Can't downgrade M234sdwe firmware

[NEvaldas]

Via help of forced auto-updates my printer received update 20250209 which bricked lots of M232-M237 printers, including mine. As of March 10th they removed that firmware and there's 20240813 as latest firmware. However, I can't downgrade it. Via web page admin it says that it's up to date and manually trying to install 20240813 simply does nothing. It seems to me that it send this update to printer queue, but printer is not picking it up because it's in error state. Kinda feels fully bricked (unless in near future they will release a newer update instead of older). Not sure, but are there any other options to try? There's no USB port in this printer, there's no ability to manually provide update file through web interface.
