Many Samsung Android users rely pretty heavily on Odin or its Linux / OSX counterpart Heimdall. This isn’t an overly big deal as both applications are stable for the most part and do the job. However, if you’re going to be rooting and hacking your device, you should probably get used to things like Terminal commands anyway. Aside from the obvious fact that learning such commands are useful, learning to use them can mean not having to increase your flash counter any more than absolutely necessary. T-Mobile Samsung Galaxy S II users can now do this by installing recovery from command line.
Written up by XDA Senior Member PorchSong, the method is pretty easy to follow. Users are directed to go to the official ClockworkMod Recovery website and download a recovery image for their device. From there, place it on your internal SD card, and use Terminal Emulator to flash it.
Aside from showing users how it’s done, PorchSong also explains what the commands mean. So if you choose to follow the guide, you’ll get acquainted with the dd command and its usage. Learning anything regarding Terminal can be potentially useful for anyone with a rooted Android phone. Additionally, this method could be used on any Samsung device. All you’d need is the proper recovery image and the location of the proper partition.
