Hello,
I have an old Turnigy 9XR radio with an old open tx version. I would upgrade it. Trying to download the last version I get the error message "Invalid board" .
After searching I got that the 2.2.1 and 2.2.2 firmwares for the AVR were deleted since created problems and the previous 2.2.0 or 2.1.9 are ok.
I can't find any way to tell to companion to download the older version. I even loaded the old 2.2.0 companion and disable the automatic upgrade but it always try to load the 2.2.1.
Can you help me
Thanks
Al

2.2.0 was not OK. As mentioned you need to use 2.1.9 using a 2.1 companion, there simply is no 2.2 for AVR radios.
