Power-Up 4.2.1.2 - Addresses modem issue

Jim657 · Mar 23, 2023

Just receive my Power-Up 4.2.1.2 today which specifically addresses the modem so hopefully that’s the problem solved. I am in Canada and just received it on the 23rd. However, mine has not disconnected since the previous update.

I got this as well, only a week or two after getting 4.2.1

Under which operational process?
Manual on/off
Remote Start (are your remote start preferences changed)
Departure time (are your preferences changed?)

This morning departure time did not start and toggling on and off did not work. Also my Ford pass app has a new logo so it updated last night.

Does anyone have the 4.2.1.2 release notes?

This is all that the app says:

So this is a '23 MY-only update?

This is another update, in conjunction with the most recent 4.2.1, (not the one that came up before March) to assist with Modem connectivity issues. Nothing else was added AFAIK.

Got 4.2.1 couple days ago. But no YouTube. Thought it was supposed to be on 4.1.3.

After waiting over a week for 4.2.1, tried fuse pull, BMS reset. App said updated but truck showed Ready for Download. I put the truck on a trickle charger this morning. Updated to this release! Maybe a coincidence.
Swear it showed Update Completed. Went and checked again. Back to download.

I received my Power-Up 4.2.1.2 today too.

So that I’m not crazy (up for debate). What does the screen show if you into Software Updates menu in the truck? App says updated, truck showed Updated, now shows waiting Download, as seen above. BTW, still on revision 640 so nothing has updated per Sync.

The screen you saw in your truck after 4.2.1 successfully updated was an error by Ford (confirmed). The update did install correctly, just left that phantom screen up.
