[General Topics] Easy_as_Pi_3.14:
Backstory: I, for the longest time, had a partial driver installation that wouldn't properly install. I could get file management, but nothing else. I tried to uninstall them, but there was no apparent way to uninstall the drivers because the installation was broken and Uninstall.exe hadn't existed yet. I was suffering with an unrooted, unstable S3 for a while. Before, I was lucky to root my Skyrocket without the computer at all with Saferoot to get off of TW, but the S3 wasn't so lucky... My original post.

Here is how I fixed it without messing with RegEdit. It is a bit complicated, so bear with me. It seems to work, though.

First, open the file explorer (Pro tip: Hold the start button and press E) and in the address bar, type [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]C:\Program Files\SAMSUNG\USB Drivers[/font]. If you see [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Uninstall.exe[/font], right-click it, Run as Administrator, let it uninstall, and you can skip 7-10. Lucky. Otherwise...

Download 7-Zip and install it. I suggest 15.xx beta, the 9.xx is old.

Download the official universal USB driver from Samsung. [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Don't open it yet[/font].

Now, find the driver ZIP file. This is most likely going to be in your Downloads folder as [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]SAMSUNG_USB_Driver_for_Mobile_Phones.zip[/font]

Right-click on it and find [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]7-Zip > Open archive...[/font]

Drag the file in the window to your Downloads folder, and close 7-Zip.

Right-click on [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]SAMSUNG_USB_Driver_for_Mobile_Phones.exe[/font] and go to [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]7-Zip > Open archive...[/font]

Hit Extract and it should extract to a directory with the same name.

Open that folder and find the [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Uninstall.exe[/font] and [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Uninstall_1.exe[/font].

If you're on a 64-bit installation, right click [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Uninstall_1.exe[/font] and select [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Run as Administrator[/font]. Otherwise, instead select [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Uninstall.exe[/font] and do the same. (Google the way to find it if you are not sure).

Let it uninstall.

Now go back to your Downloads folder and right-click [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]SAMSUNG_USB_Driver_for_Mobile_Phones.exe[/font] and [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Run as Administrator[/font]. This installation seems to take a very long time for some reason, don't panic.

Once that is done, you (hopefully) have drivers now! Plug in your phone and you should see [font="Segue UI,Arial,Helvetica,Helvetica Neue,Lucida Grande,Verdana,Roboto,Droid Sans,sans-serif"]Installing driver software... and it works![/font]
