Hello everyone, this is my first time using the forum. Sorry for any mistake committed by my part here.
I'm having a serious problem with my Arduino Nano recently. I already followed all troubleshooting steps and none of them worked. I will put some extra facts that maybe would help you guys figured out what's happening:
1- The loopback test didn't work. Basically, when a value is sent via serial monitor, there's no echo, just a blank field.
2- When the Nano is powered up, the "L" led always blink 8 times.
3- When the sketch is uploading, the RX and TX flash a few times with a very low LED intensity.
4- I tried to burn the bootloader with my Arduino Mega but it didn't work, and yes, I did everything right.
There are two things that could have done this with the Arduino:
1 - I broke the USB capacitor and I didn't replace it yet but this occurred a time ago when the Arduino was still working perfectly.
2- The day that the Arduino stopped working was when I decided to plug a 9V battery to power both HC-05 and MPU-6050 modules, and I swear, I didn't invert the terminals of the pins. Besides that, the Arduino was already plugged into the USB.
This is the message I get when the Blink sketch is uploaded.

Could someone try to hypothesize what is happening and what could be made to solve the problem? The Nano is like a zombie, I don't know if it's dead or alive.
