Apple device drivers from windows update.
See libimobiledevice/libirecovery#41

I changed deviceIOControlCode from 0x220195 to 0x2201B6 and that resolves the issue.
