iPhone 6 Bricked during ios 11.3 update - error 56

Did you change your iPhone screen with an copy version? (So not in an Apple authorized Service)?

Error 56 means that an iPhone with some hardware glitch (like screen change, even if Touch Id was previously ok) is being updated. The update "senses" the hardware glitch (even if before was ok) and interupts/bricks the phone. If you have the old screen you can try putting it back and update, otherwise you need Apple Service witch means paying for a replacement phone.

The (potentially) good news is that it is not completely useless. If you replace the screen/touch id with an original part the error 56 will go away. This error practically bricks the device by not allowing it to move further because of an unrecognized/glitchy hardware part. For example if you had a broken screen, if you replace the current (non original one) with the broken one, update the phone and than replace it again, you will have a very high probability of working again. The bad news is that on the next iOS update you will encounter the same error. Better just replace the faulty part with an original one and be safe in the future.

While I empathize with your situation... to suggest any smartphone manufacturer did this on purpose is absurd.

The error code you reference is commonly associated with 3rd party screen replacements. This repair, if not done correctly can render the touch ID sensor liable to this exact behaviour.

You haven't been asked, but did you replace the screen?

the touch id sensor worked - I used it to unlock the iphone to get to the settings screen and start the update.

It works until it doesn't.

Very commonly triggered by an update which is more intrusive on an iOS device than simply starting it up each day.

You don't receive the Error 56 because you got a new screen, but because you have a faulty hardware that is affecting your device. I would recomend never to service your phone with counterfeit parts, but in your case go back to the service and ask them to replace (free of charge) the faulty part (I can guarantee 100% that they already know about this issue and most probably have functional replacement screens/tpuch id parts). In the future use Apple Service as in the long run is less expensive and 100% secure.

There isn't a way to revert back to iOS 10 as that SHSH is not signed anymore by Apple. Only 11.3 is signed and can be installed.

If the screen was not replaced by Apple and was not replaced competently your phone is useless.

Get help with iOS update and restore errors - Apple Support

We don't know for sure what changed from iOS 10 to 11 that triggered this, but the hardware glitch was present before even if you didn't see it in the form of a iOS error.

It is the same as buying anew car, but not using the recommended oil/parts and when the car breaks down you say it was a faulty car. If you use the car/phone as recommended by the manufacturer that you have a smaller probability of fault.

And by the way: I don't agree with the way Apple prices their replacement parts! I think they are over priced, but you assume a big risk when using counterfeit parts.

Same problem..... i think that Apple was purposely added to 11.3 to obsolete old devices, yessssss

Now i cant more use my Iphone!!!!

let me know if u found solution!!!

Same thing happened to me this morning. Worked great until I tried to update and now I get an error code 56 when trying to restore or update. It's bull

I recently replaced the screen. So because I got a new screen my phone is useless? Is there anyway to revert to the previous ios?

Who replaced the screen?

No. It's like something broke.
