I couldn’t unlock my bootloader on my oneplus 9 pro. I also tend to need DETAILED instructions for things, so there is a chance I missed a step and didn’t realize it. I also didn’t know that there’s a difference between rooting and running a different OS…I thought they were the same thing.
I was trying to degoogle and permanently remove the google shit, and at the time this model had just come out and there wasn’t much about it. I may try again on this phone when it starts to go.
