I just flashed two white european DSLs and I can tell you that my heart nearly stopped beating. First when I tried to short SL1 nothing happened. Suddenly it went to 2% and then nothing for a few minutes. I got so nervious at that point but kept cool, at least it didn't turn off. So I moved my tool a bit around and boom, it went straight to 100%. The second DS was easier cause I knew how to stick my shorting tool into the hole.
