For starters, I have a Motorola Droid MAXX running Android 4.4.4. Today I was in the process of downgrading my firmware from SU6-7.3 to SU6-7 in an effort to eventually root my phone. Everything was going well for most of the process until my phone screen suddenly went black. I am no longer able to turn it on or enter recovery mode. The strange thing is that when I plug my phone into my computer I still hear the tone which indicates it is connected. So the computer still recognizes the phone. I'm not sure what to do here. From what I've read, when a phone is hard bricked it will be unrecognizable by the computer so I am hoping that I can still fix it. The phone is still under warranty so in the worst case scenario could I possibly just take it to the store and play dumb to get a new one? I'm really running out of options here so any help would be greatly appreciated!
