I tried to update my iPhone 8 plus to the public beta of iOS 13, but my phone died at the end of the update. Is there any way to get it out of bootloop? P.s, my lock button is broken. The phone is in overall bad shape, but I just wanted to get it to turn back on. Thanks.

If you have a copy of your data, you could do a DFU Restore of iOS.
