Product little used. Once formatted to make it 1 bootable, she began to experience problems. She was no longer recognized my car. Then it is simply setting "write protected" herself. I spent hours searching for solutions on the net. It turned out that the key is screwed. Only one flash could solve this. But could not find the software that can flash on the Russian sites. I ended up breaking it, to avoid losing more time, and she ended up in the trash.
