Underneath the resistor is 6 very small points. If that was to fall off upon removing the cable, it will not read a sim. also if it is reading sim card, but still "searching" or "no service" (sometimes switches back and forth) the small blue resistor may have been been detached. Or the smaller resistor next to it. Both are located by the signal cable (which is connected to the loud speaker) may need a new motherboard.
Hat geantwortet auf: No network or Wifi connection and power problemsHi lindsey! Ive seen this before. I had a severly water damaged 4s. I replaced the battery for starters, (which most always goes bad after being wet) once I got the phone functional again I noticed the wifi was grey and bluetooth would not connect at all. Which I hear is common with ios 7. not in this case. I tried to replace the signal antenna, no luck, replaced the wifi antenna, no luck. Yes I also tried the hair dryer as a last resort and still nothing. Thag is only a temporary fix anyway. What I believe it I is, is a bad wifi chip. The corrosion and contaminates from water stays on the motherboard causing a bad connection to the flex cables. It can be cleaned off, but the wifi chip cannot. a new one must be soldered into place. The easiest way is to buy a $50 motherboard or pay $100 to have someone replace the chip. I hope this helps. Its a lost cause lol good luck!
