Unhappy [Q] My Rooted Htc One m8 keeps constantly rebooting after trying to modify a file

I unlock bootloader and root my One m8 but was trying to modify a file in system/customize/acc default.xml and it's now on a constant reboot and very hot. Is there a way to fix this or my device is screwed up. Please I love this phone and it was working well up until this. Hope you guys can help me.
