Last time when I just bought it, it works.
Just tried it today again on my SGS2 and it cannot reset the counter and yellow triangle is still there...

Note: I flashed to XXKI3 today...and the USB Jig Dongle cannot reset the counter nor remove the triangle...sad...
Just checked and you did not buy the jig from me. I'm sorry to hear about that.
There could be several possibilities.
a. You may be using the new bootloader.
b. The resistor in the jig has broken.
I was informed by a buyer during COD that he is using KI3. He tried the jig and it works.
Perhaps he is using the old bootloader.
Maybe you would like to search for more info in XDA.
