While rooting a device can sometimes take forever, in most cases root is obtained pretty quickly by our talented developers. Of course, the question then remains how difficult is that root process. Sometimes it’s just flashing a couple of things, other times you might be navigating a labyrinth of ADB commands. In some cases you may even have to become facile with Linux, although in most cases there’s at least Windows and Linux support. For the Samsung Galaxy 4G, you get both.
XDA Senior Member lumin30 has released a root method that works for all Windows machines, but the bigger focus is on the 2nd post of the thread, which teaches users who have Mac and Linux how to run Heimdall so root can be obtained on all three. The guide is more intense than one might imagine as the original Galaxy S 4G came with Android FroYo. This means that the first order of business for users who haven’t yet updated to Gingerbread is, of course, updating to Gingerbread. From there, it’s a relatively simple process.
The guide also runs users through how to backup their EFS, which is very important because it determines your device’s IMEI. Additionally, lumin30 is nice enough to include links to a few of the more popular ROMs, tweaks, and mods so new to the Galaxy S 4G forum can pretty much get to wherever they want to go through the guide.
If you’re new to the device, be sure to head on over to the original thread for more information.
