Please forgive my newness, but I’ve searched around and can’t seem to find an answer to a scenario I’ve gotten myself into.
I recently set up a Pi Zero W with NOOBS and set it up to dual boot into Raspbian/OSMC and included a 500MB shared data partition (which I understand should be accessible from either OS).
After doing some initial configuring of Raspbian and getting it set up the way I want (at least for today 
) I booted into OSMC only to find out that NOOBS installed the February release which doesn’t support the Pi Zero W’s wireless chip. Everything else in OSMC seems to work fine, I just have no network.
Is there any way I can upgrade OSMC without a network connection by adding/accessing/installing files from my shared data partition? Raspbian is fully accessible over the network.
Thanks for any nudges in the right direction
