Connect your device to your computer, and then launch iTunes of 3uTools to see what mode your device is in.

If it is in DFU mode or recovery mode, just easy flash your device to enter Normal mode.

I've never seen a case of this before.

The way iDevices work is that it first downloads the software, disconnects from the Internet, then applies the update.

I would first download the iPhone firmware on a computer with iTunes from

remember where you downloaded it

Then plug your phone into the computer and put your phone into DFU mode.

There will be a message if done properly that you need to restore your iphone.

On a Mac hold Option on the keyboard, and click Restore. Then choose the firmware you downloaded.

On a PC, hold the SHIFT on the keyboard, and click Restore. Then choose the firmware you downloaded.

If this does not fix your issue, you do have a non related hardware problem. This will require different troubleshooting methods.

Download the latest one (I think its 10.3.2).


Okay thanks :)


Is their any possibility that the board is broken due to the failed updating of the phone ?


Not from a software update.

You could try entering DFU mode if none of the solutions above work.
