Why would I want to hack the bootloader for a wall charger? Asking for a friend

You can bypass vehicle restrictions. You could potentially then use it for J1772-compatible EVs (like a Chevy Bolt or Nissan Leaf)

Or just for the spirit of actually owning the shit you pay for.

I hate the gen 3 wall connector.

It creates a wifi access point in your garage that you cannot turn off:

  TeslaWallConnector_
some people were able to downgrade their firmware to a version that didn't do that, but i guess this article shows telsa got rid of that ability.

I would love to be able to hack any firmware to disable that.

I also read that a connected tesla car can force an over-the-air firmware update maybe through the charging cable or wifi, but I haven't verified that.

I don't think there are any restrictions. I think j1772 might just work with an adapter (adapt from the nacs plug to the j1772 plug)

I thought tesla even made a j1772 native wall connector.

Can confirm. I've used an adapter to charge 2 different non-Tesla cars off my wall connector.
