Tesla Wall Connector bootloader bypasses the firmware downgrade ratchet

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

I hate the gen 3 wall connector. It creates a wifi access point in your garage that you cannot turn off: TeslaWallConnector_<unique-id> 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.

Repeat after me: An owner voluntarily downgrading firmware to gain control of your hardware IS NOT A HACK. And if an adversary is doing this, then they have already breached yoir physical security.

PSA: If your wall connector loses wifi, it'll just throw your charging schedules out the window and turn on/off sporadically. This is especially noteworthy if you have Time of Use billing :| SET THE TIMER ON THE CAR DIRECTLY!
