When I firstly opened the ExpressLRS Settings on my Radiomaster Boxer (ELRS!), a loadingscreen appeared and it won't show me the settings. I've tried everything I could, I set the Hardware and Modules to CRSF, I updated EdgeTX firmware to the latest version, I've tried flashing ELRS multiple times without succes as i get errors all the time, i replaced the Lua Script with the latest one from ELRS. Since then, instead of the "Loading..." on the ELRS Tab is "Lua r16 InternalTX...". I've looked in the back, and it seems like the internal ELRS module is working without problem because of the flashing red LED.

Make sure the baud rate is set to at least 921k and retry

Did it work before? Can you show a photo of the back with the module and battery covers removed?

The yellow sticker tells me it's not the ELRS version of the boxer.

But how ist then the elrs.lua script preinstalled?

#

The yellow sticker means that the boxer is LBT conform, so its a legal measure

It can be used for an external ELRS module too.

#

The yellow sticker means it's a CC2500 radio, not a radio with internal ELRS module.
