Phone stuck and won't boot, stuck at the recharge thing when the phone is off

My S6 won't boot after installing the COJ5 firmware and then installing the Superstock 2.6, I have Upintheair's kernel. If you turn your S6 off and look at the recharge thing, it is stuck on that and it won't turn off, and I can't turn the phone on at all. I followed all installation instructions correctly.
