AngryCreation (1) as much as i know you can’t update any rooted phone with OTA update…it requires digital signature of your phone to get and update with latest update…
(2)If you can bypass the digital signature thingie… and start OTA update manually…it will fail… you can find OTA update files easily on GitHub but rooting is the issue here…
(3) You can’t use any banking apps on rooted devices …
You can easily unroot your phone with official stock firmware files…
(Rooting a phone is very risky and can brick your phone if you don’t know how to do it…so please read all instructions and then proceed)
