As far as the update goes, you don't have to update the root or the whole setup; it is already configured and set up with the latest build. There is no need or requirement to do any of those things; leave them as they are.
The phone has the original Pokémon Go app. You can use your Google Gmail ID for the Play Store and download whatever app you want from the Play Store, and if those apps get any updates in the future from their developers, you can just update them without any problems, including Pokemon Go.
If you are using PG Sharp Android and Ipogo on your iPhone, stop using them; they will get you banned. An alternative to PG Sharp is Polygon. An alternative to Ipogo on the iPhone is the Android-rooted Ipogo app. These alternative apps are safe.
All other rooted apps installed with the current setup will not get you banned; they are ban-free. This rooted phone is set up so you can play the game manually with a GPS spoofing with Polygon GPS Joystick. That's a free service for which you don't have to pay, and it takes 5 minutes to learn.
Or you
can use apps like Polygon, Pokemod, PGTools, and Rooted iPogo; these
are automatic bots for which you have to pay monthly fees to their
developers through the Discor D group.
The phone is set up both ways, depending on the user and how they want to play once they buy the item. Polygon has a lot of options and tiers to choose from. If this is the first time you are using Polygon, then get the lowest tier.
Once you get to know the features, you can go to a higher tier, but always keep this in mind whenever using an automatic bot’s app. It doesn't matter which one you use. Set up one task at a time, and don't set up so many tasks that it will put stress on your phone's battery. Keep the phone properly ventilated.
