DirtyRacun achieves S-OFF without the downgrade on HTC EVO 4G LTE
If you upgraded your phone, or your phone shipped with a newer HBOOT, you’ve had only one option for S-OFF: booting into a Linux OS, temporarily bricking your phone, and rolling back the HBOOT to then be able to root with Panda. Fortunately, Unlimited.io has now released a direct S-OFF application for HBOOTs 1.15, 1.19, and potentially future versions, as well.
Going by the instructions, to get the DirtyRacun “rabies shot,” you’ll need a 32-bit Windows 7 or a 32-bit Ubuntu OS running. You can use a Live CD to accomplish this without having to mess with your real operating system. You cannot do this in a virtualized environment, you can’t do this with the much superior 64-bit versions of these operating systems, and you can’t do this plugged into a USB hub.
Your phone will need to be HTC locked, which is how it shipped. If you unlocked it, there are instructions for relocking. You’ll also later need to use the HTCDev unlock site at one point, as the DirtyRacun will require it. Finally,you need a microSD card of at least 2GB or greater
Out of 15 steps, it appears the first ten are just RUUing back to stock, the eleventh is getting and flashing an unlock token, the twelfth is not doing something, the thirteenth is enabling USB, the fourteenth is just running the program, and the fifteenth is waiting for reward.
I have my questions on the need to RUU back to stock, or the whole lock and unlock process if you’re already unlocked, but I guess it’s better safe than bricked. Quite possibly, this is something that only exists in a first boot state of a stock ROM that they’re exploiting.
If for some reason the process messes up your phone, they have also made a recovery tool to take those QHSUSB_DLOAD bricked phones and inject them with a shot of adrenaline to bring them back from their reprogramming state slumber.
Since, I’m already S-OFF by the panda on my EVO 4G LTE, so let me know how this works for you if you decide to try it.
