So basically I updated my ak2i from 1.8.6 to 1.8.7, and then it made my ak2i get a black screen. After going to the akiao forums and downloaded it, I tried to put my ak2i into the ds, and four hours now it's been unable to show up on my ds. If it's of any significance, the ak is genuine and old. The golden strips on the back have black lining on them that seems like something dirty but they can't be cleaned off. The two end strips are extremely dark compared to the rest. A few of the inside strips also have tears at the end. The holes on top are fine though. Is the ak not showing up because it's in this condition which I can't seem to clean?
