What I was wanting to try is get Fulmics installed, then somehow 'lock it down' so security software for work wouldn't get angry
I understand that Magisk could probably circumvent that the root side of things, but i prefer to not have anything that might cause problems.
So, I installed Fulmics, then tried to fastboot oem lock and on reboot, it was not happy, got a red color message that said it wanted to power my phone down and did not want to boot.
Thankfully, Uppercut was able to push the latest 20m KDZ back on to my phone...so I'm back to stock.
