The back story. On attending the flying field found my X9D would not connect with the installed X8R Rx. This combination had operated flawlessly the week prior. Inspection showed the Rx showing solid red. Tried to rebind without success. Decided to update/reload the Tx firmware but without success. All attempts were with fresh downloaded updates from FrSky, via the installed SD card. On viewing the card content on my computer only the usual folders could be seen. However, when viewing in the Tx each file was duplicated some with ._. prefix. On trying to delete the extra files the drop down only allowed to rename on some others were able to be deleted. One of the “Firmware” folders had the newly downloaded upgrades duplicated one with the above prefix the other normal. Both seemed to execute - that with the prefix proceeded to about 30% the other to about 10% then both generated “update failed.” Looking at the Tx the bind indicated D8/D16/LR9 (I hadn’t looked at this prior to attempting update), no mention of XJT as is usual with my Horus X12S and 9XE. It appears that the Tx has maintained and reverted to a earlier protocol, despite being recently updated to 2.1.0 (all receivers have also been updated). The immediate thought was that the SD card was corrupted so that was replaced but to no avail. Have also removed and replaced internal 122 coin battery, thinking this may have cleared the cache, again without success.
My question to the wider X9 community is - How do I clear the cache of the residual D8/16/LR9 protocol?
Looking forward to your suggestions.
