Managed To Brick iPhone

If your iPad/iPhone will boot, but not unlock (like mine), I found the only way to get it back was to use "Find iPhone" on another device, and remote wipe. I know have my iPad back working with iOS 11. Hope that helps!!!!

I'm having the same issue. iOS 11 has installed okay on my iPad - but on my iPhone it goes into a loop on the Apple Logo screen. Occasionally it will display the passcode screen but I can't type anything. I've now had to restore this phone 3 times... I just can't get iOS 11 to install !

Something is seriously wrong..

My iPhone is an iPhone 6s Plus

I have tried a few times to get to IOS 11 on my 7+ without success. Tried OTA, updating and restoring via iTune. So have restored back to 10.3

I'm getting the same error.

I did see on Twitter that it could be caused by the carrier, and when mine worked (momentarily) earlier, that was when I was on the tube with no signal!

Apparently removing the sim card fixes this, but if you still need cellular data, returning to iOS 10.3 is probably the best answer for now.

No sim inserted on IPhone 6S does not loop insert Vodafone sim and goes to black screen with dial.

Hw do I do a factory reset back to IOS 10.3?

Connect to iTunes, put your phone into recovery mode and select 'restore'

My 6s is my test phone. Got it to install, but keeps locking up. No way I'm putting this on my 7plus. No issues on my ipad air 2 though.

same for me on my iphone 6s plus (UK model A1687)

boot loops no matter how I install ios 11 beta 1 (OTA, update through itunes, DFU)

totally unusable, spent hours only to have to revert back to 10.3.2 which works perfectly

out of interest are you on vodafone UK? as I'm hearing that the carrier may be the issue....

i am on vodafone and have this issue.

Funny enough I am on UK Vodafone on my iPhone (which doesn't work).. However, my iPad (also on UK Vodafone) didn't have an issue with the upgrade.

I am on Vodafone in the UK as well and had this issue with 2 x iPhone 7 Plus

Has anyone tried doing the IOS 11 upgrade without a SIM Card installed ? Or does it also fail ?

Same here. Vodafone UK - iPhone 7 plus.. completely unusable when mobile data is on.

ill wait until public beta to be released and use it on Iphone SE

So - I've taken my Vodafone sim out of my iPhone and have put an EE Sim instead. Now doing the iOS 11 upgrade - wish me luck..

If this works them it must be something to do with the Vodafone. What will be interesting if the Upgrade works is what will happen if I put the Vodafone sim back in..
