OnePlus6TSingle issue?

[TotalRando]

For all us OnePlus 6T aficionados, many are familiar with the fact that different versions of the 6T have different SIM slots. My question is: will the installer still work if I just choose OnePlus6T manually in the installer, or is this warning a real thing?

@totalrando Have you tried?

[TotalRando]

@thousandtopics Um, no, I guess I should do that

It's a locked bootloader. Today is going to be interesting.

@totalrando at least now you know where to start

@totalrando Bootloader can be unlocked using MSMDownloadTool at XDA-Developers. You appear to have a T-mobile model. It has two functioning sim slots, just buy a dual sim tray. Don't know why T-mobile used a single sim tray.

The OP6T image works for all OP6T models
