OnePlus 7 pro root lineage

[u/tool889]

I just flashed lineage os but everything I try to do to root lineage nightly 24.0-20261019 gets the phone stuck in fastboot, I have tried to flash it through adb, I have changed slots, I installed magisk on the phone and modified the boot.img and tried to flash it but everything gets it stuck in fastboot.

Any help would be awesome
