After 5 years a new update for Boot9strap is available. This is what allows Boot9/Boot11 code execution on your 3DS so we are able to run unsigned code. You are able to update it with SafeB9SInstaller, with instructions below. Maybe in the eyes of Nintendo the 3DS is dead, it shows that its still alive in the homebrew community's eyes.

https://github.com/SciresM/boot9strap/releases

what got updated:-

Boot9/Boot11 code execution.

• Boots around 0.25s to 0.4s faster
• Size halved, now under 16KB
• If the ntrboot combo (X+Start+Select) is held, or if either FIRM file is corrupt, the notification LEDwill display the following:
  • SD FIRM successfully loaded: green
  • SD FIRM missing, CTRNAND FIRM successfully loaded: yellow
  • SD FIRM corrupt, CTRNAND FIRM successfully loaded: orange
  • SD FIRM missing, CTRNAND FIRM also missing: white
  • SD FIRM missing, CTRNAND FIRM corrupt: magenta
  • SD FIRM corrupt, CTRNAND FIRM also corrupt: red
  • in addition to the above, the LED will blink if it is actually a ntrboot boot
• Ability to dump boot9/boot11/otp removed (recent Luma commits auto-backup otp.bin anyway). It's also how such improvments could be made in the first place
• (∩ ͡° ͜ʖ ͡°)⊃━☆ﾟ

Use SafeB9SInstaller to update it.

https://github.com/d0k3/SafeB9SInstaller/releases

1. Download boot9strap-1.4.zip and unpack it's content into a folder called boot9strap at the root of your SD card.
2. Then, put SafeB9SInstaller for your 3DS sd card and unpack SafeB9SInstaller.firm to /luma/payloads/ on your SD card.
3. When everything's done, boot your console with start, select SafeB9SInstaller.firm and follow the instructions on screen.

probably in the source code. you'll need the home button iirc, just to get into settings.

I accidentally broke the zip connector and it won't keep the pins down on the ribbon anymore.

I think you could still use it, but it would be pointless if you couldn't get into the menu.
