Same issue on another (1) iPhone 8 , (2) iPhone 8 Plus, & (3) iPhone 7
The process has been tested on 3 different machines (2 laptops & 1 desktop) running Windows 10 x64; and using the latest version of UnlockTool, Ramdisk files & Apple drivers.
Any idea ?

Iphone auto reboot normal or you can check comport auto disconnect, Windows need already enable Test Mode

 

[azchamoun]

No, devices not auto-rebooting.
Device Driver Signing is disabled & Test Signing Mode is enabled in one of the machines.
But I just noticed that after sending "ibss.img4", Apple Drivers are missing from the device Manager on all machines.
