iPhone 7 Plus stuck on black screen.

[Curtis-E-Bear]

Not sure if I’m posing in the right place, but I have an iPhone 7 Plus that crashed during an update to the latest 14.3 firmware.

The screen remains off until plugged into the mains, then the apple logo appears, then disappears intermittently.

I put the device into DFU mode, at which point it is detected by iTunes and prompts me to restore/recover. iTunes goes through the usual download and update process then the screen briefly shows the apple logo with the spinning/loading wheel below before disappearing. The screen then remains black and iTunes show ‘waiting for iPhone’ for a long time before displaying error message 4005.

I’ve tried different cables in different USB ports but nothing works.

Any help is greatly appreciated!!

Thanks I’m advance.

Can you download the ipsw file and then install it instead of having iTunes download and install it?
