Help needed with Samsung S7

[d7e7r7]

I tried to root my phone (Samsung S7) earlier but now it seems it's stuck in a boot loop. Just keeps showing the pulsating Samsung logo. Can't put it off/on. Is anyone able to help me this evening in Cape Town? I can come round to you if need be...

I really hope I haven't lost everything
