I bought the Display Bundle. When it arrived i plugged the shield in the Arduino and connected it to my phone charger. The screen was black but lighted (it was normal). After plugging out the shield i connected the arduino to my PC. No blinking sketch was preinstalled (no leds turned on) and there was no COM port. I got a little mad and forced the usb c cable to fit in and then heard a small "crack". Now when i plug in the cable the arduino doesn't turn on (I know because when it does is a bit noisy). But when i press over the usb c connector it turns on but no COM and no leds. I learned too late the double click reset button trick (the green led blinks but no COM). In my opinion the Arduino was already broken or I broke it when i plugged in the display shied (i heard on forums about power stuff and broken Gigas). Even if it is not constructive i want to say that Arduino should have provided a normal USB c connector (like my phone's one); i wold have gladly paid an higher price for that. My frustration apart i just want to know if there is any hope for my Arduino to come back to life.
I don't know what you think your pictures are showing.
By your own admission you broke the USB-C connector.
I got a little mad and forced the usb c cable to fit in and then heard a small "crack".
There is a way to fix it? What is broken (in detail)? I don't think the only thing broken is the USB connector, the arduino didn't work before the crack (no blink scketch pre loaded)
Yes it did.
Search for "circuit board repair" (not by you, by a professional)
Only power worked. I haven't programmed the arduino a single time (before and after the "crack") and the default arduino sketch didn't run when i turned on the board for the first time. After reparing the USB C I might try to rewrite the boot load (don't know how). I powered the arduino using external source (VIN and GND) thanks to another Arduino MKR, the default sketch didn't start.
Easy details are to completely remove what is left from the connector, including any pins/wires in or on the board that made electrical connections. Replace with a new copy of that connector.
Without knowing your skill set and the tools you have available, I suggest purchasing two more Arduinos as backups. Keep in mind that there are hundreds of different phone chargers available, and not all are compatible with the Arduino. The fact that your charger did not fit might indicate it provides the wrong voltage.
It’s true that there are many different phone chargers, and not all are compatible with the Arduino. A mismatch in voltage or connector type could be the issue.
Check this link for more details. Note that they also did not include a Lightning connector. https://www.howtogeek.com/53587/usb-explained-all-the-different-types-and-what-theyre-used-for/

It worked here.

You did this.
- It does not work here.
Problem solved. Get a new board, read the instructions. You will have a great time.
I don't find the link you are referring can you send it again, it could be useful. I believed the USB C protocol would have provided the right voltage for the Arduino (I think it's called USB C power stack) but probably it was not the case
