Some rooting/custom ROM questions

[danduson]

Hey, I hope this is the right place to ask this, as this is a general rooting question that is not relevant for the device
Anyway, I have a few questions I hope you guys could answer me
1. From what I've understood, when I want create my own ROM, downloading the source also includes the actual OS right?
2. Assuming I'm creating a costume ROM, will I be able to:
a. Have a complete control over connections? As in, create an app that will be able to (with out notifying the user) turn off/on any connection? (BT / wifi / GPS / NFC or anything else)?
b. Make an app that will have access to the OS's file system?
c. Make an app that will be able to control the content of the device, as in, add or remove any given app?
d. Will I have access to the OS drivers? As in, will I be able to remove drivers or add costume drivers?

1. Yes, you will download the source to build the OS, as well as the Device Tree, Kernel, and Vendor Files.
2.
a. Yes, that is possible, if you know how to make an app.
b. Yes, that is possible, if you know how to make an app.
c. Yes, that is possible, if you know how to make an app.
d. I'm not sure that I understand the question, but yes, you will have access to the BLOBS (Binary Large OBjectS) that are the drivers for your device. You can substitute them or build other ones, depending on your phone or platform.

I recommend that you watch through my video tutorial on how to build Android, and how to make device trees from scratch, as well as other videos about upgrading and making changes to apps that are in your custom rom.
