So, I'm by no means any techie who dares to compare myself to any of the geniuses in here.
But I can help you out a little bit..!
Rooting is nothing more than giving yourself full control over your tablet. When you're NOT rootet, certain aspects of controlling the tab is "locked", so to speak. And that goes for the apps, you install to. Certain files can not be changed, over-written, deleted or even just "watched", if you're not rooted. It's kinda like giving admin-rights on a PC..
Honeycomb is nothing more than the name of the Android-version for tablets, and Touchwiz is the interface and framework Samsung uses for all its Android-product - a way to differ from the other android-products. This tab was first sold without Touchwiz in some parts of the world (running barebone Honeycomb) and then got a touchwiz-update later on. Many of Samsungs own apps will not work on even Samsung-devices, if they do not have TW installed, as they're based on TW-framework.
Pushing something to a given directory basically means copying/moving it to that directory. However, as these directories are mostly "locked" folders, you will need to be have rooted your tab to do this. The "pushing"-term comes from using ADB, where you use a command that says to push the given file to the given directory. Most times off, though, you can do this with a simple file manager (with root-rights
) on your tab.
The only way I know to get new icons is to either
a) Use another Launcher or
b) flash a custom rom with other icons.
However, I'm sure there are other way to do this, that I'm not aware of myself
Hope this helps a bit. Tried not to make it too long and confusing, but I'm not so sure that went too well
