[Moto G6 Questions & Answers] Moondroid:
I see what you mean. I reflashed last night but didn't think to run getvar and compare. I just did that, again after reflashing FW downloaded through Lenovo Rescue and Smart Assistant, and those slots still show invalid . . .

Another thing: On this phone OEM Unlocking shows completely grayed out. But on another G6 (XT1925-6) that I picked up cheap in an eBay auction, the OEM Unlocking verbage is not grayed out. Just the button.

Edit/Add: Identical phones, exact same firmware. The second phone also shows those slots as Invalid.
