Impressive. So much effort to repair a budget phone. I ordered new screen assembly and spent so much effort to work on my faulty A12. Turns out, the new screen can only barely see anything. Better than old one which no display at all. So now, I suppose the mainboard is the issue. I don't have microscope or workbench lenses. I pried out the shielding and try to look around. Nothing seems burnt. Maybe one or two 1-2mm sized capacitor or what. Then, I feel it is not worth the effort. I'm an IT Engineer, not electronics nor electrical trained lol. So I got no confidence in using heat gun and swap out these nano components. I'm tossing the mainboard out. And will try to sell the screen assembly replacement cheap on Carousel lol. It's a waste to throw a working screen assembly, and sim card tray, and the 5 camera modules from the mainboard.
