Restore to stock firmware

[andy0172]

Hi, I have been using the custom firmware for a while, but want to try now the new stock firmware. I don't get it back to stock firmware no matter what I'm trying. Any hint here?

These are my device specs currently:

Hi,
I'm also using the custom firmware to try to understand how Carplay works
If you want to revert to the latest stock firmware, you can do so via an http upgrade.
Just connect via the browser to the device address

Personally I have a U2W version.
