Great news for all of you that have updated your device to HTK55D.31.5.0002 US HC 3.2.1 OTA ROM Update and lost the ability to root. We have now found a way around this and the ROM update is now fully rootable. You can get the tool here: The tool will do the following:

1. Install a temp root exploit.
2. Flash a new bootloader on the device that will put fastboot nack in the recovery menu.
3. Flash a root enabled boot image to your device.
4. Install the su and busybox binaries.
5. Install the superuser.apk app.
6. Create the simlinks required for busybox.

Enjoy the tool and happy rooting.
