    You might need to use the unbrick tool then to get completely back to stock.

    Boot back into android and make sure OEM Unlock is turned on. Having that off can do this.

    Hmm, don't know. Reflash your rom, something wrong.

    If you have the 3 (not sure where the 3T one is) use the unbricking tool (there's a forum post stickied). Get your phone back to absolute bone stock that way. Make sure you follow the instructions to a T.

    Sorry I didn't get back to you right away. My wife and I just had a new baby over the weekend so things have been a bit haphazard. I'm glad you figured something out!

    I had the SuperSU installed on my oneplus3t once i unsintalled it and that unrooted my phone how do I lock the bootloader and OEM lock again ? I did follow your post also but failed when I got to the part where it was telling me to install from adb had about 42% transfered. Knowing me it's probably because I already unrooted via SuperSU and was already on the latest update and also I'm knew to the oneplus3t

    From what I'm reading you didn't follow any of my steps at all or didn't read carefully. Try again.
