The screen's connection was fine, I tried unplugging and retrying a few times, same result. His screen working fine with SP shouldn't seem odd. The screen is just made for the SP's voltage source, connection cable etc. So it may show better results within its original set of structure than an adaptated one by force. But when it's no genuine product, side effects may occur it seems. In general, knock-off or not, it working in SP fine and in agb not, wouldn't necessarily mean that the screen can't have problems.
Well the deal there is that he sees his work's result -and who would know better than him that if the modification functions properly or not- yet he still ships it in that condition. What would you think of that?
Also when I open the situation to him, he says that it's normal that it has low light, that that's the expected result because of agb's nature (in simpler english). Though there are people who got functioning ones and also I made mine into via replacing the screen with a genuine one.
To sum up, I don't like all this at all...
