Stuck in Bootloop and can't access recovery mode?

I have a rooted, leaked version of GB installed and I was fooling around with some settings on jrummy's overclock app (set phone to low voltage, got rid of boot animation, lowered LCD density, lowered Dalvik heap memory, turned on the ad blocker feature, and lowered the proximity delay). These changes required a reboot so I did, and ended up with this problem?

The solution is to just sbf the phone right? But if i can't access the recovery mode (it stays stuck on the triangle with an exclamation mark inside despite me pressing the search button), how do I accomplish this?

when you get the exclamation point try hitting both volume buttons

EDIT: I used the power button to select instead of the camera button and it worked. Thanks!
