NO SIM Card bad soldering job
Hey guys, friend of mine brought me this phone without working sim (no sim message in the left top corner). Immidiately after openin, I've recognized something bad about the sim card reader, it’s full of connected solder.. any idea how to repair this stuff? I’have microscope and soldering and hot air station.
That’s what I’ve found underneath. Is there a possibility to repair those pads?
