[Q] Need advice upon a hardware damage.
Ok, I made a stupid mistake while I was assembling my N4 back, after replacing the screen. I damaged one small part of the motherboard. 3 small things where ripped off ( shown on the first image ). As shown on the second image, I damaged some connection parts of the Avago 3012 Ultra Low-Noise GNSS Front-End Module. The first month after assembling back, I didnt notice any problems. But the first problem was that the battery dies when getting at 20-15% level, if forced too much with a game or any other apps that load the phone too much. After 2 weeks another problems appeared. The wifi signal became very bad. It doesnt reach all the routers around, only the ones close to me with a very good signal.Sometimes it even freezes until reboot. It stucks on same found signals and doesnt show anything else. Times by times, even the gsm band turns off completely as if its on Airplane mode. I've read online that this low-Noise chip somehow reffers to wifi and gps but can it somehow affect the battery? The second problem is that after asembling phone back, the back cover doesnt close fit enough. The left middle side of the battery became too blowed up, and it takes some space to close the cover completely so it remains a little opened. I have no ideea how it changed it's shape so suddenly. So my last question is: is there any chance if I ask a master to solder these three small pins. It will work back? Or the Avago chip is already damaged permanently?
