Yeah, unfortunately the display/esp32 can now only be purchased pre-flashed from specific retailers (for a significant markup) and the firmware is no longer published anywhere. The only way to update is OTA.
It’s all really shitty. Though, I’ll admit, I really didn’t have high hopes when I found out that they use discord for everything from troubleshooting to documentation to group buys.
I bought the parts to build mine a year ago and never got around to it. I’ll still build it, but it’s sad they are either ripping away all potential future support, are fracturing the community, or both
