Just to know

Hi.

I've installed a custom treble gsi ROM last month but he's a little bit unstable and pre-rooted.
So, i've found Descendant ROM and i install it recently. I've installed that ROM with fastboot, with "fastboot flash system system.img" after factory reset on TWRP.
so, custom rom works perfectly but root is always on my phone. It's normal? Or i need to do another something for that?

Thanks for read me and sorry for my bad English, i'm french.

Have a nice day.

Cyril
