Trying to connect via bluetooth with web Upload make display tag Effirox useless

[xjols]

Hello

I tryed to change the firmware of 2 Effirox DL213BT. I used assuming the risk that this update can cause the items useless. and that is the case. I don't know if this tags that have the TLSR Microcontroller ( I not opened yet) But connecting via bluethoot to the tag via ATC_BLE_OEPL Uploader cause the displays useless and now not appears in the list of bluethoot devices availables.

Is there any way to restore and try to install the custom firmware? Best regards. Thank you
