Often, users have trouble rooting and unlocking their devices, especially when there are many different tools required for the job. Things are no different with the HTC EVO Design 4G, but things are about to get a whole lot easier thanks to an all-in-one tool.
Thanks to HTC Super Tool by Senior Member frigid, you now have one program that does it all—root, unlock bootloader, and so on. Most people who want to unlock their bootloader proceed directly to the HTCDev Site, which is exactly what HTC Super Tool uses as well. The famous zergRush root exploit is used for acquiring root access, and should thus work on more than just the Design.
One of the biggest features of this tool is that it can remove the love-it-or-hate-it Sense UI from your device. This is a great feature for those who dislike Sense and those who simply want to experience their phones without it. Don’t worry, though; you can add it back with the tool as well. The last feature allows users to add wireless tethering.
It is quite possible that you will never use all the available tools, but perhaps you will. Head over to the original thread for instructions and downloads._________
