I have an old A7 kicking around that I'm trying to turn into a simple game and movie device for my daughter. I'm super new to rooting devices and I found a step-be-step guide on XDA for the "Evilocity" mod, which appears to be specifically designed for my device (link below).
I've followed the instructions step by step and after the entire process was complete, my device just white-screened and is now useless. I can't access any menus or even load the recovery menu in the boot cycle to try and "undo" this update.
Does anyone know of a way to wipe the device clean? Or get the root package to take? I'm not totally bummed out as this was an old device that nobody was using, but I'd prefer not to just chuck the thing in the garbage if I can salvage it.
