It doesn't work for me.
When pressing on Start, it begins and the message indicating that "MD5 hash value is invalid" appears. So the process ended.
I don't know what to do now.
I already root my T989 with "Unlock Root" and it works fine. So I decided to modify the "fingerprint" for buying on "Android Market" because I am in French Polynesia.
After reboot, it bricks.
After searching on the web, I found another .TAR file, the one for my IVKID phone, and not for the UVKL1.
I relaunch the procedure and now it's continues the procedure.
