iPhone 4S WiFi problem – new ios

On March 27, 2015, Posted by , In iPhone, With Comments Off on iPhone 4S WiFi problem – new ios

Hello,


Im purchaseing iPhones to repair them and sell them again.

I bought an iPhone 4S Along with a greyed out WiFi and I always reflow the IC and it always works, but this one didnt even had an IC on it.

It is having some damaged pads where the WiFi IC sits, but I dont know if it can be even resolved?

Putting a new IC on it didnt work and it is still greyed out.

kindly to be helped

Kind Regards

    Do you have photo to see the damaged pads , how many pads are removed

  2. Wela says:

    ughh I cant upload a photo because of my postcount -,-

    But it is missing about 10 small pads

    They are all on the side, the middel ones are still preserved

    Hoping it can be fixed :/

  3. Phil says:

    If you never did it this will be hard to do , and for 10 pads its hard any way and will take a long time

    So you can serch in the internet to find and bay a silver based epoxy , use it to replace missing part

    But before you have to scratch carffuly the pcb were the pads are missin until you see the copper link

    My advise is sell the phone as only 3g working , no wifi

    Ughh here in my country you get nothing from a iPhone Along with no WiFi

    I think Ill just try to fix it.

    Can you recommand any products or techniques?

    Do I have to scratch until I see copper and then put some silver based epoxy on it?

  5. kijiji says:

    Yes but real carffuly , search and you will find how to repair missing pads

    And i have no recommand product

  6. killu says:

    I scratched most of the pads and you can now see the copper.

    But some pads also have the copper layer removed?

    Because I dont see them

    Is it possible to have WiFi Along without some pads or are ALL pads required?

    Yes I know that works, but kindly look carefully to my question and maybe youll understand it title=smile

    use the schematic of the 4S to know whiche pad is important , look to U1_rf compare the 60 pin to the schematic and you will find

  10. wagny says:

    are the one Along with a colour in the schematics the important one?

  11. TechGuru says:

    gold color is important , if you have the schematic Along with gold and grey

  12. sulmanz says:

    Yes almost all the missing pads happen to be gold ones -.-

    I think I just give up title=frown

  13. chugowa says:

    Waste of time… 10 pads it is suicidetitle=smile it takes to much time to repair and you dont have any warranty that it will work when you put ic on it… Try to sell Along withou wifi and purchase another one. Ive tried to restore 3 pads but everytime after i put ic it wont work…
