Yes, miniloader will update the BCT with the new value if you send
this command after downloading a BCT.  Really the only thing I'm using
this for is the side effect inside miniloader that causes it to
reinitialize the UART with the new odmdata value.  For some reason
when you donwload the BCT, miniloader does not do that, and when you
boot in recovery mode there's no initial BCT so UART never gets
initialized in miniloader and you get no debug prints.

Will do.
