Hi everyone, I try to revert back to BLE from Version 3001-1100. OTA update always say: "**not a valid OTA file**". I tried it with three different firmware files: 1141-0203-99993001-ATC_v46.zigbee...

Zigbee2mqtt shows Custom devices (DiY) - LYWSD03MMC with Firmware-Version 3001-1100 Zigbee log: installed_version":285224961,"latest_version":285224961 whitch firmware file is to use to get device updated to LYWSD03MMC**-z** with Firmware 3001-0123 ?

@arnizzz whitch one did you use? can you post link and filename? would be helpful. - Thanks

still doesn't get OTA to run. Error is "z2m: Failed to check if update available for 'Xiaomi' (Not a valid OTA file)"
