Apple logo reboot, unable to flash firmware


Got a iPhone SE here and the customer said that after they took it to have a screen replacement it would only show the apple logo and go into a reboot loop.

I have plugged it into 3uTools and iTunes after putting the phone into dfu mode. iTunes failed to restore. 3uTools gets to 20% and fails on 'Unable to restore iDevice(-1) the screen also flickers

I have tried multiple times.
