Radio issue

I drained my battery the other night sitting in the car with the radio going so I jump started it with a jump pack... stupid me put the (-) clamp on the engine support bar and not the ground post thinking that would work. Nope.... charged it alittle but not enough to turn over the engine. YouTubed the right way and voila it worked. Now, my radio does not work and every time I start my car the screen says "Loading..." (see photo)

Did I fry the fuse or what? And if I did, I assume it's the fuse panel in the rear of the car that it's located to change?

Try this, disconnect both battery cables. Now touch both disconnected battery cables together for 30 seconds. This is a hard reboot of all modules. Now the important part, the battery must be fully charged, if good, or replaced if bad. With a fully charged battery, turn the key on, without starting, and turn the radio on.
I know my ideas sounded wacky. I should have explained it better. In the early days of personal computers, when we had a problem, we would shut it down, disconnect the power cord and then press the power button for 10 seconds. During this 10 seconds, the cooling fans turned on and the hard drive light would flash. This 10 second hard reboot drained the all the power out of the many capacitors. If you ever called a tech help desk, this was their standard answer. Besides reloading Windows.

Kinda the same thing for a vehicle. I'ts possible during the jump-starting, the radio was on and the low voltage, plug the spikes while cranking, caused a logic lock.

The battery is the most important electrical item. Bad batteries kill computer, modules and alternators.

Alternators were not to recharge a dead battery. Too much of a load for them to handle. Too much load, equals too much heat.
