How Can I Root OOS 10?

thanks in advance! I tried multiple times and i keep getting stuck in a boot loop and it keeps going to the bootloader. Couldn't even boot back into my phone OS. I couldn't get out of it so i used the MSM tool and i am officially back to 9.5.3. Can somebody please let me know if i can update from this and stay rooted, or can i update to OOS 10 first and then root from scratch. I appreciate all help! I'm sorta a noob to this, so i apologize in advance if its a noob question.

How to revert safely back to stable Oxygen OS from a custom ROM

Hey guys,
So I had flashed custom ROM on my OP7 couple of times, and on both the occasions, when I tried to revert back to stable Oxygen OS, I ended up in Qualcomm crashdump mode.
Now it might seem like a noob request, but can anyone give me a detailed guide on how to revert back without actually bricking my phone.
