Woke up to "bricked" iPhone 7 Plus, Genius said Facebook app caused issue?

I am having a similar issue and I am at my wits end on this one. My iPhone 7 Plus got bricked and I don't even know why. I have attempted numerous times to restore from iTunes and it will just keep going back to DFU/Recovery mode. What to do from here? I was told by an Apple tech at a local store that it's a hardware issue and to ship to Apple for a replacement. I have never had issues with the iPhone before until now.

For what it's worth, this version of the app appears to have its share of less than stellar reviews in the (U.S.) App Store.

I Know I'm kinda late here, but I had the same problem 10 days ago on my iPad Air 2.

My iPad suddenly rebooted and got stuck at the apple logo, i had to restore it (thank God I had everything backed up), and when it finished I noticed all apps are there except for facebook. So I reinstalled it manually and my iPad immediately crashed and had to restore it again.

i Haven't seen many similar cases around, which is kinda weird. Now I'm forced to browse facebook through safari. 😠

I know of 3 people with iPhones 7 which were working fine when the user went to bed, only to have a bricked iPhone when they woke. However, I have seen iPhones 7 brick before my very eyes when installing software. I'm also a 7 year iPhone developer and have an app in the store which a user reported "bricked his phone" when installing the app. Our app does contain software from Facebook, but ANY app bricking a phone during installation simply should not be possible.

I can't help but assume the iPhone 7 has a hardware/driver flaw. Has anyone else experienced something similar? OP, have you seen any issues since your iPhone 7 was restored?
