samsung galaxy s7, stuck in a boot loop.

[AC Question]

i tried to change it from sprint to open carrier so i could use on straight talk but once i tried to reboot it, it wont load up anything but flashes the galaxy s7 logo and goes back to black. i can load android reboot options and download but it wont let me do anything from there. Help me out here?
