Hello Fello Techies!
Just as promised I am back with my very first Tech Tid-Bit! As a repair technician I always find new and exciting things while fixing up all these gadgets and I feel like I have enough information to share to last a lifetime! For now I will just be sticking to what I found most interesting from the last week.
Well here it is. Repairing the wonderful iPhone 4S. For some of you this repair is very straight forward and easy to do. If you have never done a screen repair before I don’t recommend attempting it unless you have full knowledge of what you are doing. It can be very disheartening to damage the logic board or other components inside the unit. Needless to say no matter how good you think you may be at repairing the screen on this device there seems to be one small issue that simply puzzled me. I would power the unit up, test all the functions on the unit and WHAM! The sim card would not pick up any sort of signal. The iPhone continued to just say “Searching”. Thinking there may be an issue with the customer’s sim card, I went ahead and installed my very own sim card and it still would not work. “Uh-oh! What did I do? Did I ruin something? Surely not! I’m an expert! This could never happen to me!”
Sure enough, there happens to be a small software issue with the iPhone 4S that causes this issue when you unplug the battery from the logic board. Does it happen every time you ask? No it doesn’t. But when it does happen I have found a solution to get the logic board to recognize the sim card.
With the iPhone powered on go ahead and remove the sim card and sim card tray. Once the sim card has been removed go ahead and shut down the iPhone until it has completely powered down. After the phone has powered down go ahead and install the sim card/sim tray. When you have done this go ahead and power the iPhone back on. The iPhone will boot to the main screen and will continue for about 30 seconds to say “Searching”. After those short seconds of waiting you should be receiving full service and your carrier should be displayed in the top left corner.
After figuring this out my blood pressure sure did go down and I was able to breathe a sigh of relief. I’m sure some of you out there have had this issue and I’m sure you all were wondering what could have happened. I hope this little Tid Bit of knowledge will help some of you techies out there. If it doesn’t there certainly could be a bigger issue.
