Hi guys i bought a iphone xs online with a shattered

screen, i couldnt see wether the phone turns on or not

since the screen was heavily damaged, i replaced the

screen with a screen from aliexpress, i fitted it in and

tried turning it on, it just keeps bootlooping, the apple

logo shows for 3 seconds, then it goes blank for a bit

and then the apple logo shows again for 3 seconds

would i need a new battery? if not does anyone know

what could be the problem?
