No problem, I admire your patience.... but something is badly screwed!!! Just don‘t know what ... yet
Hopefully the additional debug will hopefully tell me what..... compared to ImageManager this code is really simple, so its like it doesn‘t realise its a HD51 receiver........
if it doesn‘t work will have add more debug.
What we can also try is copying STARTUP_2 to STARTUP (overwrite) but lets try the 1st step and then see..
