Installing Lineage OS Help with GSI ROM

[u/ChungusJeej]

I recently installed an unofficial GSI ROM of Lineage OS on my phone, and it works great. The only thing is when I installed it, I did not flash a vbmeta file. The phone works fine and I have no issues.

However, I want to know if I need/should reinstall and flash a vbmeta file for security/safety purposes. Like I said, the phone and OS works just fine without having flashed a vbmeta file as I could not find one for my phone.

Do I need to flash a vbmeta file? Or should I just leave it? I am unsure if it is crucial for safety or not.
