История для "Boot loop on att logo"

I just relaced a customers lcd screen replacement for their galaxy s8 att model. No the phone is in a boot loop, it will get to the att logo, freeze there and then restart. It will not let me into recovery mode or into safe mode. I do not know if it had this issue before because the lcd was broken, please help. Thank you!
