Last OTA was Feb, The BCM. Nothing has attempted after. You have 2 updates. CMR and Gateway.1FTFW1E83MFD03497, please.
The gateway would lead to an APIM and then another Gateway then finally a TCU
You are at the level that oTAs should be working.
I would try the submit feedback in Settings/general/
Select updates
Wireless updates not working
DO that 2 times.
Wait a couple days.
I cant say it works 100% but it seems to.
