iPhone 4S "No Serivce" - Logic Board Damage Need Identification?
I have an iPhone 4S where there has been damage to the logic board and has resulted in having "No Service" (just cellular).
I have already soldered a jumper across where the blue coil (blue circle) should be but i have now found more damage and would like identification (capacitor, jumper, resister or something) and how to repair (simple solder or parts needed) of the circles in the image (orange and red).
Here is a picture of the logic board
Any help would be appreciated. Thank you.
So i opened my iPhone again and i was able to find U21_RF stuck under the battery. So i placed it back and was able to get a signal again!!
Now for the C17_RF, the shipping is just way too expensive $39 for a $0.10 item.
Does anyone know what that capacitor does and if i have to replace it at all??? because the iPhone seems to work for now...
from australia if anyone can help with finding a cheap shipping.
Is this a good question?
