Hi all

I have a valid Dev account and am trying to install the Beta5 on my iphone 5.

Im sure i have the right version but each time i try i get "An unknown error occurred (4027)"

I've tried DFU mode / different machines and restoring to a fresh 6.1.4, any one else any ideas?

Thanks

Marc
 
Using 11.0.4.

I just realised my iPhone had been replaced since i last installed iOS7 so my new UDID wasnt on my list but ive added it and still have the same issue :(

----------

Am now getting an error saying "This device is not eligible for the requested build."

Im 100% sure i have the right one (Iphone 5 Model A1429) as far as i can tell from the back.

Is there a way to check the model in settings just to be sure?

Thanks
Marc

Its currently running iOS 6.1.4 (restored to this to take back to apple for a different issue)

My phone was replaced and now i dont seem to be able to get any of the beta's on here, very odd :\

Have you tried a different computer?
 
Just did a google and deleting some hosts entries seemed to fix it.

Ive no idea why they were there it mentions when jailbreaking but ive never jailbroken my phone since ive had this Mac..

No idea but it seems to be working now, thanks for the suggestions :D
