My mobile charge bin problem how to find that problem , no charged my mobile…
Removing the motherboard is unnecessarily difficult on this model! Why make it like this? One would figure the screws would do a good enough job of securing it to the frame. I guess having to wiggle it out is just part of the fun, right?
Also, getting parts for this model (and it’s water-resistant twin) sucks. I’m currently in the market for a display+touch assembly and it seems I’ll have to resort to importing from AliExpress.
