@torsten, unless Athom comes up with an easier way to do this, you need to disconnect from power, open the case, locate the serial pin holes (3.3V, TX, RX, GND), connect a serial flasher (in 3.3V mode!) and use esptool to erase the flash, then write the bootloader and the firmware.
Followup to my previous comment: I managed to recover the controller by opening it and flashing via the serial port. However, just flashing WLED_0.15.0_ESP32.bin again lead to the same dead controller. I had to
Erase the entire flash
Flash the bootloader
Flash v0.15
Reconfigure WLED from scratch (also assign GPIOs etc.)
I suspect there is something about the flash or data layout chosen by Athom that stock WLED can't deal with anymore. Maybe that's also the reason Athom hasn't released 0.15 versions of their custom firmwares yet?
The flash memory and partition layout are completely fine, it is the same as the official one, and the chip itself is even fine, because all our chips are purchased from the original manufacturer. You should check whether your firmware is correct. If there is still a problem, please contact customer service and provide your firmware so that we can troubleshoot the problem
Today, I tried exactly this via OTA, but it seems to have bricked my controller. I have used WLED_0.15.0_ESP32.bin (sha256: 9943fb09592dab19ff5e482b1a03f284927ddf64af5d74fedac9eea23de5e408).
Yes, it is possible.You have to properly set up the mic.And if you have remote, it will not function properly. If you want IR Remote function, you have top wait for custom firmware.

Another followup, I even managed to get the mic (sort of) working with vanilla WLED 0.15, by using the configuration at the very bottom of this post.
My upgrade to firmware V15.0 failed. And also a reset of the controller failed. What can I do?
