T-Mobile OnePlus 8T + 5G I have since activated it on my Metro-by-TMobile SIM and it's working perfectly.
How would I go about getting my bootloader unlocked ?
Thanks my friend.If you dial '611' & tell them that your a developer & that you need the bootloader unlocked they should be able to help you. Good luck and let us know how it goes.
If anyone needs to SIM UNLOCK & OEM UNLOCK the bootoader: goto Settings> WiFi&Network> SIM&Network> Network Unlock. If anyone can help on how to get the token unlock code, it would help some. For PUK and other unlocks https://www.t-mobile.com/support/devices/android/oneplus-8 and then scroll down to Security. There you have option to unlock several things.
