I purchased a Oneplus 6T to try out @mobian on it. However, it turns out there are some of them that are T-Mobile branded, and to unlock it for Mobian, the official procedure is to first ask T-Mobile to SIM Unlock it then ask Oneplus to unlock the bootloader.
Thankfully, someone figured out how to just reflash the entire phone so you can skip both of those steps! The process is here: https://www.xda-developers.com/t-mobile-oneplus-6t-international-without-unlocked-bootloader/
You have to run Windows bare metal for it to work (I tried a VM, it didn't work).

@kop316 @mobian cool to see the Android unlocking/custom ROM community is still alive!

@kop316 I just did this last night. Worked great. What method did you use to update the firmware though? After using MSM, the phone would be on OxygenOS 9.0.11. I think putting any Linux distro requires updating the OOS version (and firmware) to something newer. But my phone is not getting OTA updates. Is yours? Am also trying to use the Oxygen Updater app from Google Play Store, but haven't gotten that to work yet.
