I'm not sure exactly what I did because I had the same problem as you, but all i changed was going into "Album" from the home screen, then scrolling over to "Kosmos Toolbox", then "Background services". I have sys-clk, sys-ftpd-light, and Tesla enabled. to start I went into my house with an empty inventory and pressed Connect and then Read in NHSE. after that I was able to modify stuff and press Write, i get a prompt saying "Same" and my inventory is updated. Give it a try and if nothing else i can try to help with other stuff
