Foolishly tried to update iPad Pro to 11.4 from 11.2.3 (I think). Took almost a full day. Finally got a message "The iPad "iPad" (not the name I had) cannot be updated. The device cannot be found." Device screen now frozen on what I've heard referred to as the "Connect to iTunes" screen or the "restore" screen. I go through all of the rigamarole alternately asking it to update or restore only to hear the Windows "remove device" sound 10 to 15 minutes into the process and the little iPad silhouette disappears from my iTunes window. After about 5 hours, I get the "The iPad "iPad" (not the name I had) cannot be updated. The device cannot be found." message again.
I am LIVID that their update has bricked my device and that I'm more than likely going to be on the hook for repairs if I want to continue to benefit from my $1000 investment in their product. I need this product for my job and it looks like I won't be able to make use of it for at least a week.
By the way, I mentioned that I "foolishly" tried to update as I had a similar issue in my last update and after a day or two of similar heartache, finally managed to get the ****** thing to work. Won't make that mistake again.
