I've seen it mentioned a few times that firmware updates don't always work when booting from non-Apple storage. Well, I took a moment to check the firmware on my 'MacBook Pro (Retina, 13-inch, Early 2015)', the MacBookPro12,1 A1502 model, which had its Apple SSD die out of warranty and which now carries a Samsung 970 EVO Plus. It's been updated to Catalina for a while now and just got the 10.15.3 update from a full installer.
The boot ROM on this machine is stuck at MBP121.0176.B00, where according to @tsialex firmware updates list it should have reached 188.0.0.0.0.
So the obvious question - is there a way to get this thing to upgrade its firmware without trying to find an Apple branded SSD on eBay?
