Help - upload iBSS problem

Hey guys, I can’t get the IBSS to upload to the apple tv 2 on new IOS, successfully boot tethered twice on my windows laptop,
changed my laptop and now it gets stuck uploading the IBSS which is starting to annoy me!

I’m presuming it’s something to do with versions of windows etc ? Seas0npass for mac doesn’t work for some reason?
That doesn’t even start to do anything even when it’s found in DFU? Just says restoring but doesn’t do anything, left it for 45mins at 1 point!

Any help is appreciated

Cheers
