S8 PIE update rollback

[Mark D3]

MMS won't work with mobile data off now and Scheduled message disappeared! Anyone know if there's a fix in the works? Factory reset isn't an option!

MMS technology never worked without mobile data anywhere. It would be your carrier implementing WiFi texts. You'd have to take that up with them. Scheduled messages is there. Tap the + icon then the 3 dots.

As for "rolling back" an update, you can't. The update doesn't "add on" to the old version, it replaces it. You can flash Oreo, but you lose anything you've done to the phone (downloads, app installations, pictures, music, etc.), so you have to back everything up first, then restore it when you're back to Oreo. (And the phone will eventually update anyay unless you root it and freeze the update app - in which case, you won't be getting all the security patches.)
