JuopunutBear is the first release from team Unlimited.IO. It is a tool for gaining (radio) S-OFF and flashing a custom bootloader that supports full write/erase fastboot commands on a number of HTC phones.
JuopunutBear does not provide root access, however with S-OFF this is a simple process of flashing superuser from recovery.
JuopunutBear comes with NO WARRANTY (express or implied), and NO GUARANTEE OF FITNESS for any particular task. We have made every effort we can to make this a safe process for users however the authors disclaim any liability for damage to your phone or other materials or devices used during this process.

Follow the on-screen instructions from ControlBear.
Do not press any of the buttons on the phone during the process.
The "wire trick" is an essential part of the JuopunutBear S-OFF procedure.
Obtain an insulated wire of appropriate length and gauge. Suitable wires are: a SINGLE core (strand) from an ethernet cable or a core from a coaxial cable.
Pick our your device from the link below and click on it. This will open a new window with the image for the PIN and GND points needed for completing the wire trick.
When instructed to do so by the program you must perform the "wire trick" as follows:
Hold one end of the wire into the hole where PIN is indicated in the picture below, ensuring that a firm contact is made with the metal contact at the bottom of the hole.
Briefly touch to other end of the wire to the contact marked GND in the picture.
Wait approximately 1.5 seconds and then again touch the wire to the marked GND.
* If that timing does not work the first time try: TAP (pause 1.25 seconds) TAP
Allow the program to continue.
IMPORTANT: If you get the error Still Sober all you need to do is re-run ControlBear after you have verified that you meet all of the pre-requirements.
If you're having problems check these troubleshooting steps.
Don't know if your HBOOT is GB or ICS?
Support for JuopunutBear is on IRC channel #unlimited on freenode. If you do not have an IRC client you can use the link below.
While it is possible to gain S-OFF on using any current version of android on the HTC Sensation Evo3D and MT4GS, we encourage you to use the revolutionary tool if your device is on a supported HBOOT. The revolutionary tool is a simpler process for the end user than JuopunutBear.
