[Samsung Galaxy S7 Questions and Answers] brycegreen:
I have an S7 from AT&T. I'm not bricked or rooted, only debloated. Amidst all this debloating, I fear I have disabled something which recovery mode requires to work. I hold down the power button + volume down and I'm put into a loop of Samsung logos.

Does anyone know what needs to be enabled for recovery to function? Here is a list of everything I have disabled:

It is not "asurion.android.mobilerecovery.att", that is an AT&T recovery app.
