Can't update after root?

[zamhau]

Hey guys. I'm currently having a problem that I have researched for a long time now. I haven't been able to find an answer because most people use Samsung. I have an LG L90 D415 that I rooted. I did try to unroot and update but it didn't work and that was a long time ago so maybe I did it wrong? Anyways, any help or suggestions is appreciated.

That's pretty much expected if you root. Even if you unroot, the system has recorded that root permissions were previously active hence you can't update. You need to flash stock firmware.

Thanks for responding. But how exactly do I "flash stock firmware"?
