I suggest you start your own thread. This thread has a title that implies it is concerned with 996XT firmware upgrade issues. You are not interested in that kind of help.Well I am having the same issue.
I am trying to update the firmware for re-banding.
I cannot find any older firmware updates as it was suggested previous.
I have BC796D_V3_6_0. and BC-VUP_188.8.131.52
I can run ARC250 fine and read everything.
This darn thing wont upload and I have a dedicated com port !
I tried all baud rates too, I wonder if changing stop bit or parity would help ??
This is a simple task and it wont connect !!
