    Default Reparing older 1st Gen Iphone - bad reception

    Sorry, posted this in pwange section when it should be here

    So I am a “DIY” type of person….

    When my 1st Gen Iphone LCD broke, I bought parts to replace it. Long story short, here’s what happened

    1) replaced LCD screen
    2) attempted to replace battery as well (bad soldiering job but got it done)
    3) ripped wifi cable while closing the case
    4) bought new and replace wifi / cell antenna
    5) Upgraded to 2.0.2 software (bad reception)
    6) downgraded back to 1.0.4 software (still bad reception)

    I really don’t know what other part there is to replace. While standing still, the reception is fine but when the iphone is on the go, it loses reception quickly and conversation fades in and out.

    What else could be wrong? I spent so many hours working on this I just hate to throw this phone away or sell it for parts. Should I try the Antenna Flex Cable

    You may review the connection of the short white cable to the commboard and the antenna.
    Remove rubberlike resin that surrounds the connector. Do a clean connection and verify the signal strength before closing the case.

    Thanks for your reply.

    I ordered a new antenna so the connection going to that will be clean. As for the commboard, I will give those small circles a good scrube and pick (not sure how you would clean it, I am paranoid and scared of damaging it).

    Why don't you check this out. It's a guide on fully disassembling iPhone. It's very useful. It's not only described with writings but also pictures so you won't be confused. And here is the best part. They warn you if there any risk on the part your disassembling so that you will replace your iPhone correctly.

    Good luck with the correction.

    Use a plastic spudge or something like that to clean and remove that rubberlike glue. Be carefull to not scratch the PCB.
    If you want a pro finish, use isoprophylic alcohol. It will help to that, but make sure to dry it completely before resoldering the battery.
