I finished my nand mod, but now I have an issue. I do have a9lh. When I plug in the battery and press the power button, nothing happens at all. When I plug it into a wall, I can see the charging light. If I try to turn it on while plugged in, the power LED does a really quick and faint flash. I have checked all of the ribbion cables and redone them 3 times. Has anyone else had this issue and found a solution, or do you have any suggestions?
