T-Mobile MyTouch 4G Completely Free; Radio S-OFF Achieved

T-Mobile MyTouch 4G - Radio S-OFF

Last month we were greeted with the perma-rooting of the HTC Desire family of devices, and soon-there-after, the T-Mobile MyTouch 4G. Today, XDA-Developers forum member, grankin01, takes it a step further with Radio S-OFF.

You might be wondering, “What’s the difference between S-OFF and Radio S-OFF?” To best explain this, here is an excerpt from Radio S-OFF thread:

Now, you may be asking “Why do this? I already have root from your other guide and it has given me r/w access to system and recovery. I thought this meant we had permanent S=Off.” This is only partially true. We have had an engineering bootloader and “Label” s=off not radio s=off. When you turn the security off in radio it is off permanently no matter what hboot you have installed engineering or otherwise. However, it is optional but you can still copy the engineering hboot over and it will allow you to flash whatever you like without (as much) fear of bricking your device.

“But, what are the advantages of Radio S-OFF?”

  • SuperCID, which allows you to flash any carrier’s ROM to your device.
  • SIM Unlock, which allows you to use your phone with other carrier’s SIM Card, such as AT&T.
  • True permaroot, a.k.a full access to your device.

Along with the advantages, there comes the impending possibility of messing your device up beyond repair if you are not careful, Now if you feel you’re ready to dive in and try it, hit up our source links below.
